ClarianLabs: Rethinking The Battery As A Tiny Engine

An energy technology incubator, ClarianLabs in Seattle, has published a patent for a device called the Rotary Piston Generator (RPG) which the company hopes will challenge the idea of what batteries are, and how they're used, especially in vehicles. The RPG is a mechanical rather than chemical approach to portable energy storage. Its energy capacity is potentially ten times greater than a typical battery, company representatives wrote in an email exchange with TechCrunch. That depends on the kind of fuel it uses? the invention is essentially a very tiny, highly efficient engine.
