comment How do solar panels generate infinite electricity?
I don't think you'll get 1300 W/m2 on Earth - only at the edge of the Earth's atmosphere. Peak sun at the surface is usually taken to be 1000 W/m2

comment How do solar panels generate infinite electricity?
@Bhavesh we don't know how long monocrystalline silicon cells can last - we've only had them for a few decades. We know that at the end of one module's life you can strip off the old encapsulant and re-encapsualate the cell into a new module. But the economics don't really make this very worthwhile.

comment How big is the power loss of a downwind wind turbine due to turbulence created by an upwind turbine?
The only rule of thumb I know of is: 5-7 blade diameters between turbines. But that's grid-scale, not home wind turbines. Are these roof or pole-mounted? If the latter, how high above the roofline & treeline? If the former, then they'll be pretty ineffectual whatever the spacing.

Indium isn't a rare earth element though, is it?

comment Temperature to make oceans evaporate
Do you want to know the temperature to make seawater evaporate, or to boil? They're different things.
