An eco-car that can travel the world using a fraction of the electricity it takes to power a light bulb has been unveiled by its British creators. The hydrogen-powered Ech2o needs just 25 Watts -- the equivalent of less than two gallons of petrol -- to complete the 25,000-mile global trip, while emitting nothing more hazardous than water. But with a top speed of 30mph, the journey would take more than a month to complete. Ech2o, built by British gas firm BOC, will bid to smash the world fuel efficiency record of over 10,000 miles per gallon at the Shell Eco Marathon. The record is currently ... 5,385 km/per liter [12,900 mpg!]. John Carolin, BOC global director sustainable energy: It sounds unbelievable how little power is used to keep the BOC Ech2o moving, but it demonstrates the impact of careful design and is a valuable lesson for car makers in the future.

Each news summary is created according to strict standards. Here's how we do it.
Each summary is created using a consistent editorial procedure. The target length is approximately 16 lines of 11-point Arial text in a 650-pixel-wide column. Up to 25% of a summary may be set in bold to emphasize the most important ideas. Summaries are composed of verbatim excerpts presented in the same sequence as they appear in the original news source, with very minor editorial additions. Where material has been omitted between excerpts, the omission is indicated with ellipses (...). Any words added by an editor for clarity or context appear in [brackets]. Our original news editor was Fred Burks. Tod Fletcher edited most summaries from 2007 through 2014, and Mark Bailey has served as news editor since 2014.
