Hi - 1st post on Haker news. Please be nice :)

Aren't debates over energy density of super conductors v. Li-Ion batteries missing the important point, relative cost?

E.g. If the energy density is 1/4 lower but the cost is 1/40th as much then electric cars get ALOT more viable. Can anyone guess at the relative cost?

How important that point is depends on how much range affects viability as opposed to the cost of the vehicle itself. Electric cars are rather expensive I guess, but few people are going to make the switch to cheaper cars if they only have a range of 20km.
