Alternative Energy

Presently Fluid Dynamics Expert, John Dabiri, is very much on the quest of improving designs of wind turbines. Spotting behaviours that may throw light on energy-related practices in biological system and trying to implement that in real-life situations is part of that quest and Mr.Dabiri is jubilant that he is learning lessons from a [...]

The NASA Research Program ‘N+3′ has thrown open a challenge for exploring the potential to develop quieter subsonic commercial planes as well as supersonic commercial aircraft that burn less fuel and pollute less. The team led by MIT are working on developing two models to meet the NASA criteria as well to [...]

EU’s ‘Clean Sky’ – the 1-6 billion euro research project – with 86 participating partners from 16 nations – has goals like developing unique application-specific technologies and evaluation and advancement of the entire aeronautic system. Aviation experts from ACARE (Advisory Council for Aeronautics Research in Europe) are expecting to achieve 50% reduction of noise [...]

In a market-friendly scenario, Nanosolar claims to be able to produce electricity at 5-6 cents/kilowatt hour almost as cheap as power from coal and at about one-third the cost of other solar power. Nanosolar claims: Nanosolar claims mass production of solar power will now become feasible with their differently manufactured solar panels. Conventional silicon-made [...]

We love the idea of clean and green fuel. But they come with certain disadvantages. First one is they are heavy on pocket of a commoner. Second disadvantage is their power conversion rate is quite low. Last one is you need storage space to save all the power converted by a clean and green [...]

A research company in New Hampshire recently patented its bladeless wind turbine, which is based on a patent issued to Nikola Tesla in 1913. This wind turbine is christened as the Fuller Wind Turbine. This turbine is developed by Solar Aero. The specialty of Fuller Wind Turbine is it has only one rotating part, [...]

Pushker Kharecha and his colleagues believe that we should follow some practical methods to do away with coal and conventional fossil fuel emissions. We all know that use of fossil fuels leads towards carbon emissions that cause immense damage to our environment. Pushker Kharecha and colleagues voiced similar sentiments in the American Chemical Society’s [...]

Imagine a greenhouse that is producing solar power and food too. This excellent experiment is being done in Italy. The companies responsible for this project are Renewable energy company Solar ReFeel, CeRSAA and solar panel manufacturer Solyndra. The test site has been constructed at CeRSAA’s Albenga, Italy. The project intends to attain the production [...]

Now big companies are going green and proudly proclaiming it too from rooftops. Google Inc. has invested $38.8 million in two North Dakota wind farms. This is the first direct investment by Google in utility-scale renewable energy generation. These two wind farms produce 169.5 megawatts of power. These two wind farms can light up [...]

Researchers at Wake Forest University’s Center for Nanotechnology and Molecular Materials are trying to achieve source of clean and green power through pokeberries! Pokeberries could be helpful in making solar power accessible to many. Nanotech Center scientists have extracted the red dye from pokeberries to paint their efficient and low-cost fiber-based solar cells. The [...]

Fuel cells are clean and green cells. They work without polluting the environment. Fuel cells are electrochemical devices that transform the chemical energy of a fuel into electricity generating water as a by-product. Fuel cells are most used in space flights but they can be best utilized in electric vehicles to reduce air pollution. [...]

Hydrogen gas is today used primarily for manufacturing chemicals, but a bright future is predicted for it as a vehicle fuel in combination with fuel cells. In order to produce hydrogen gas in a way that is climate neutral, bacteria are added to forestry or household waste, using a method similar to biogas production. [...]

With the help of photosynthesis plants convert light energy to chemical energy. This chemical energy is stored in the bonds of sugars they use for food. Photosynthesis happens inside a chloroplast. Chloroplasts are considered as the cellular powerhouses that make sugars and impart leaves and algae a green hue. During photosynthesis water is split [...]
