How did they do that? The deepest well we ever drilled in the history of the world does not even gd deep enough to get 10% close to the center.

about 19 terawatts can be attributed to radioactivity.

Now the anti-nuke extremists will be forced to boycott the entire planet.

Hmmm.

Not such a bad idea, after all...

The article makes it clear that there is no need to dig down near the core. The antineutrinos pass through everything.

Neutrinos aren't much interested in 10% or 90% or 100% solid lead. If physics, especially particle physics were easy to do it then everyone would and you could be a pundit.

currents that churn liquid iron in the outer core, giving rise to Earth's magnetic field

That is only a surmise. Maybe a hypothesis. Not at all certain. Probably not at all close to reality.

Well, I was ready to believe it!

Somebody asked a famous physicist maybe 100 years ago what caused the earth's mag field, and he said the iron core could be doing it, and that was that. Nobody has questioned it since, except right here.

The earth is radioactive?

WE'RE ALL GONNA DIE!!!

The neutrino and its friends

Neutrinos are one of the fundamental particles which make up the universe. They are also one of the least understood.

Neutrinos are similar to the more familiar electron, with one crucial difference: neutrinos do not carry electric charge. Because neutrinos are electrically neutral, they are not affected by the electromagnetic forces which act on electrons.

Neutrinos are affected only by a "weak" sub-atomic force of much shorter range than electromagnetism, and are therefore able to pass through great distances in matter without being affected by it. If neutrinos have mass, they also interact gravitationally with other massive particles, but gravity is by far the weakest of the four known forces.

Three types of neutrinos are known; there is strong evidence that no additional neutrinos exist, unless their properties are unexpectedly very different from the known types. Each type or "flavor" of neutrino is related to a charged particle (which gives the corresponding neutrino its name).

Hence, the "electron neutrino" is associated with the electron, and two other neutrinos are associated with heavier versions of the electron called the muon and the tau (elementary particles are frequently labelled with Greek letters, to confuse the layman).

Just think about all the platinoids in iron core. More than enough to pay off the national debt and go to sound species money.

"No waste, no fuel, just free heat."

What do you mean by free heat? Nothing is Free. We get our water from "free rain" do you get water at your house for free.

As a practical matter, how would the heat at extreme depth be used to generate power? If it is hot enough to compete with natural gas turbines or nuclear plants, it would be hot enough to do serious damage to equipment, and maintenance to equipment at that depth would not be cheap.

There are also questions of heat production. Heat would be drawn off and the natural processes of replacing that heat would be slow, possibly too slow for economic operation.

Geothermal's been around for awhile now. The heat's free, but converting it to electricity turns out not to be. It's the old "the more efficient the system, the higher the cost" thing that only new technology can really address. When the conversion and transmission technologies improve there's no real reason geothermal can't be quite competitive with surface sources - at the moment it's only competitive in areas where you don't have to go too deep for the heat.

Your ability to cut and paste or forward e-mail is no indication of much of any thing. Yawn. See my tagline.

So, miners actually help in cooling the Earth? Why are the environmentalists against miners and oil drilling? Aren't they supposed to be against global warming? ;)
