Broadcasters who use satellites can’t 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.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
