It is interesting to note that whenever a discussion of electric cars comes up, the proponents always dodge the issue of already maxed out grids. I have yet to have seen a plausible response to this key issue, if any response. I guess there will be more electricity available by magic

And now that we have completely hijacked the OP's thread, let's get back to recovery machines.

I have been through a couple of portable recovery units in my time working on stuff. Generally a 3/4 or 1 hp portable - because lugging anything else up on the roof is not going to happen.

I started with a used portable recovery that I got for free with a "bad motor" Fixed the start switch and used it for years.

All you need is a recovery machine and some tanks. The tanks are not expensive. I have recovered R12, R22, R500, and R134 through the same pump.

Keep a "junk" tank. If you are not sure about the system? Yeah. Want to flush your recovery unit? Hook up the junk tank and send some R600 through the pump.

The grid issue needs to be solved for sure. IMO nuclear is the way to go.

With regard to EVs, all Tesla Superchargers are being converted to solar/battery power. Over time, almost all will disconnect from the electric grid.

So, every 250 kw supercharger will need a massive battery, and a 750 kw solar array ? So about 6,000 square meters of silicon? A couple of tons of lithium batteries?

Comedy gold.

They laughed at the gasoline engine too.

I see electric cars in our future. Learn to enjoy the future as it comes.

{shrug} Many supercharger stations are already self-sufficient.

I forget where it was, but I remember reading about a power outage in a city somewhere a few months ago and the only thing anywhere that was brightly lit and working was the Tesla supercharger station.

Gasoline engines are ridiculous. They scare the bejeezus out of the horses.

Show me. Post the links not the lore.
