I read a article sometime ago about a factory that was coming to the outskirts of chattanooga tn. that was going to take the citys leaves and compress them into logs to heat with... I dont think it ever got started...?? also watched a little invention tv show where a guy took a hyd. splitter and made a thing to compress the leaves into a log... they did a little experiment and lit the leaf log and also had a wood fire going... the leaves burned at a higher temp than the wood.. not sure what the wood was... any of you ever made a leaf log??
