NASA, airlines are trying to put all-electric jets in the air
Commercial airlines and NASA are pushing U.S. researchers to take another stab at mastering a futuristic battery that will allow the use of all-electric passenger jets.
NASA has funded a battery project to power a regional, nine-passenger all-electric aircraft. It has pulled together a team including researchers from IBM, Cal Berkeley and Carnegie Mellon University to resolve problems that have dogged lithium-air, a battery concept that, if figured out, could deliver energy density close to that of gasoline. The venture arms of Jet Blue and Airbus are also pushing the universities to figure out electric jets, said Venkat Viswanathan, a CMU professor who is a member of the NASA project.
Why it matters: NASA says a lithium-air propelled electric plane could reduce airliners' operating costs by 30%, plus reduce emissions. In addition, a lithium-air battery — if finally figured out — could eventually revolutionize cars, since they could travel 500 miles on a single charge.
