Virgin Galactic Completes Second VSS Enterprise Rocket Test FlightOn Sept. 5, SpaceShipTwo achieved supersonic flight hitting mach 1.43 during its climb from its release point at 42,000 feet to 69,000 feet (21 km) over the Mojave Desert. In addition to achieving the highest altitude and greatest speed to date, the test flight demonstrated the vehicle's full technical mission profile in a single flight for the first time ... All of the test objectives were successfully completed.

Nanotechnology to produce thin films with special quantum effects.
In traditional semiconductor cells, such as polycrystalline silicon solar cells a single photon can only excite a single exciton. Typically photons from our sun have more than twice the amount of energy needed to excite one electron, so in these materials after excitation this extra energy is lost. Thus the maximum theoretical efficiency of traditional thin film cells is around 45 percent.
Nanotechnology can be used to produce thin films with special quantum effects. One major research push is to work on the exciton generation, in so-called "excitonic solar cells" such as quantum-dot based dye-sentized solar cells (DSSCs) and other new/exotic material cells. The goal here is to find materials that create multiple excitons from a single photon, a phenomena known as MEG (multiple-exciton generation). The LLNL work (study) made layers of ordered nanopillars about 50 nanometers in width and between 250 and 1400 nanometers (1.4 µm) in height. Nanowire thin films of gold, aluminum, and silver were tested. The study indicated that taller nanowires perform the best. And surprisingly the aluminum -- while more reflective (88% avg. reflection) than gold (74%) in unpatterned flat films -- performs the best in black metal films, covering the broadest array of spectrum including the entire visible range.
