I do not failed to notice the commercial and political push toward battery-based EVs, I do not notice that they can be sustained in the mean and long run. We can't produce and dispose enough battery to electrify our personal vehicle only at country-scale, we can't produce and distribute enough energy to charge them. Consider that at a certain scale we can do tons of things, but only at a certain, limited, scale. In Germany hydraulic-propellers for trains are still fairly common, they are super-duper complex to design and maintain but they was pushed as a flag of excellent German industry decades ago and they have them even if are monsters and does not really scale nor offer any practical advantage. In the '60s Italian Ansaldo have designed and build electric planes with electricity generator inside the fuselage, they fly well but they can move around half the load of the correspondent classic-design plane and they cost more, another Italian industry, Fiat, have built personal cars with a jet-mini-turbine engine as a power generator + electric motors, they works however they are so noisy, they eject too much heat, they consume so much fuel that they simply drop it. The fact that we can do something it does not means automatically that it's a good things to do nor that can scale. We can save enormous resources and improve our lives building energy-efficient houses so it's a good move, we can't for now produce electric vehicles so we have to research (a forgotten thing in managerial-era) but not try to push something we know can't scale.
