Akira Fujishima, thirty-five years ago, discovered the electrochemical properties of titanium dioxide. He showed that titanium dioxide functioned as a photocatalyst. It produced hydrogen gas from water, electricity and sunlight. Scientists are quite hopeful regarding the qualities of Titania (or titanium dioxide). This is also known as white pigment. It’s used in many products [...]
As soaring oil prices and greenhouse gas emissions fuel the search for cheaper and cleaner sources of energy, a Japanese aerospace manufacturer may have found the right stuff for a solution. It’s a windmill you can call your very own. Yokohama-based aerospace manufacturer, Nippi Corporation, has developed a revolutionary 20 kW wind turbine power [...]
Biomass fuel is liquid, solid, or gaseous fuel produced by conversion of biomass. They are actually organic materials produced by plants, animals, or microorganisms. Those plants animals or microorganisms can be burned directly as a heat source or they can be converted into a gaseous or liquid fuel. Scientists are looking to biomass for [...]
Scientists are continuously working on to find an alternative to fossil fuels. We are familiar with the side effects of fossil fuels and its impact on environment. Right now the fossil fuels seem to be necessary evil we can’t do without. Scientists want alternative fuels that have none of the ill effects of traditional [...]
When in distress we often look towards the heaven to find an answer to our problems. West coast energy giant, Pacific Gas and Electric (PG&E) is doing the same. They are heading towards heaven to trap the sources of renewable energy. This company’s main operations are in San Francisco and northern California. They are [...]
President Barack Obama is known as a staunch supporter of green energy. His stimulus plan has raised new hope for the environmentalists and economists alike. On the occasion of Earth Day, President Obama declared that developing renewable energy is crucial to America’s prosperity. He also declared that his administration will for the first time [...]
Scientists are constantly working on alternative energy sources to make its use widespread like fossil fuels. They are tirelessly working on the drawbacks of alternative energy sources so that they can be all pervasive like traditional sources of energy. Engineers at Oregon State University have found out a method to use an ancient life [...]
We often want to imitate nature for near perfect results. But sometimes it just remains a desire. In its quest for green and clean energy mankind is searching for that magical method that can split water into hydrogen and oxygen. Nature performs this task wonderfully through the process of photosynthesis. Man is still facing [...]
Environmentalists, common man, scientists, politicians, everyone want to breathe fresh and clean air and leave this earth in a better shape for next generation. Environmentalists and scientists are working to make this planet a better place to live. Hydrogen driven vehicles are a small step towards that goal. But the main hurdle to produce [...]
One of the main hurdles in the field of hydrogen car research is the development of a good fueling system. Professor Issam Mudawar along with his research team has developed a hydrogen storage system that would allow a car tank to be filled in five minutes and you can drive on that fuel for [...]
When we watch science fiction, deep in our heart many of us believe that’s how it will remain, a fiction. But few refuse to believe that and turn science fiction into reality. Angela Belcher and her team of bioengineers at the Massachusetts Institute of Technology (MIT) belong to the second category. They have turned [...]
It is great news that defense forces are promoting the use of alternative fuels in their own unique way. American army is using Unmanned Aerial Vehicles (UAVs) in Afghanistan. The greatest advantage of UAVs is that they are nearly untraceable from the ground. They are used heavily by defense forces in overseas missions when [...]
We all want to live in a clean and green world and breathe pollution free air. For this kind of environment we desperately need a fossil fuel free world. Scientists are toiling hard to come up with alternative fuels which can replace conventional fuels. One such study was presented at the 237th National Meeting [...]
A team of scientists at the Georgia Institute of Technology has developed a new treatment for silicon photovoltaic solar cells. This new method generates bumps and peaks on the surface that increase cell efficiency in two ways. The uneven surface protects the cells from water and dust. When water falls on the surface, it [...]
In the 237th National Meeting of the American Chemical Society (ACS) an interesting fact came to light that in near future we can recharge our cell phones or iPods by waving or stretching our arms, beating of your heart or going for a walk. We don’t need to plug-in our devices in a socket. [...]
If you secretly nurtured a dream of owning a flying car, the good news is your dream can be a reality by 2011. This month MIT students, from Department of Aeronautics and Astronautics, have successfully flight tested the prototype of a winged car for the first time. This car took off from a runway [...]
