You are on the money, 5 minutes to 80% makes it possible to actually pitstop an electric car. This would be huge.
The problem with all electric cars is that efficiency of the car is largely illusory. Power Plants are enormously efficient conversion mechanisms for heat into electic power, but lots of energy is lost along the path of getting it into the car vs. just burning the fuel and using it to crank the tires via heat expansion. And, the other little problem is that the Dems have been shutting down virtually ALL power plant construction since the 1980’s. This has left the vast majority of power plants in service more than 50 years old. The design lives of these plants were 30 years.. and no one sees a problem. This is largely due to the efficiency of Gas Turbine technology and fracking. But, would the Electrical Grid actually take an increase of 10% or 20% to really offer energy for a similar percentage of electric vehicles? Nah.
Dalight. Yes!
We need plants, you mentioned Gas Turbine aka Combined Cycle plants could be a huge bridge between Gen 3 & 4 Nuclear comes along. Can you imagine the blue collar jobs created to rebuild the grid!
I still think the firm that comes up with a Cogeneration Unit for your home (Esentially a Generac that uses the waste heat) that can heat,cool and charge your house and your car, via natural gas which is already has an installed infrastructure in many locals is a huge series of wins, including getting rid of the "line-loss".
