  •  Awesome! But fundamental error in your figuring.. (0+ / 0-)

    ...I think that there are probably better sources for the feedstock than trees -- as the article said, the bed method can work well with wet green material, so why not use a crop that's more efficient at producing biomass per acre?  AFAIK trees are moderately poor at this.

    •  Output per acre ... (0+ / 0-)

      ... is a deceptive measurement of productivity for biomass, since there are differences in how productive different acres are in growing food crops.

      Also, the figures cited in the comment above are Oven Dried Tons, not wet weight, and 3-6 ODT is quite reasonable productivity compared to the perennial grasses and other prairie perennials that would be appropriate in grassland biomes.
