High school senior Don Gibson decided to do something to combat the high price of gas. He converted this 1994 Geo Metro to run on electricity. He ﬁgures it costs him about 25 cents to charge the car’s batteries for a 20-mile drive, the equivalent of about 200 mpg.

riving is a right of passage for teens. But when gas hovers near $4 a gallon, that milestone loses its luster. While others parked their cars or limited their trips until the price went down, Don Gibson of Grant City started work on converting a 1994 Geo Metro to run on electricity. “I went ahead and grabbed an electric motor that was available on eBay for $450,” says Don, a senior at Worth County R-III High School. “It was a fork lift motor. Someone had bought it and rebuilt it.” Don had read online about a Wisconsin man who completed a similar conversion, and that inspired him to give it a try. Using money he made ﬁxing computers, he bought a wellused Geo and pulled the motor, along with the exhaust system and gas tank. The electric motor was a perfect ﬁt. But getting a coupler made to connect it to the car’s 5-speed transmission was a challenge in this region where cows outnumber people 10 to 1. “Trying to ﬁnd a machine shop around here is hard,” Don says. “We ended up trying to fashion a number of parts by hand, with hand tools.” Eventually, persistence paid off and a shop was found that fabricated the essential piece. “One thing about Don, when he starts talking about something, there is a high probability he will do it,” says his dad, Reid, publisher of the Grant City Times-Tribune. “I tell people, ‘My son is studying to be a Japanese industrialist.

A six-hour charge gives him just enough juice for a round-trip journey from home to school, around 16 miles. Normally, he tops off the charge at the newspaper ofﬁce on the courthouse square in Grant City. “It pulls about a kilowatt of electricity,” Don says. “Compared to the cost of gasoline, that’s nothing.” Charging the car takes only about 25 cents worth of electricity, he ﬁgures. While the original design of the car provided an estimated 42 mpg, it does much better on electricity. “We did a comparison, and this will do the equivalent of 200 mpg,” Reid says. The electric vehicle’s lead-acid batteries are the limiting factor in making The Blue Zeus practical transportation. The low-tech batteries are heavy and lose their power quickly. Lithium-ion batteries would lower the weight and could extend the range to 100-plus miles, but at a huge cost — more than $3,000. With the car almost perfected, Don is looking ahead to his next big project. He already has a wind-powered charging station in the works. When that’s functioning, he wants to start building a solar-powered vehicle. “It’s quite possible I will come up with some other harebrained idea, and it will get further along than my solar car,” he says, laughing. “My real passion is designing things that could help humanity. There’s so many things you could ﬁx just by changing how we use and produce energy.” You can contact Don at 660-5643603 or firstname.lastname@example.org.
