The Tidal Irrigation and Electrical System

A rather nice idea was proposed by Texas based, LiveFuels, Inc. Well, it has the potential to be a nice idea. It could be absolutely horrible. They intend to create optimum algae growth in a a 45 acre saltwater pond on the Texas coast by introducing agricultural waste. Fish would be introduced into the ponds [...]

The Royal Society’s report on geoengineering schemes was a disappointment. In it’s analysis of different ideas to mitigate greenhouse gasses in the atmosphere it focused on only part of the problem. Right at the beginning of the report it says that it will focus on schemes that divert solar energy into space or absorb CO2 [...]

Recently, I submitted the TIE System for assessment by the Royal Society’s working group on geoengineering schemes to mitigate climate change. (http://royalsociety.org/news.asp?id=8085) In the process I have been looking at a few other ideas. Many of them, like increasing the albedo of marine stratocumulus clouds and shading the earth with a large group of small [...]

The concept of peak oil does not only encompass the end of cheap fuel for transport, it also spells the end of cheap food and water. 
By the late 18th century, minds were already turning to the problems of too many mouths to feed given the agricultural technology of the time. Malthusian predictions of population crash [...]

Researchers at the Helmholtz Association of German Research Centres and Caltec have successfully captured syntrophic microorganisms. These creatures consume methane and normally live in the anaerobic conditions in marine sediments existing in complex microbial ecosystems. It has been very difficult to separate the individual Archaea that were responsible for the anaerobic oxidation of methane because they do [...]

One method of lowering atmospheric carbon dioxide through the growing of algae in the ocean is by adding powdered iron to the surface. The iron acts as a fertilizer and the algae that blooms absorbs the carbon dioxide in the building of its tissues. However, the consequences of sudden jolts of nutrients due to fertilizer being [...]
