DeviceGuru writes "Electric vehicles were prominent among the 'hot products' showcased at West Coast Green in San Francisco this week. The event's product expo featured an assortment of preproduction units, prototypes, and concept models based on two-, three-, and four-wheel designs, along with several of the vehicles' creators. Specifically, the EVs and plug-in hybrids that participated in the show included Wheego's Whip, Saba's Carbon Zero Roadster, Green Lite's three-wheeled plug-in hybrid, Brammo's all-electric Enertia motorcycle, and Mitsubishi's i-MiEV EV, which PG&E is evaluating for some unstated purpose. Notably absent were Nissan's LEAF, Chevy's Volt, Toyota's Prius Plug-in, and Tesla's sexy Roadster, though in fairness the conference wasn't an actual auto show. So how many Slashdot readers plan to switch over to a plug-in EV in the next few years?"
