PV Gap

Is this a good idea?

We Answered:

As to the second--you have to have a positive balance of energy to run any device--a heater powered by cold can't work.

But your first idea is a good one--in fact powering home air conditioners with electricity from solar power arrays is one of the main uses of solar technology.

Doing it for a car might work. A car is too small to carry the solar panels needed to power the car entirely--but it might be possible to power an AC unit with a solar panel built into the roof. At the least, it would help the gas mileage in the summer.
