Molten Salt Solor Power Stations

One of the biggest problems, as everyone knows, with solar energy is the difficult off-times when the sun simply won’t shine (at night or during poor weather). To take advantage of even these down times systems like these that use materials (like salt) which store heat for long periods even in the absence of sun seem to be the next stage in solar energy evolution – making the absolute most out of available power and materials. What’s next on the solar horizon? Hard to say but the key elements seem to be: (a) using solar power even without the sun, (b) mixing solar power with other alternative energies and (c) making maximum use of solar power by integrating it with existing structures and vehicles at small and large scales with maximum material, time and cost efficiency.
