Norbert: cc Alex and list

	I'd still like to kick around the "short log" idea and other char-making possibilities.  But Alex' suggestion earlier today has much more merit -  I wish I had thought of it.  I've never liked that "retort" approach for cookstoves, since there is close to zero capability to control power levels.  But that is not important for your type of space heating.  Could lower costs and produce considerable char relatively easily.  I also like Alex mentioning the availability of H2 - what you want for cleaner heating we don't want in char.

Getting a load from the woodshed and stacking it in the heater would be very different. It would be an interesting experiment to try, maybe we'll try a load like that in our lab this winter, just to see how it burns. I'd guess it would need some kind of basket in the firebox, so that you could get air all around it. There are, for example, pellet baskets that you can use in a regular stove or fireplace:
