Green bird People have been forced to rethink their preconceptions about the power of wind as, last month, a wind powered vehicle not only travelled four times the speed of wind, but in doing so broke the world record for the fastest moving human on the planet. In a craft called the Green Bird, Richard Jenkins clocked 126.1 mph on a dry lake in Nevada. So whilst there may be some buzz in the news today about the pros and cons of electric cars, it is clear that some people are thinking way ahead of these issues and are exploring technology that could be even greener.
