Sun-powered aircraft to support sustainable development
Swiss adventurer Bertrand Piccard is constructing a solar-powered plane to fly around the world. His aim is to support sustainable development by demonstrating what renewable energy and new technologies can achieve. ESA is assisting by making available European space technologies and expertise through its Technology Transfer Programme.
Bertrand Piccard made the first non-stop around the world balloon-flight in a Breitling Orbiter in 1999 with Brian Jones from Britain. Now togeth
Ethanol and biodiesel from crops not worth the energy
Turning plants such as corn, soybeans and sunflowers into fuel uses much more energy than the resulting ethanol or biodiesel generates, according to a new Cornell University and University of California-Berkeley study.
“There is just no energy benefit to using plant biomass for liquid fuel,” says David Pimentel, professor of ecology and agriculture at Cornell. “These strategies are not sustainable.”
Pimentel and Tad W. Patzek, professor of civil and environmental eng
Fuel ethanol cannot alleviate US dependence on petroleum
A new study of the carbon dioxide emissions, cropland area requirements, and other environmental consequences of growing corn and sugarcane to produce fuel ethanol indicates that the “direct and indirect environmental impacts of growing, harvesting, and converting biomass to ethanol far exceed any value in developing this energy resource on a large scale.” The study, published in the July 2005 issue of BioScience, the journal of the American Institute of Biological Sciences (AIBS), uses the “eco
Sunshine mapping from space means brighter solar energy future
How sunny is it outside right now – not just locally but all across Europe and Africa? Answering this question is at the heart of many weather-related business activities: solar power and the wider energy sector, architecture and construction, tourism, even health care. Today accurate and continent-wide scale measurements of ground radiances are provided every 15 minutes by ESA’s Meteosat Second Generation satellite.
Integrating this information with the business practices of solar
Researchers create first nanofluidic transistor, the basis of future chemical processors
University of California, Berkeley, researchers have invented a variation on the standard electronic transistor, creating the first “nanofluidic” transistor that allows them to control the movement of ions through sub-microscopic, water-filled channels.
The researchers – a chemist and a mechanical engineer – predict that, just as the electronic transistor became the main component of microprocessors and integrated circuits, so will nanofluidic transistors anchor molecular pr
’Apollo Program’ for hydrogen energy needed
What if all the vehicles now on the road in the United States were suddenly powered by hydrogen fuel cells? Stanford researchers say in a June 24 article in the journal Science that such a conversion would improve air quality, health and climate–especially if wind were used to generate the electricity needed to split water and make hydrogen in a pollutionless process.
Similarly to how gas is pumped into tanks, hydrogen would be pumped into fuel cells, which rely on chemistry, not
