@KarlHeinzHasliP @denki Personally, I think that standardized #batteries that get swapped would've been the solution to the charging speed problem.

#BEV|s are a problem and the #EnergyDensity and #Charging problems are hard walls that can only be circumvented (i.e. swapping fluids at a #RedoxFlow-#Battery) or ignored (i.e. #Methanol #FuelCell)...

• Personally, I think #Trolleybuses are the best option if #Trams & #Trains ain't feasible (i.e. steep grates like in #Solingen) and the few edgecases that'll never get 24/7 once per hour bus service or even an on-call minibus need to get more efficient without #ConflictMinerals from #UnfairTrade (i.e. #Cobalt) and destruction of unique habitats (i.e. #Lithium)...

Solving the #EnergyProblem isn't a technological issue, but a political one (see #DESERTEC)...
