On topic, I noticed a company called
Betavolt has started making atomic batteries. The article said they were very low power but worked for 50 years without a charge.
It strikes me everything like this starts small but scales up over time ... or dies a death and is never heard from again.
A
UK company has made a super-fast charging battery.
I see two big problems with battery power - range against charging time, and the cost.
I can buy a small Ayla for a little over a hundred million and 'recharge' in a few minutes. That gives me an effective unlimited range as far as practical use of the car goes.
An EV of about the same size starts at 400 million and takes hours to charge.
People who regularly travel long distances save money on fuel costs, but they are limited on range per day.
People who do short hops don't worry about the range, but the fuel cost savings EVs offer are wiped out by the initial cost of buying an EV.
At the end of the day, the things are a bad buy for most people.
The only EVs worth buying at the moment are small bikes like the unit I have. They are cheap to buy, cheap to charge, and work perfectly for short runs around town.
When we can say the same about EV cars, we will have something the masses will buy.
Yesterday saw a hailstorm in Depok when it should have been 30 degrees and maybe raining. Climate change appears to be a real thing but, even if you don't believe in it, cleaner city air and less noise are desirable goals.
If the world can shift to renewable energy, that takes care of the problem of the 'moving the pollution' argument.
