Actually, I think that wood pellets might be more of a "macro solution".

My wood burning experience has shown me that firewood use is closely tied to the type of stove. By that I mean that one uses wood which is cut to fit the particular stove. I would cut my wood into 20" slices, whereas my friend would cut his to mo more than 17" length. My neighbor wants his cut to less than 13". In short, there is no uniform size for firewood, no "one size fits all" as with fossil fuels. with oil, we have a few very clearly defined types, be it gasoline or diesel for transport, #2 heating oil for homes, kerosene or propane. These fuel divisions have allowed common technologies to evolve into highly refined systems. With firewood, a similar single type would be that found with pellet stoves.

BTW, pellets can be made from many biomass sources such as switchgrass, not just wood. Thus, pellet stoves might represent the best solution for the "one size fits all" problem.
