Question Earthority!

“The idea of the Hypercar^TM has been around longer than the name. Build an ultralight car that is reasonably aerodynamic. (No, it does not have be a tear drop; you have a choice of a lot of shapes.) Drive it with electricity — even if the electricity is generated from an on-board gasoline-powered generator. You still end up with better efficiency than using straight gasoline to power light normal internal combustion cars. Alternatively, you can make an all-electric Hypercar^TM, like the prototype Sunrise that Solectria demonstrated back in 1997, which ran off a 30-kWh battery pack and had a 216-mile range (a bit more than the Tesla with its 56-kWh pack). Let’s look at the economics of a PHEV and an EV car with today’s technology.” (07/26/07)
