Heavyside invented vectors. Each Maxwell Equation in vector notation is 3 equations the way Maxwell originally did it. Heavyside gets some credit for inventing vectors, but not all, because Gibbs (an American) invented them, independently, about the same time. Heavyside was a recluse and...

Yeah we’re running out of gasoline and diesel and, yeah, we’re converting more and more of our food into fuel, but the real problem is shortage of water. Turning corn into gasohol will raise corn prices which will make more farmers plant corn. There are lots of farmers and lots of land...

It's done with a type of recifier (in receivers is called the detector)

I'm wondering if you counted the magnetic field contribution from the wires that supply current to you loop.

A friend of my used to talk about a liquid core reactor that he’d worked on. The fuel was in a uranium solution and circulated through the critical-reactivity region, the primary heat exchanger and through a filter that removed the spend Cs, and Sr. The Cs and Sr stayed in the reaction vessel...

Doesn't liqiuid sodium alloy with the metal in piping?

I saw the demonstration years ago. Now that you mention it, I believe he had doped the flame with salt or something.

I remember a demonstration with a tall gas flame that had two electrodes, one near the top, the other near the burner. The electrodes were excited with the output of a audio amplifier which had been passed through a transformer so that its voltage was on the order of 1000 volts (maybe more)...

They used a carbide bicycle lamp for the experiments. They sometimes used a sodium-vapor lamp to help set up.

You put electrodes in the water between the magnet poles. The electrodes have to be perpendicular to the wate flow. I believe and old microwave oven magnet would work. You may have to put salt in the water to get enought current. I believe on the order of an amp

The ripple frequency is higher (360Hz) and I believe those X-ray tubes produce X-rays only at the peak sof the ripple waveform. So you'll get 3-times as much X-rays.

You could put a 6 volt battery in series, but put it in backward,i.e.,+ to + and - to -

There are 3-PHASE induction motors. I never heard of a magnet with 3 poles

3-pole? A magnet as 2 poles, so a 2-pole motor is like a magnet spinning on a shaft perpendicular to the poles. A 4-pole motor is like 2 magnets

You can sense (or measure) the magnetic field by holding a compass near your rotating, charged hoop. But, if you mount the compass on the moving hoop, the dipoles of the compass needle will be moving and generate an electric field that interacts with the electric field of the hoop. This...
