Hello --



Some other biomass related numbers:



28x106 btu/person-year = 1/10 of the annual per person energy consumption in
the US = approximate world annual average energy consumption.



Growing leucaena at 38 dry-ton/year produces 307x106 btu/hectare-year.
Using the average annual energy consumption per hectare, this energy would
satisfy the total consumption of 11 persons/hectare-year.  See,
www.CorpFutRes.com



The Brazilian State of Minas Gerais has an area of 588 000 km2  = 58,800,000
hectares.  Estimating that 30% of Minas could be planted in leucaena, or an
equivalent giant legume, the total productive area available would
be17,600,000 hectares that, when multiplied by the annual energy consumed
by11 persons -- would provide the annual energy for 193 million
Brazilians -- the approximate Brazilian population.



Furthermore, the co-product of CFR's process, an anaerobic compost produced
in immense quantities under the given assumptions, provides for
sequestration of atmospheric carbon dioxide beyond providing an outstanding
agricultural fertilizer.



These assumptions would not involve destruction of ecologically sensitive
lands, but the use of lands previously used or otherwise available for
agricultural purposes -- and Minas' area is less than 1/4 of what may be
available in Brazil -- outside of the Amazon Region -- for energy-fertilizer
agriculture.
