nano-spike CO2 ethanol

Converting CO2 (+ water + electricity) into ethanol fuel by "nano-spike" catalysis!

Nano-Spike catalysis; discovery of the Oak Ridge National Laboratory made a bit… by chance! The process makes it possible to obtain ethanol from CO2, electricity and water in the presence of a specific nano-catalyst called Nano-Spike. The announced yield on electricity is 60 to 70% which is acceptable on condition that renewable electricity is used (the process […]

Permafrost or permafrost

Warming: Permafrost at Risk Up to 90% of the permafrost in the polar regions of Canada, Russia and Alaska could disappear by 2100 due to global warming, much sooner, in fact, than the researchers have so far predicted. This is what a study by the American research center reveals […]

The Greenhouse Effect: Are we going to change the climate?

by Hervé Le Treut, Jean-Marc Jancovici Flammarion, 2004 Summary: Since the appearance of life, man is the first species able to upset the climatic conditions reigning on Earth. In less than a century, the increase in the greenhouse effect, a consequence of the increasing use of energy, is likely to cause unprecedented warming of […]

Runaway warming

Report broadcast on the 13pm news from France2 on November 30, 2005. Keywords: global warming, consequence, soils, environment, runaway The report evokes the worrying release of CO2 by peatlands. Indeed; a study showed that the soil currently emits twice as much CO2 as it did 25 years ago. In other words […]

The ecosystems and global warming

The sensitivity of ecosystems to global change Key words: climate change, biodiversity, species, threat, studies A study carried out by several European laboratories, including the Alpine Ecology Laboratory (CNRS - Université Grenoble 1 - Université Chambery), shows that the sensitivity of ecosystems to global changes could increase the vulnerability of certain European regions by […]
