Solar Panels combined with Melted Salts lead to a maximum capacity of Solar Energy Storage

As you can see from the last posts you may realize that I am one of those people that support the development of solar systems and try to make "light"in each project of this kind.In solar panels field, researchers have discovered a new technology that is combined with mineral salts, melted salts that could lead to some more advanced solar systems more effective.This new system is based on some mirrors attached in circles that have in the middle of them a reflector.Inside it this reflector has salts, which can reach a high temperature and then are transmitted to a turbine that produces electricity (used salts: potassium nitrate and sodium). Such systems have been used before, but their advantage is that cause replacement water with those salts could lead to a temperature of aproximately 390 degrees.This receptor is situated at the same level with the earth and the size of this receptor would reach a maximum limit(no size limit).Those solar systems are already available in stores from Spain and the researchers say that are much cheaper than other solar panels.
