I’m actually having fun tech-wise using a small amount of this sort of thing in my own life.
I don’t ask government to help me. I don’t do it because the government told me I should. It’s just for a hobby. Same reason I’ve started using a couple LED light bulbs around the place. (they’re not bright enough to use for most things yet)
Nothing wrong with technological advancement. It’s just when government gets involved, things go wrong.
At the moment I’ve got a small electric scooter I use on weekends to run short errands with. It goes about a mile round trip.
Hypothetically it can be charged solar. That’s not available with the scooter, but I rigged together a small solar charger.
Thing is, it takes about a full sunny day, to charge for that one mile round trip.
It’s fun to jump on it and zip over to the market, without using gas. It’s interesting to be marginally able to recharge it without the grid. As a hobby.
But the technology just isn’t ready yet for prime time.
Not even close to being better than gasoline yet.
If any success comes from this new-fangled way of "saving the planet", a lot of it will come from folks such as yourself...the backyard/hobbyist-type inventors and experimenters.
Just be sure to patent it, and don't sell your idea to the bigs boys for a song.
