The beauty of a MIDGE stove is the ease of fuelling as well as the ease of operation. What could be easier than picking up dead twigs, burning them and making a meal?
Although a MIDGE stove will run on broken twigs you can pack more wood (and hence heat) into a MIDGE stove by chipping the wood beforehand.
To that end a garden shredder is used. Simply feed dead branches and twigs into the shredder and bag the chips until they are needed. Do not bag chipped green wood as this will rot. Green chips can be left out in the sun under a plastic sheet to bake in the sun. Leave a gap under the sheet for moisture to evaporate.
