Bright Automotive, the plug-in hybrid car company spun out of the Rocky Mountain Institute this year, says it will show off its car on April 21 on Capitol Hill in Washington D.C. Earlier, it was going to debut the car at a show in Norway in May. The name of the car is going to be the Idea. C'mon. Can't you think a little harder than that? ElectraScoot? PowerDrive? Mighty-Lighty (one of the attributes of Bright's car is that it will be comparatively lightweight, which increases battery range)? How about "The same force of nature that is used to remove unsightly eyebrow hairs will charge your car!" as a slogan? People are going to confuse it with Ikea. We interviewed Bright CEO John Waters back in January. He said that the car, which will get 100 miles per gallon, can run on battery packs 40 percent smaller than competing electric cars because of aerodynamics and weight. The car drives on battery power for the first 30 miles and then switches to hybrid to get the full 400 mile range.

"It's a revolutionary platform," he said. "The platform that's been on the road today is 100 years old. [The traditional technique for making cars] uses a lot of steel."

Bright will also face the same challenges in raising capital and moving from crafting prototypes to producing commercial vehicles. But it does have experience on its side. Waters worked on the battery for the General Motors EV1 and also worked at Ener1, which makes lithium-ion batteries. Many of the other executives have years of experience in the auto business.

Weight and poor design result in a disproportionate amount of fuel consumption in vehicles, Waters said back in January. The U.S. Post Office operates 162,000 delivery trucks that get around 10 miles per gallon, he said, and these trucks drive around 18 miles a day. If those trucks are put into use 300 working days a year, that's 87.5 million gallons of gas consumed by those white little trucks trolling your neighborhood. Boosting mileage to 100 miles per gallon conceivably could save nearly 80 million gallons of gas.

A one cent increase in the price of fuel raises the operating budget of the federal government by $8 million, Waters said.

It hopes to be in mass production in 2012. Initially it will target the delivery business.
