Recently, after a three-week adventure, they managed to complete their task, spending only under $16.
Their vehicle, called Wind Explorer, is the world’s first self-sufficient wind-powered car. It includes lithium-ion batteries that can be charged overnight using a mobile wind turbine.
Wind Explorer can travel 100 kilometers and spend about 50 percent the electricity that a washing machine would spend.
In addition, the car weights around 200 kilograms (440 pounds) and can reach a top speed of 88.5kph. About 80 kilograms is the weight of the batteries. By using kites, the vehicle can generate additional wind power.
It is worth mentioning that Wind Explorer became the world’s first wind-powered vehicle to cross a continent.
