Scientists at the University of Georgia have discovered a new way to grow molecular wire brushes that conduct electrical charges. According to the researchers, this discovery is the first step in developing fuel cells for devices such as cochlear implants, prosthetic limbs and pacemakers.
Highly efficient hydrogen fuel cells are wanted due to the high price the existing ones have so far. So, being efficient means less money spent on them, and more market share for hydrogen. SOFCs (solid oxide fuel cell) are a type of hydrogen fuel cell that use solid (not liquid) electrolyte to do their job, while being much more efficient.
Sainsbury's, from Gloucester, UK, is the first supermarket to use the kinetic energy coming from the cars entering their parking lot to (partially) power their shop.
A recent study reveals shocking figures telling that, basically, traveling by train pollutes the environment more than traveling by airplane. How can that be?
Dr. Ken Shih and some of his physicist colleagues, have reported the development of the thinnest superconducting metal layer ever created, a superconducting sheet of lead only two atoms thick.
Scientists from Southern California Edison (SCE) have developed an tested for two and a half years a lithium-ion battery sub-pack with very encouraging results. The battery tested survived 180,000miles with no significant deterioration.
Cargo boats are among the most polluting things on Earth after cars. Most of them have no emission control and do not obey regulations put in place only a few years ago. Because their value is huge and their profits are enormous, only unobtrusive green thinking can change the way they travel and pollute the air.
Passivhaus is a German concept of a home that needs very little heating or cooling, because it is so well insulated that it could basically be built on martian surface. There are more then 20,000 of these Passivhaus homes worldwide, many of them being buildings, kindergartens and office spaces.
Using big things to create electricity is generally good - but not always. Big things tend to be inefficient, hard to handle and to install. Wind turbines are just the case of this example - if they are too big, they are too noisy and insensitive to slow winds - that leads to inefficiency in all related aspects.
For many people from urban areas the access to potable water is very low. To combat the water crisis, scientists had to design systems that can help provide clean drinking water from something that is omnipresent.
