I'm not sure about the "anywhere in the world" part,...

Try reading the entire article. He really is talking about "anywhere in the world."

Don't want to inject fluids under pressure near earthquake zones:

Actually, one of the long term proposals for protecting against damage from earthquakes, is to inject fluids into faults, lubricating them, and causing hundreds (or even thousands) of microquakes, to replace the small numbers of large destructive ones.

Correct. 2 percent. I deal in these damned digits all day and get digititus.

Yes, a good idea in principle, but who would be willing to host the Insurance Liability?

True, fluids can have that effect. But at what point do you stop? Too much and you have more than just micro earthquakes. Don't think I'd want to be held responsible if the BIG one if it happened while I was trying to lubricate to prevent it.

"Not really. Consider: Coso Geothermal, near Mammoth, Imperial Valley, Steamboat, Nevada."

Yes, really. Compared to the widespread urban power needs for the United States there are damned few geothermal sites sited so they can be tied into the grid so as to get the power to them. (there "is" a limit to how far power can be transmitted, y'know).

He completely ignores the problems associated with its extraction, which have not been solved. I have lived all my life in the area close to the guysers, and the production has been scaled back dramatically since the trial began 30-40 years ago.

Actually, this is indicative of a common mistake that people make when projecting the effectiveness of technology. The early geothermal power plants had the problem that you describe, now they recirculate the water and gasses, and extract energy at the same rate that it is replenished.

There is a geothermal power plant near my house, which just sits there looking like it is doing nothing, requires a very small maintenance staff, and puts out about 50 megawatts.

As technology progresses, the technology described by the author, will very likely become practical.

That said, we already have the ability to build much better nuclear reactors than those that now produce power:

Smart people want to move forward with everything that makes sense. If we had listened to the do nothing, nay sayer, panic crowd, we wouldn't have automobiles, aircraft, plentiful food, and much longer lives than our ancestors.

You've probably heard the old saying, "Those who can't do, teach." I would like to suggest a corollary, "Those who can't do, should just shut the hell up, and let the doers take care of it."

But the "universal geothermal energy" proposed here is sheer crackpottery.

The idea the men might someday fly is "sheer crackpottery."

You are clearly not an engineer.

When gravity assembled the earth from stone and iron, the gravitational potential energy of the uniting parts was converted into heat, and the top rock layers keep this fossil heat contained. Furthermore long lived radioisotopes contribute.

How about if we inject our excess radionucleides into the downstream well? Then it could be both inexhaustible and renewable!

They are much more valuable when used as fuel for Integrated Fast Reactors. Follow the link in post #68.

Don't worry, YOU won't be.

When (if) this technology is developed, it will be tested in less vulnerable areas.

How many wells or feet of trench did they put in for the MN system ? Bet its not in Duluth. That rock is hard stuff.

Yes, really. Compared to the widespread urban power needs for the United States

In your original post you used the term "exceedingly rare" now you are comparing to the total energy needs of the USA. Let's look at the numbers and some facts:

Hawaii -- 30% of the power on the Big Island comes from Geothermal
Mammoth Navy I -- Produces enough electricity for 40,000 homes.
Mammoth/Coso Junction -- 273 MW capacity
Geysers -- Supplied enough for electricity 1.8 million people
Imperial Valley -- 327 MW total at 10 plants
Steamboat, Nevada -- 40 MW at Three Plants
Utah -- 23 MW

Yes compared to the entire USA those are small numbers, but exceedingly rare as originally stated is factually incorrect and misleading. Source: Geothermal Power Plants in the USA

I knew a guy that worked for specialty pump mfg at one point. They'd ship a ceramic lined, ceramic impeller pump
with a warning in big friendly letters to open up the pump casing after it's hooked up, but before it's run for the
first time. Otherwise, more often than not, the motor's power was wired backwards, and the impeller would unscrew
itself, destroying it and the lining.

Never thought to ask him about any geothermal installations.

i once worked as the newbie in a shop and watched the senior maintenance associate throw away a perfectly good expensive electric motor because it growled when he applied test power. #-phase motors do that if the lines are hooked up wrong. When the second motor acted the same way,he decided to check the wiring instructions.

I have several other stories of experienced workers who took over because the newbie was too slow and cautious;they promptly destroyed the item being worked on!

RTFM !

"You are clearly not an engineer."

Nope. Just a PhD Analytical Chemist with Nuclear minor. I occasionally make noises like an engineer, though, sufficient to have 24 issued patents, with more coming, and two R&D 100 awards.

And I say again, "universal geothermal energy" is sheer crackpottery. Having to drill 4 kilometers down to get to a temp of the boiling point of water (not a very efficient thermal differential) is NOT practical, and unlikely to ever BE practical.

In my book, those "small numbers" qualify as exceedingly rare. What perspective did you THINK I had, other than relative to the entire USA??
