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 […]


Energy transition: Portugal powered for 4 days entirely with renewable electricity!

While France continues to bet (almost) everything on nuclear electricity… countries are currently breaking records for renewable electricity production! This month it's Portugal's turn to achieve a real tour de force of renewable energy! A few days after Germany produced so much renewable electricity that producers […]

climate risks and threats of nuclear war

By Viktor Danilov-Danilian, Director of the Institute of Water Problems of the Russian Academy of Sciences, for RIA Novosti Climate change on our planet is becoming less and less predictable. The losses caused by abnormal heat waves, floods, droughts, hurricanes and tornadoes are constantly being calculated. According to the ministry […]

Cool Earth to fight against global warming?

Our planet Earth soon to be air-conditioned? by Joëlle Pénochet To find out more and discuss: cooling the earth against global warming and climate change with global geoengineering: fiction or reality? All the important studies published recently predict that climate change - announced more than thirty years ago by several official reports, personalities […]

Download: Report on Urban Transport: energy and organization

Technological Research Project carried out by Christophe Martz at ENSAIS and supported at the end of January 2001. This is a study on the congestion of urban centers and making an inventory of the different technological solutions that could improve air quality and traffic conditions in urban centers. Unanimous conclusion: the organization and behavior of […]

Global energy consumption

What is the global consumption of primary energy, its evolution since the beginning of the industrial era and the different sources of energy used by humanity? The answers to these 3 questions are in the graph below (click on the image to enlarge): Evolution of “commercial” energy consumption in millions of tonnes of oil equivalent.

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 […]
