Las Vegas = solar electric power from molten salt
last year:
Las Vegas is such a city where night turns into day. The whole city is filled with colorful lights. To lit up the lights at night continuously, huge amount of electricity is spent. To keep the pressure on traditional electricity low, a developer of large-scale solar power projects named SolarReserve announced earlier this year that it has completed the central piece in its Crescent Dunes Solar Energy Project that can produce 110 megawatts of energy, and distribute the power among 75,000 homes.Large Solar Tower To Power Las Vegas recently: a short video on the power plant The Window: Generating Energy With Sunlight, Mirrors, and Molten Salt - Wired Science Salt can now heat the food that *some* people like to put the salt on, who would of thought it, besides the chemists..

I googled it to see what progress has been made. Quite a bite it seems. You never know with some of these projects. A lot seem to just get forgotten.

They aren't small mirrors either!

I was unsure of the verity of the story myself..but it is scheduled to be up and running later this year. These Solar electric Power generators are a game changer and rule breaker all with a simple manipulation of the resources , they were using their thinking caps when they devised them.
I imagine these units will soon be profitable , then attractive to the Corporations and investors alike. |

I can only imagine that coal is cheaper to build otherwise I think we would see tons of these things around. Has anyone seen/read a comparison on them? I know these type of solar plants have been around for a while now. I'm not sure why they aren't more prevalent.

Out of curiosity, does anyone know what type of salt is being used?
I wouldn't think it's sodium chloride. |

Salt n pepper
Table salt has good properties for this , oddly enough.
What is Molten Salt? Molten Salt is a rather dreadful name for an otherwise useful catagory of materials & processes. The term "Molten Salt" is self-descriptive; it is melted salt(s). Another common name is Fused Salt(s). The simplest example of a molten salt would be to take sodium chloride ("table salt") and heat it to a red heat (greater than 801° C, or 1474° F)1 where it would melt into a liquid. This liquid is stable, has a heat capacity similar to water (by volume) and flows much like water does. The major differences are the obvious higher temperatures attainable in the molten salt state and when the salt solidifies (freezes) it contracts versus expanding like water. Thus, molten salt freezing in a pipe would not burst the pipe as water would. Salts are simple, usually ionic (that is the chemical bonds are a simple ionic type) and stable compounds. The most common example of which is "table salt", or sodium chloride (NaCl). Both sodium and chlorine are notoriously reactive; sodium is one of the most electropositive substances (wants to lose an electron) & chlorine one of the most electronegative (wants to take an electron). These two opposite substances readily join to form stable sodium chloride via a strong ionic bond. The melting point of sodium chloride is 801° C ( 1474° F )2, at which point it becomes a liquid, and thus a "molten salt".
