Use of fuel cells is an alternate energy technology that is being studied for full-scale implementation. These can be classified into three subgroups: catalytic, enzymatic, and microbial. Microbial fuel cells are unique in their ability to utilize microorganisms, rather than an enzyme or inorganic molecule, as catalysts for converting the chemical energy of feedstock directly into electricity.

The long-awaited "smart grid" for U.S. power could play a major role in rolling out renewable energy like wind and solar, the top U.S. power regulator said on Wednesday.

The European Union's executive will next month publish its strategy for promoting hi-tech solutions to climate change, aiming to give European businesses a head start as the world switches to low-carbon energy.

A draft document obtained by Reuters gives insight into the European Commission's priorities.

A bacterium can generate electricity from mud and waste fuel cells which use microorganisms to convert chemical energy to electrical energy are seen as one of the future sources of clean power. But the capacity of such cells to generate electricity is very low. Researchers knew of microbes that can extract electricity from mud and wastewater. They have now found a way by which

Honda Motor Co will maintain the target for lease sales of its newest fuel-cell car after over a year since its launch despite the challenge of boosting productivity, the model's chief engineer said.

There are certain technology challenges which have waited in vain over several decades for a satisfactory solution. The economical storage of electricity is one of them. But intensive work in the meantime is driving advances along various avenues.

health Cracking the capsule Every year a million people, mostly aids and transplant patients, are killed by a disease called cryptococcosis, symptoms of which include chest pain, dry cough, abdominal swelling, headache and blurred vision. This disease is caused by the deadly fungus Cryptococcus neoformans which attacks immune systems that are already infected. Researchers have

The Fukuoka prefectural government said Tuesday it will start an experiment using fuel cells at 150 households in two housing complexes, which it claims will be the world's first example of setting up household fuel cell systems on such a scale, with 100 units in a single concentrated area. The experiment is aimed at proving the practicality of using environmentally-friendly household fuel cells for supplying electric power and heat, the prefecture said, noting that the experiment will be conducted jointly along with Nippon Oil Corp and Saibu Gas Energy Co. A single unit of the system will be able to cover about 60% of power supply needs and about 80% of hot water needs of an ordinary household, resulting in a reduction of energy consumption of roughly 30%, according to the prefecture.

Automakers are realising the advantages of four stroke engines. But fuel cells and electric vehicles remain the industry s orphans

Despite being clean, alternative fuels fail to become the first choice
