Laws of physics haven't changed the way entrepreneurs would like them to change.
Theoretical energy density of an electric battery is low. Practical energy density of electric batteries today is even lower that that. There is no specific known approach to make better batteries, everyone experiments, and tests, and experiments, and tests over and over again hoping to discover a magical combination that keeps lithium stable.
Unless someone discovers a completely new physical effect (I wouldn't bet on that), electric cars are never going to be versatile. And if there is a discovery like that, I doubt they are going to rush to implement new technology in, essentially, rich consumers' toys. There are more important areas.
- rrrrrrrrrrrryan 6y agoI feel like electric cars suffer more from infrastructure problems than physics. If there were widely available chargers at both workplaces and homes (including the parking garages of apartment complexes, etc.), I think you'd see much more widespread adoption. It's not hard to imagine widespread fast-charge stations off the interstates, or even battery-swap stations either. ICE cars have basically a hundred years of infrastructure to lean on, and they'll continue to have a massive one-up on electric cars in terms of versatility until an equivalent electric infrastructure is built out.
