Electric Sail Powered By Solar Wind
By Nick April 22, 2008
Solar wind is a plasma stream which is radiated continuously by the Sun and the changes of their properties cause auroral brightening and magnetic storms. The solar wind helps electric sails to move around which means that these electric sails don’t need any other type of fuel.
The developer of this fuel-free electric sail if Dr. Pekka Janhunen from the Finnish Meteorological Institute and this invention could revolutionize the movement across space. These devices consist of long metallic tethers and a electron gun powered by the Sun.
According to Dr. Janhunen, his team didn’t “encountered major problems in any of the technical fields thus far” and he also added that the will begin testing in the near future and the researchers are sure that this technology is cheaper and it can lead to a faster space exploration.
