Speed record set for all-electric airplane – 204.4 mph

Chip Yates does not like sitting still. Just a day after piloting his electric-powered Long EZ airplane to over 200 miles per hour – making him the fastest electric-airplane pilot in the world – he had to disassemble the airplane, pack it up and drive 2,000 miles east to Oshkosh, Wisconsin 리얼 스틸 apk. Here at Airventure, Yates continues to be busy answering questions about his record-setting run. And perhaps one of the more surprising answers is that Yates is a not a veteran test pilot 다운로드. He just got his license in June and has about 58 hours of experience, including the record-setting run last week.

When the electric vehicle pioneer bought the used airplane it had a 118 horsepower, four-cylinder gasoline-powered engine that is fairly standard for a Long EZ 다운로드. Over the course of several months Yates and his team pulled the four-cylinder engine out of the Long EZ. They then pulled the 193 kW (258 hp), liquid cooled electric motor out of his record setting battery powered motorcycle and mounted it to the back of the Long EZ realtek HD 오디오 관리자.

With the very well used (Yates calls it “abused”) lithium polymer battery back from the motorcycle in the back seat, the Long EZ was being prepared as a test bed for some of the technologies Yates needs to develop for his transatlantic flight 다운로드. But after setting speed records for an electric motorcycle, first up for the Long EZ was a speed run.

Electric Car Owners Dish on Their Real-World EV Experiences

Safety first

“I’d rather sit on batteries than a tank of gas, in terms of explosion risk,” says Olivier Chalouhi, who became the world’s first Nissan LEAF owner when he took delivery of one in late 2010 영화 취화선 다운로드. It is a sentiment that Patrick Wang, one of the first to own the plug-in hybrid Chevy Volt, shares. “There’s a ton more energy in gasoline than in the battery pack—so to me it’s not a concern at all,” he says 닥터 린타로 다운로드.

The only safety concern among a small sample of EV owners interviewed in conjunction with the May EVS26 electric vehicle symposium in Los Angeles relates to pedestrians’ obliviousness to the quiet electric drivetrain 다운로드. Chalouhi, whose LEAF is equipped with an automatic pedestrian-alert sounder, says he has not had any such issues. Yet Wang, whose Volt is equipped with a driver-actuated pedestrian-alert sound, says that sometimes in parking lots pedestrians have not noticed him, so he activated the chirping noise 다운로드.

Maintenance and driving range

Given that the battery pack is the single most expensive part on the vehicle—some estimates are up to 45 percent of the total cost of the vehicle—questions have been raised as to how frequently it will need to be replaced 다운로드.
