The blog broke when I tried to comment there, so I'll comment here.

Quick change battery packs, and a support infrastructure for them might solve the problem of long distance travel for electric cars. You drive, you get low on juice, you pull into a "gas" station, and they swap your dead battery pack for a live one, charge you a fee for the electricity and amortization cost on the battery pack, and you're on your way. You'd need to standardize the interface for a wide range of vehicles, (like how AA is a standard, only much much bigger) and get the swap time down to something comparable with a regular gasoline fuel stop.
