Yes. I didn’t want to get into “there is no such thing as a vacuum” because of quantum. While true it probably doesn’t affect dielectric constants.

Salt lowers the freezing point of water. This causes some of the ice to melt. The melting requires heat energy and this makes the solution drop in temperature.

Take two bowls and put an ice cube in each. Add salt to one. Watch.

Edit cure to cube

In this case the colder ice water and the 32/0 degree ice water have the same amount of heat present.

They started in a cooler and the addition of salt made the change in temp happen relatively quickly. It’s colder as the melting ice takes heat energy from the water, cooling the water.

The cooler will have cold on one side and ambient on the other. The colder it is inside the more heat transfer through the walls.

I’m guessing that this is their perception only. It would be an interesting test.

I see what you did there. Very clever.

I get your point. That was a single piece of equipment in a massive plant. The utilities had no problem supplying us.

Having charging stations use the power of a small town is actually not that big of a deal right now. Having many of them in 13 years is not that big of a deal.

I was mostly just curious so I did some quick math. There seem to be some pretty knowledgeable folks here. If I get something wrong, just tell me and I’ll correct. 2500hp X 0.746kw/hp X 24hr X 365 =16 million kwhr. An average house is about 10,000 kwhr per year. That motor was worth 1600 houses.

We had a separate building for the variable frequency drive. We weren’t allowed to start it across the line. It would have browned out the city.

Can confirm. I worked at a chemical plant. We had a 2500 hp motor. It used more electricity than a small town. The power company had conditions for turning it on, but they were more than happy to supply us with, and charge us for, power.

Edit; hour to hp
