It is a very well-known, sometimes even unfortunate, fact that people who care about nature and the environment, are considered let’s say different. Thankfully, in the last few years we notice an increasing tendency towards taking better care and...
Platinum is undoubtedly quite an expensive element to use as a catalyst in hydrogen fuel cells. For that reason, scientists at Brown University are trying to find a cheaper material that can act in this same way and be...
Despite the influence of misleading media reports on global warming issue as fraud and exaggerated, the Americans are back to believing that it is actually happening and climate change it brings is afflicting people now.
In 2008, 71% of Americans,...
The Stirling engine generator Dean Kamen invented is small and quiet enough to be put just about anywhere, and is extremely efficient, running on a number of readily-available fuels.
The Society of Cable Telecommunications Engineers Cable-Tec Expo finished today in...
Researchers from Yale and New York University recently completed a study of solar installations in California, covering January 2001 to December 2011. What they found might not be particularly shocking, but according to the study released in Marketing...
Currently, power grids are very centralized and electricity is produced on demand. This also makes the power grid very susceptible to interruptions due to storms or accidents, or simply excessive demand. Recently, smart grid technologies have been helping to...
Typical white light-emitting diodes are extremely bright and expensive to manufacture. Their applications are also limited because of the directional nature of the light they produce. Japanese researchers have developed a new white LED, using a different phosphor...
With lithium batteries being the most desirable mean for powering devices, it is inevitable that their main disadvantage is highlighted. The element that powers them is considerably expensive and it is expected that the price will rise with the...
In the midst of a city where air pollutants are lingering, along the Cermak Road and the Blue Island Avenue, stands the two-mile stretch of a street paved with photocatalytic cement that removes nitrogen oxide from surrounding air.
It is...
The typical internal-combustion engine is no more than 30% thermodynamically efficient, that is, only about 30% of the energy in the fuel actually does any work propelling the vehicle. The rest is lost to heat and friction, which...
