The Sun Centric Centrifugal Pumps can work on solar energy and can pump 50,000 gallons, i.e. around 200 cubic meter of water per day from shallow water sources.

Shurflo Surface Pump is a strong industrial grade pump which is mainly used for applications needed for high pressure and low volume. The product is available in a wide variety of models and is mainly used for a variety of water applications.

Here's a wave power technology which you may not have heard of: It's called the Searaser and (though only in prototype stages, I've got some reservations about how well it may scale up, as well as the name which somehow I always see as 'Sea Eraser') it may be worth watching. The principle is fairly simple and proven in a different context: Use the Searaser to pump quantities of sea water up a hill where it can be stored in ponds until needed and then released downhill to drive hydroelectric turbines to create power. This is how the Searaser works:

Will Stewart has a guest post up at The Oil Drum on passive solar design techniques - Passive Solar Design Overview - Part 1. Also, at TOD, a post on the Passivhaus standard from another long-time commenter, marjorian - US Housing and the Passive Home Standard. Passive solar refers to the design and placement of a building to enable solar heating without the need for sensors, actuators, and pumps, in contrast to active solar, which utilizes pumps/blowers, sensors, and logic control units to manage collection, storage, and distribution of heat. The two techniques are not exclusive, however, and can work together effectively. As solar radiation (insolation) is a diffuse energy source, and not at the beck and call of a thermostat, passive solar design techniques are at their best when combined with other related methods, such as energy efficiency (insulation, weatherization, building envelope minimization), daylighting, passive cooling, microclimate landscaping, and a conservation lifestyle (i.e., temperature settings, raising and lowering of insulated shades, etc). Most of these topics will be covered in other articles, though passive cooling will be addressed in this series, which is intended as an overview, as a complete engineering treatment on passive solar design would require several dozens of articles.

The innovative Jug Water Filter will save you time and money - while providing great tasting purified water for pennies a gallon. Water is pulled through the filter and up the tubing by the rechargeable batter operated pump that securely sits on top of the jug. The Power Pump is USB rechargeable.

During a visit to Fort Wayne, Indiana, where he toured a manufacturer of geothermal heating pumps (GHPs), U.S. Energy Secretary Steven Chu today announced nearly $50 million from the American Reinvestment and Recovery Act to advance commercial deployment of the renewable heating and cooling systems, which use energy from below the Earth's surface to move heat either into or away from the home or building. The expanded manufacturing and installation of GHPs could aid in the creation of new jobs while reducing the use of fossil fuels. "The heat from the Earth represents a significant energy resource that can be tapped to reduce emissions contributing to climate change." said Secretary Chu. "Expanded use of GHPs in the United States will create new jobs for engineers, manufacturers and technicians while at the same broadening our nation's clean and renewable energy portfolio."

America already tried this in the 70's and 80's. It didn't work. back then almost all gas had ethanol in it and every pump was labled as such. It distroyed three of my cars and I wasn't alone. Now it is next to impossible to find gas with ethanol in it because people who know better wont buy it.

When there is an aquarium present, anyone usually want a good air mattress pump. It is almost always found powering or perhaps close to the aquarium tank because it works well this way with the garden hose smaller in length.

Concentrating solar power (CSP) is an emerging technology that offers the potential to supply utility-scale peaking power competitively. In December 2008, a 1.5 MWe solar thermal central receiver system was declared operational by plant construction company Kraftanlagen Munchen. Although solar tower technology had been built as early as the 1970s and a second commercial tower is now close to completion (see REW magazine July/August 2008) the so-called Test and Demonstration Power Plant Julich, in Germany, is the world's first solar thermal power plant erected which uses air as the medium for heat transport. In all previous plants liquid media such as molten salt or oil have been used for the obvious reason of their high specific heat capacity, which in turn results in low volume flow rates and low pumping losses.

What if it were possible to bury carbon dioxide over a mile below a power plant in the second worst air basin in the United States? In 2011 the greenhouse gas will be pumped below a power plant in the southern San Joaquin Valley of California. Located in Kern County near Bakersfield, the Clean Energy Systems power plant is powered by different kinds of natural gas and oxygen. It produces five megawatts of energy, enough for 5,000 homes, but the carbon sequestration experiment will increase that to 50 megawatts.

The solar industry is booming. With waves of investment and grants, the solar power industry is for the first time becoming a serious business. New power plants will soon be pumping power out to consumers, while other firms market to sell panels directly to the consumer, providing them with a more direct means of experiencing solar energy.

The disconnect between peak oil concerns and the presidential race is almost total. As prices at the pump rise, each candidate is now talking about their so-called solutions to the problem. Despite clear new warning signs from Russia, Saudi Arabia, Mexico, and Nigeria that peak oil is nigh, the candidates remain unwaveringly oblivious to the true causes of rising fuel prices, preferring instead to dwell on irrelevant-actually, counterproductive-measures like suspending the federal gas tax during the summer months or taxing Big Oil. This is akin to putting a band-aid on a melanoma.

ON a strip of Santa Monica Boulevard in Los Angeles, a futuristic experiment posing as an ordinary fuel station may be bringing the world one step closer to the hydrogen age. From the moment engineers started dreaming about hydrogen as an alternative to oil, they faced a nagging question: What should come first - the fuel-cell car or the hydrogen pump?

Solar energy can be utilized in various ways - to provide electricity, mechanical power, heat and lighting. Passive solar heating and cooling can save substantial electricity bills. Design of a building is very important for tapping passive solar energy. The building and windows are designed in such a way that they carefully balance their energy requirements without additional mechanical equipment. Solar benefits are utilized through windows and pumps, and fans are used minimally. Passive solar energy utilizes building constituents such as walls, floors, roofs, windows, exterior building elements and landscaping to control heat generated by sun. Solar heating designs try to trap and store thermal energy from sunlight directly. Passive cooling minimizes the effects of solar radiation through shading or generating air flows with convection ventilation.

2009 brings some new incentives for homeowners to adopt energy efficiency from both state and federal sources. The Wall Street Journal reported last week on several of these, including new provisions for tax credits in solar, small wind, and biomass stoves (those burning wood pellets or corn). In addition, this year, both solar and wind residential tax credits can be claimed against the alternative minimum tax. Improvements to weatherize your home could also qualify for an energy efficiency tax credit of up to $500. There are also new credits for upgrading your furnace, boilers, heat pumps, and water heaters. Read more at WSJ.com: http://tinyurl.com/93n535 Link to original post

The solar thermal energy or the radiant heating systems is as simple process of pumping water into solar panels to be heated and then stored in tank for ready use.

WASHINGTON - President Bush put politics ahead of the facts Tuesday as he sought to blame Congress for high energy prices, saying foreign suppliers are pumping just about all the oil they can and accusing lawmakers of blocking new refineries.

Choosing to open a green gym would require that you know environmental factors like efficient heating and cooling and what products should be included in your restrooms, as well as your business office to keep the place as green as possible.
