Pedal bike 12 volt power generator, dirt cheap, ghetto style

@awizardalso I did somthing similar with a exercise bike that had a 35amp alternator and some resistors to make the load. I unpluged the load resistors used it as a 12volt generator. I couldn't run a 100 watt halogen head lamp for very long! Under a minute! Just to hard! 7 amps on the meter at 14.6 volts. If your pritty fit you might do 75watts continuously. It's easy till you get over 3 amps. About 44 watts.

utuberifyer-- I built one years ago using the old (external regulator) type alternator that had the independent field coil. Seemed like an extraordinary amount of work for the amount of power produced. I think pedal power is best suited for a drive system for short term use of a machine, like my sewing machine, or maybe a water well pump, corn sheller, bread dough machine, etc. Generating electricity just doesn't seem to be very practical.

Are you putting a blocking diode on this set-up so your not fighting with the motor?

Great vid
So every gym in the world COULD be using this technology but we are paying more for electricity and gym memberships than ever before???....

Nifty!

Can this same technology be applied to a standard car on all four wheels.

If so how can one capture and store this energy in batteries.

if i did that (and being lazy i wouldn't) i would put the front wheel to the wall in case of a catastophic but potentially funny accident!

My legs hurt just watching that.

Awesome

thanks ! very instereting
