Charge to 70 % capacity in 5 minutes?
What current flow will this procedure require?
Greater than your average household current capacity (even on 220-volt systems), I'd imagine; greater than available from current automobile charging stations, I'd bet.
Heard a rumor: Electricity is sometimes generated from incinerating, "fossil fuels." Burning oil/coal at a generating plant, then transporting the electric power over long distances through lossy cables, produces a greater "carbon footprint" than . . . dare I say it? Operating a conventional internal combustion fossil fuel engine for the same energy output.
Thus, analyzing the total picture, electric-powered vehicles aren't necessarily very "green."
Never mind the fish-kill and other environmental destruction wrought by the Chinese battery manufacturers.
Electric vehicles nonetheless offer feel-good, self-righteous smugness for their trendy and chic owners, who relish their tax-credit subsidies from the government (actually, from taxpayers). The myth of environmentally-correct "green" power will live on.
Not a problem; free enterprise at work. Well, not exactly free, given the government support and subsidies to the industry and its consumers. Consumers should be free to buy the products they want. Yet, I can't endorse the myth of the "clean, green" electric vehicle, just yet.
