MUSHROOM INSULATION
by Jorge Chapa
Just when you thought mushrooms were only useful as culinary garnishes (or maybe hallucinogenics as well), Gavin McIntyre and Eben Bayer, two students from the Rensselaer Polytechnic Institute have found a more noble purpose for the functional fungi- building insulation made from oyster mushrooms.
Greensulate is a fire-retardant board made out of water, flour, perlite, and mushroom spores. The idea came from an assignment which asked that they produce a form of sustainable insulation. The insulation material is grown by pouring the ingredients into 7 by 7 inch molds with hydrogen peroxide. When this mixture is placed in a dark environment, the mushroom oyster cells start to grow into a 1 inch thick panel, which is then dried to prevent fungus from growing. The pair have a working prototype, which in true college fashion, was grown under their beds.
“I think it has a lot of potential, and it could make a big difference in people’s lives,” said RPI Professor Burt Swersy, whose Inventor’s Studio course inspired the product’s creation. “It’s sustainable, and enviro-friendly, it’s not based on petrochemicals and doesn’t require much energy or cost to make it.”

I talked about this the other day as well in a new inventions post I was doing. This looks to be some really amazing stuff. The guys say it’s just as good as anything on the market today and maybe even better than some of your lower grade insulations.
