I know this is an old video but I am really interested in making one of these. Makes sense that if you're going to use a stationary bike to workout anyway, then why not also use it to help reduce your electric bill.
So , tell me if I have this right please..you plug your bike into a power outlet, and switch on the electric motor,
the pedals start to turn, pulling your legs along for the no effort ride. If you pedal hard, you can overspeed the motor
and for a short time making only a very small amount of wattage and likely less that the machine is using while it runs....so where is the plus amount of power?
A motor and a generator are one and the same, it depends if mechanical power is being put into the generator or taken from the motor. A person can continuously put out about 75W of power into the grid, 10 times more than the bike uses for electronics.
Nice hack, could've used this last night when PG&E went out for the second time in a week! Does the Kill-A-Watt accumulate a KWH number for the entire work-out?
May I ask why you put black vinyl electrical tape over the logos above the LCD on the P3 P4400 Kill-A-Watt meter? Are you ashamed to be using one? BTW I think your machine is great but I want to point out that you don't need a grid tied inverter to pedal and send power back to the grid as any standard small induction motor will work also. The only downside is that since the motor runs at a constant speed (+/- 10%) you need variable gearing if you want to pedal faster or slower.
That's fantastic. I do an hour on my exercise bike a night, and always thought how great it could be if my energy could be converted into power and pushed back on the grid. I joked about it with my wife, but never thought it was really doable. It would be great if you built a site detailing the parts needed there, or how one could retro-fit a standard exercise bike to generate power and feed it back onto the grid. Imagine if gyms hooked up their dozens of exercise bikes to the grid. :)
great great great... Can you please tell me how much did that small grid-tie invertor cost ?? I can't find a small one on the internet, I hope you can help me !
Now this is a hell of a lot more interesting than Britney Spears on stretcher. If the viewer count was reversed I'd almost believe there was hope for this planet!
PS -- Where the *&%@ can I find a Grid connect inverter that won't put me out 2 grand?
They could probably be manufactured for less than a $30 Walmart DVD player, but again our priorities are #*%$ed.
Meanwhile, my wife is using a treadmill that DRAWS 1500Watts! $#!^ ME SIDEWAYS!!!
Brian, thanks for your entry. I'm really glad to see that someone has finally created an electric generator that doesn't waste all the extra energy put into the system. While you'll only be saving quarters a year, it's the awareness that you can bring to friends and family about the importance of conserving energy.

So do you have to overspeed the motor to produce power? or does the motor not spin on its own?

i KNOW IT WORKS
Good job
Keep up the good work
Get a gum to set this up !
Run a gen using free vegi oil
or wind
Solar works also

I think this is a fake...the machine pedals him not him pedaling
the machine...it's a scam.

The motor sets the speed of the unit, it is up to the user to over-speed the unit and turn the motor into a generator and send power into the grid.

you're using more than you make.
why have a motor and not just a generator?
ANS. it's too hard!

What if you connect an eletric motor to spin the power generator that is powering the electric motor?

need to pedal megga to get anywhere as the average human can only generate about 100w of power

wrong! too bad you don't know what you're talking about.
My machine can steadily deliver 250 -270 watts
while I pedal at 60 rpm and with only a medium amount of
"Push"

Fantastic! How can the world be suffering so badly with brilliant minds like yours around. Great stuff mate, and all the best for the competition.
