So what is so "innovative" about that human-powered gadget?
To be sure, I think it is great that Mr. Bhargava is spending his millions on such worthy causes to improve life on the planet.
Kudos to him. He is in the 1% of the 1% for philanthropy, IMHO.
But the gadget shown in the video looked like nothing more than a flywheel attached to an industrial-strength alternator.
And it looked like there were 8 wires coming out of the alternator in two phases,
And connected to two rather modest bridge rectifiers bolted to the frame (@1:34)
The meters showed ~12V @ ~10A = 120W (@0:32)
Although the dialog (@ 1:55) said "we're able to power 1050 equivalent watts of lighting..."
Perhaps by using more efficient CFL or LED, they are citing the "equivalent" of what traditional incandescent lamps would produce?
At 2:09 there is a close-up of the bulbs on the wall, and the nomenclature around the base says "12V" although they looked incandescent.
The whole video was about the stationary bicycle-alternator, which doesn't look particularly "innovative" to me.
Or am I missing something here? No mention of the storage necessary for practical use.
Big capacity cells would probably be MUCH more expensive than a pedal-powered alternator.
