http://www.freep.com/news/statewire/sw120465_20050828.htm ANN ARBOR, Mich. (AP) -- Terry Richards isn't too worried about the recent jump in the price of gasoline. A test specialist at Chrysler Group's proving grounds in Washtenaw County, Richards rides a 21-year-old racing motorcycle he converted into a fully electric-powered vehicle for about $2,000. "I just kind of thumb my nose at them, and it feels good," Richards, 47, told The Ann Arbor News for a Saturday story. The 1984 Yamaha RZ350 now runs on electricity stored in four batteries. Richards calculates spending 4 cents per mile to operate it and averages about $15 worth of electricity per week if he rides it every day. "I study a lot of material about alternative energy sources, and I had a pretty good idea (the price hike) was going to come, and fast," Richards said. Richards and his wife, Rosemary, still do the majority of their driving with their two sedans. On Aug. 22, AAA Michigan reported that the statewide average for a gallon of self-serve, unleaded gasoline was $2.70, up 14.8 cents from the previous week and 73.3 cents higher than last year at the same time. Richards' motorcycle cruises at 40 to 45 miles per hour and can reach a top speed of 60 mph, he said. The batteries take a total of about fours to fully charge and provide enough juice to average about 16 miles per use. It's enough to make his 13-mile daily commute to work, where he has permission to plug in to an electrical outlet. He also regularly rides in to downtown Dexter, where he says people marvel at the quiet engine. "I've had joggers jump out right in front of me because they just don't hear it," he said.
