How many acres of solar collector would your car have to haul around to
get enough energy? I assume this works by "catching" some of the energy as
it is transferred from the hot side to the cold side, similar to a
thermocouple. So, since energy is transferred from the hot side to the
cold side, the insulated cold side would soon be at the same temperature
as the hot side.
