Tapping the Earth For Home Heating and Cooling
suraj.sun recommends a CNet post giving details of a still little-known energy technology: the ground source heat pump or geo-exchange system. This is distinct from so-called geothermal energy, which taps the heat in the earth to provide energy. Geo-exchange is suitable in scale for small industry — the article describes one commercial re-development of an old mill into apartment and commercial space that put in a geo-exchange at about half the cost of traditional fossil fuel-based alternatives. Even some individual homeowners are opting for this green method of heating and cooling, at a premium in price of about 50 percent (but costs are very much per-project, largely because drilling is involved). "Rather than use underground heat, geothermal heat pumps attached to buildings capitalize on the steady temperature of the ground or deep water wells. In effect, they treat the Earth like a giant energy savings bank, depositing or withdrawing heat depending on the time of year. "
Am I the only one who read that as 200 milliamp? For a moment I was astounded by the home's efficiency.
Let us not become the evil that we deplore.
Just think of it as mother earth.
200 milli-Angstroms? That's a damn tiny house...
Cantankerous old coot since 1957.
Wouldn't you substitute du for dx and then antidifferentiate? Or do I just have calculus on the brain?
...I would also point out that Bush's Crawford Ranch [snopes.com] uses a geothermal heat pump.
Ah yes ... but does Al Gore's?
The higher the technology, the sharper that two-edged sword.
...in Utah uses GSHP for almost every school. It saves them a grundel, but takes years to pay off.
What is a grundel, and why would you want to save it?

Ya, its pretty common here too.

I tried to stop by his place, but since I knew its momentum exactly I couldn't find it.

Al Gore doesn't have a Crawford Ranch.

This is why you should leave it to the professionals. I bet you just went ahead and arrogantly acted like an expert without even buying a proper pair of tap shoes.
The dragon also keeps the kids away from the GSHP equipment which is near the playground.
