Solar Dish Collects, Concentrates Solar Energy by Factor of 1,000

(NaturalNews) A successful test has been carried out of a new prototype solar dish that concentrates solar rays by 1,000 times, creating what inventor Doug Wood has called "the most efficient solar collector in existence."

The device is a 12-foot-wide dish made from thin, mirrored aluminum tubing and strips of mirrored glass. Water runs through the center of the dish in a coil of tubing, which is painted black for maximum heat absorption.

The collector is so effective at focusing light that when it is pointed directly at the sun, the water in the middle instantly vaporizes into steam. The prototype has also been used to set a plank of wood on fire, and researchers believe that it should be able to generate enough heat to melt steel.

Wood has signed over the rights to the device's design to a team of MIT students, who built the prototype and have launched a company to mass produce the devices. The company, RawSolar, hopes to use heat generated by the collector to produce steam for electricity generation, industrial processing, or heating or cooling buildings.

Wood spoke approvingly of the changes that the students had made to his design

"They really have simplified this and made it user-friendly, so anybody can build it," he said.

Unlike with many alternative energy sources, large-scale production is not required to make the solar dishes cost-efficient, Wood said. Because the materials to make the device are so cheap and because larger dishes require a larger, more expensive support structure, small dishes actually costs only one-third as much as large ones for every unit of collecting area.

"I've looked for years at a variety of solar approaches, and this is the cheapest I've seen," said David Pelly of MIT. "And the key thing in scaling it globally is that all of the materials are inexpensive and accessible anywhere in the world."

Renewable Energy From the Deep Ocean

Ocean thermal energy conversion (OTEC) is the method of generating electrical energy which uses difference in temperature that exists between shallow and deep waters of the oceans. Sun continuously warms oceans' surfaces which cover about 70% of the Earth's surface and in this process considerable temperature difference is creating itself, between surface and deep waters and can be used for generating enormous quantities of electrical energy with advantage that it doesn't pollute environment nor exhaust dangerous greenhouse gases. Warm surface waters and cold deep waters are the result of ocean streams which are heating the water in parts of the ocean near the equator, and cooling water in areas near North Pole and this cold water streams on ocean's bottom towards equator.

The basic principle of generating electrical energy is quite simple. Warm surface water is used for heating the liquid that has low boiling temperature (like propane gas), created steam is driving turbines of the electrical energy generators, and afterwards this steam is cooled by the cold water from ocean's deep and with which gets transformed back to liquid state. Total amount of the energy which can be gained by using this method of energy transformation is one to two orders of magnitude bigger from other methods of exploiting ocean's energy like for instance using wave power or tide power. Big problem when using this form of energy is expensive equipment and small total efficiency of the process. Because of small total temperature difference efficiency is small, it is between one and three percent. Major advantage of this process is the ecological purity of gained energy and enormous stores of this energy that can be used.

World’s Largest Photovoltaic (PV) Solar Power Plants

he Solana solar plant, 70 miles from Pheonix, near Gila Bend, Arizona, USA, will compliment the Deming plant when both begin operations in 2011. It will produce 280 megawatts of energy, provide 1,500 jobs, and cover an area of 769 hectares. The solar power facility will be the child of Abengoa Solar and Arizona Public Service Company. However, the project depends on the United States Congress to renew clean energy tax credits, which would otherwise expire at the end of 2008. (Photo: APS. Source: Newlaunches via EcoFuss.)

Now that the PV plant has received building approval, its construction is underway. Juwi Solar, the company spearheading the construction, has set a goal of completion of the plant for 2009. At that time, the facility will be able to generate 40 megawatts. (Photo, source: Juwi Solar, PDF, via PV Resources)

Solar vs. Oil

Solar power has long been a minor power source compared to mighty oil. As oil prices rise and conflicts occur in oil countries, perhaps the issue needs to be revisited.
The industrial revolution was built on the back of oil and coal. There is no denying that solar played no part whatsoever. This is particularly true since solar cells were not invented until the 1950s! That being said, it appears indisputable that we have reached or are approaching a new debate about how we deal with our insatiable thirst for power.

At first glance, the mere mention of a comparison of solar to oil as an energy source sounds laughable. It is laughable when we are talking about large scale energy production, but the tide is turning.

In a comparison of solar to oil, solar power has numerous advantages. The power source for solar, the sun, is free. Solar is available as a resource in every country, regardless of location, economic strength and so on since the sun shines everywhere. The process of converting sunlight into electricity or heating produces no greenhouse gases. If you live in a big city, you know how much pollution is in the air. You can often see it!
Flipping the coin, oil has some serious advantages over solar. We have already developed technology to efficiently convert oil to power. The cost of converting industry, vehicles and such to solar or any other power source would be huge.

For large scale energy needs, oil is still a superior choice to solar as an energy resource. The technology simply does not exist to provide solar energy solutions for vehicles, national electrical grid systems and so on. Advancements in solar technology, however, may be changing this fact in the very near future. Technologies such as quantum dots, essentially microscopic solar panels that could exist in the paint on your home, may make oil a thing of the past.

For now, oil remains the backbone upon which our energy needs sit. In the next 5, 10 or 20 years, however, new technological applications may change this. Don`t believe me? Then consider the fact oil companies such as Chevron are investing heavily in solar companies.

solar energy : home heating

So you've done everything you can to warm up your house. You have new windows, you've filled all the drafts, re-caulked where possible, but the house still never feels warm, and you're spending a fortune every month on heating. It could be you require more insulation to bulk up your energy rating.

The most non-invasive way to add insulation to a finished home is to blow it in. This is a procedure where loose fill material is pumped into the pre-existing wall with hoses through small openings made in the walls. Blown-in insulation is most commonly used in attics, in and around the ceiling joists.

You can do this yourself, but it is highly recommended that you employ an experienced contractor for the job. They have the specialized equipment for the job, know exactly where to start looking for the most effective placement of the insulation, and can often complete the work in less than a day. Some will even fill the holes and re-paint the walls.

Materials

There are various types of insulation to choose from, depending on your individual needs and preferences:

Fiberglass: Generally used in large batting form when initially insulating a home, the blown form consists of thin glass fibers. It's effective in moist areas because of its ability to dry out quickly. Larger holes may need to be drilled because it takes more pressure to blow in this material.

An eco-friendly alternative to fiberglass batt insulation is made from scraps of blue jeans combined with plastic fibers treated with borate to retard flame, mould and mildew and deter insects.

Foam: This has a higher R-value than most insulation, and is an effective repellent for insects, but it can shrink and form gaps. In some cases it can expand and cause the wall or studs to bow. It has to be installed by a licensed contractor to ensure the work is done correctly. Some of these foams are toxic and contain CFC's (chlorofluorocarbons) that are harmful to the Earth's ozone layer, or emit off-gas formaldehyde. If you decide to go with spray foam, make sure you know what you're getting. A green version exists in the form of a non-toxic, soy-based spray foam.

Cellulose: This is probably the most common type of blown-in insulation because of its eco-friendly properties. The material is made from recycled newsprint treated with fire retardant. It's non-toxic and has the same R-value as most other insulations.

Possible Issues

A qualified contractor should be aware of these risks, but you should also be informed:

- Ensure the vents in the soffits are not covered over when adding insulation to this area.

- If you discover remnants of asbestos insulation in your home it should be tested before going further. Generally, it's safe if it remains undisturbed and the toxins are not released.

Cost

Blown-in insulation is very affordable. Depending on your choice of material, the cost ranges from 60-90 cents per square foot. There may be an extra charge for drilling and painting, depending on the job. What you will gain in comfort and reduced heating and cooling bills will make it money well spent.

PHOTOVOLTAIC ENERGY

Photovoltaic energy is the conversion of sunlight into electricity. A photovoltaic cell, commonly called a solar cell or PV, is the technology used to convert solar energy directly into electrical power. A photovoltaic cell is a nonmechanical device usually made from silicon alloys.

Sunlight is composed of photons, or particles of solar energy. These photons contain various amounts of energy corresponding to the different wavelengths of the solar spectrum. When photons strike a photovoltaic cell, they may be reflected, pass right through, or be absorbed. Only the absorbed photons provide energy to generate electricity. When enough sunlight (energy) is absorbed by the material (a semiconductor), electrons are dislodged from the material's atoms. Special treatment of the material surface during manufacturing makes the front surface of the cell more receptive to free electrons, so the electrons naturally migrate to the surface.

When the electrons leave their position, holes are formed. When many electrons, each carrying a negative charge, travel toward the front surface of the cell, the resulting imbalance of charge between the cell's front and back surfaces creates a voltage potential like the negative and positive terminals of a battery. When the two surfaces are connected through an external load, electricity flows.
The photovoltaic cell is the basic building block of a photovoltaic system. Individual cells can vary in size from about 1 centimeter (1/2 inch) to about 10 centimeter (4 inches) across. However, one cell only produces 1 or 2 watts, which isn't enough power for most applications. To increase power output, cells are electrically connected into a packaged weather-tight module. Modules can be further connected to form an array. The term array refers to the entire generating plant, whether it is made up of one or several thousand modules. The number of modules connected together in an array depends on the amount of power output needed.

The performance of a photovoltaic array is dependent upon sunlight. Climate conditions (e.g., clouds, fog) have a significant effect on the amount of solar energy received by a photovoltaic array and, in turn, its performance. Most current technology photovoltaic modules are about 10 percent efficient in converting sunlight. Further research is being conducted to raise this efficiency to 20 percent.

The photovoltaic cell was discovered in 1954 by Bell Telephone researchers examining the sensitivity of a properly prepared silicon wafer to sunlight. Beginning in the late 1950s, photovoltaic cells were used to power U.S. space satellites (learn more about the history of photovaltaic cells). The success of PV in space generated commercial applications for this technology. The simplest photovoltaic systems power many of the small calculators and wrist watches used everyday. More complicated systems provide electricity to pump water, power communications equipment, and even provide electricity to our homes.

Some advantages of photovoltaic systems are:

1. Conversion from sunlight to electricity is direct, so that bulky mechanical generator systems are unnecessary.

2. PV arrays can be installed quickly and in any size required or allowed.

3. The environmental impact is minimal, requiring no water for system cooling and generating no by-products.

Photovoltaic cells, like batteries, generate direct current (DC) which is generally used for small loads (electronic equipment). When DC from photovoltaic cells is used for commercial applications or sold to electric utilities using the electric grid, it must be converted to alternating current (AC) using inverters, solid state devices that convert DC power to AC.

Historically, PV has been used at remote sites to provide electricity. In the future PV arrays may be located at sites that are also connected to the electric grid enhancing the reliability of the distribution system.

ENERGY FROM THE SUN

The sun has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the earth.

Solar energy can be converted into other forms of energy, such as heat and electricity. In the 1830s, the British astronomer John Herschel used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today, people use the sun's energy for lots of things.

Solar energy can be converted to thermal (or heat) energy and used to:

• Heat water – for use in homes, buildings, or swimming pools.

• Heat spaces – inside greenhouses, homes, and other buildings.

Solar energy can be converted to electricity in two ways:

• Photovoltaic (PV devices) or “solar cells” – change sunlight directly into electricity. PV systems are often used in remote locations that are not connected to the electric grid. They are also used to power watches, calculators, and lighted road signs.

• Solar Power Plants - indirectly generate electricity when the heat from solar thermal collectors is used to heat a fluid which produces steam that is used to power generator. Out of the 15 known solar electric generating units operating in the United States at the end of 2006, 10 of these are in California, and 5 in Arizona. No statistics are being collected on solar plants that produce less than 1 megawatt of electricity, so there may be smaller solar plants in a number of other states.

The major disadvantages of solar energy are:

• The amount of sunlight that arrives at the earth's surface is not constant. It depends on location, time of day, time of year, and weather conditions.

• Because the sun doesn't deliver that much energy to any one place at any one time, a large surface area is required to collect the energy at a useful rate.

SOLAR THERMAL HEAT

Solar thermal(heat) energy is often used for heating swimming pools, heating water used in homes, and space heating of buildings. Solar space heating systems can be classified as passive or active.

Passive space heating is what happens to your car on a hot summer day. In buildings, the air is circulated past a solar heat surface(s) and through the building by convection (i.e. less dense warm air tends to rise while more dense cooler air moves downward) . No mechanical equipment is needed for passive solar heating.

Active heating systems require a collector to absorb and collect solar radiation. Fans or pumps are used to circulate the heated air or heat absorbing fluid. Active systems often include some type of energy storage system.

Solar collectors can be either nonconcentrating or concentrating.

1) Nonconcentrating collectors – have a collector area (i.e. the area that intercepts the solar radiation) that is the same as the absorber area (i.e., the area absorbing the radiation). Flat-plate collectors are the most common and are used when temperatures below about 200o degrees F are sufficient, such as for space heating.

2) Concentrating collectors – where the area intercepting the solar radiation is greater, sometimes hundreds of times greater, than the absorber area.

Here Comes the Sun: Solar energy is becoming more attractive every day

The price of a barrel of oil has never been higher ($62.00+ in summer 2005 even before the chaos caused by Katrina). Some say this is a temporary spike, but more and more analysts are agreeing that this kind of pricing is here to stay. World consumption is at an all time high and given the new thirst for oil in China and India it is unlikely to diminish. According to International Energy Outlook, global demand is expected to continue to increase by as much as 59% in the next fifteen years.

Already, consumer energy bills have been increasing on average 6.5% per year for the last thirty years in the United States. Given the dramatic rise in the cost of producing energy using traditional non-renewable resources, this rate is bound to be overtaken by unheard of price increases in the very near future. And for consumers who are becoming more and more environmentally conscious, the thought of the millions and millions of tons of CO2 and other bi products being released into the atmosphere annually through the use of fossil fuels in creating energy is very alarming.

It is a no brainer that our reliance on oil to create energy leaves us very vulnerable. There are renewable technologies that produce energy, but the problem has been one of cost effectiveness. It has always been cheaper to supply energy using fossil fuels, and consequently, renewable sources such as solar or wind power have not taken off. But the situation now appears to be changing. More and more, our consumption of energy is outstripping supply. The grid can barely keep up with demand and rolling blackouts are no longer just a concept. No wonder governments are looking for alternatives. And no wonder everyone is talking solar once again.

In 1985 annual worldwide solar power system installation accounted for 21 megawatts of power. By 2004, this had multiplied to an incredible 927 megawatts in new installation power production alone. The demand for solar produced energy over the last several years has increased annually about 25%, although in 2004 sales were up a whopping 67% from the previous year.

There are several reasons for this increase in popularity for all things solar powered. Beyond the obvious environmental considerations and the privilege of not having to rely on power from a grid that is aging and stretched to capacity, solar is getting cost effective. While traditional energy production gets more expensive, technological advances are making solar power cheaper.

In 1980 the cost of harvesting energy from the sun stood at about $100 per watt. Literally a hundred times more expensive than the going rate of electricity, these systems were not economically viable. By 1999 however, technology had reduced this to about $4 per watt and costs have continued to decline by about 5% per year since. The Return on Investment is becoming very attractive for many commercial organizations and consumers.

Efficiencies have been realized in several technologies. The inverters that transform the collected DC energy into usable AC energy used to deliver only about 65% efficiency. 35% of the collected energy was lost in the transformation process. Today’s transformers are so efficient they deliver up to 96% of collected energy into usable AC current.

Photovoltaic technology has also made solar collection far more efficient. Twenty years ago, only 5% of the sun’s energy hitting a solar charging panel was harvested. This figure is now in excess of 15% and will continue to climb as more efficient compounds are designed and introduced in the manufacture of these photovoltaic panels.

All levels of government are increasingly looking at solar to provide stable, cost effective and environmentally friendly power. 35 states now have some kind of rebate program for homeowners that install solar power systems. And this is not just the southern “sunny states”. While California is the clear leader in promoting solar powered energy solutions (a program introduced in 2003 is promoting the introduction of solar powered energy systems into a million homes over the next several years) New Jersey and New York are next in line for solar investment.

At the municipal level, many jurisdictions have introduced solar solutions for traffic and streetlights. 50% of the energy used to run the City of Sacremento’s water purification plant is solar. NASA uses solar powered energy systems in many of its buildings. And governments are not using solar just because it is good for the environment and sets an example for commercial entities and consumers (although these benefits cannot be lost on them!). They’ve concluded that opting for solar systems will save them hundreds of thousands of dollars.

With so many rebate programs today homeowners are coming to the same conclusions. Once the initial return on investment is recouped (as early as 4 to 6 years with the rebate programs in California for example), solar users don’t have any additional energy bills, almost no maintenance to worry about and are not slave to an electrical grid that is becoming more and more fragile as demand outstrips supply. No wonder solar power is getting attention!

Solar power is still more expensive than traditional energy production methods, but the gap is narrowing every year. Solar power applications are also multiplying at an amazing rate. House heating, solar pool lighting and heating, hot water tank heating, calculators, flashlights, solar garden lighting and on and on. Solar is clean, it’s efficient and it’s here to stay.

Solar energy >>> hot water

Residential hot water is a significant energy consumer for most households. In fact, hot water is sometimes the largest single energy cost. Using solar energy to provide at least some of the hot water in your household can result in significant savings.

There are several ways that solar energy can be integrated into a hot water system. Although solar boilers can be used on their own, they are most often used in conjunction with traditional water heaters which are powered by gas or electricity. In this kind of system, the water heated with solar energy can be used on its own (if it is hot enough) or as preheated water for the traditional water heater. Pre heated water will also dramatically decrease your energy bill.

Solar boilers can be used in any type of climate but are most practical in areas which don't have freezing weather during the wintertime. Solar hot water systems in colder climates can use indirect heating systems which do not expose the water to the freezing temperatures. Instead, a fluid that resists freezing circulates through the solar panels and is used to heat the water. Southern climates can use direct heating systems where the water itself passes through the solar panels installed on the roof.

There are two basic types of solar hot water systems -- active and passive. Passive systems rely on gravity and the natural flow of water from hot to cold. They are simple systems and require very little maintenance. They are durable and long-lasting. You can easely build simple systems yourself all you will need are parts that you can find in any hardware store.

Active systems make use of pumps to circulate the water. In some systems, the pumps can be powered with solar energy; otherwise they must be connected to the household electrical supply. In both systems a storage tank is needed to hold the heated water.

On hot days with plenty of direct sunlight solar systems can heat water with surprising efficiency. During this kind of weather, there may be no need to use electricity or gas as a backup. When the weather is colder, the solar heaters can preheat the water which passes into the traditional water heater. This preheated water requires much less energy to bring to proper temperatures which can result in significant savings on your energy bills.

As with all alternative energy systems there is a lot of room for your own imagination if you like that. If you don't you don't and just use the technology, but for those who like to play around with technology like myself these systems offer a myriad of possibilities to think about.

For example, a stirling engine converts changes in temperature into mechanical motion, for example to generate electricity. Mmm, that's a nice thought. A change in temperature is something this system will provide, but it will also heat your water. A double benefit?

solar energy of the future, perpose

Light (particularly sunlight) can be used to create heat or generate electrical power. This is referred to as solar energy.

It is a clean form of energy production, which doesn't pollute the environment as some other forms of energy production do.

There are two forms of solar energy. The first is solar thermal conversion, which uses sunlight to create heat and then electrical power. The second is photovoltaic conversion, which uses sheets of special materials to create electricity from the sun. "Photo-" means "light," and "voltaic" means "producing electricity."

Solar Energy and the Future

An advantage to solar power is that it can reduce expenses. It can also be portable. When one is backpacking in the wilderness or traveling far from power grids, solar power can provide a means of powering electronic equipment.

Another advantage is, of course, the lack of pollution created by solar energy production. In fact, if all of our electrical energy were produced by such means, we might not be worrying about global warming and the other destructive effects of pollution on our environment.

These threats to our environment also pose a threat to mankind. Solar power could be developed to a point where it, along with other forms of renewable energy, would replace harmful means of electricity production.

It isn't necessarily impossible to have a clean and safe Earth. We just have to work on it.

Photovoltaic Conversion

As covered above, photo means "light." It comes from the Greek word “phos,” which means "light."

“Voltaic” means, "producing electric current." The word comes from the name of Alessandro Volta, an Italian physicist who was a pioneer in the field of electricity during the 1700's. (His name is also where the word "volt" comes from.)

Photovoltaic means, "creating electrical energy when exposed to light."

A “cell” is a device that produces electricity. An example of an electrical cell is a flashlight battery.

Photovoltaic cells produce electricity when they are exposed to light. They usually consist of panels. The panels contain two layers of different materials.

When light hits these two layers, one of the layers becomes positively charged, and the other becomes negatively charged.

This works similarly to a regular flashlight battery, which has a positive end and a negative end. When a wire connects the two ends, they produce an electric current.

When the two layers of material in a solar cell are exposed to light, they create an electric current.

The AMOUNT of electricity generated by a solar power cell depends on several factors. Mainly:

-How big is the solar power device, and how much surface is exposed to the sun?
-How strong is the sun? (This depends on time of day, weather, latitude, etc.)
-How long is the solar power device exposed?
-How much impediment is there to the light? (Clouds, mist, dust, dirt, etc.)

In other words, a solar power cell generates electricity faster when the sun (or light) is brighter. A device with larger solar panels will produce more electricity than one with smaller panels. Exposing the cell for a longer period of time will create more electricity than exposing it for a shorter period of time. A panel near the equator will be more effective than one in an arctic region. A solar panel in misty or dusty conditions does not create as much electricity as it would in full, unobstructed sun.

Some solar cells produce only enough current to power small electronic devices, but can be "daisy-chained" (connected together) in order to create more electricity for other items.

Solar cells which produce enough electricity to run larger equipment (such as laptops) may be larger, more expensive, or heavier than the others.

But there are many varieties available. Individuals and companies are consistently striving to create lighter and more efficient portable solar cells.

Solar energy - Solar Thermal Conversion

Solar Thermal Conversion

Solar thermal conversion systems use reflectors or mirrors to concentrate sunlight to extremely intense levels of heat. (Solar means "of the sun," thermal means "of heat" and conversion means "changing something from one form to another.")

You can understand this better if you consider the example of using a magnifying glass to start a fire. You may have heard of this or even tried it before. You can hold a magnifying glass under the sun, and concentrate the light on a small pile of flammable materials. The magnifying glass will make the sun's heat much stronger, and will light the materials on fire. It has been said that a magnifying glass one meter in diameter, held under the sun, will create a ray hot enough to melt stone.

If you want to experiment, hold a magnifying glass flat under the sun and put your hand under it. Very soon you will need to move your hand away - don't burn yourself.

Solar thermal conversion systems use mirrors or reflectors to concentrate sunlight onto containers full of liquid. Sometimes water is used. Sometimes other liquids are used, which retain heat better than water.

The liquids are heated up to high temperatures, and this produces steam. The steam is used to turn a turbine. The turning motion of the turbine is used to create electricity.

How does a rotating motion create electricity? When you set up a coiled wire or similar device to rotate between two magnets, it generates an electric current. This is how electric generators work, as well as windmills, nuclear power plants, and other energy plants which use such things as coal, gas, or petroleum.

Windmills use the wind to create the turning motion. Nuclear power or fossil fuels are used to heat water up, thus creating steam to turn the turbines.

Solar heating is another form of solar thermal conversion. In solar heating, an absorber is used to take in sunlight and convert it to heat. The absorber could be something simple, like black paint, or it could be a special ceramic material. A heat absorber is considered to a be good one when it collects at least 95 percent of the sun's radiation.

The absorbers are then used to heat a fluid, which is then circulated to warm up buildings or to create hot-water supplies.

Solar,solar and only solar energy

That is all we need. Solar energy is clean, and expandible.
Solar energy is the future. All citizens of US and Europe suport solar energy.

Solar technologies

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels,solar thermal collectors, with electrical or mechanical equipment, to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used.

Forms

Solar energy comes in many forms. The majority of us are most familiar with solar cells, but there are actually many different ways to create and store solar energy. Here are a few of those ways:

· Solar Cells – Most of us have seen solar cells used on calculators with LCDs. But they have also been used in many other ways. Solar cells use semiconductors (oftentimes, silicon) to generate electricity, directly from the sunlight.

· Solar Fibers – This is also a photovoltaic device (like the solar cells), only it does not use silicon. Rather, it has a solar tape that is made with titanium dioxide. This tape could actually be combined with building materials or even clothing.

· Solar Pond – A solar pond is made of three layers: the top layer as low salt content. The middle layer is an insulating layer with salt, and it prevents natural convection in the water (which would normally cause heat exchange). The bottom layer as a very high salt content, and this layer can approach high temperatures. Because of all the densities in salt of the different layers, there are no convection currents (which normally transfer heat to the surface and then the air). The heat that gets trapped in the bottom layer can be used to heat buildings, generate electricity, or in industrial processes.

· Solar Chemical – There are a number of different solar energy processes that absorb sunlight in a chemical reaction to create that solar energy. More research is needed on solar chemical energy before we can apply it practically. Much of this research is on photoelectrolysis of water.

· Solar Updraft Tower – This is a type of solar energy plant in which air passes under an agricultural glass house, gets heated by the sun, and is then channel up toward a convection tower. It is used to drive turbines which generate electricity.

· Energy Tower – This tower uses water, unfortunately, but it is also a good design and works in a similar way to the solar updraft tower. Water is sprayed at the top of the water. The water evaporates which causes a downdraft by cooling the air. This coolness increases the density of the air and then drives turbines that are at the bottom of the tower.

These are just a few ways in which solar energy has been and is being created. Perhaps the most common household type of solar energy is that created by solar cells. Nonetheless, these other types are very promising and certainly have their place.

Solar energy

In today's universe of amending applied science, we require to realize the informant of energy that the sun is and discover how to utilize that energy more expeditiously. Did you recognize that you are able to more modest your monthly utility charges by reducing the amount of regular electrical energy that you use at house? When you set up a Solar Energy Kit at home you will be cutting down the quantity of fossil fuels that are being applied which successively serves to protect the surroundings.

Whenever you would like to change your home to solar power, there are a few matters that you had better consider. How much energy do you apply in you house? What types of gadgets would you require to power? Do you have an effective localization to set the solar power panels?

Buying a beneficial, authentic solar energy kit is the initiative significant step to converting your home to solar energy. If you purchase a kit that derives collectively the installation will be practically easier, then you will not have to headache about attempting to figure everything out and purchase the individual parts that are necessitated.

If you have not determined where to locate the panels, you should think positioning them on the roof because it is a eminent place that is still circumspect. The roof is nearer to the sun so it passes an idealistic place for them-- the panels will require to be directly in the suns rays so that they may accumulate energy from the sun, and then carry-over that energy to a converter to storage the energy until it is wanted. It is really authoritative to make a point that the solar energy panels are aimed in a position where they will be in direct impinging with the sun as much as possible. Consider the environment around your house to avoid directing the panels in a place that is got across by other buildings or over-hanging branches.

The advantage of changing your house to solar power is to assist to protect the surroundings. Fossil fuels that are utilized specified coal and oil contaminate the air and damage the environment, but the solar energy kits have no damaging effects on the surroundings.

If you determine that you would like to serve to protect the environment by converting you house into solar power, be sure that you purchase a effective solar energy kit that admits entirely of the essential parts. It is very lenient procedure and you will be exhilarated with the effects.
