  • Caltech working to solve the world`s energy problems with the help of inVia

    Fossil fuels are the world's main fuel source for transportation, heating and generating electricity. As a by-product, high levels of CO2 are released into the atmosphere. With the drive for sustainable energy production, a method that generates easily-stored fuel from sunlight—and absorbs CO2—is a very attractive proposition. The California Institute of Technology ...

  • 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 ...

  • Solar hot water system

    Solar hot water systems (e.g. residential) do not produce steam, for example. Thus, solar hot water systems cannot push a steam turbine and will not generate electrical power. Solar hot water systems are used for heating and hot water requirements, not electrical power. If this is offsetting electrical hot water or electrical heat, then these are more like 'negawatts' than Terawatts. Steam ...

  • Solar Detoxification

    Introduction: In this process, vacuum extraction is used to remove contaminants from soils. After condensation, contaminants are mixed with a semiconductor catalyst such (e.g., titanium dioxide), and fed through a reactor which is illuminated by sunlight. Ultraviolet light activates the catalyst, which results in the formation of reactive chemicals known as 'radicals'. These radicals are ...

  • Solar drying of sewage sludge - An old method with modern technology using Wendewolf®

    Any Sewage Water Work throughout the world will produce sludge, a form of biomass growing in the basins. This biomass has to be evacuated and is, generally speaking difficult to handle! When liquid it has a dry matter of 3 to 4 %, or only 30 to 40 kg per ton of sludge, when mechanically dehydrated to 20 - 25 % most of it is still water, as an average  750 to 800 kg per ton of filter cake. ...

  • On rooftops worldwide, a solar water heating revolution

    The harnessing of solar energy is expanding on every front as concerns about climate change and energy security escalate, as government incentives for harnessing solar energy expand, and as these costs decline while those of fossil fuels rise. One solar technology that is really beginning to take off is the use of solar thermal collectors to convert sunlight into heat that can be used to warm ...

  • The Burning Facts About Solar

    Did you know that solar Energy comes in different forms?  As we all know, the development of solar energy is important because of its great contribution to our electricity sources. We might even think that it is just a simple development that deals about replacing and becoming one of the alternatives for our electricity sources that we can find. When talking about the development of solar ...

  • Water vapour permeation measurement for PV Solar Cell packaging

    With fears of carbon dioxide causing global warming and diminishing supplies of fossil fuels, a looming energy crisis is affecting all countries.  As a consequence, a great deal of world-wide effort is going into the development of alternative energy technologies.  At present, wind, hydro and geothermal are becoming well established with more niche roles for tidal and solar. The latter ...

  • A brighter future for solar in Texas

    I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that. - Thomas Edison, in conversation with Henry Ford and Harvey Firestone, 1931 According to the State Energy Conservation Office (SECO), Texas has the greatest solar energy potential of any state in the country. “If photovoltaic (PV) systems operating ...

  • In the World: Small Mexican village produces clean water with solar-powered system

    MIT-developed system runs autonomously, producing 1,000 liters per day.
