World’s Largest Airship Lifts the Standard for Efficient Blimps Posted: 14 Apr 2010 08:32 AM PDT A new airship from E-Green Technologies/21st Century Airships sports the crackerjack name Bullet 580 along with a “radically different” design according to E-Green Chairman and CEO Michael Lawson.

This makes converting a conventional car to electric power especially daunting, as many available electric motors simply don’t make as much power as petrol engines. While you can slap a supercharger on a low-displacement petrol engine, there is no such easy fix for electric cars. Tokyo-based Teijin has unveiled a lightweight electric city vehicle made from composite materials. So is this just a pipe dream project, or something that might one day see production? (more…)
