Mushroom Insulation?!?

In the growing "green" movement, developments are happening quickly.  One of these seems to hold considerable promise: insulation (and packing materials) that aren't manufactured, but rather grown.  Two young entrepreneurs, Eben Bayer and Gavin McIntyre, have developed a strong, low-cost biomaterial that uses fungal mycelia and agricultural cast-offs like seed husks; a cubic inch of the stuff contains eight miles of mycelium fibres.  Intended to replace styrofoam and similar petro-based products, the production of their material creates no carbon, consumes little energy, and it can be composted away when disposed.  They've formed a company called Ecovative Design, headquartered in Green Island, New York, to produce it,  Check them out at www.ecovativedesign.com.
