Alternative Energy

Tiny generators developed at the University of Michigan could produce enough electricity from random, ambient vibrations to power a wristwatch, pacemaker or wireless sensor. The energy-harvesting devices, created at U-M’s Engineering Research Center for Wireless Integrated Microsystems, are highly efficient at providing renewable electrical power from arbitrary, non-periodic vibrations. This type of vibration is [...]

Scientists are quite optimistic that hydrogen will emerge as the fuel of the future and the world would be driven by ‘hydrogen economy’. The only byproduct of hydrogen fuel is water vapor. By using hydrogen fuel we can reduce the harmful effects of greenhouse gases. Currently many research labs are engaged in duplicating the [...]

Since time immemorial human beings are trying to use solar energy for their survival and day to day use. We know that green plants create their own food and energy with the help of photosynthesis. Photosynthesis happens in the presence of sunlight, water and carbon dioxide. The end results are food, chemical energy and [...]

Now we can have a green charger for our computers and laptops. We can take our laptops to outdoors and keep on using them without bothering that the charge will run out. Muzatch offers a solar charger for our computers. It is known as the MZH-SP-6500 / SP-6000 renewable energy charger. If one is [...]

SunEdison is a division of MEMC Electronic Materials, Inc. They have bagged a project to develop and construct a photovoltaic solar power plant in Northeastern Italy, near the town of Rovigo. This solar power plant will have a capacity of 72 Megawatt (MW). This will be the largest solar power plant in Europe. SunEdison [...]

With each passing day, scientists are coming out with unique solutions to lessen our dependence on fossil fuels. They are now thinking of turning stray forms of energy such as noise or random vibrations from the environment into useful form of energy. They want to use piezoelectric effect for such purposes. Some materials produce [...]

If we go by the stats, every year 11 billion pounds of poultry industry waste accumulates annually, because we have gigantic appetite for poultry products. They can’t be stuffed into pillows. Mostly they are utilized as low-grade animal feed. Scientists in Nevada have created a new and environmentally friendly process for developing biodiesel fuel [...]

Alternative energy can be a boon for third world countries. Normally governments have to invest vast sums of money in developing infrastructures for a long period of time in underdeveloped areas. If we consider the example of cell phones, they have bypassed the usual wires, poles, roads, telephone exchange infrastructures. People residing in remote [...]

The researchers of Massachusetts Institute of Technology (MIT) have uncovered a new phenomenon of carbon nanotubes. They found that carbon nanotubes discharge powerful waves of electricity under certain circumstances. MIT team named it as thermopower waves. They are pinning their hope on thermopower waves to produce electricity to be utilized in small electrical [...]

We all are familiar with the effects of carbon dioxide on our environment. Carbon dioxide is responsible for causing the greenhouse effect. If scientists can breakdown this gas into other form it would lead us to reduce the concentration of this gas into environment substantially. It would mean dealing with the root cause of [...]

Wave energy is among the impressive list of renewable energy resources that is being developed in the United States. New Jersey-based developer, Ocean Power Technologies has launched a project that features the nation’s first commercial wave power farm off the coast of Reedsport, Oregon. Once the project is completed, wave energy will generate power [...]

Nanoscience is quite fascinated with the process of photosynthesis. They want to duplicate this process exhibited by green plants and utilize the solar power for energy use. Till now power generating solar panels are not in a position to replace the fossil fuels. They produce little amount of energy and quite expensive also. Generation [...]

Sunpods Inc. is California-based manufacturing company. They produce modular, fully integrated and tested solar power generation systems. Recently they have come out with an idea of the first solar power-assist system for buses. They should be applauded for developing it in a mere six weeks. Their partner is Bauer Intelligent Transportation. The system developed [...]

Google’s Bill Weihl expresses his opinion, “We see a chance to make a difference in the field of renewable energy and energy information that can help bring the world to a lower carbon and more efficient economy.” Google is known for its Internet search engine. Now they want to make inroads into green technology [...]

It should come as no great surprise that walking with a prosthetic limb is difficult. According to a newly published paper on prosthesis, walking with a prosthetic foot requires 23 percent more energy than walking naturally. This is because a natural gait returns and recycles energy in an efficient way, but a prosthetic limb [...]

PlanetSolar enjoys the distinction of being the largest solar-powered boat in the world, and it’s ready to take on the world. This beauty’s vital stats are: weight: 60-ton, a 470-square-meter are covered by 38,000 solar cells to generate 103.4 kW of energy. 18 million euro ($24.4 million) was spent to adorn this beauty in [...]

Yi Cui, an engineer at Stanford University, leads a team that may take nanotechnology to the next level by creating paper batteries and fabrics that can conduct energy. At a recent demonstration, Cui took pieces of fabric and regular paper and soaked them in an ink that contains nanoparticles. The infusion of these particles [...]

As fossil fuels continue to diminish and climate change poses an ever-increasing threat, scientists around the world are searching for new and more efficient methods of generating energy. Wind energy is one of the more promising alternative energy sources and Norwegian scientists are currently in the development stages of what promises to be [...]

Science continues to amaze and one of the latest discoveries may literally change the world as we know it. This tiny solar-powered sensor can fit on the face of a penny and barely cover up the date. How this little wonder, developed at the University of Michigan, is able to create the power of [...]
