Proterra’s E2 series 35-foot electric buses feature a 440 kWh battery pack with an estimated range of 251 miles. Proterra was bidding against BYD for the airport contract, and won the sale with a price of $759,824 per bus.
Proterra will design and build the buses at its Los Angeles County manufacturing facility. They are scheduled to go into service in late 2018.
The E-Fan X is an important next step in our goal of making electric flight a reality in the foreseeable future,” said Eremenko. “The lessons we learned from a long history of electric flight demonstrators, starting with the Cri-Cri, including the e-Genius, E-Star, and culminating most recently with the E-Fan 1.2, as well as the fruits of the E-Aircraft Systems House collaboration with Siemens, will pave the way to a hybrid single-aisle commercial aircraft that is safe, efficient, and cost-effective. We see hybrid-electric propulsion as a compelling technology for the future of aviation.”
Fisker reports that its solid-state technology enables the construction of bulk three-dimensional solid-state electrodes with 25 times more surface area than flat thin-film solid-state electrodes and extremely high electronic and ionic conductivities. Fisker claims its battery delivers 2.5 times the energy density of current batteries.
Three major school bus manufacturers – Thomas, Blue Bird and IC Bus – introduced battery-electric buses at the recent National Association for Pupil Transportation trade show in Columbus, Ohio.
Magnesium, on the other hand, has a higher energy density than lithium and is far more abundant in the natural world, meaning devices made with the stuff should be cheaper and easier to produce.
The company is leasing an Arizona proving ground to experiment with its nascent autonomous platform, according to a Jalopnik report citing a source familiar with the project. The facility in Surprise, Arizona was previously owned by Fiat Chrysler, which took advantage of the area’s brutal climate to conduct tests on how heat affected its vehicles.
Keller Rinaudo wants everyone on earth to have access to basic health care, no matter how hard it is to reach them. With his start-up Zipline, he has created the world’s first drone delivery system to operate at national scale, transporting blood and plasma to remote clinics in East Africa with a fleet of electric autonomous aircraft.
