(Phys.org)—Look what an Australian designer would like us to roll with in a no-emissions future: A motorcycle powered by nothing but air. Adding to a growing portfolio of ideas centered around compressed-air engines, this ...
(Phys.org)—Technologists generally agree that power amplifiers have proven to be inefficient pieces of hardware. Turning electricity into radio signals, they eat into the battery life of smartphones and they waste power. ...
(PhysOrg.com) -- An underwater tidal turbine called an “underwater kite” has just secured finance from investors to ensure its 2011 tests can go ahead.
(PhysOrg.com) -- A town in Britain has recently demonstrated its new "'leccy vehicle" - an electric garbage truck that is fueled by the garbage it collects. The Kirklees Council presented the waste-powered Ford Transit garbage ...
