Using Solar Power to Heat Your Pool
Compared to gas and heat pump pool heaters, installing a solar pool heater is now the most practical way keeping your pool water at the right temperature year round. Given that your pool enjoys 4 to 5 sun hours per day, a solar pool heating system is very much feasible. Depending on your home's location, a good solar power-operated pool heating system allows you to extend swimming seasons for up to twelve months. While it costs a substantial amount of money to get installed, it has absolutely has operating cost. It does no use fuel which means no pollution. Another great thing about a solar pool heater us that it can last up to 20 years, comes with a 10-year manufacturer's warranty, with minimal maintenance required.
While there is solar heater equipment that you can buy for a couple hundred bucks, the overall cost of installing a complete solar pool heater system for an average size of pool can cost up to $3,000. Despite the high cost of installation, it saves much on its operating and maintenance costs. To understand the savings that this type of water heater yields, you must first understand how the system works.
All solar pool heater system works with a solar collector, filter, pump and flow control valve. It operates under simple mechanisms. First, the water is pumped from the pool to the solar collectors where the water is warmed by the sun. The warm water is then pumped back into the pool for your enjoyment. The solar collector refers to the device through which the pool water is delivered and heated using solar energy, the filter traps the debris carried by the water through the pumps, the pump provides the force that drives the water into the from the pool, into the collector, and back to the pool. The flow control valve is an automatic or manual device that regulates and diverts the flow of pool water to the solar collector.
A solar pool heater works with two types of solar collectors; the unglazed and glazed pool heating collector. An unglazed solar pool heating collector is less expensive than the glazed collectors since it does not use glass covering. Instead, it used heavy-duty rubber and plastic protectors that are treated for ultraviolet (UV) protection. It works great on indoor pools during the cold climates. On the other hand, the glazed solar pool water heating collector are made with copper tubing on aluminum plates with iron-tempered glass covering, which somewhat increases its cost. During cold weather applications, it captures solar heat more effectively than the unglazed collector. Therefore, it is more effectively when it comes to year-round pool heating operations and can work under any climate conditions. Usually, the service life of these collectors would depend on the climate and how tedious it is used in solar heating applications. Both the unglazed and unglazed collectors have freeze protection which is useful during extremely cold.
Although solar pool heating systems are pretty much ideal for all types of pool, there are some factors that must be considered before deciding to install one in your very own swimming pool, since a system costs a substantial amount of money. The actual cost of the system,installation, and its payback period would depend on many factors. With that, try to evaluate your pool site's solar resource. Solar heaters are usually energy efficient and low maintenance but it will do no good without sufficient exposure to sunlight. Also, have its actual size measured to buy a heating system that is proportionate to its size. Determine the working efficiency of the solar pool heater that you intend to buy. Then compare the system costs of the heater systems that you intend to buy and consult a trained solar technician for advice and additional information. After doing you homework you should end up with the most effective solar pool heater and be on your way to substantial long term savings.

why are solar filters for telescope so expensive?
what are they made/coated with that makes them so expensive? I'm also wondering what the difference is between the glass mirror plated filters and the tinfoil-ish ones, and why most of the tinfoil-ish ones look so flimsy (they're really loose and the material curves over itself) like this one
http://www.telescopes.com/general/celestronsolarfilterfornexstar6se.cfm?TID=CELE291&source=channel_intelligence_gbase&ci_src=14110944&ci_sku=CELE291
shouldn't it be pulled at least semi-tight so it looks like a flat filter instead of an overpriced ring of tinfoil in a plastic barrel?...shouldn't it look more appealing and professional like this one?
http://www.adorama.com/KDSC11OA.html
The problem with full aperture filters is that they must be made from material that meets the same optical standards as the telescope's optics, better than a quarter wave. Ordinary window glass is hopeless. Even plate glass is less than perfect optically. Baader AstroSolar film is a thin very even molecular film, and has by far the best optical characteristics. If it is stretched tight, it loses its optical uniformity, which is why it is loose in its cell. Celestron's filters use Baader film, and the cells are made of plastic. I much prefer Kendick's filters, which are made of powder coated aluminum. I have three of these for different telescope, and they are well made and excellent optically.

Combined multiple particle sizes of titanium dioxide, zinc oxide and iron oxide. Special formula that is perfect for photo-sensitive individuals. Fallene Cotz SPF 58 sunscreen combines multiple particle sizes of titanium dioxide, zinc oxide and iron oxide to offer excellent full-spectrum protection. The Full-Spectrum Sun Protection Fallene, Ltd. produces the most complete full spectrum sun protection available. Cotz SPF 58, Lipcotz SPF 45, Clear SPF 65, and Tinted SPF 60, all combine multiple particle sizes of micronized titanium dioxide, zinc oxide and iron oxide to form a complete barrier from the light spectrum, including UVA/UVB. The Cotz SPF 58, as well as the other Fallene products, are specially designed for photo-sensitive individuals, but are perfect for anyone concerned about maintaining healthy skin and promoting the integrity of their immune system. The Dangers of UVB Wavelengths SPF rating does not adequately measure protection from all the damaging radiation effects of light. SPF is only a determination of protection from one specific wavelength of ultraviolet radiation, the UVB (290nm - 320nm). Unfortunately, there is no currently approved standard to rate the quality of a sunscreen's UVA protective capabilities. UVA (320nm - 400nm) is the deeper penetrating wavelength that is more often associated with skin changes, such as wrinkling, pigmentation, and long term damage. The SPF rating system does not accurately or completely define a sunscreen's protective capabilities from harmful ultraviolet radiation, except the UVB wavelength. UVB creates a red, painful irritation first experienced during early sun exposure, but UVB is not the only ultraviolet wavelength damaging to the skin. In fact, UVB has only a minimal effect upon the deeper depth of skin. UVB and UVA radiation are both recognized as causing skin cancer, and SPF 30 protection is just not enough. Direct Physical Photoblockers Benefits Most of the physical photoblockers are naturally occurring metal compounds (iron, chromium, zinc, titanium, etc), although some, such as bismuth, are man-made. In addition to their photo-protective attributes, these substances also assist in preventing windburns and skin damage from wind-driven micro-particles, such as dirt and grime. These physical blockers also offer a substantial defense against infrared rays in two ways. Winter, spring, summer or fall -- no matter what the season, Lipcotz SPF 45 protects your skin from harmful rays. Minimize wrinkling, skin-damage, and photo-aging with Fallene sun-protection products. First, particles that are large enough to be seen, i.e. the reflect visible light, will also reflect and refract infrared waves that are the most harmful to the skin (760nm - 1,800nm). Second, regardless of particle size, these metal-based materials act as a "heat sink" and thereby reduce the heat effect on the skin. Titanium Dioxide: Absorbs Light and Protects Skin This white-pigment powder is widely used in cosmetics. Products containing large-particle titanium have a greater opacity, which means they have greater lightening or whitening qualities. Opaque titanium dioxide is highly reflective and strongly scatters all UV and visible rays. It also reflects much of the skin-damaging infrared waves, keeping skin cooler and reducing "heat" damage that causes unwanted photo-aging. To photo-stabilize titanium dioxide it must be micro-coated with a protectant, such as silicone or aluminum oxide. Since titanium dioxide spreads poorly on the skin, another way to inhibit its breakdown is to incorporate titanium dioxide with other blockers. To achieve cosmetic elegance and usefulness, microcoating the titanium dioxide assures a good, even application to the skin. A downside of large-particle titanium dioxide products is that they produce a white, opaque appearance on the skin when applied. However, submicronizing the titanium dioxide powder, as Fallene does, creates small particles that absorb visible light and protect the skin, but they're still invisible on the skin, so you're not covered in embarrassing white salve. Transparent (sub-micronized) titanium dioxide works by absorbing, reflecting and scattering UVB and some UVA rays. However, protection against UV, visible and infrared is significantly limited when submicronized titanium dioxide is the primary protectant. Zinc Oxide: Extends Photo-Protection Zinc Oxide has been known and used topically for centuries as a skin protectant and wound-healing adjuvant and is also recognized as a mild antimicrobial agent. More than 50 years ago, zinc oxide was indicated as a block for ultraviolet light (UVB/UVA). It also reflects infrared from the skin, as does titanium dioxide. However, its ability to protect in the long UVA range (300nn - 400nm) is much higher than titanium dioxide. Zinc oxide absorbs, rather than scatters, most UVA, while titanium dioxide primarily scatters these wavelengths. Thus, formulated in combination with titanium dioxide, ultra-fine zinc oxide "closes the window" in the UVA range. Zinc oxide works to both complement titanium dioxide's protection and extend photo-protection to the skin where titanium dioxide is insufficient. The optimal particle size range for ultraviolet blocking zinc oxide (without blocking visible wavelengths) is approximately 80 to 150 nanometers (1,000 nanometers = 1 micron). Iron Oxides: Adds Color and Complements Primary UV Blocking Agents Iron oxide is used in a wide array of cosmetics to provide cover-up color. Cosmetic iron oxides are manufactured to a high purity, desired color and particle size. Iron oxide pigments for cosmetic use are micronized powders. They are available in a number of shades and tones of red, yellow, black and brown. These cosmetic pigments, if incorporated at adequate concentration and properly dispersed, not only add color, but they also provide significant skin protection from multiple wavelengths of light. Ultra-submicronized iron oxides protect against visible light waves, but also add a little color to the finished product. This allows for the addition of higher levels of infrared protecting iron oxides, while retaining the cosmetic elegance and shade of the final preparation. Submicronized iron oxides block ultraviolet rays, which is a great complement to the primary UV blocking agents. What's in the Box Fallene Cotz SPF 58 water-resistant sunscreen tube (2.5-ounces). Ultra sensitive skin? No need to hide inside. Many dermatologists recommend COTZ Sunscreen, the most protective sunscreen available for people with skin conditions and extreme sun sensitivity, even kids. Fallene COTZ SPF 58 Sunscreen delivers broad spectrum coverage through finely micronized titanium dioxide and zinc oxide. And because it's an oil free SPF product, made without dyes, fragrance, or chemical sunscreen filters, it won't irritate skin. Features
