Does anyone make a multi fuel or cross fuel stove insert? I've seen the free standing versions that burn everything and anything, corn cobs, nut shells, pellets, wood, ect. I think it would be neat to have a insert version of one of those stoves. Seems like if they could make them to look nicer they will be the stoves of the future. Flexible fuel options will allow you to burn whatever fuel is in least demand, and save heating costs.
