Researchers at the U.S. Naval Research Laboratory (NRL) have set a new continuous flight record with an electric drone powered by a fuel cell running from liquid hydrogen in cryogenic storage. The Ion Tiger unmanned aerial vehicle (UAV) flew for 48 hours on April 16-18, shattering their previous record of 26 hours set in 2009 […]
An innovative wireless system that charges electric cars while they are on the road could also be used to control driverless electric vehicles, say the Stanford University team who designed the system. While the new technology has the potential to dramatically increase the driving range of electric vehicles, the researchers concede that large-scale deployment of […]
