That is more than ample for most commutes. Of course if you have the money for one, paying for gas ain't the problem. -- ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =----

Only thing is, owners need to have a dedicated, 3 phase power outlet available at home with a capacity of 15 kW - then it will costs about $10 or so in electricity for a full recharge. However .............. - just load the boot (ie trunk in the USA) with a bunch of these babies and get it done in only 1 minute !!!!! http://www.dcviews.com/press/Toshiba-One-minute.htm All you need is ** 3 megawatts ** capacity in the garage !!!!! Circa 4500 amps per phase . ........ Phil

Household nuclear reactors, anyone? :) The owners will get a better deal on the power if they let the power company control the charging current. The feature will be built into the charger and most people will use it.

A marketing company too, not scientific researchers. I'll pass on that. Graham
