Cheap, pollution-free energy could, in theory, reset the clock on global warming

I hope not. We're in an interglacial period. If it stops being warm, we'll be on our way to being buried under a mile thick ice again.

Don’t worry, we can use ecats to bore holes through the ice.

Besides, ice is fresh water — lotsa problems solved right there. And it makes a good refridgerator.
