Rick is posting scientific and engineering fact. Scientific facts are unchangeable scientific truths. Engineering facts are our ability to employ scientific facts through technology to our benefit....that’s something that can change.

Technology often starts slowly with a new tech discovery, ramps dramatically, but then hits an asymptote. Look at cruise speeds of airliners...no real change since the B707, because the speed of sound is an immutable fact, as is the scientific fact that speed BEYOND Mach 1 always takes more energy than subsonic flight. Oh, you might find new technologies such as refined airfoils, materials, and engines to make supersonic more efficient than before...but a subsonic airplane will always be more efficient than a supersonic. Just physics....and chemistry.

The same with batteries and electrics. It’s about energy density, and there is no foreseeable technology, given the scientific facts, that could make them compete on a density basis with liquid fuels.

California’s recent legislation to become “emission-free” in less than 20 years is not based on any scientific or engineering principle, but rather, on good-intentions, well-wishes, and pixie dust. It’s as achievable as their low-cost job-creating high-speed rail.

Oh wait....
