An hour on this bicycle will give your house enough power for 24 hours

Just imagine that you can workout for one hour at home, and that workout will generate enough power to supply your house of electricity for 24 hours. Now that is what I call great.

In the video below, you will be able to get a good view on how the bicycle works and how it is possible to generate electricity at home while simply doing your daily workout.

Have you seen:

The best thing is, the workout can be split to multiple people. Allowing you to workout with friends while they generate power for your house (muhahahaha – evil laugh).

    I’ve often wondered why gyms don’t harness their stationary bikes and other equipment to collect “free” electricity from their customer’s workouts. But you’re kidding yourself if you think that one hour of exercise a day will power your house for 24 hours. Do the math. If you consume 2000 calories a day, that’s equivalent to 8374 Watt-seconds (see https://www.unitjuggler.com/convert-energy-from-cal-to-Ws.html?val=2000 ). Divide by 60 twice (seconds to minutes to hours). Divide by 1000 (Watt hours to kilowatt hours) and you get…

    0.002 kWh.

    Enough power to run a microwave oven for eight seconds.

  • Dph

    Not right, Scott. When we talk about food, we’re talking about Calories (big C), which are actually kilocalories (small c). You’re off by a factor of 2000.

  • Dph

    1000, I mean.

  • Scott Snadow

    Right you are. (It’s been a LONG time since I studied those things…) Anyway, cross-out my last “Divide by 1000” step, and the number becomes 2.32 kilowatt hours, which – while a significant amount of power – is still not going to make much of a dent in a typical home’s power consumption. Especially since that’s for a full day’s worth of food intake! Scale it back to about 500 Calories for an hour of exercise, you’re now down to 0.6 kilowatt hours – or about a third of the electricity needed to run a house for 24 hours…

  • Jason Wright

    I have had the idea about the gyms for awhile now. You could record how much electricity a member generates, then deduct a corresponding amount off their dues as incentive.

  • Chris Thomas Wakefield

    But to think that living our current humongously electrically-wasteful ways will be supported by such a progressive, but currently limited, method of generating electricity for storage, is a complete fallacy. People today have no clue about living with minimal electricity, NO CLUE. It’s the same with water, but that is another post/time. What is reasonable, is one or two lights on at night, maybe using the modern technology of LED-lighting would extend the number of light sources, running a fan, a blender or even a washing machine, but to use electrical-gulping appliances like microwaves, radiant heating, electrical cook stoves is out of the picture entirely.
    We have been unconscious users and wasters of electricity and water for the total period of late-modern man, with perhaps the exception of the late 1800’s. A big reality check is coming.

  • GorgonVaktmester

    Actually you are not far off. A professional athlete can maintain a power of 5-600 Watts for an hour. For the average Joe this is more in the order of 100 Watts. 100 Watts for an hour makes 0.1 kWh, or enough to run your microwave for 6 minutes. This is without accounting for loss, so the actual figure is probabl closer to 1 or 2 minutes.

  • Dag Inge Hansen

    You can produce 100-200 Watts on a spinning-bike, but for one hour you would get 0.2 kWh maximum. Enough to power two LED-lightbulbs for 24 hours. Not more, and you probably need at least 2 kWh for heating the water used for showering your sweaty body…

  • cek11

    You folk aer talking about “typical” US households where this inventor is talking about people with energy needs much smaller than us. Of course, the title of the article itself causes one to think that.

  • Gordon Miller

    Look, face it, man. It’s just not possible to fry an egg using a
    bicycle-powered hair dryer.

  • ToddSmyth

    Right but if you are exercising and showering without generating electricity it is a bigger net loss.

  • Jay Tilton

    So… solar panels, a bike that produces energy, solar hot water, and r 38 insulation in the walls will pretty much drop or offset your consumption by 100 percent.its true I already did I it. Well except for the bike. And I am willing to try though. And I do think that is really the point.

  • Jessica Z

    According to the video the machine will generate 1050 watts in an hour of using it. Granted thats still only 1.05 kwh whereas the average home in the US uses approx 30 kwh a day…

  • Alex Hollabackatcha Parsons

    Fuck cycling to power your house can’t be assed or have time for that, put a motor on it.

  • Rowena

    Some gyms do, including: http://5050fitnessnutrition.com/#

  • thieso2

    Have a look at how much cycling is needed for a single slice of toast. https://www.youtube.com/watch?v=S4O5voOCqAQ

  • Jake Hill

    Right? What an absolute bastard. Trying to create something to help less fortunate countries create their own energy. He is such a fucking prick.

  • Scott Snadow

    BINGO! Title of the article (or maybe it’s the headline, written by someone other than the author) is “An hour on this bicycle will give your house enough power for 24 hours.” I’ve got several CFLs and a few LEDs (and changing more lighting to LEDs as time goes on) – but an hour of riding a bike isn’t going to power my home for 24 hours, unless I’m not there. (And then who will ride the bike?)

  • John Bevilaqua

    Be wary about some of this guy’s overstated claims. This machine costs thousands of dollars and only generates about $5 to $10 of power a day which must be used right away. And how could this have been used during KATRINA. with 4 feet of water in your house?

  • John Bevilaqua

    This charlatan has another hair brained idea to solve California’s drought forever by installing desalination barges offshore which can convert seawater to drinking water but at what cost per gallon? About 50 cents per gallon which is almost $2 million per day just for the Orange County shortfall. He plans to make this process more efficient by 2020. By then California will be a desert like Las Vegas.

  • John Bevilaqua

    Energy can not be generated from thin air unless you have wind turbines using free air like Denmark. He is a charlatan.

  • John Bevilaqua

    It took an Olympic Gold Medal cyclist over 3 minutes on a bike to run a 2 slice toaster. And he was pooped at the end. And he probably burned as many calories as were contained in the toast in the process. Energy can not be created or destroyed merely converted from one form into another. At the end he said: “This is nuts!” While collapsing on the ground.

  • Anthony

    Calories in food are measured differently than “calories” in physics.

    If I remember correctly the ratio is 100 ‘physics-“calories”‘ to every one metabolic “calorie”

  • John Bevilaqua

    This charlatan has another idea about drilling into the earth’s core to extract energy from the magma found there. But he has no answer how to prevent his drill bits from being destroyed, or how shifts in the earth’s crust can be controlled, or how to prevent these graphene fibers from being ripped apart, stretched or melted. Another PT Barnum in the making. He invented the 5 hour energy drink and has Billions to waste. And waste it he will.

  • elkel

    I farm a rural homestead, selling produce for cash to pay the taxes. I have grid electric and use 4 kw hours a day including running a strawbale walk-in cooler for the raspberry harvest season. Our grid electric often goes down, due to the rural nature of things here, and a bicycle that could provide 4kw hours in one hour would save a lot of food and provide more consistent sales.

  • acuvox

    You are confusing calories (heat) with Calories (chemical) Big C Calorie = 1,000 lower case c calorie. You generate enough power to run a laptop, cable modem and an LED lamp while you are exercising heavily.

  • Irish

    I will happily take one for free and write an awesome review about it… haha. No-but-seriously-I-want-this. Props to the guy for wearing a nice shirt and sweater while working out :-). Love this man.

  • Fu Manchu

    The looming question of course, is how much does one cost? These technical solutions, while admirable, are meaningless in the face of a titled economic system and overwhelming structural violence.

  • ScottAg83

    Yes, become part of the matrix.

  • Michael Birkle

    One of the hidden costs in devices used to save energy or produce energy is the energy cost of actually producing the item itself… take a refrigerator that will save you a few Kw a year sure we can calc the cost per Kw and then see the pay off verses purchase cost but thats economics not reflective of the energy cost to produce it? it would be nice to know the energy costs of manufactoring to be able know the point if any the energy savings off sets that cost.

  • Mark Tunn

    Oh They are starting to tax the air next year

  • quirkasaurus

    Yes, but don’t forget the initial investment in those generators… the wiring… the storage cells… the maintenance costs… all in all, this pushes the ROI out about 25 years.

  • Will Stewart

    False. The average person *might* be able to generate 100 watts for an hour, but that wouldn’t even power the refrigerator for that hour, much less the TV, lights, HVAC, computers, etc, etc.

    http://www.lowtechmagazine.com/2011/05/bike-powered-electricity-generators.html

  • Will Stewart

    1050 watt-hours? No one has that much stamina. No one…

    100 – 200 watts for an hour? Yes. But that is 100 – 200 watt hours

  • Rj

    The fitness guru (now Brick)in dumbo, Brooklyn utilizes spin classes to generate power for the gym. A few years now.

    Don’t get me started on his graphene “inventions”.

  • Persephone Abel

    You forgot that a calorie (lower case “c”) is not the same as a dietary Calorie or kilocalorie. You would actually generate 8.4*10^6 Watt-seconds. That is, assuming you cycle long enough to burn 2,000 Kcals. πŸ˜‰

  • ecowheelie

    Dixon Recreational Center at Oregon State University does.

  • I think if we could generate electricity from mouse clicks on our computer, that eventually all the mouse clicks added together from clicking on click bait on FB could power all developing nations. If you don’t believe me check out buzzfeed….

    Edit: However, I enjoyed the math in the comments…

  • Brandon Dillon

    its not the person doing that much work its the generator..

  • Cawrl

    ^I think you missed the point of power-source and electrical generators.

  • Bob Smiton

    Most just don’t and more often than not, simply refuse to understand that you cannot create energy. You can only transfer it, generally at a substantial loss.

  • Robert

    Many gyms already do this but the bikes barely generate enough power to light up one of the lights in the gym bathroom. At least they arent wasting the energy to the air! Neutopia ecoSolutions inc pays people to find buildings that could use their systems, from $100 to $5000. The Energy Recycling System is the world’s first solution of its kind and guarantees the exact amount recycled and your financial savings prior to investing in a unit too. Every gym in the world could use one and cut their bills as much as 50%, since it makes energy, recycles energy, stores electricity, even makes and stores hot water and ice…plus 100% of their profits go toward social impact projects. Nothing else comes close to fighting climate change, all at zero cst to the building owner!!

  • Mike Lashewitz

  • Anton Louw

  • Kevin Bruce

    well for a 3rd world situation that light means the kids can read and study and better themselves. which they could not otherwise do, so… ROI could be much less if you factor in lost oppertunities.

  • Slugo

    Humans by nature are lazy and waste everything they have access to of more than what they need to survive, procreate or be comfortable.

    Take for example you wasting electricity to write your post, there is no need for it, because nobody cares, not even you, it’s just a wasteful pastime because your house is not on fire and your refrigerator is not empty.

    Humans only care about what benefits them personally, period. They will not bicycle a generator to give anybody else power, but they will contemplate pedaling a smaller easier one with less effort to power their iPhone so they can Facebook and waste more time. That is if they can’t get their hands on a solar phone charger to make life easier.

    If electricity was this easy and simple to get, the world would be fully powered by now.

    Let me restate that;
    Electricity is this easy and simple to get, it always has been, ever since Faraday and Schwinn showed up, people are just too lazy to burn the calories to get it, especially when they don’t need light to nap away the day.

  • Slugo

    He plans to run a water pipeline from the desalination barges to Las Vegas to turn the desert into a rain forest and save the planet after he hires all the illegal immigrants who were laid off from the dried up tomato fields to bicycle the generators to run the pumps 24/7

  • Caroline Carlson

    There are gyms in Japan that do exactly that. All the electricity is fueled by the exercise equipment.

  • Garyth

    it is not the person who has to do all the work. if the fly wheel is big enough it can generate that much power. but not enough to power a house in whole.

  • Slugo

    How many days will it take to get a mile in a Prius?

    Just wanting to know as this is the crowd who will be buying these to carry in the trunk when they run out of fuel.

  • Patsy McMichael

    If your one hour on the bicycle can charge enough batteries, and your usage isn’t wasteful, then the inverter/converter will convert the 12 volt to 120 volt and supply your house. Of course if a person already has solar panels, then, this bicycle would also make up for cloudy or rainy days and snow in winter.

  • Redorblack Nigelbottom

    Flywheels do not generate power, they store it as kinetic energy. So you have a person expending about 150-200 watts of energy to slowly spin up a flywheel and generator to generate electricity which needs to be stored for future use or to even out the load during simultanious useage. You can’t make 1050 watts per hour while expending a 1/5th of that. There is nothing new here, a company in CA sells a similar system where they tie the output together of a bunch of bikes spinning generators to power concerts.

  • Patsy McMichael

    You would be charging a bank of batteries….which, in turn, are providing your house with power…..your peddling alone for that time is not powering the house. Sure, the more power you use, the more power you must recharge….but….in a poor community where everyone contribute their time on the bicycle…..life would improve greatly.

  • Slugo

    never thought of it that way…..

    How come they need the pedals on the bike if it turns itself?

  • Patsy McMichael

    He isn’t talking about the average home in the US…..he is talking about communities where no one has power at all…..never…..an in the event that an area of the US finds themselves with no power due to a storm or something. Most of the people he is talking about live in a one or two room home…for that, 1.05 kwh would be more than enough to add a computer to learn and be educated with.

  • Slugo

    oh yea? Just ask the guy driving the Prius and selling the bicycle generator

  • Andrew

    if the purported users are poor how can they afford the machine?

  • Slugo

    They are free,

    Just put an ad on Craigslist in the wanted for free section for a “Schwinn exercise bicycle” and a “used washing machine”.

    Every other house in America has one of the two in their basement collecting dust they will gladly donate for you to haul off

    Get the generator out of the washing machine and hook it up to the exercise bike and you’re off to the races.

  • Patsy McMichael

    Wow. I have read all of the posts here. I am amazed by how many people are so quick to say something can’t be done or to find fault with a man who is trying to bring one light bulb or one computer to a family with none. What are all of you doing to help other people living with no electricity….beside telling him it can’t be done…..anything? Have you created anything to make lives better….to give away….to people in a far away country?

  • Patsy McMichael

    He plans to give it away to them as a community. He will collect donations from people, companies, and other sources which care about the lives of the people in poor countries. It’s called charity.

  • criskross

    Well after reading all your disparaging remarks we might as well stop trying to find a way to help poor countries and just send in the gas companies to sell them oil. Hell what’s the use. Just give up, make fun of anyone who tries and throw it all away. Hell everyone knows only gasoline can generate enough power to run a damn microwave. Who freakin cares about a damn microwave, do you honestly think these people cook with one? Are you actually that stupid? Really?

  • I generate all of my own electricity. Mostly solar, a little bit of diesel power. This is bullshit. It says MY house. First of all, my house is a boat and my electricity usage is tiny compared to virtually any house that was built with electricity routed through the walls. What WOULD be my house if we were dirt dwellers. Still we use 200-300 amp hours a day at 12v. That’s about 3000 watt hours consumed. We lose about 30%- 35% due to the inefficiency of batteries (80% return at best) and losses in wires and power conversion or inversion. That means that we actually need to make about 5000 watt hours, 5 times what they quoted. We have a small keel-cooled refrigerator (no fan or water pump to run) fans to keep us cool, laptop and phone chargers, LED lighting, and an anchor light all night long. Really minimal to maintain a fairly conservative modern lifestyle. If they said “Generate Enough Electricity to Power an African Hut”, I’d buy it. If you want to convince me, don’t start out by lying to me.

  • Slugo

    it claims “An hour on this bicycle will give your house enough power for 24 hours”

    Will there be enough power left to charge the phone and call 911 for the resulting heart attack?

    You get one of these for free when you sign up for Obamacare

  • Slugo

    they can’t,

    but we can ship them all the Schwinn exercise bikes hidden away in basements and the electric motors/generators out of all the broken down washing machines in America with a screwdriver and an “assembly required” sticker in 40 languages and the world will be fully powered up by next year

  • ken_winston_caine

    I live on minimal solar electricity. Have for all but five years since the beginning of the ’90s. I live on less than 1,500 watts per day. Run my laptop 12 to 16 hours daily. Along with a modem and microwave-dish wireless internet connection. Keep my cellphone charged. Have efficient LED area lighting in each room used as / when needed. Run a 700 watt blender for a few minutes each day. Have the radio on most of the day nearly every day.

    Run highly efficient fans all summer. Run a cpap machine all night every night.

    Am not a TV watcher, by choice, so don’t have to allow for that. Though I do watch videos on a netbook (which, real-world, draws 15-19 watts per hour).

    What I DON’T have or use is anything with an electric heating element. Use a propane fridge. And, by choice, do not use a microwave oven.

    Carefully shop all electrical purchases, reading the UL ratings, and real-world testing with a watt-minder device. Pay more upfront sometimes to get the most efficient, lowest amp draw version of an appliance.

    This is a lifestyle choice. Allows me to live in a beautiful, off-grid location in the Northern New Mexico mountains. I really don’t feel like I’m sacrificing.

    I know not everyone would choose or care to live this way. And I know it took my family about a year to master how to do it and to adjust to it. But it IS for real possible to live relatively well and comfortably in America on 1.5kw per day – – if you consciously choose to – – and locate in a climate thst doesn’t require air conditioning in the summer.

  • Joel Blayney

    Define “power for my whole house”? That’s an awfully vague variable to not account for.

    It depends on the road. Lets say it takes 1kWh, and you need to do 200W pedaling for 5 hours. 1kWh equals 85 grams of petrol energy.

    It’s a matter of physics. The energy produced by one person is negligible compared with almost any household usage.

    Your math for this example is also why gyms don’t harness power from their machines–it isn’t worth the effort.

    Anyone with a handcrank flashlight or radio will know just how much effort is needed to produce a miniscule amount of power.

  • wildsky

    Actually it’s already been road tested and is expanding. I don’t know if it’s this machine exactly, but entrepreneurs sell an hours worth of cycling power for $1 in african villages. This gives them the local equivalent of a day’s pay per hour, and provides poor locals with a cheaper source of light and mobile phone power than paraffin or other sources.

  • wildsky

    Good point- it shows just how absurd it is carrying lumps of heavy metal around with us when we move. The amount of wasted energy depends on essentially stealing energy and wellbeing from the future or other places.

    If we had to power our lives sustainably ( and most of us will have to at some point in the future), we’d be reluctant to waste it on cars, etc.

  • Aware

    It’s actually a really interesting video. But I’m glad that with your little math equations you’re obviously much smarter than the billionaire. Get a clue people. Watch the video before you make us all dumber with your commentsj

  • wildsky

    Thanks for the maths ( although you may be underestimating by 10^3- see later comment). But ,if I understand you correctly, one second of cycling would power a microwave for 8 seconds ? That’s a pretty good return, I’d say. One minute’s cycling to cook dinner ! Less depletion of rare firewood, less smoke induced blindness and respiratory disease. I’ve lived by fire- and it takes a LOT of time and effort. My lungs can’t take it either.

    Alternatively it means less burning of coal /nuclear, etc in richer countries. Brilliant.

    Of course ,they’re unlikely to have a microwaves in off grid villages, but such high efficiency would charge LED lights , laptops etc with even less effort.

  • Rick Kwan

    The article title and content are wrong. The video is probably okay. What the engineer says in there is “1050 equivalent watts of lighting”. It seems he is referring to ten 105 W equiv CFL bulbs, each of which takes 23 to 28 W. To power those, the machine needs to generate 230 to 280 W of power. Now… keep in mind, that’s just a demo. The machine is a prototype, and use in a 3rd world country would probably be configured differently. You probably wouldn’t use 10 CFL bulbs; you might power a comm link to some distant point, and possibly do something like wi-fi, or perhaps Bluetooth for lower power.

  • Jordan Jez

    By connecting a load (batteries) you will increase the resistance exponentially. Frankly it is not the best use of money (charge controllers, inverters, batteries) invest in solar instead.

  • wildsky

    By referring to heated showers- you put this into a rich world context, Dag ,in which people still need exercise, and would merely replace it with this, more effective version ( IMHO exercising with no purpose other than exercising is not motivating , and seems decadent). Those same people probably take excessive numbers of showers anyway as a matter of convention or because of using paper after going to the loo ( a rather ineffective method of cleaning for such circumstances).

    Most poorer communities would wash with ambient temperature water – if they had enough. And in that context these bicycles provide alternative employment to hard labour ,most likely.

    Overall- electric showers are not really relevant in either context.

  • wildsky

    In the African village context the batteries are already in the light holder or mobile phone, etc- the customer brings their own in other words. I could also imagine charging ordinary rechargeable AAA or AA cells, and selling them with a deposit.

  • Gordon Miller

    There is nothing you can do with the system to get more energy out of it than you can put in. That’s just the law of the conservation of energy – there is no getting around that. And since no system can be 100% efficient you’ll always be exerting more energy from the person than you can store in the battery.

    How many people live in the typical US home ? Presumably it wouldn’t just be , say the Mom doing the cycling ? Although I wouldn’t be surprised in some cases. 2000 Kcals is the minimum for a sedentary female adult. Physically active males might reasonably consume twice this, and heavy manual workers considerably more still. I’d be happy to convert a few extra mangos and nuts into power , whilst getting some of the cardiovascular exercise i don’t quite manage to get around to .

    A litre of beer probably has about 500 Kcals in it – what an excuse !

    I think the main issue that’s not being discussed is that he’s mixing the idea of well off people in developed nations who have time and energy to do daily exercise, with homes in third world countries.

  • Wasserstoff Lehrer

    This is a scam. The average American home consumes 11,000 kilowatt hours per
    year, or 30 kilowatt hours per day. An athlete cycling at their hardest
    for one hour can only generate around 800 watt hours, which is less
    than one kilowatt hour. A normal person casually exercising on a
    stationary bicycle is probably a tenth of that. So a person wouldn’t be
    able to keep up with the power consumed while biking, let alone generate
    power for more than that time. The BBC did an entire episode on this
    topic in their Bang Goes the Theory program.

    Nonsense. My Acer netbooks draw between 12 and 20 watts per hour — actually tested and documented several times over the last five years. The newer models use even less than the 2010 models. If living on limited electricity there is no reason to buy an energy-hog laptop. And 800 lumens, 60-watt LED light bulbs draw 8.5 watts each.(And I can buy them now for less than $2.50 each! And supposedly they will last for 22 years.) No reason to leave them on except when and where you need them.

    It takes a lot of human effort and energy consumption (calories/sugar) to power a house for 24 hours. For example to turn an on load 80 amp car alternator for one hour is very difficult to sustain even for the fittest people. 10 minutes of pedaling is a struggle to keep just one 20 watt light bulb on. Gearing and the flywheel can help balance out the load, however it still works out the same in the end. It would be better to invest in better photo voltaic cell cost per watt ratio improvements together with Stationary battery capacity and cost of production. I know a lot about these systems and I would like to talk to this guy before he wastes too much on greenie hype.

  • ken_winston_caine

    I’ve lived on solar for 18 of the last 25 years. At times with a small family. My systems are designed to sustainably produce 1,200 watts per day in the shortest sunny days of winter. I use on average 1,500 watts per day and live well and comfortably that way. (I do have a shortfall for about 40 days a year in the winter and have to conserve more or use backup power in that season to charge my batteries. And the shortfall could easily be remedied with a small investment in more solar production and more battery storage.)

    I know we each have different needs, but it is very possible to live in America on 1,500 watts of electricity daily (AND have wifi and a netbook running for 16 hours a day, and keep a Samsung Galaxy Note 3 cellphone charged, and have adequate lighting anywhere needed).

  • ken_winston_caine

    Vs. the cost of producing a not-so-efficient refrigerator? Let’s assume one is going to use a refrigerator. Are you saying the cost of manufacturing a more energy-efficient model offsets the lifetime energy savings versus buying/using the less-efficient model? I’d like to see the calculations for that.

  • ken_winston_caine

    The inventor didn’t title the article. Thanks, cek11, for helping make that point.

  • peterw

    That would be a very expensive way to produce electricity John. Hence the reason its not commonly done. The added cost of equipment and interconnection routines actually results in a negative gain. Sunlight (Solar/carbon fuels) and gravity (hydro) will always be the most cost effective means of generating electricity. Individual house holds or businesses are best suited to solar cells and stationary batteries if they either do not have access to a grid or they wish to cut off. Photo voltaic cells and stationary batteries will be more cost effective than converting gym equipment in any case. (Mainly because of the engineering involved to create an efficient working system)

  • Michael Smith

    The light bulbs were 4 watt. Divide 100 watts by 4 watts = 25 hours for one light or 10 lights for 2.5 hours. Enough for a small house to have lighting at night.

    I am calling BS. Someone in really good shape can output about 200 watts for an hour. That works out to .2kwh of electricity. The average house in America uses about 30khh per day. That is 150 times more than the average healthy person can produce.

    Even if you took a top athlete that can win the Tour de France can output about 400 watts for an hour. Even if you had a house that was 90% more efficient than average that is still .4kwh output versus 3kwh generated. That is still a shortfall of nearly tenfold.

  • David Smith

    While a person might consume 2000 calories a day that is only a distracting figure to the real math. That being said the figure quoted in the video was 1200 watts being produced. At 1200 Watts/sec being produced for an hour that figures out to be 1200 X 60 X 60 4,320,000 watts/hour which sounds a bit high to me. Maybe it is 1200 or 1.2 kwh instead (probably more likely) but still far less than a normal household would use in the USA. Typically around 7.2 kwh/day in the USA for daily consumption. I would suggest that one either have a large family to help out on a daily basis or make plans to spend 6 hours a day peddeling to power a standard home (all electric) in the USA. Still it would be helpful especially if you use a grid tie inverter to dump back on the grid or make plans to buy many batteries to store the energy and use a regular inverter for when you want to run something off the stored power. What a workout that would be, one could expect very strong legs out of this or else very tired legs after such a workout. Much more practical for just lighting and communications rather than powering a whole household ( lighting, cooking, heating, cooling and power tools as well was cleaning tools and hot water). But not to diminish the helpfulness thereof it is practice for the amount of physical energy expended both for health as well as electrical energy. With some modifications it could be very easy to up the output and supplement the power input causing it to be more sustainable thus causing it to have as much higher resultant output in KWH.

  • Mike Lashewitz

    I did that but it does not put out the energy to charge a system 1 hour for 24 hours.

  • Mark V

    I am unsure about that 1050 watt number. The world record amount of energy ever used for an hour on a bike is 430 watts. How could you produce 1050 watts in one hour on a bike machine if the strongest human could only produce 430 watts in 1 hour? This would reduce the number of kWh by over half.

  • Mark V

    It isn’t that he is trying to help, it is that he is so misguided. Kinetic human energy is a terrible source. Why is he promoting something that is a total loser. If he were donating simple solar energy units it would be cheaper and infinitely more effective. At most you would get .2 kWh from the bike in 1 hour of use. Solar in even the coldest poor climates clocks in at over 4 kWh per day per square meter. That is about the same as an hour on the bike for each 1 square meter of solar panel and no one is wasting an hour riding a bike machine. http://solargis.info/doc/_pics/freemaps/1000px/dni/SolarGIS-Solar-map-DNI-World-map-en.png

  • Mark V

    Ken, I agree with what you are saying completely, and you could get enough energy from a bike to generate the little energy needed for a few LED bulbs, a laptop and a cellphone. The problem is, there are infinitely better ways to produce those small amounts of energy than having humans expend the energy on a generator. Look at the bike. The embedded energy cost to it is probably 10x what it would produce in its lifetime. It would be stupid to pay for these bikes in every home in all of the poor communities around the world. Much better to give them wind or solar power.

  • Mark V

    He clearly says in the video, if you pedal the bike for 1 hour you get electricity for 24 hours. This is true as long as you use very little power for the 24 hours. The whole thing reeks of a scam. There are incredible people working on micro-power solutions, and all of them are light years ahead of this guy.

  • Mark V

    And herein lies the implicit scam. As gordon says, you can’t get more energy out than you put in. There are no pulleys, no gears, nothing that can create energy. The maximum output that a human can produce is 430 watts per hour. The average human is WAY below that. This bike doesn’t produce much energy and the fact they never tell you how much energy it produces tells me it is a scam.

    The “calorie” used for human energy intake is actually the kilocalorie. So you’re off by a factor of a thousand. Otoh, the amount of mechanical work produced during an hour workout would probably be closer to 1000 kilocalories for a trained athlete. So multiply your result by 1000 then divide by 2 giving 1 kWh. I guess that’s about an hour of microwaving.

    Actually consumption and output availability aren’t 1:1 and also bicycle cranking uses body weight as much of the driving force, you don’t do much other than shift weight and stand for a moment and repeat.

    Watts are a rate, not an energy quantity. 1200W is 1200 Joules per second. So your number should be 4,320,000 Joules per hour. Or, put another way, 1200W for an hour is 1200Wh, or 1.2kWh. Joules and kWh are both energy units. Be careful to account for the multiplication of time versus the division of it. Power times time equals energy. Energy divided by time equals power.

Which you aren’t)…Somehow, it seems like a day’s-worth of calories could be put to better use.

  • David Asher

    When defining human consumption, calories are denoted with a capital C, meaning that 2000 Calories is actually 2000 kilocalories or 2,000,000 calories. Your math is correct beyond that. Divide the Watt-seconds by 3600 and then by 1000 gives you 2.36 KWH which is a fraction of what it takes to run a modern household.

  • rob johnson

    Consuming calories (biological fuel) is totally unrelated to how many kCal or joules (or watt-seconds, whatever unit you want to use) you can generate with mechanical forces.

    What matters is the efficiency of the conversion equipment and the losses in the transmission and storage

    Also, how do they calculate the energy consumption of a house in 24 hours? There’s a huge variation depending on size and use cases

    Another separate issue is cost benefit analysis. How much does it cost to convert a household to be powered by DC cells that are recharged by flywheel? A damn lot

    Of course people said electric cars would never be cost efficient to be practical, and now they’re pretty common. So I’m not saying this will never be implemented in a practical and scalable manner, but right now it’s a gimmick and clickbait

    Sorry to be “the hater”, but this is a feeble device. The wall of lamps was only a 6 X 4 array of 4 Watt LED lamps. Totalling 96 Watts of required input energy.
    To put some perspective onto this, a cyclist on Tour de France can output power in the range of 200 – 300 Watt. (if sustained for one whole hour = 0.3 kWh = bugger all)
    However the cyclist can benefit from all of their energy input, as the losses are minimal, as opposed to electric conversion..

  • Njimmy

    The point is: Making something spin faster does not introduce more energy into the system. It will most certainly introduce MORE losses into the system. (windage & heat).

    Remember the input energy can’t be increased, we can only take advantage of a whats left after the losses…

    This is an obvious hoax. One person can pedal a 110-volt generator for maybe 30 seconds at a time (I have several 110- and 220-volt generators). You often see pedal machines set up at science fairs running one lightbulb, or maybe a television set. Running a whole household? Stove = 220 (not possible to pedal that amount of power), hot water heater = 220 (not possible to pedal that amount of power), clothes drier = 220 volts (not possible to pedal that amount of power), plus refrigerator, television, lights, furnace fan, computer, and so on. Each ONE of these would require many people pedalling to produce enough continuous power, and that’s ON TOP OF the power you’d need to produce in order to power a battery system.

    There are gyms in Portland, Japan and London using this technology, and the Portland gym is starting to open franchises. The engineering problems seem to be solved for these locations.

    Resource Fitness, the manufacturer, sells its equipment for the same $1,200 price as non-electricity-generating machines, removing the question of how long it will be until the energy savings pay for the cost of the unit. The company can afford to do this because its designs don’t call for the extra wiring needed for battery packs and large converters. It is also trying to price competitively with standard equipment so more gyms β€” and gymgoers β€” will make the switch. ”

    The gym equipment produces twice the amount of electricity needed to run the facility. This has proven to be very economical.

    I don’t know what you calculated there, but the energy turnover for a human is more like 2.000.000 calories, also known as 2000kcal. According to your calculations that’s 2 kwh. All that aside, as a road cyclist I can tell you that a fairly strong cyclist(racer) will be able to do 1kwh of mechanical work in about 4hours, maybe 3h if he`s truly elite. But at a mechanical efficiency of 25% it I doubt it’s worth it, again, being a cyclist, I can also tell you stories about my extraordinary food bill πŸ™

  • zarfmouse

    This is crazy and harmful thinking. Let’s think about some obvious things:

    Really hard exertion burns about 600 dietary calories per hour. That’s about 0.7kWh. But really you only get about 25% efficiency from the human body so assuming a 100% maximally efficient generator bike and battery (both impossible) we get to at best 0.2kWh per hour from a person pedaling a bike really hard. So that’s a maximum of 200 Watt Hours per day for 1 hour of work if the machine is PERFECTLY efficient.

    What can you do with 200 Watt Hours? Well it takes 150 Watt Hours to boil a quart of water. It takes 50 Watt hours to run a single 4 watt LED bulb for the night. Oops now you’re out of power. You know how else rural people can boil a quart of water? By burning about a tenth of a log of firewood.

    These 3 billion people (half the world) who has no or little electricity? Do they have extra food? Are they eating more food than they need, are they overweight? No they aren’t. So if they’re going to burn an extra 600 calories per day, they’re going to have to eat more food. So it’s not free energy. Food costs money. And how about that hour of time? Do these 3 billion people have a lot of leisure time, can they afford to pedal for an hour a day? What are they giving up during that hour?

    “you will never run out of electricity” – Well until you can’t afford to buy the extra food, or until you can’t afford to spend the extra hour pedaling, or until you can’t afford to replace the battery which will probably need to be replaced every 3 years (1000 deep charge/discharge cycles).

    “you will never generate pollution” – You’re telling me that mining the materials for this machine, creating the machine, transporting the machine, and dealing with the tremendous environmental impacts of battery disposal all have no pollution? You’re going to do that 3 billion times and generate no pollution? Fat chance. And then as I said all these 3 billion people are going to need to eat an extra 600 calories per day. Growing and transporting that extra food won’t generate any pollution either huh?

    Most of the cost in this machine is going to be the battery. Why not give the same 3 billion people that same battery with a solar panel attached so they don’t waste an hour a day and 600 calories of food keeping the battery charged? And then the video talks about people in the US stuck in a natural disaster – why not give those people a UPS unit which is just a big battery that they can charge by plugging it into their cheap grid power?

    I read somewhere that this machine is supposed to cost $100. I would believe you could buy this machine for $100 retail in the US or maybe that a factor would charge you $100 to produce it. But how about the costs to deliver the machine to all these ultra rural off the grid places and train the end users how to use it? The logistics on that ought to drive the cost up by quite a lot, this isn’t a light weight or small item. So maybe it’d be $1000 or even $10,000 per ultra rural home once you account for these costs. Where does that money come from and why wouldn’t you spend it on solar or other technologies instead?

    There’s nothing at all revolutionary about this machine! It’s harmful to people and the planet to consider this a viable option. It won’t help with pollution or climate change or global poverty.

    And it won’t even help Americans lose weight. Sure we’ve got lots of excess calories to burn in the developed world and we could use the exercise collectively. But this thing lets us generate 200 Watt Hours per Hour from our body fat. 200 Watt Hours costs about 2.5 cents. Do you think someone who wouldn’t otherwise get on an exercise bike would hear “OH I can exercise for an hour and save 2.5 cents?!” I’m so doing that!

    2.5 cents per hour. That’s what this machine is worth to its users in the US. And meanwhile 600 calories of food will cost anywhere from 12 cents (canola oil) to $9 (turkey cold cuts) or plenty more.

    A bit of perspective, a typical American household uses 30,000 Watt hours per day. This thing generates at most 200 Watt hours per day.

    There Ain’t No Such Thing As A Free Lunch

  • chironfamily3

    I bet they will ban them here in America! I always said this could be done to generate power for batteries in a car!

  • Steve Greenfield

    I call BS. A healthy adult male can do about 100W for one hour, tops. So a 1000W microwave, if the generator, battery, and inverter are 100% efficient (not even close) could run for about 6 minutes and then it is dead. Water heater? No way. Enough to run a few LED bulbs if you are careful about how long you leave them on. Charge a laptop.

    A desktop computer draws a lot more than 100W. A large screen TV will eat through that in a short time.

    So if you are in a cabin in the woods with just one bulb and your laptop, this might be true.

  • Steve Greenfield

    Except that the actual power output that a healthy adult male can sustain for 1 hour is … 100W. So a 100W bulb for one hour. Less, as you point out there is storage inefficiency. Then there is the inefficiency of the generator, and of the inverter.

  • Philtopia

    Sounds great, please post the link to where we can “buy a complete solar water heating system package that generates 3 kW an hr and is 92% efficient.” I’ll do it if it is legit.

  • Njimmy

    Ok Dave. No need to start name calling! I’m only talking about the fact that the increasing the RPM of an internal component does not increase energy output. I and most likely many others are thinking you’re confused.
    It’s ok. But name calling is childish.

  • Rakesh Pandey

    How much does this equipment costs?

  • peterw

    OK fair enough, two things however. 1 the article shows an exercise machine with a large flywheel and a 2kw industrial alternator. The battery system is not referred to but is obviously needed as the headline indicates “1 hour of pedaling for 24 hrs of electricity”. 2 The energy required to turn a 2kw alternator connected to a bank of battery cells for one hour is beyond human capacity. regardless of how much sugar is consumed. The gym equipment you refer to would not be capable of producing that amount of energy individually, maybe 100 peaces in tandem will. Hence to be honest, for this system to work as indicated by the headline, the engineering requirements are going to be very expensive. In any case still not anywhere near as efficient as burning just 1 liter of petrol in a $700 2kw generator unit. Petrol and sugar are actually the same ‘organic’ by products of solar energy. Hence the reason people who spend a lot of time on gym equipment consume a lot of sugary stuff. Actually sugar is more expensive at the food store than petrol per liter!

  • xylene2301

    naaaah…not that much. The price you’ve quoted is full super retail, like if the government was buying this stuff.
    Realistically, the generator and the batteries are the expensive part. Batteries; maybe $500 for a couple of good, deep cycle 24volt. The expensive stuff in the generator are the magnets and the coils. $250 for the magnets and $100 for the wire. The rest could be done with bike parts and some welded steel; $200?
    So a little over $1000.

  • xylene2301

    Yes Len. Exactly right. Wind is trickier and higher maintenance because of the moving parts but due to the present low efficiency of solar cells, wind power is best on days when the sun goes in, ie. stormy weather.

  • xylene2301

    Hydro is great if you have a stream. Not everyone does but almost everyone has wind or sunshine.

  • Sarah H.

    The real issue I have with wind is the massive EMFs it gives off, and also, the avian deaths caused.

  • Njimmy

    Please read up proper thermodynamics, mechanical engineering literature.
    Refrain from watching the perpetual machines on YouTube.
    Resorting to name calling is a childish trait.

    There is no power shortage. Google LFTR.

  • Franklin Bacon

    Where do I get one? What is it called and what company produces them? How much does it cost?

  • btechno

    Well first of all, an average individual consumes about 2000 KILO calories (kcal) per day, not 2000 calories. So your calculation is off by a few orders of magnitude.

    Second, a person would not burn 2000 kcal in an hour of stationary biking (unless, maybe, they were Lance Armstrong). More realistically, an individual would burn somewhere between 500-1000 kcal in an hour workout session.

    Going by the top end of that estimate, a person burning 1000 kcal per hour would generate about 1.16 kilowatt hours of electricity, assuming no energy is lost, which is absolutely not the case. Still much much higher than your estimate.

  • Wombat

    “The real issue I have with wind is the massive EMFs”
    Can you explain please?

  • Any plans as to how to build one?

  • ScoBot

    OK. Where do I get one? Are there programs to subsidize the purchase? I mean, this is interesting and all, but where’s MINE !??!

  • Eric Van Bezooijen

    For probably a similar, or lower, cost compared to this generator bike you can get a solar panel, a few batteries, some LED bulbs, and some logic circuitry and have solar powered lighting all night and all day long. You can then go work at at a job instead of having to bike for 8 hours every day generating 75 watts, which is the amount a normal adult can sustain.

  • Cole Panike

    Yup, you’re right. Certified BS.

    According to Wikipedia (which has a good citation):

    “A trained cyclist can produce about 400 watts of mechanical power for an hour or more, but adults of good average fitness average between 50 and 150 watts for an hour of vigorous exercise. “https://en.wikipedia.org/wiki/Human_power#cite_note-2

    That means in a perfectly (100%) efficient power harvesting system that a human produces 0.1 kWh (in an hour). An average american household consumes 30 kWh a day. (http://tinyurl.com/hzu5dfj)
