I’ll say that I sort of despise Fairvote.
They lie about RCV pretty much all the time.
The system has more problems than First Past the Post, and still doesn’t fix the third party problem.
No, a far better system is STAR. It actually fixes the problems that it sets out to fix.
Hydrogen fuel cells actually show quite a bit of promise. Mostly for large trucks. Batteries have a scaling issue. A battery powered 18-wheeler needs a much larger battery for a much shorter range.
Adding more load means you need more battery, and that larger battery is just more load that you need to haul.
This is sort of true with everything, but the important note is that a full battery and empty battery weigh the same.
Anyway. Commercial use is where it makes sense. There are actually a few other technologies that make sense in the commercial transportation space. Like ammonia.
Keeping these rather dangerous fuels commercial also allows for more strict safety standards.
