  • Ocean Thermal Energy and Water Production

    Introduction The scarcity of potable water is a growing problem worldwide, particularly in arid regions and among developing countries. Compounding this problem is the increasing contamination of freshwater sources, which comprise only about 2.5% of all water on Earth. Of this small portion, only 0.5% of the total fresh water available is found in easily accessible sources such as ...

  • Economics of tiny thermal power plants

    Thermal power plants is the main source of energy and electricity in India and almost all countries of the world. Most of the giant thermal power plants have capacity of 500MW to 1000 MW. Investment in such giant thermal power plants is Rs 100 million per MW including transmission lines and distribution lines. ( 60 rupees = 1 US$, MW=1000KW). So 1000MW thermal power plant costs Rs 100 million/MW ...

  • Comparison of thermal performances of flat plate and evacuated tube solar air collector at different flow rates: experimental analysis

    The thermal performances of an evacuated tube solar air collector and flat plate solar air collector are experimentally investigated at different flow rates of air. The evacuated tube solar air collector has 40 evacuated tubes and surface area, 4.44 m². This setup consists of a header of square shape. The header has a circular pipe at the centre through which the air flows. The setup contains ...

  • What Are Solar Buildings Technologies?

    Solar buildings technologies use the non-polluting power of the sun to help heat, cool, and power our buildings. Because buildings now use one-third of the energy currently consumed in this country, the potential markets for using solar buildings technologies in place of conventional ones is substantial. Whether you're a home owner, architect, builder, business owner, or industry or utility ...

  • Ocean Thermal Energy conversion and the company bringing it to market: peace for our children

    Two centuries ago, U.S. President John Adams advised us of the importance of observing our world with clear eyes, “Facts are stubborn things; and whatever may be our wishes and passions, they cannot alter the state of facts and evidence.” Though there are some facts we all would rather not face, one of those unpleasant truths is that there are places in the world where the need for ...

  • Flat absorbers with trapezoidal cavity for Fresnel reflecting solar concentrator

    The absorber is a very important component of the solar concentrating collector. The overall heat loss coefficient of the flat rectangular absorber and multi-tube absorber were studied experimentally. Both absorbers were coated with ordinary dull black paint. The heat loss coefficient was comparatively 4-11% lower in the case of round pipe absorber and increased with the absorber temperature in ...

  • Welcome to Net-Zero

    For most people (and for most homes) the likelihood of going through a whole year spending next to nothing on energy is a goal that seems far out of reach. In fact, it is only relatively recently that insulation technologies, coupled with cutting-edge renewable energy tools, have made the concept of a net-zero energy use home anything more than a pipe dream. However, thanks to a program at the ...

  • Climate change and the US energy sector

    As President Obama emphasized in his speech at Georgetown University in June 2013, climate change is happening. It is here, it is now, and as Obama warned, “Our planet is changing in ways that will have profound impacts on all of humankind.” But what are these effects? The President reels off examples: sea levels in New York harbour increasing by a foot in depth over the past century, ...

  • Ozone Brings Better Bottled Water

    The proliferation of bottled beverages worldwide and an increased awareness of consumer health issues have beverage bottlers rethinking how to keep their liquids safe for consumption.

Ozone has quickly become the disinfectant of choice among water bottlers ...

  • Industry Takes Shape: Why Digesters Make Dollar Sense Now

     THIRTY years ago, when I was a college student studying ways to convert manure to electricity, we speculated that the 1970s would be the decade of the innovators, the 1980s for the launch of operating projects, and the 1990s when the mainstream adopted the technology. Now I think our predictions for the mainstream were ten to 15 years premature — but it is happening! During the 1990s, the ...

  • Landfills Expand Energy Output

    HIGH fossil fuel prices and growing concern about global climate change are creating favorable conditions for landfill gas energy (LFGE) projects. Notably, endorsement of LFGE by Federal agencies and many states as a form of “green” power has enabled LFGE developers to earn premiums for electricity marketed through green power programs, and to benefit from expanded federal tax credits for ...
