Solar updraft tower

The solar updraft tower is a proposed type of renewable-energy power plant. Air is heated in a very large circular greenhouse-like structure, and the resulting convection causes the air to rise and escape through a tall tower. The moving air drives turbines, which produce electricity. A research prototype operated in Spain in the 1980s.

Study reveals new, cost-efficient method for creating portable hydrogen fuel cells

A new paper published in Journal of the American Ceramic Society proposes a new method of producing hydrogen for portable fuel cells. This new method negates the need for the complicated and expensive equipment currently used. With their ability to work steadily for 10-20 times the length of equivalently sized Lithium-ion batteries, portable fuel cells are ideal energy suppliers for devices such as computers, cell phones and hybrid vehicles.

UCLA chemists design world's lowest-density crystals for use in clean energy

Chemists at UCLA have designed new organic structures for the storage of voluminous amounts of gases for use in alternative energy technologies. The research, to be published on April 13 in the journal Science, demonstrates how the design principles of reticular chemistry have been used to create three-dimensional covalent organic frameworks, which are entirely constructed from strong covalent bonds and have high thermal stability, high surface areas and extremely low densities.

Cellulosic ethanol: Fuel of the future?

In his Jan. 23 State of the Union address, President George Bush outlined his plan to reduce the nation's dependency on foreign oil by requiring the production of 35 billion gallons a year of renewable and alternative fuels by 2017, roughly five times the current target set by Congress of 7.5 billion gallons by 2012. Among the most promising alternatives are fuels derived from biological material. Currently, the main biofuel used in the United States is ethanol distilled from kernels of corn. There are about 140 corn ethanol refineries nationwide, which produce more than 5 billion gallons a year. But critics say that corn ethanol alone won't meet the president's goal of 35 billion gallons of alternative fuels in 10 years, because cultivating corn to use only its grain would take up too much land. According to the National Environmental Trust, producing 35 billion gallons of ethanol annually would require putting an additional 129,000 square miles of farmland—an area roughly the combined size of Kansas and Iowa—into corn production.

University of Nevada professor demonstrates new hydrogen fuel system

Northern Nevada energy consumers can be excused if they have a sense of "sticker shock" when their power bills come due following the holiday season. Or, that they have a feeling of powerlessness as the price of gasoline climbs to $3 per gallon.

Canary Island to be powered solely by renewables

El Hierro, one of the smallest of Spain's Canary Islands, is changing to 100 per cent renewable energy by harnessing the power of wind and water.

Children and young people show elevated leukaemia rates near nuclear facilities, says multi-study review

Leukaemia rates in children and young people are elevated near nuclear facilities, but no clear explanation exists to explain the rise, according to a research review published in the July issue of European Journal of Cancer Care. Researchers at the Medical University of South Carolina carried out a sophisticated meta-analysis of 17 research papers covering 136 nuclear sites in the UK, Canada, France, the USA, Germany, Japan and Spain.

New developments in 'artificial photosynthesis'

Scientists at Brookhaven National Laboratory are trying to design catalysts inspired by photosynthesis, the process by which green plants convert sunlight, water, and carbon dioxide into oxygen and carbohydrates. The goal is to design a system that can produce methanol, methane, and hydrogen directly from water and carbon dioxide using renewable solar energy. Four Brookhaven chemists will discuss their research on this "artificial photosynthesis" at the 233rd National Meeting of the American Chemical Society.

New 'biofuel cell' produces electricity from hydrogen in plain air

A pioneering "biofuel cell" that produces electricity from small amounts of hydrogen mixed in ordinary offers significant potential as an inexpensive and renewable alternative to the costly platinum-based fuel cells that have dominated discussion about the "hydrogen economy" of the future. The work will be described at the March national meeting of the American Chemical Society in Chicago.
