Wind Explorer, a lightweight carbon fiber car powered by Li batteries and a portable wind turbine, recently traveled a whopping 3,000 miles across Australia with the assistance of wind power. The car used a portable wind turbine, Li-ion batteries and a giant kite that pulled the car when the wind is strong enough. The Li-ion batteries charged at night produces enough energy to travel 175 to 225 miles. The carbon fiber body with batteries and portable turbine weighs around 470 Lbs. With two average sized people,the Wind Explorer weights around 1,000 Lbs.
