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 hogs 1. Better insulation 2 can make refrigerators much more efficient. And a panel encasing a vacuum is one of the best insulators 3 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 leftover 4 husks from processing rice are burned for energy and the ash remains 5. It's high in silicon 6 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 swapping 7 them into the refrigerators could lead to about a 50% energy savings 8. 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.
