This whole thing is dumb. why would you go through all that trouble just to make a light bulb glow? lol lmfao There is no use for this thing.

@11secondeclipse The mindset is to get kids and adults interested in alternative energy. When you have kids at a large event and you need something simple to teach them about alternative energy then this is pretty good solution.  Also since this is DC power, it can be connected to a lead acid 12 Volt battery to store your energy.

how can you get all this for a little bit cheaper?

[bicyclegenerator]

@BigPimpB1 You can get a bicycle trainer stand from a 2nd hand store for around $20.00. Also you can find one on craigslist by typing in the search phrase "trainer" . For the generator part, you can buy a DC permanent magnet DC scooter motor from craigslist or Ebay ~$40. You will have to remove the gear on the shaft and fit it with a roller or pulley to make it work. Lastly, you can make your own adapter plate using free plans from pedal power generator d o t com

Ok so how do you get it to where you do not have to pedal so hard?

What about storing the energy and keeping the light bright?

Where do you learn these kinds of things?

[bicyclegenerator]

@adolescent900 If you put a 12 Volt Powerpack like the one made by Black & Decker, or Duracell, it will you store your energy.

You need a bike with a shifter

@pixar5 AC motors run fine on DC voltage.  The generator in the video is DC output.

@web1bastler The permanent magnet generator we use is DC - I can send you the waveforms if you want to see them.

when you put the socket on the cables whitout an diode you wil get AC i a sinewave and not DC!
