Our area does. It doesn't work quite as well as salt, but it isn't an environmental nightmare, either.

Remember the problem with the water in Flint? This was primarily due to their using salt on the roads, which washed off into streams, which in turn fed rivers - and Flint was getting their drinking water from these rivers.

The corrosive effect of the salty water was so bad that a local General Motors plant had to stop using it to wash their engine parts, because it was corroding the parts. So, imagine drinking that water.

Also, because it was so corrosive, it dissolved the lead in the pipes, which was the main reason it was such a disaster.

Exactly. I'm an engineer, so I asked it to calculate the loading on a beam. The first attempt returned 35 grams, which is 4 orders of magnitude too small. The second attempt returned 800 kg, which is more plausible, but I'd have to do my own calcs to verify it.

There is another aspect of using hydrogen as a fuel for ICE vehicles is rarely discussed. We hear that the exhaust is just water vapor, but this isn't always the case. The combustion temperature is so high that nitrogen from the atmosphere (which is always part of the intake mixture) is converted to nitrous oxides, which are expelled during the exhaust phase of the cycle (nitrous oxides are also produced in regular ICEs). This is an undesirable pollutant.

On a related, and very disturbing note, "Slavery by another name" (https://www.youtube.com/watch?v=UcCxsLDma2o) describes peonage, the exception to the 13th Amendment ending slavery, that allowed involuntary servitude to continue for convicts. The problem with this is that police arrested black men on trumped up, or outright false, charges; corrupt judges signed off on these arrests; prison "sold" this free labor to farmers.

Watch the video - peonage was never taught in school, and definitely should have been.
