Hawaii Electric Cars

The island state has signed up to a Plan for Electric Cars:

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.


“We always knew Hawaii would be the perfect model,” [Shai Agassi] said in a telephone interview. “The typical driving plan is low and leisurely, and people are smiling.”

Cute. San Francisco and other Bay Area cities already have endorsed the same electric car network, perhaps with even more smiles.

I spoke with a representative from an electric company recently, as I was working on NERC Cyber Security, and he bemoaned the fact that electric cars are starting to burnout the electric grid. A Tesla roadster, for example, pulls at 240V and a few in a neighborhood could be a major problem for the infrastructure. This reminded me of a house I owned in 1996 where we tried to install a T1 and were told by the phone company that they would have to pull a new line from four states away to provide the bandwidth.
