Broadcasters who use satellites canít accept shutdowns, even when they happen only twice a year during eclipses. The Optus D3 satellite made by Orbital Sciences Corp. will use rechargeable lithium-ion batteries from Saft for power when the spacecraft is blocked from the sun during two eclipses. The two rechargeable Saft lithium ion 180W/hour average cells trim weight in half compared to alternative technologies studied by Orbital, letting the company add more critical payload equipment. It carries 32 transponders that will provide Ku-Band direct television broadcasting services to Australia and New Zealand after 2009.
Automakers are on the prowl for lighter weight materials to make vehicles less heavy and more fuel efficient, and Nanosteel is one of the companies hoping to take advantage of this opportunity with their lightweight automotive steel of the same name.
