Response to Geothermal engine
<t>Huh, I didn't think of that, but that sounds pretty sweet. It makes a lot of sense, all the constancy of a cave and it's massive volume without the cave bit. The earth as a cold sink, as in the reverse of a heat sink.<br/> <br/> Well that's good to know, but you probably don't want to embark on t...

Response to Geothermal engine
<t>Unfortunately I don't think that would work. Because all mechanical engines are inherently inefficient it would probably suck more heat out of the house than it would generate electricity; H lost > E gained. You could however run one in reverse and use it as a heater, though I don't think that's ...

Response to Geothermal engine
<t>Well I'm back with about 5 years of additional education under my belt and I can now say with confidence that this should potentially work. I've got bigger plans now, but this is a nice reminder of where I started on the entire alt energy thing.<br/> <br/> The real trick is to get really rugged S...

Geothermal engine
<t>There is a reasonable amount of talk about turbines run off of <br/> geothermal energy. Would using a Stirling type engine be more <br/> efficient? I know it is really of vague. Can someone expand more and <br/> explain to me how geothermal turbines work, or is it just the <br/> expanding hot air...
