St. George is famous for slaying a dragon, but he’d have a real challenge on his hands if he showed up today in Furth im Wald, Germany. There he’d discover the streets of this town of 9,000 being stalked by an 11-ton fire-breathing dragon with a steel skeleton and a diesel engine for a heart.

World’s largest OTEC power plant planned for China

Lockheed Martin has been getting its feet wet in the renewable energy game for some time. In the 1970s it helped build the world’s first successful floating Ocean Thermal Energy Conversion (OTEC) system that generated net power, and in 2009 it was awarded a contract to develop an OTEC pilot plant in Hawaii. That project has apparently been canceled but the company has now shifted its OTEC sights westward by teaming up with Hong Kong-based Reignwood Group to co-develop a pilot plant that will be built off the coast of southern China.
