New Batteries For EV's

Fossil fuels may be phased out in the same time frame, although probably not. Eventually they will be gone.
Well not in my lifetime. An EV is one thing but what about planes and boats and trains? How about sea going freighters? Making an EV automobile is one thing but even making an electric semi tractor-trailer is a whole new adventure and how about cost involved? I see Fossil Fuels being around for a long time.

Hi Ron,

Ironically they will probably continue to need fossil fuels to make EV's and batteries ha ha :)

I guess the main problem is we still do not have a good renewable source of energy yet. I love solar and solar is great but when clouds persist for several days in a row, you're screwed.

Germany has too many solar panels, and it's pushed energy prices into negative territory
Sunny days in Germany mean gray clouds for solar profitability as the nation's dive into renewables has left it with too much energy.

According to a note from SEB Research, in the past 10 days, solar producers have had to take an 87% price cut during production hours. In fact, when production peaks, prices have slid well below zero.
The solution is easy, pay people to use electricity. :p

China's blistering solar power growth runs into grid blocks
The problem has hit several regions that were heavy adopters of distributed solar, which made up 42% of the national solar fleet last year, but is especially acute in provinces such as Shandong in the north.
State broadcaster CCTV said up to 50-70% of distributed solar generation is being curtailed in Shandong, which means grid managers have had to stop that amount of supply coming into the grid in order to maintain balances with demand.
China has tried to limit curtailment of renewable energy to 5%, in line with rates of 1.5-4% in most big markets, according to the International Energy Agency.
But in a survey of six provinces' ability to absorb distributed solar, China's energy regulator last year found five expected to have to impose restrictions on new projects in 2024.
Hebei and Henan provinces - two of the "three big drivers" of distributed solar along with Shandong - have already seen an "absolute collapse" in installations, Ries said. "These two provinces are very worrying."
The solution is easy, pay people to use electricity. :D

Idiots are with us always, else the Darwin awards would go out of business.say what you will I have never had a good opinion of John Q Public.

Even though they are far from perfect we do have self driving cars now. And they are commercially available.

You know what makes me think here. Long time ago I thought it would be impossible to make an electric car that actually worked for anything useful. That's because I had experience with some giant motors with enough horsepower to run some pretty big things, and they were very heavy and took a LOT of power. To get anything like a car engine I figured it would require a big motor and a giant battery. I never thought that anyone would be crazy enough to install a giant battery in a car. It takes up a lot of room and weighs a ton, and rechargeable batteries (at least back then) would not last forever so the entire bulk would have to be replaced at significant cost.

Fast forward to today we have more advanced technology like rare earth magnets, lithium based rechargeables, and first and foremost, really, really crazy inventors :)

And you were exactly right.

Just to be clear: there have been no inventions that have improved the economics of EVs over the past 120 years, unless you consider the transfer of cash from poor Americans to rich ones an "invention".
