  > can be a viable option To win the northern market, without massive subsidies, electric cars need to be better than viable. They need to be better than gas car. In cold weather, that will require an order of magnitude increase in energy density. That's a couple decades off imho.

    The energy density of aluminum batteries is higher than that of gasoline as they essentially burn aluminum turning it into Al2O3. The problem is that they are typically not rechargeable making them very costly presently. But with right infrastructure they can be better than gasoline - putting aluminum bars into the car should be even easier/faster than pumping gasoline. And, as with gasoline, they do not loose energy when left in cold.
