This is Scientific American 60-Second Science. I'm Cynthia Graber. This will just take a minute.

The fridge is one of your home's biggest energy hogs1. Better insulation2 can make refrigerators much more efficient. And a panel encasing a vacuum is one of the best insulators3 known. But vacuum-insulated panels are too pricy for widespread use.

Enter some University of Michigan students, they took something called rice husk ash, the leftover4 husks from processing rice are burned for energy and the ash remains5. It's high in silicon6 and carbon. So they tinkered with the ash and developed a new core material for vacuum-insulated panels. It's about 50% cheaper than what’s currently available. And the resulting panels are such good insulators that swapping7 them into the refrigerators could lead to about a 50% energy savings8. Their space efficient too, a one-inch-thick ash panel equals today’s four-inch-thick polystyrene panels.

Then Michigan Business students partnered with the scientists to create a company called Husk Insulation. They entered the invention in the M.I.T Clean Energy Prize Competition. And on May 13th, Husk Insulation won the competition's first prize, a cool 200,000 dollars, which will be invested in further research and development.

Thanks for the minute. For Scientific American 60-Second Science, I'm Cynthia Graber.
