While solar power has been used to fuel motorcycles
, bicycles, ships, and airplanes, it seems that cars would be the most popular form of transportation of a solar vehicle around the world and researchers are trying to develop one for everyday public use. The Solartaxi, which was the result of a project in Switzerland, has actually circumnavigated the world as it drove 50,000 kilometres in 18 and crossed 40 countries. It can travel 400 kilometres without recharging. And has a maximum speed of 90 kilometres per hour. While this is positive news, it seems a type of solar-powered hybrid car will be the next step. However, it has been reported that the 2010 Toyota Prius will have an option to erect solar panels on its roof and that Toyota is trying to develop an all-solar car.
