Terra Preta Soils Technology To Master the Carbon Cycle

- erich

This technology represents the most comprehensive, low cost, and productive approach to long term stewardship and sustainability.Terra Preta Soils a process for Carbon Negative Bio fuels, massive Carbon sequestration, 1/3 Lower CH4 & N2O soil emissions, and 3X Fertility Too.

SCIAM Article May 15 07;

After many years of reviewing solutions to anthropogenic global warming (AGW) I believe this technology can manage Carbon for the greatest collective benefit at the lowest economic price, on vast scales. It just needs to be seen by ethical globally minded companies.

Could you please consider looking for a champion for this orphaned Terra Preta Carbon Soil Technology?

More About Wonderful Algae

- Adam Clare

I love how algae can be used for almost anything. If the future is covered in algae, well, I’ll be the first to say that that’s a good thing.

Inhabitat has a post about how algae is being converted into crude biofuel.

The scientists involved in the LiveFuels project are focusing on specialized aspects of the algae-to-biocrude process. Some are breeding algae to find the best high-fat strains, others are refining the fat and oil extraction process and others still are developing cost-effective harvesting techniques. The biggest challenge is to make algae biocrude within a fraction of the time that nature’s biomass decomposition occurs and to do it economically, for less than $60 a barrel.

More Efficient Jet Travel

- Adam Clare

Princeton University is looking into the details of using biofuels in jet airplanes. The research team will examine what fuel mixture provides the best efficiency and how engines can be designed to better burn the fuels that they are bound to create.

Alternative energy sources, if designed appropriately, also could significantly reduce the amount of greenhouse gasses released in creating and burning jet fuel. According to the U.S. Department of Transportation, aviation is responsible for around 10 percent of the greenhouse gas emissions from transportation in the nation, or roughly 2.7 percent of the country’s total greenhouse gas emissions. The second research program, supported by NetJets, augments Dryer’s fundamental MURI work and brings in additional expertise from the Princeton Environmental Institute to develop “greener” alternative fuels.

Negative Carbon Output

- Adam Clare

Terra preta is apparently wonderful and will help us fight climate change. World Changing has a great post about the human made fertilizer that will probably answer all your questions about terra preta.

Because terra preta locks so much carbon in the soil, it’s also a form of carbon sequestration that doesn’t involve bizarre heroics like pumping CO2 down old mine shafts. What’s more, it may reduce other greenhouse gases as well as water pollution: according to Biopact, a network that promotes biofuels and biomass energy…

Algae is Gooey Power

- Adam Clare

I’m always impressed by what algae can do. It can be used to generate electricity, make us healthier, it can function as a biofuel, and can be used to clean the air. Algae can almost solve all the worlds problems!

Some enterprising researchers have found out that algae can also be tweaked to create a lot of hydrogen. Hydrogen produced by algae can then be used as a power source elsewhere.

Melis has created mutant algae that make better use of sunlight than their natural cousins do. This could increase the hydrogen that the algae produce by a factor of three. It would also boost the algae’s production of oil for biofuels.

The new finding will be important in maximizing the production of hydrogen in large-scale, commercial bioreactors. In a laboratory, Melis says, “[we make] low-density cultures and have thin bottles so that light penetrates from all sides.” Because of this, the cells use all the light falling on them. But in a commercial bioreactor, where dense algae cultures would be spread out in open ponds under the sun, the top layers of algae absorb all the sunlight but can only use a fraction of it.
