[Cob] suspicious embodied energy figures for lime

[Ron Becker]

Got this from a friend after a discussion about lime plaster vs 
portland based plaster. Anybody seen figrues lile these"

Ron

"The following figures, adapted from Adobe and Rammed Earth Buildings,
reflect the embodied energy in BTU's required for the production and
use of various materials. Soil block has a much lower embodied energy
than many traditional materials.

Portland Cement 94 lb sack 381,624 BTU
Lime, hydrated 100 lb sack 440,619 BTU
Common brick 1 block 13,570 BTU
Concrete block 1 block 29,018 BTU
Earth (Adobe) block (mechanized production) 1 block (10X4X14) 2,500 BTU"

Those who question global warming have a financial or emotional 
interest in the status quo.
