This morning Fiat announced the arrival of the new Jeep Wrangler Model 4xe......hybrid with two electric motors.

on the battery topic, RTG or radioisotope thermoelectric generators were not converting the radiation directly into electricity. they used thermocouples and solid state peltier junctions to convert the thermal energy that high energy isotopes of plutonium, strontium and others to electricity. the isotope is a way to make a block that stays hot for a long period of time. The new "batteries" use the radiation directly and thus are less dangerous and more efficient. they are using isotopes with much longer half lives, which means they decay and a much slower rate and give off much less radiation.

an RTG can contain a massive amount of radioactive material with a low half life / very high radiation output. SR-90 has a half life of around 30 years if memory serves. many many of these devices left to decay in Russia powering old lighthouses and things. also used to power space probes, like the voyager probes, Cassini and the latest mars rover.

Thanks for clarifying that. It is two different technologies for different applications. The US uses Plutonium-238 (not suitable for weapons like Pu-239) for it's deep space RTGs. Sr-90 has been used for some terrestrial RTG applications. The Russians used quite a few of them for remote sites. In some cases, they lost track of them and they led to overexposures of people who did understand what they were dealing with when the found them.

2022 Subaru is to be an ev player. It is like the 4 minute mile someone had to show the others how to do it.

Non of the Japanese brands have so fare been impressive, Nissan started good with leaf but Nissan showed very little interest in trying to answering the competition, Mazda and Honda have so fare started to sell small cars with very short range, Toyota has showed very little interest in EV, but have started to talk in big words on all they will have soon.... Even hybrids with charging have Toyota resisted until now. Subaru have I heard very little from. Here in Europe you better start sell EV or you are dead. Mitsubishi have given up Europe, maybe Honda, Mazda and Nissan may be doing the same in the next year's.

Interesting. That one actually LOOKS like a Mustang, unlike the Mustang Mach-E SUV abomination.

Gates stole the window concept from Apple who paid Xerox for the right to poach employees from Xerox PARC. Xerox executives were giggling because they were shutting down the unit, firing staff, and throwing everything away, yet Apple was paying them for it.

When the Macintosh was a success Xerox tried another go at the Star.

Xerox Star was still a text-based machine. The display was formed with special text characters on a grid. IBM PC also shipped with a bunch of special text characters for drawing boxes, arrow pointer, etc. Macintosh had none of this. Every bit on the screen was a bit in memory set or cleared by the CPU. Text had to be drawn by the CPU but this meant there was no limit to the size, shape, or position on the screen. No video text generator. Apple Lisa had a text generator, but not the Mac.

IBM really wanted CP/M-86 from Digital Research, the owners of CP/M. But Gary Kildall and his negotiating team were incompetent, slow, and arrogant, so IBM took Bill Gates up on his offer for PC-DOS. Microsoft was already under contract to provide BASIC.

A small number of self-organizing autonomous vehicles significantly increases traffic flow

While this is not going to be helpful on my markings free road it may be meaningful like in LA, Houston, etc. Reaching the 5% level should not take many years in cities like that to speed up traffic flow.

All they needed to demonstrate that was Atari Frogger!

Canoo’s first subscription-only EV is a refreshing rethink of the VW Microbus - The Verge

Target = city use (tho highway capable), folks not wanting to own......... Might be on to something, for the non-TBN crowd. Hertz, 2021.

Came across it on Jay's garage..... good vid, as always. This one is fully drive by wire, and Jay has a chat with them about the drivetrain/lube mockup they were using, as well as the overall design.

Well Nissan is on thin ice financially, so I'm sure that has a lot to do with the lack of refinement of the leaf. Gotta give them props for attempting to build an EV that targets a less deep-pocketed market segment.

Honda and GM just announced a partnership where Honda will utilize some of GM's EV technology in their cars. While I wasn't surprised to see the partnership, I would have thought that Ford would have been a better fit.
