Very good article. Covers many points of information with limited words.

One I noticed is that TEC has already been generally dismissed. They didn't call it by name, but the description fit. And the problem described is the very one I was mentally wondering about whenever I read any articles on the topic.

But for this method, I have a similar problem. They say that heat detected by satellites (likely referring to 'outgoing long wave infrared') is caused by the neutralization of the ions from underground.

Here's some of my rambling thoughts...

It would take a lot of ions to heat the air enough to be noticeable by the satellites. The GOES sats are not high resolution (about 1km IIRC, I look at the images every day). How much energy does it take to heat one cubic kilometer of air one degree?

And all that energy is coming out of the ground in the form of released ions?

And no on the ground has ever noticed this?

And since this wind blows, it takes more ions being released to heat the air before the ions are dissipated by the wind.

Further, by the time the ions come from deep underground some of them are surely to have been absorbed on the way (losses), which means even more of them are generated underground.

And, ions are generated by voltages, not currents. You can have 1 million amps, but if it's at 1 volt, it ain't gonna do jack. On the other hand, 1 million volts at 1 millionth of an amp will generate tons of ions. Basic electrical engineering, which is something I did study when I was in electronics school. That's why Tesla coils are high voltage, not high current.

Current flow is what generates a magnetic field.

However, you can have both together - high voltage and current. You usually need higher voltages to get current to flow through a resistive medium. Basic Ohm's law. And I'm sure rocks are 'high' resistance. But, that brine mentioned is low resistance. THAT's why they don't measure any voltage in compressed rocks. The brine shorts it out.

I dunno...just rambling thoughts. And many questions.

Need to read up on telluric currents...
