A Molten Salt Solar Plant, Sounds strange doesn’t it? It sounds complex but it’s actually quite simple. It’s aim is to continue producing energy, well into the night. A solar tower will be built in Nevada, costing tax payers all of US$737 million. The tower will be filled with molten salt and this salt will be heated to 1,050 degrees Fahrenheit. The salt will retain its thermal energy for a very long time and can be mixed with water to produce to steam at anytime. Unlike water, molten salt retains heat for an extended amount of time, allowing the generator to potentially work for up to 12 hrs after the sun has set. The reasons behind using molten salt is because it is liquid at atmospheric temperature, it is cost efficient because salt is readily available as a natural resource and it is non-flammable and non-toxic.
We’re building for the future and it looks good at the moment but have we started too late?
