My Ram 1500 will go 475 miles if I keep it below 70 miles an hour. At 80 it will give me 400 miles. When an electric Truck will do this at the same price and recharge the batteries in 5 minutes all at the same price I will buy it.

With today’s technology that will not happen.

The real deal is energy density. Hydrocarbons have the greatest energy density, we call that gasoline and diesel or in the airlines Jet-A. There is a damn good reason 777s run on Jet A and turbines, batteries are heavy, very heavy.

Enthalpy is good, Entropy always wins.

Not all batteries are heavy, yes edison batteries are heavy as are lead acid, ni-cad are lighter ni-mh are too.
Supercapacitors are light

We have been increasing battery capacity per unit of mass for a while and as massive money pours into this it will continue.

More of a problem is a standardized charging infrastructure.

But soon enough the Mr. Fusion breakthrough will change everything.

Recharging an electric vehicle in 5 minutes is impractical to the laws of physics. I remember reading a column called “Ask Hank, He Knows” in the old magazine, “Elementary Electronics,” January/February 1980 issue. Someone wrote in where he claims someone made an electric vehicle where it can go 300 miles, has a 40 hp motor and you can recharge it in 5 (or 15?) minutes or so. Hank wrote where if that was the case, your house would have huge, low gauge wiring and the amps to do that will be so huge that it would cook the battery (not good) and even “make it glow.”
