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 is burned for energy, and the ash remains 5. It’s high in silica and carbon. So they tinkered with the ash and developed a new core material for vacuum insulated panels. It’s about 50 percent cheaper than what’s currently available. And the resulting panels are such good insulators that swapping 6 them into refrigerators could lead to about a 50 percent energy savings 7. They’re 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. Which will be invested in further research and development.
