Solar ‘Sponge’ Generates Steam From Sunlight

No, that is not a graphite hamburger. Solar power meets steam on a small scale — with a surprisingly wide number of applications! Here is some way cool science, courtesy Think Progress.

Researchers at the Massachusetts Institute of Technology unveiled a new material this week that provides a highly efficient way to convert sunlight into steam and holds major potential for improving technologies like desalination of water and solar thermal power — all with a four-inch graphite ‘sponge.’

The setup developed by MIT consists of a layer of graphite flakes and carbon foam beneath that. It’s porous, which enables the disc to float on water, and the dark color of the graphite attracts maximum energy from the sun.

The end result is a system that converts 85 percent of incoming solar energy into steam — far more efficient than previous methods. “Basically, if you heat up the whole volume of the water, you don’t raise the temperature very much,” Gang Chen, a professor of mechanical engineering at MIT, told ThinkProgress. “However, if you only heat up a small amount of water, then the temperature rise could be high.”

    Sounds like a great thing for a lot of people. Anywhere in the third world where water quality is questionable this would be great. Here in America it would be great on camping trips and people who have well water that is questionable. I hope something makes it to market soon that is affordable for the average person.

    Now let’s see ya do it without the water, smarty pants.

    Not to nitpick [laughing], but this actually generates steam (H2O in it’s gaseous state) from water, using solar energy to heat it. Nevertheless, pretty cool stuff.
