Salt, not batteries, is the solution to our energy storage needs

In the desert of Nevada stands the most advanced solar power plant in the world that has solved the greatest predicament that comes with harnessing the power of the sun: energy storage. Within a tower surrounded by ten thousand silvery glass panes is a mixture of potassium and sodium nitrate that is heated to unforgiving temperatures by the concentrated sunlight reflecting off the panes. When the potassium-sodium concoction, also known as molten-salt, reaches 560°C, it  is stored in large tanks that maintain the heat efficiently. From there it can be converted into electricity through a conventional steam turbine. The solar power plant in Nevada is only a mile-and-a-half wide, and yet it can power 75,000 homes even when the sun goes down.
