SMA Solar Technology AG enters micro-inverters market through acquisition ~ Cleanergy.org - Energy Efficiency, CleanTech, Solar, Wind, Hydro...
-
Micro inverters are particularly well-suited for the use in small photovoltaic systems of 1 kWp or under. In some larger photovoltaic systems which use string inverters, shading of individual modules and the subsequently lower energy harvest of the entire system can be avoided by equipping and operating those modules with individual module inverters.

Space Elevator: Science Fiction or Global Warming Cure? - PC World
-
A space elevator would essentially be a long rope made of nanomaterials, stretching from Earth to a counterweight at geosynchronous altitude, about 22,000 miles (35,406 kilometers) above Earth's surface. Special craft, like elevator cars, would travel along the ribbon, carrying people and goods into space in a matter of days.
