Mushrooms - the great insulator?

Mushrooms could soon be used to insulate homes. That's right. An American company has invented a pioneering product called (not very inventively) "Greensulation".

The product is currently undergoing testing, but its makers say it could potentially hit the market as soon as 2010.
These chaps have produced an insulator using our friend the mushroom - plus rice hulls and recycled paper. When mixed together with water and hydrogen peroxide, placed in plastic containers and put in a dark place it then literally grows into shape.

So now not only can you insulate yourself against the cold with a piping hot bowl of wild mushroom soup - you can put the stuff into your homes and keep the whole family warm!
