Episode 8 - Green Power [Discussion]

[daikun]

The environmentally friendly Joe Geniuses in this episode sure know how to go green! They build emission-free vehicles to get around town, design homemade wind turbines, and use pedal generators to power some of life's amenities.

Minor nit pick here. Joe mentions that the sun is a fusion reactor that is over one million miles long, and that "these Joe Geniuses are harnessing all this power..."

The Earth gets less than 1% of the energy from the sun, and photovoltaic cells have a 45% efficiency at best (commercially available stuff is closer to 6-10%).

So that means these Joe Geniuses are actually getting all the power for their cars by harnessing a fraction of a fraction of the power produced by the sun. Far, far more impressive.

Also, light doesn't contain energy, it is energy.

I know the guy who built the Pyramid Car, and I don't know if you're giving it too much credit but it is basically a golf cart with a couple solar panels and a fancy body on top of it.
