Yes. This fits in my program. We are currently using rice hull as an alternative source of energy and to make the rice value-chain more sustainable.

Yes

You can also use leaves from the trees that fall and dry out and old newspapers cut up into small pieces then mix with water untill they turn into an oatmeal looking substance. You then fill a small two foot piece of 4" PVC pipe and fill it with the substance untill it dries. Push it out and you get a log looking cyclider. They burn longer than logs, smell like wood, and clean for the enviroment.
