Student builds solar motorcycle, launches club to push more electric vehicle breakthroughs

( -- A Purdue University student who created a solar-powered motorcycle is launching a club to help likeminded students expand environmentally friendly transportation options.

Physics major Tony Danger Coiro, a junior from South Bend, Ind., received a provisional patent for his that uses solar energy to cut his transportation costs down to well less than a penny per mile. The lead acid batteries also can charge from plug-in AC current.

After purchasing a 1978 Suzuki for $50, Coiro spent $2,500 redesigning and retrofitting the bike, which gives him a range of up to 24 miles per charge and top speed of 45 miles per hour.

"The riding experience is surreal," Coiro said. "I get instant, silent, constant acceleration that outpaces urban traffic. It's like riding a magic carpet."

Coiro co-launched the Purdue Club with Jim Danielson and Sean Kleinschmidt, two sophomores from suburban Chicago. Danielson and Kleinschmidt spent their summer after high school converting a 1987 Porsche 924S they picked up for $500 to electric power. Kleinschmidt, a mechanical engineering major, translated that success into a summer internship at Tesla, where he helped develop batteries for the makers of the world-class, all-electric sports car. Danielson, who is majoring in electrical and computer engineering, spent his summer developing motor control electronics for Electro-Motive Diesel, which designs and manufactures diesel-electric locomotives.

"Purdue Electric Vehicles will encourage enthusiasm for, and knowledge and development of, electric vehicles by students and the community," Coiro said.

Coiro's motorcycle and the electric Porsche and will be displayed on campus at the Stewart Center bike lane on Oval Drive from 11 a.m. to 4 p.m. Wednesday (Oct. 6) as they compete in Purdue Green Week's alternative energy vehicle show. Coiro, Danielson and Kleinschmidt will be at the show to talk to visitors about their cars and the club.

Coiro said the Purdue EV Club will patent and commercialize its breakthrough technologies and feed proceeds back into research and development of new prototypes. Coiro is already designing a 100-horsepower motorcycle that will travel up to 100 miles per charge, top 100 mph and draw even more of its energy from the sun. The all-wheel-drive bike would include motors in each hub and no drive trains.

"I've learned a lot building this first bike, and now I'm ready to make a game-changer," Coiro said.

Coiro, Danielson and Kleinschmidt oversaw construction of the 17 electric race karts that students built for the first-ever electric vehicle grand prix, held at Purdue this spring.

In 2011 that race is expected to draw student teams from throughout the Midwest. The race was created by Purdue's Indiana Advanced Electric Vehicle Training and Education Consortium to demonstrate the possibilities of electric vehicles and train a new breed of young engineers to improve them and reshape the auto industry in Indiana and beyond.

"Electric vehicles are four to five times more efficient than internal combustion engines - that's a big difference," Coiro said. "They're not the solution to our energy problems, but they will be an increasingly bigger piece of the puzzle."

When he graduates, Coiro plans to launch a company that develops electric vehicles. Eventually, he foresees launching a not-for-profit energy company.

"Gas is not in infinite supply, so we need to go to another energy source in the future, be it nuclear fusion or fission, solar or wind," Coiro said. "It's going to be a lot easier to charge an electrical vehicle off of the grid."

I built an electric motorcycle on a Honda 175cc Scrambler chassis, with two saddlebag style mounted 105 amp-hr batteries and a 3hp golf cart motor in 1981 in Key West. I charged it with two 40 watt solar panels on my boat, having two sets of batteries. Performance was about 50 mph and at least twenty miles. Quiet, superb acceleration.

I hope this dude doesn't get a swelled head. I'd build it with a hub motor and LiPoFe and a transistorized controller now, or just buy one of the fifty models available in China.

Can't find anything on LiPoFe batteries. Just LiPo.

What are they?

That's cool, although the mileage kinda sucks.

@ormondovots - do the world a favor, post the howto on the Instructables!

pretty good.. but can you ride while solar is charging the batteries ?

I have built a fully functional solar bike with solar panels as the front fairing.
