(Rinnovabili.it) – The apple world's most famous computer seems to have set his sights on wind technology. And in style Apple, the chosen approach is innovative and unprecedented. It was revealed by the US Patent and Trademark Office which these days has made public one of the patents filed in 2011 by the Cupertino company. Specifically, the patent covers the design of an on-demand system to harness the energy of the wind and allow you to optimize the productivity of wind farms getting electricity even in the absence of wind. The system imagined by engineers of Apple abandons the old approcciovento = electricity and, on the contrary, foresees to store the energy of rotation of the blades in the wind rotor in the form of heat through the use of a fluid with low heat capacity. The fluid in question, stored in a thermally insulated container, is ready to give its heat when energy demand to a working fluid (working fluid) Finally, the system would use the steam emerged from the working fluid to generate electricity to be introduced immediately in network. According to the patent application, the project can reduce costs associated with natural variations of the wind. In addition, the method can be used as a substitute to the existing energy storage systems such as lithium-ion batteries or hydroelectric plants to pumping.
