SpaceX Achieves Key Milestone of Tenth Launch Agreement  - SpaceDaily  SpaceX announced that the number of launches on manifest has now reached double digits. The ninth launch, already announced, is with MDA Corporation of Canada and will carry the Cassiope satellite on a Falcon 9 in mid 2008. The tenth launch agreement is a second responsive launch demonstration of the Falcon 1 for DARPA / Air Force in late 2006. This follows the first responsive launch demonstration in March 2006, which was also the maiden flight of Falcon 1. - Falcon 1 DARPA - Air Force Demo 1 Q1 2006 (Launched in March 2006) DARPA - Air Force Demo 2 Q4 2006 NRL - OFT TacSat 1 Q4 2006 - Malaysia RazakSat Q3 2007 - SpaceDev Q2 2008 - MDA Corp Q3 2008 - Swedish Space Corp.

An Alternative to your Alternator  - Technology Review  Left: A "thermophotovoltaic" (TPV) generator burns fuel to heat a material that emits light (labeled "radiator"). The light is then filtered and converted into electricity in photovoltaic (PV) cells. (Image courtesy of John Kassakian, MIT.)  Researchers at MIT are developing new technology for converting heat into light and then into electricity that could eventually save fuel in vehicles by replacing less-efficient alternators and allowing electrical systems to run without the engine idling. The technology, called thermophotovoltaics, uses gasoline to heat a light-emitting material, in this case tungsten. A photovoltaic cell then converts the light into electricity. The idea has been around since the 1960s, says John Kassakian, MIT electrical engineering and computer science professor. But until now, the light emitters for the photovoltaics produced inefficient and very costly systems. Improvements in the materials used in these latest devices are now making much more efficient systems.  

Teamwork with elbowroom -- tabletop computing  - CNN  Mitsubishi's DiamondTouch displays a PC screen on a high-tech tabletop. People sitting around it use their fingers to create and manipulate projected virtual objects, with the system knowing whose fingers did what thanks to small currents of electricity that flow through the chairs. Masakazu Furuichi, chief engineer at the Japanese electronics maker, hopes DiamondTouch will become a tool for games, government decision-making, education and other areas in which several people need to interact intuitively and instantly. But first the price will have to drop -- the tables can cost as much as U.S. $10,000 (euro7,700) each.
