Also Try Algae Biochar Papers -Algae-Coated Buildings Touted as Climate Fix (CNet.com) "Engineers envision that long plastic tubes, called photobioreactors, be integrated into building designs or retrofitted onto existing skyscrapers. Algae would grow from pumped-in carbon dioxide and sunlight and be harvested for use either as a liquid fuel to run in a combined heat-and-power unit or turned into biochar, or charcoal used as a soil conditioner that also sequesters carbon from the air." "Finally, the institution says that buildings should be retrofitted with reflective roofs to deflect the sun's rays. In the past months, U.S. Energy Secretary Steven Chu has publicly touted this relatively low-tech approach, which was studied in-depth at the Lawrence Livermore Laboratory last year." 09-09 Cool Roof (Wikipedia.org) "In the world of industrial and commercial buildings, a roofing system that can deliver high solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the building) and high thermal emittance (the ability to release a large percentage of absorbed, or non-reflected solar energy) is a cool roof. Most cool roofs are white or other light colors." 09-09 Geoengineering (Wikipedia.org) "The modern concept of geoengineering is usually taken to mean proposals to deliberately manipulate the Earth's climate to counteract the effects of global warming from greenhouse gas emissions. The National Academy of Sciences defined geoengineering as 'options that would involve large-scale engineering of our environment in order to combat or counteract the effects of changes in atmospheric chemistry.' " [1] "Some geoengineering techniques are based on carbon sequestration." "Typically, the scientists and engineers proposing geoengineering strategies do not suggest that they are an alternative to emissions control, but rather an accompanying strategy.[3]" 09-09 Geoengineering Conclusions (ScienceDaily.com) "Key findings include: -Enhancing carbon sinks could bring CO2 back to its pre-industrial level, but not before 2100 – and only when combined with strong mitigation of CO2 emissions -Stratospheric aerosol injections and sunshades in space have by far the greatest potential to cool the climate by 2050 - but also carry the greatest risk -Surprisingly, existing activities that add phosphorous to the ocean may have greater long-term carbon sequestration potential than deliberately adding iron or nitrogen -On land, sequestering carbon in new forests and as ‘bio-char’ (charcoal added back to the soil) have greater short-term cooling potential than ocean fertilisation." 09-09
