<p>[QUOTE="-jeffB, post: 7620800, member: 27832"]I've seen references to those before. I'm still pretty skeptical. To generate power from a thermal difference, you need a warm side, and radiating into a cold sky cools things off very quickly. Thermal generation is also inherently inefficient. It's better than just letting the energy radiate off into space <i>without</i> trying to catch it, but it would be awfully expensive per unit of energy captured.[/QUOTE]</p><p><br /></p>
