Let’s dig into that a bit. According to JetPack Aviation, a liter of jet fuel has an energy density of 9.6 kWh and weighs about 0.8 kilograms. That translates to 12 kWh per kilogram. In comparison, some of the best lithium-ion batteries have an energy density of 265 Wh per kilogram. The net result? Jet fuel has almost 50 times more energy available per kilogram to power an airplane than batteries do.

The same applies for electric cars too. Hauling all that weight around is not free. Also batteries put out less and less energy as they age. But they never weight less. Compare that to liquid fuel. As you use it up it weighs less and less.

Just one on many reasons why electric vehicles make no sense.

When you're pumping gas into your tank at a gas station, you're "charging" your car's "chemical battery" at the rate of about 4000 hp. That's how much energy per second is flowing through the fill hose and nozzle.

Put another way, in order to "fill" (recharge) an electric car at anything like the rate that one fills the tank with liquid fuel, you would need the equivalent of a diesel electric locomotive engine for each pump at the station. For a station with eight pumps, that's 32,000 horsepower if they're all in operation at the same time.

That means that an eight-pump station would need a 15 megawatt electric supply for a maximum-load scenario.

That's if it were possible to charge a battery pack as quickly as one can transfer energy in liquid form.

Those numbers assume automotive gasoline engine efficiency of 30%, which is a bit optimistic.

Don't even ask about the size of the cables that would be required to carry the necessary amperage.

Also electric powered vehicles do not get lighter as the energy is used as with a fueled vehicle.
