The State of Hawaii and the Hawaiian Electric Company on Tuesday endorsed an effort to build an alternative transportation system based on electric vehicles with swappable batteries and an “intelligent” battery recharging network.

The plan, the brainchild of the former Silicon Valley software executive Shai Agassi, is an effort to overcome the major hurdles to electric cars — slow battery recharging and limited availability.

By using existing electric car technologies, coupled with an Internet-connected web of tens of thousands of recharging stations, he thinks his company, Better Place L.L.C. of Palo Alto, Calif., will make all-electric vehicles feasible.

Better Place was written up in Wired a few months back... this is definitely an interesting approach.
