We know a thermoelectric generator produces electricity from temperature differences, and we know the earth is warm compared to outer space – does that mean we have a vast, untapped energy source? Physicists at the Harvard School of Engineering and Applied Sciences (SEAS) think so, and have proposed two different ways we could generate DC power by emitting infrared light into … [Read more...]
