I think meteoric activity is in there as well sice it is the "doping" of the photosphere that makes a difference. Plasmas emit photons roughly proportional to the square of the number of electrons of the atom making up the plasma. Iron has 55 so it has much more emission than hydrogen with 1. S

A fuel cell is a "battery". Where lead acid batteries require electricity to charge them, fuel cells require a fuel to "charge" them. Now, let's say you have 100 kWh of electric from a generator, and you charge a battery bank, that is more efficient than taking the same 100 kWh, electrolysing w
