Geothermal energy will get the U.S. off our crude oil addiction. Iceland is proving geothermal energy works. Pro's and Con's. Your thoughts.
How do you get this geothermal energy in a car/truck/boat/whatever? I agree with what you're saying, but Iceland is tiny compared to the US. I say nuclear energy would be the best overall, even with the negative possibilities. Where is the Stanley Steamer when you really need it?

I disagree w/ nuclear. Geothermal is more abundant than nuclear, which means geothermal is better on the wallet. How to get it in your car/truck/boat/whatever? How do the Icelandians do it?

I'm all for creative ways to produce energy, but here is a "con" concerning Iceland's usage of the energy source:
"Iceland's geothermal power stations are worth a look, even though geothermal energy is a far from trouble-free source of power. The geothermal generators are built in areas where earthquakes are likely, and the steam is generally contaminated with minerals leached from the rock, which damage tubes and turbines. So they are not the principal power source for the island."
Geo-thermal does have some heating and electricity producing applications.
As for the case of completely replacing all petro use with geo-therm only -- that has some problems -- think of aircraft, for example.
But anything you can use to produce electricity can cover most of the rest of energy use -- lighting, A/C, heating, industrial and commercial applications, ground transportation -- those add up to most of our energy use.
Geo-therm produces electricity fairly well. The mineral clogging can resolved by heat exchangers. Downside is the easy sites to use are relatively few and far between. A current proposed method is (very) deep bore holes, but those are not cheap. Solar thermal is about the cheapest, and produces very easily during the day -- when most electricity is used.
But all of this is more of a money issue than a method issue. Presently the price to beat is coal fired electrical generation. (yeah, I know -- CO2, mercury, mining, radiation, and ash waste problems -- just talking price). Solar thermal is the only thing that I have found that can beat coal on price. Wind, maybe, but only maybe.
At first glance, Solar PV is about the most expensive, but in truth, Nukes are about the most expensive once you consider proper waste disposal.

You get it into your (electric) car as electricity generated from the geothermal plant.
