"You may now proceed to call me an idiot for saying something positive about Ubuntu."

It won't be me, I use Mint, Ubuntu in green. No driver problems, but an occasional problem with getting second hard drives mounted. Fstab is a bit picky, here you must use a space, there you must have commas.

The most annoying problem I've had is a multiple file copy to a Mac reliably fails, every other file gets truncated. This happens with Nemo and Thunar, but doesn't seem to happen with Caja. Yes, I've set up machines with all three to play around.

In the course of all this I think I may prefer Mate. (gasp!)

Observation: open at the desktop ready to start something Cinnamon uses 1.8 GB of RAM, Mate 1.3 GB, Xfce 1.1 GB. MacOS 14.4 is at 1.9 GB app memory, 1.1 GB wired memory, so 3 total.

Drag races are irrelevant to the statement. As I said, pulling the boat out of the lake is not a problem. Pulling the camper up the hill on I-80 east of Pendleton OR is the problem. Or worse, heading into the mountains pulling the trailer on a curvy dirt road? At low RPM you will need high current, how long until the motors overheat?

As to the other issue, so I might have an issue charging at Grangeville ID the driving down WhiteBird hill. As long as the normal brakes are still adequate to the task no problem.

Firearms can not be bought online legally. You can pay for it online and have it shipped to a local FFL dealer, and that dealer will then do the background check and all the required paperwork.

Some states do allow you to buy alcohol online. I've never done that so you'll have to find a place and read the FAQ.

In a EV car you can get away without a transmission. In a truck I have my doubts. Getting torque at low speed requires high currents. That will heat the motor windings quickly, I-squared R losses are a bitch. A locked motor burns up quick. That's why they have thermal overloads.

Industrial Variable Frequency Drives have a variety of settings to use to get more torque at low rpm without burning up the motor. But the ability to do this is limited. It works for starting conveyor belts or for pulling a boat out of the water but not for much longer.

Although the automatic in my 2020 truck is much better than the one one in the 2008, (that one went spastic on any reasonably steep hill) it still tends to to be in the wrong gear quite often. Last summer I had to take manual control bringing the camper down the steep dirt road as the transmission left to itself would have had me running about 60 mph when 15 to 20 was the correct value. Riding the brakes that long is never a good idea.

Question for an EV owner, on a long downhill do you lose regenerative braking when the battery is fully charged?

Methanol fuel cells already exist. And of course it does burn too, you could use it fuel a combined cycle gas turbine generator too.

And you can Fischer-Tropsch methanol into anything you want.

How long does the catalyst stay clean and how hard is it to regenerate are the next questions.
