A team of MIT students recently tested a prototype of the "most cost-efficient solar-power system in the world."
Steam produced by dish exits hose.
They say it is simple, small, lightweight, made of parts that are cheap and available anywhere, and can melt steel bars. It can be built by nearly anyone.
Its inventor, Doug Wood says, "This is actually the most efficient solar collector in existence."
The collector is expected to be used later in large arrays, and hopefully help revolutionize global energy production.
