Models Of Solar Power Water Pumps
While oil is considered as the most precious commodity in most of the world, many places value water far more than oil. Shortage and contamination of water is a serious problem there. Water required for drinking, industry, and irrigation is badly needed in such parts, especially in the developing countries of Asia and Africa. There is sufficient underground and surface water present in these areas to meet the population’s requirement. What is lacking is the efficient means of pumping this water out for people’s use. Solar power water pumps are one efficient means to achieve this goal in the future.
Ideal Solar Power Water Pumps
Ideally, the solar power water pump is a low-cost, high-efficiency device, which converts the sun’s heat directly into mechanical power for driving the pump. Such a pump is able to use an array of tubular collector elements for heating air. The pump combines an evacuated tubular solar collector array with a diaphragm type pump. It is equipped with an internal heat exchanger, which uses heat from the heated air to generate steam from water. The steam drives the diaphragm pump. The heat exchange medium might be something other than water, for example freon or ammonia.
Models Of Solar Power Water Pumps
A number of different models have come out for the solar power water pumps. Two useful models came from Stephen Salter and Joanne Posthumus in April 2003. Both models are built on the nature’s principle of drawing water used by the plants.
The First Model: The first model from Salter and Posthumus consists of a well shaft that extends down in the ground to a significant length (as does a tree trunk). The shaft might extend down to the groundwater or to some depth below the ground surface, or to lift the reservoir of pure water above the ground. This results in gravity feed, a cost effective method of pumping water.
The Second Model: The second model uses a flat absorbent fiber, which is placed behind a black plastic sheet. Fiberglass is used as wick in this model. Since the black plastic sheet absorbs the solar energy, the reflectivity of the wick is not important. Both the fiberglass wick and black plastic sheet are enclosed in clear plastic, which is stapled to the wooden frame. A trough collects the condensing water droplets. There is a collecting jar for fresh water in the ground at the lower left-hand corner of the frame.
Prospects of the Models
With models of solar power water pumps by Salter and Posthumus, it is expected to get pure water from marshy or even contaminated soils. These pumps will also prove effective in water-logged areas or where saline water exists underground.

Your Questions About Solar Generators Reviews
Jenny asks…
Are there problems adding other charging units like wind power to a Harbor Freight Solar Panel ChargeControler?
I would like to buy a small wind generator and just add the negative and positive wires to the negative and positive wires in my Harbor Freight Solar Panel kit. The Harbor Freight Solar Panel kit’s charge control will still protect the battery from over charging right? Even though the charge controller would be buffering more wattage then what the manufaturer probably intended it to buffer? If so, could there be long term implications on the charge controller or battery?
admin answers:
Hey Me, what are you using for battery storage? If I understand the harbor freight kit properly, it does not have a battery included, or it is a very small sealed AGM type battery. If that is the case, don’t bother adding another source of charging power, you’ll just fill that battery up faster and still have no place to put your excess energy. If you have a good sized deep cycle battery or two hooked up, my suggestion is simply get a wind turbine that has it’s own charge controller, most of them do. Then wire it straight to the battery bypassing the harbor freight unit. A good example would be Southwest Windpowers Air 403, puts out up to 300 watts, although in ideal conditions on a tall tower, but has its own internal regulator, like a car alternator. So the two wires coming down the tower go straight to the battery, and the turbine is already prevented from overcharging anything.
In most wind/solar power systems, the charge controller is the achilles heel. It is the one thing that breaks down first and causes the most problems. We’ve been living in a wind and solar powered home for years now, I can speak from experience on this. We’ve not purchased the HF kit because the panels are not built as robustly as they need to be to be mounted on the roof of a home in all weather conditions, and the wiring harnesses are not designed for permanent installation, to be sunlight resistant, etc. Also the electronics are not UL listed to my knowledge, so they would not be legal for in home installation either. They are terrific little units to make small amounts of power in a portable application, like camping, or a remote shed for example. Adding another source of power to be fed through the existing controls of that kit would be like welding a bed on the back of a Ford Pinto in order to use it as a pickup truck. My suggestion is to have a good sized battery pack, like a pair of Trojan T-105 golf cart batteries (220 amp hours) then get a small turbine with its own regulator, and wire it straight to the batteries. The batteries will happily take a charge from either source, or both simultaneously, that’s how our home works. If you really want to do some shopping for this stuff, get a subscription to Home Power Magazine, they regularly run articles on all the available panels, turbines, controllers and othe components to home power systems. If you subscribe, you can use their website to review archived articles in past issues that have all the write ups you’re looking for. Good luck Me, and take care, Rudydoo

What are some of the best rechargeable flashlights (solar/winding/shaking/plug-in/etc)?
I think I would like a solar or electrical outlet plug-in rechargeable flashlight for home use, especially for power outages, and a winding/shaking one to keep in the glove box of my vehicle.
What are some of the best performers out there? The only one I’ve found with consistently good reviews is the SolarLite (Costco, Amazon).
admin answers:
Hey jdude
for rechargable go to
http://www.maglite.com/
have been using this brand for years at work.
I have tried a couple wind up lights in my vehicle and they dont last. I think the temp and humidity swings have an effect on generator and/or battery. I now have an LED 2 cell for the car now. It holds up fine.
I’ve had good luck with this wind up from radio shack. Keep it in the house near crawl space for emergency reasons. Tornado/asteroid strike or nuke fall out. (gosh i hope none of this ever happens)

Michael asks…
What is the establishment cost for a coal burning factory?
I need this for a science assignment. Holy crap do I hate science.
So yeah, what is the establishment cost to set up a coal burning factory? (Where the coal is transferred into energy)
admin answers:
The current establishment cost of a coal fired power station is about $2000 per kilowatt of power produced. Over a 50 year life; this is quite low compared with establishment costs for wind and solar power generation, and a lot (hundreds) of wind generators are needed to produce the same power output of a large coal powered generator. This is why it is proving difficult to replace coal for large scale power generation.

Year 12 Physics – How do generators and transformers work?
I have a basic idea but am having a little trouble understanding it completely – so i can answer abstract questions in texts… and the textbook is just confusing.
Anyone want to explain a little?
admin answers:
A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled electrical conductors. A changing current in the first circuit (the primary) creates a changing magnetic field; in turn, this magnetic field induces a changing voltage in the second circuit (the secondary). By adding a load to the secondary circuit, one can make current flow in the transformer, thus transferring energy from one circuit to the other.
The voltage in the secondary circuit is in general different from the voltage in the primary circuit.
In electricity generation, an electrical generator is a device that converts mechanical energy to electrical energy, generally using electromagnetic induction. The reverse conversion of electrical energy into mechanical energy is done by a motor, and motors and generators have many similarities. The source of mechanical energy may be a reciprocating or turbine steam engine, water falling through a turbine or waterwheel, an internal combustion engine, a wind turbine, a hand crank, the sun or solar energy, compressed air or any other source of mechanical energy.

The Advantages Of A Solar Power Water Heater
Solar power energy is an exceptionally clean and abundant form of energy resource that can be used in the supplementing of many energy needs. Solar energy can also be used as a form of heat, such as in the form of water heating, where a solar power water heater is thus used. For the most part, a solar power water heater uses a small solar electric module in order to power the pump that is needed to circulate the heat transfer fluid through the collectors.
What Is A Solar Power Water Heater?
Basically, a solar water heater consists of three components, which are: a solar collector, which converts solar radiation into useable heat a heat exchanger or pump module, which transfers the heat from the solar collector into the potable water and a storage tank that is used to store the heated water.
What Are The Advantages Of A Solar Power Water Heater?
There are many benefits that you can receive from having a solar power water heater in your home, such as the fact that because a solar power water heater greatly reduces the amount of fuel that you need to heat water, you are then having to use a greatly lessened amount of fuel for your home, saving an immense amount of wear and tear on the environment as well as saving the earth’s available fossil-fuels, which are quickly becoming quite sparse.
As well, for the most part solar water heaters use a small solar electric module in order to power the pump that helps to circulate the heat transfer fluid through the collectors, and this will allow the solar water heater to be able to continue to operate even in the event of a black or power outage. There are a couple of basic different categories of solar water heaters, the two most primary of which are: year-round and seasonal.
The year-round solar water heaters are ones which are specifically designed to operate reliably throughout the entire year, and are generally more expensive than that of the seasonal systems, however they do provide more energy savings for the most part, and the benefit of having them assured to work steadily throughout the year is an incredibly important advantage.
The seasonal solar water heaters are then designed to operate only when the outdoor temperatures are above freezing. Therefore, although they are less expensive than the year-round solar water heaters, they have the disadvantage of only being able to work during the colder months of the year. As well, when compared to the year-round type of solar water heaters, these heaters do not produce as much heat annually because they operate for a much shorter duration of time.

Your Questions About Solar Energy Pros And Cons
Betty asks…
Pros and Cons of using nuclear energy to produce electricity?
Please give me some pros and cons of using nuclear energy for producing electricity! List as many as you know.
admin answers:
Pros:
Cheaper per kW-hr than gas, coal, petroleum, and solar energy production.
Zero carbon emissions power production
Higher output than any other energy source for a given area
High paying jobs stimulate local economy more than other forms of energy production
More jobs created than from gas, coal or petroleum production
With reprocessing, nuclear energy could provide a nearly endless supply of power at current demands.
Cons:
Re-Processing of commercial fuels currently creates issues with waste volume in the United States, leading to storage and disposal issues.
Wastes are highly radioactive and must be handles carefully and dealt with using engineered safety features.
Public opinion of nuclear power presents a “not in my back yard” mentality, even with US plant design being some of the safest plants in the world to operate.
Plants must be built in geologically stable area, or engineered to withstand geological events to prevent the release of contamination.
The approval and construction process for new nuclear plants is quite costly, making it difficult to build new facilities.
Lizzie asks…
What are Problems of Fossil Fuels and the Advantages of Solar Energy.?
What are the pros and cons of Solar Energy with respect to cost, impact on the environment, availability etc.
admin answers:
There are several problems with fossil fuels. They are a limited commodity, they cause pollution when burned, and they are destructive to drill for or mine.
Solar energy is a growing technology right now. People who have solar panels on their houses often generate more electricity than they can even use, and in some places they can sell it back to the power companies and make a profit while not paying for electricity.
At present, solar panels are expensive to buy, but this will change as more people buy them, just like any other technology.
For the environment, I would guess that solar energy is almost completely harmless. I don’t know what kind of chemicals that are required for making solar panels, but once they are produced, solar energy uses a virtually unlimited energy source that is clean to harvest and gives off no emissions.
