I’m shamelessly spreading this link around, because it’s one of the most interesting pieces I’ve read in a while: Engineer-Poet at his blog The Ergosphere has a detailed and fascinating exploration of the possibility of using charcoal (derived from biomass and wastes) to fuel America, with many, many charts and numbers for the wonkishly inclined.
The short version is: If we’re smart about it, we can generate enough electricity and liquid fuels from biomass in the United States to replace all fossil fuels and then some, plus rejuvenate long-suffering American soils, plus sequester billions of tons of CO2. Check it out here.
