My son once asked me if they had cars when I was a boy.

I think my granddaughter Maya and her secretly named sister, will not drive a car and probably never own a car. 

My granddaughter’s children will probably ask if they had cars when they were little girls.

Electric cars The death of the internal combustion engine 

It had a good run. But the end is in sight for the machine that changed the world

A Tesla sedan can beat almost any internal combustion car on the road. It was never designed as a race car. Auto racing rules are being re-designed to use electric propulsion and regenerative energy. The challenge is making the cars controllable by human drivers. 

Will people want to be fans of robotically controlled racing cars?

All electric robotic trucks are coming. Diesel robotic trucks are here now:

Electric cars can be part of the electric power grid. Electric vehicles can supplying power as needed while the vehicles are not in use and connected to the grid, a locally divided power grid soon to be entirely fueled by solar, wind, hydro and other non-fossil fuels. Entire cities in the middle of nowhere can be non-fossil fuel powered. Like say the Hawaiian islands.

Electric aircraft are here too. One flies using solar power.

The US Marines no longer need to carry fossil fuel generators, they use silent solar & battery power.

At the dental laboratory we used a water powered torch for pinpoint soldering. It converted water to hydrogen and oxygen. It’s expensive to make hydrogen & oxygen using electricity but solar & wind can make electric power cheap, making the  hydrogen & oxygen now used as rocket fuel as power for jet aircraft.

You’d think Wall Street would treat fossil fuel as a pariah, but Wall Street is entirely about quick, ephemeral money-making, sometimes milliseconds quick.
