What Happens When You Change Your Roof? – A Feng Shui Perspective

Houses can and do outlive people. And periodically, a house will need a new roof. Professional roofers suggest a new roof every 20-30 years. In classical Feng Shui, we know that the interior energy of a house is captured when it was built and specifically when the roof has been installed to close out the direct energy of the Sun into the house. During the building process, the roof may go on before the ceiling or ceilings in the case of a multi-storied home.

So, a common question amongst Feng Shui clients and students is whether or not the removal of the roof will change the inherent and semi-permanent energies inside the house. The answer to this question is multi-faceted depending on a number of circumstances. But for the most part, if a roof is removed while leaving the ceiling intact, then the original energy of the house will not change or “escape.” These are the kinds of things considered also when a person adds on a second story and how they do it.

We call this energy the flying stars, or the flying star chart for the house, which is a combination of energies from “heaven” above and “earth” below. It is a merging of time and space components which ends up having a profound and continuous effect on the people who dwell in the house or building.

A ceiling will act as a second roof, so unless a major portion of the roof and ceiling are removed together at the same time, you will not see a major change in the interior energies of a house. The same holds true for an ordinary small skylight, even though both the roof and ceiling have been cut open. If it is a small opening, and not of atrium size, then this would be a non-issue.

As well, now that people are adding solar panels to their roofs, people wonder if there will be any Feng Shui influence one way or the other and I do not think there is. In fact, when it comes to adding solar panels to a roof, it would be considered less of a “construction sha” situation than actually removing a roof, which is more of a disturbance to the area.

There are still some well known practitioners who say that you can change the flying star chart of a house by removing a couple of roof tiles. I would disagree. There was also one very famous author who said that if your roof tiles are blue in color that you will meet with some serious misfortune. To be blunt, I think this is not true at all. But everyone should know that the real goal in receiving Feng Shui advice is to empower a person with a larger skill set for controlling one’s own destiny, and not to scare the pants off of people. Very rarely will one real or perceived Feng Shui flaw cause a serious mishap or disaster in a person’s life. There would usually need to be an accumulation of many things off balance and for some time before the momentum could build into manifesting any event of significance.

Solar Aeration Is the Answer To Increased Profit In Shrimp Farming

Solar aeration is the answer to modern shrimp farming. Modern shrimp farming really started in the “Reagan era.” Marine shrimp are farmed in dugouts, impoundments, ponds, raceways and tanks. Today over fifty countries have shrimp farms. With the increasing cost of electricity and the greenhouse gases it causes, all shrimp farms need solar aeration to replace the electrically operated aeration systems. Shrimp are no different than any other living creature; they need oxygen, clean water, and sunlight. They grow faster in warmer climates where you can sometimes produce three crops a year if you are near enough to the equator.

The leaders in shrimp farming in the Eastern Hemisphere are Thailand, Vietnam, Indonesia, India and China. Malaysia, Taiwan, Bangladesh, Sri Lanka, The Philippines, Australia and Myanmar also have large shrimp farming industries. Mexico, Belize, Ecuador and Brazil are the leading producers in the Western Hemisphere. There are shrimp farms in Honduras, Panama, Colombia, Guatemala, Venezuela, Nicaragua and Peru. The United States, Western Europe and Japan are the major shrimp importing nations. They have high-tech shrimp farming but their production is insignificant. Saudi Arabia and Iran produce the most farmed shrimp in the Middle East.

Shrimp farms use a one or two-phase production cycle. With the one-phase production cycle the shrimp spend a short period in acclimation tanks, then they are put directly into the growout ponds. Farms that use the two-phase production cycle stock juvenile shrimp from hatcheries in nursery ponds and several weeks latter transfer them to growout ponds. The shrimp need aeration in all phases of growth and solar aeration is best answer. Hatcheries sell two products: Nauplii, which are tiny, newly hatched, first stage larvae, and postlarvae that have already develop through the three larval stages. Good aeration produces clean water and healthy nauplii, postlarvae and shrimp. Solar aeration is the best investment for any shrimp farm and is available now.

Shrimp normally spawn at night and females may produce 50,000 to 1,000,000 eggs, which hatch in one day. The first larval stage is nauplii, which look like tiny aquatic spiders. The nauplii feed on their egg-yoke reserves for a couple of days. The nauplii then metamorphose into zoeae, which have feathery appendages. Zoeae feed on algae and formulated feeds for three to five days and then metamorphose into myses. Myses are just starting to look like shrimp and they feed on algae, formulated feeds and zooplankton. Myses metamorphose into postlarvae, which look like adult shrimp. Postlarvae feed on zooplankton, detritus and commercial feeds. From the day the eggs hatch till the postlarvae are ready to be moved to the farm takes about 25 days. To keep the product healthy, all larvae stages need adequate aeration, and solar aeration is the right answer to preserve our water quality and keep our earth green.

There are all sizes of hatcheries from home operations to medium and large-scale operations. All hatcheries need clean water and sunlight. It is impossible to maintain a healthy shrimp life cycle without aeration, which is, I repeat, best produced by solar power.

Shrimp farmers next move the animals from nursery ponds within 30 days to growout ponds. This move increases the survival rates of their juvenile shrimp and increases their profits. The greatest danger throughout the production cycle is virus problems, which can be avoided with sanitary conditions of clean water with adequate aeration. Shrimp farming, like any business, is about producing the highest quality product for the lowest cost possible, so that at the close of the business cycle there is a superior profit. Reducing electrical usage with solar aeration adds to a higher profit margin.

How Do Solar Powered Flashlights Work?

Solar power lights are rather ingenious inventions that have many uses. Who would have thought you could use the sun to power a light, or a flashlight? Solar powered flashlights are pretty cool little gadgets. They generally look quite similar to a regular flashlight. They have a simple switch that turns them on and off. They have an area on one end that emits light…sufficient to allow to be used at night or in any dark area.

A solar powered flashlight uses sunlight energy, converted into electrical energy in a solar photovoltaic (PV) cell or panel that sits on the outside of the flashlight, that is then stored in a battery. Most solar powered flashlights use LED or Light Emitting Diode lamps rather than an incandescent light bulb, as LED’s take less electrical current to operate, and they last longer. While an incandescent light lasts, on average, for about 1000 hours, an LED lasts for an average of 100,000 hours.

Similarly, solar charged batteries that are used in the solar powered flashlight, as compared to the normal, single use nickel, lithium, or cadmium batteries generally seen in flashlights, usually will not require replacement for about two years with steady use. The comparison rate is about 15 hours for a regular battery, compared to around 2500 hours for a solar rechargeable battery.

To maximize the usage of your solar charged batteries, you should leave the flashlight on for 15+ hours at least once a month to fully expend the charge. Rechargeable batteries have a memory effect. Therefore if you continually use the flashlight without ever fully discharging it, it will eventually only recharge to a lower (memory) level, and never return to 100 percent of its available power.

For best results, keep your solar powered flashlight on a window sill when it is not in use, where the solar panel is exposed to the maximum amount of sunlight. If you’re not using it regularly, be particularly mindful to turn it on…and leave it on…as described above, at least once a month.

You can find solar powered flashlights in most hardware stores today. They’re great for camping and emergency use. Every vehicle and every home should have one. If you wonder why…think about those times that you’ve needed a flashlight in a hurry only to find that the batteries were dead, and you had no spares…or didn’t know where they were!

Some amazingly innovative designs are being created for solar flashlights…with add-ons like siren, flasher, cell phone charger, etc… in addition to the basic flashlight design. There are also any number of solar flashlight key chains are on the market today. The price range varies, depending on the uniqueness of the style, the outside casing, and additional functions.

If you’re interested in “spreading the light” in a very solar way, you may want to visit bogolight.com. The name stands for “Buy One, Give One.” SunNight Solar, the company that operates the BoGoLight Program is a Limited Liability Company founded by Mark Bent in 2006. Having served in the American Diplomatic Corps in a number of developing countries, Mark saw the need for light in many places, and found a way to provide it. When you purchase one solar flashlight at BoGoLight, or through one of its affiliates, such as InHabitat, an identical solar flashlight will be donated to a non-profit who collects and ships the lights to areas of need throughout the world.

What a unique and wonderful way to “shine a little” light…in a very solar way…and light the dark for those who cannot see. Solar powered lights are the wave of the future.

Removing Salt from Water Using Solar Power

As time passes, solar power is becoming a more cost effective and flexible power source. One area where it is being used with little fanfare is desalination of water.

Removing Salt from Water Using Solar Power

It is rather ironic that the majority of our planet is covered in water, but millions of people are in areas suffering from water shortages. The nature of the irony is clear almost immediately. The oceans of the world consist of salt water, a combination we simply cannot drink.

For the longest time, there has been discussion about converting saltwater into usable, drinkable water. This process is known as desalination. If the process can be used on a large scale in a cost effective manner, it will resolve many of the water issues in the world today whether they exist in third or first world countries.

Desalination is a term used for removing salt and minerals from ocean water. The name suggests one methodology, but there are actually many. Reverse osmosis is currently the most popular and is essentially a filtration process. It is popular in countries that currently have desalination plants such as those found in the Mideast and Caribbean. The process is also gaining more interest in China and the United States where certain regions are suffering habitual water shortages.

One of the issues that arise with desalination is the energy cost. Most plants are powered by fossil fuels, although Russia is currently studying a plant run off nuclear energy. With global warming and energy price concerns on the forefront, many are now looking to renewable energy platforms as an energy source for these plants. Solar energy is one of the options.

Solar desalination plants do not work in the way you might think. Solar energy is not used to provide power to the desalination process, although it probably could be. Instead, the power of the sun is built into the system. The idea is to heat saltwater and turn it into a vapor. The vapor is then run through a condenser system that turns it back into liquid water.

Solar desalination systems work differently, but the idea is to separate the water from salt by using the natural system one finds in the oceans. As you probably know, water evaporates off of the ocean to form clouds in the atmosphere. When the proper conditions occur, these clouds subsequently turn into rain clouds and release the saltless water. Solar desalination tries to mimic the process.

The double concern of rising energy prices and global warming are stimulating research in the renewable energy field. Solar desalination represents just one area where this research is producing tangible benefits.

Homemade Solar Panels, 10 Useful Tips For Building High Efficiency Panels – The Power is in the Cell

Homemade solar panels can be made in any size with relative ease and little expense by following some simple directions. There are several steps, but the actual work is quite simple.  A solar panel is nothing more than a shallow box that holds individual solar cells linked together into an array, You can save a ton of money by building your own solar panels, but the energy is  collected by the individual cells, so using the right cells is all important.

Solar cells can be purchased either new or used.  Follow these tips and your homemade solar panels should provide years of reliable service.

1) The number and type of solar cells you use determines the amount of power that each panel is capable of producing. Each cell is rated to produce a certain maximum wattage. The combined total of these ratings will provide a reasonable estimate of the finished panels capacity.

2) Be aware of the type and size of the cells you are considering. Type and size indicate voltage and current, respectively. As a rule, higher current is achieved with a larger cell. Total power output is determined by amps X voltage.

3) Efficiency rating describes the amount of power that can be produced per square inch. Newer, more efficient cells can collect more energy than older, less efficient cells. Efficiency is important because it establishes the size of the completed panel, and available roof space could come into place (i.e. producing more power with smaller panels will require less roof space).

4) A panel’s maximum current capacity is limited by the smallest cell it contains, so use matching cells within each panel. Otherwise the larger cells won’t perform up to their rated capacity.

5) New retail solar cells are more expensive. You can get slightly defective new cells and even used ones. Don’t be scared off by terms like “defective” or “irregular”. These are often cosmetic flaws that haven’t passed the manufacturers standards and usually function just as well as any other new cells provided the defect is not too severe. Investigate and test before writing them off.

6) Handle with care! Solar cells are somewhat brittle and thin. Keep them in a safe place until you are ready to use them.

7) As a related item, if you buy on-line or through the mail, find out how the seller intends to ship them.

8) Make sure the cells you buy have tabs on them already. You’ll be glad you did when you realize you’ve cut your soldering time in half.

9) Each cell must be clean and free of film or wax before being installed. Cells are sometimes shipped with a wax coating and this has to be removed carefully.

10) Get a good instruction guide that will show you step-by-step what to look for and where to find the best sources for all your parts. This will save you thousands of dollars in mistakes, bad purchases and lost time. You’ll refer back to the guide again and again as you grow your system and will easily the small amount paid for the guide on your very first panel.

Benefits of Modern Architecture and Solar Panels

The architects of today are building homes that are greener and friendlier for the environment. Homes are designed so that they can include solar panels along with its structure. Heating up homes using solar panels rather than using gas or burning wood or even electricity has its own benefits.

Long-term advantages of using solar

As it has been made clear that the number one benefit of using solar panels is its eco-friendliness. Such renewable resource leaves out no carbon dioxide or smoke to pollute the environment. It helps in reducing pollution and in the long run, slowing down global warming. When people would use solar panels rather than traditional ways of generating electricity, lesser non-renewable energy would be exhausted and eventually, it will lessen the global pollution.

Another great benefit is the costs that are normally incurred on heating bills. After putting in the initial investment in putting up a solar-powered home, the various costs it helps reduce in the long run puts the initial amount in the back of your head. Using solar panels to heat up your home helps homeowners to enjoy a warm comfortable environment and look at less devastatingly heavy heating bills.

Modern architecture accommodates solar modules

Although, the homes of today are being designed strategically so that maximum amount of space is given with huge windows and glass doors, this eventually helps the sunlight to filter in through various spaces. One advantage of that is people can keep their plants inside their home and yet they won’t wither or die because of consistent presence of sunlight. Their nutrients required to keep them thriving are present just because of the architecture of the house. This adds certain elegance to the home as well. Also, it gives one’s house a more spacious look – one of welcoming and brightness. This way, fewer lights are required to be lit, saving more electricity for the night-time when the sun is not present.

The History of Solar Panel Battery Chargers

The history of solar power battery chargers has to begin with the advent of solar power. Attempts to capture the power of the sun have been made since the dawn of man. Realizing its power to give heat and light, intrigued man from the beginning of time. Leonardo da Vinci studied the sun and ways to harness it in the fifteenth century.

Although modern science has taken away the romance of sun gods, mystical beings and other myths and tales, it has not lost its curiosity. Harnessing the suns power to be used in batteries has been around since France decided it needed an alternate energy source long before the fuel shortage of the seventies.

Charles Fritz managed to turn the suns rays into electricity with the first solar cell in 1883. It wasn’t until later in the 1880’s that a solar cell was used to warm water in his house. The studies went on. The possibilities of using up all of the nonrenewable resources was well known in the nineteenth century. People around the world still chose to use coal and other nonrenewable energy sources as though they would never end, or have any consequences.

Three scientists from Bell Labs, Calvin Fuller, Daryl Chaplin and Gerald Pearson made the discovery that silicon was a very good semiconductor. Today solar cells and panels are usually made of silicon.

These small yet applaudable steps were baby steps to the many uses of solar energy today. Now, solar energy is influencing the production of energy much more than those in history ever imagined. It is no longer history, it is the future that depends on solar power and the ability to use the sun as an energy source and to not deplete the earth of nonrenewable resources.

Then the price of oil doubled in the seventies, the government of the United States finally decided to invest time and funds into the development of the solar cell. This is the same solar electric cell that was produced in 1953 by the scientists at Bell Laboratories.

Today the assortment of solar powered battery chargers is amazing. When you inventory your electronic gadgets, you know that everyone needs to be charged in one way or another. You will find out that most of those electric chargers can be replaced by solar battery chargers.

The solar charger contains solar panels. When these panels are placed in direct sunlight, the panels will convert the energy from the sun and store it in your battery. The more energy you want, the larger the solar panel you will need. Portable solar chargers are available and built into many small devices. Solar powered calculators have been around for decades. At first large and cumbersome, they are now pocket sized and more efficient.

Internal solar batteries are usually what you will find in these small hand held devices. Price counts. There are some that are too small to charge the device with just the sun, but can charge the internal battery. Internal batteries will most likely have to be replaced before the device wears out. Replacement of an internal battery will most likely occur every couple of years and is a danger to the ecosystem. A weak battery in a new device is also a potential issue.

External solar chargers are great when you aren’t anywhere close to an electric outlet. You can plug the charger into your device on a beach, in a foreign country or out in a boat with no AC power. They are also great if you are camping. You can get solar panels large enough to keep everything in your camp charged and usable without tapping into electrical power supplies. They are great for any emergency, survival or your pleasure when electricity is not available.

Before you invest in a solar charger, it will be important to see if your appliances and devices can be used with one. The additional purchase of cables may be necessary in some instances.

In order to charge rechargeable batteries you will need a separate solar power charger. Since this will most likely be used outdoors, it is important to buy one that is weatherproof. Keep the connections clean and free from anything that may clog them and the panels themselves will function more efficiently if they are also kept clean and free from dust and grime.

Advantages of Solar Powered Water Filter Technologies

With ever-increasing rates of fuel, we need to find renewable sources of energies. Solar energy is one of the natural solutions that are gaining popularity these days. Energy of sun can be utilized in many ways. Harnessing solar energy is free from any kinds of damage and pollution and can be used for everyday needs.

Solar powered water filters are one of the efficient technologies that can replace the machines that require electricity for its working. With minimum input, water solar water purification systems offer drinking water that is healthy and safe. With choice of portable and stationary solar water purifiers available, you can purify water anywhere without any need of being attached to grid. These filters can be used for residential purposes and for large industries.

Solar powered water filters operate with the help of natural energy given by sun that is gathered through solar panels and then converted in the serviceable energy. Solar panels are placed in the direct sunlight for the optimal efficiency, which makes these water purifiers ideal for outdoor activities like camping. Maintenance of these solar powered purifiers is also simple, as they do not demand use of batteries, moving parts and external electronics. As these filters just need sunlight for their operation, they do not need much cleaning.

There are different applications of these solar purifiers. Just as boiling, these distillers help in getting rid of the contaminants. Solar power heats up the water and makes it fit for drinking. Water is heated until the time it starts evaporating and solids and containments are left behind, pure water is received. Portable solar purifiers can distill as well purify from the natural water resources like streams and lakes. Some models available in the market use batteries and solar energy so that charge can be reserved, letting you have an opportunity to use the purifier anywhere, anytime. Solar powered filters can give you larger yield as compared to standard electricity filters.

In case you need more charge, you can hook the solar powered filtered to car or other power source and still can operate by using sun’s energy. Portable solar water filters are a savior in emergencies like earthquakes and floods. They are used for transforming dirty water into pure and clean water for drinking.

Large water purifiers that use solar energy make use of same technology and clean up to hundred gallons of water everyday. Larger gallons can also clean up to thousand gallons a day. Just as portable purifiers, these water purifiers make use of secondary sources of energy like generators but mainly rely on sun’s energy. Communities in various parts of the world are creating homemade solar powered water filters for providing healthy water to their neighbors as well as their own families.

Many places are not connected to clean and healthy water lines, various methods are used for transforming it into natural and less polluted sources of water. All of us require clean water for staying fit and there is no better way to clean the water than solar water purifier.

The Emerging Technology of Solar Power

Right now, the best solar panels can reach a peak efficiency of about 15-20%. This is due to the fact that our current solar technology does not allow the panels to use all available wavelengths of light. For example, in a ray of sunlight, there are many different wavelengths. Many of these we can’t even see with our naked eye. The same goes for solar panels.

Sunrgi, an Israeli based solar panel company, has developed a “concentrated” solar cell that can multiply the wavelengths of light to produce much more solar power on a smaller system. While the company is keeping a tight hold on the technology that allows this advanced solar energy, they predict their new panels will produce a kWh for a mere 7 cents. For the average household, this equates to an electric bill of around $80 per month! This beats what most Americans pay now- well over $200 a month for electricity. Better yet, Sunrgi’s new panels convert a whopping 37% of sunlight to usable solar energy! This is more than double the industry standard. Sunrgi is expecting their first panels out by mid-2009.

The University at Tel Aviv is also making huge advancements in solar panel technology. Researchers there have scrapped the idea of using semiconductors within their solar cells. Instead, they have genetically engineered “proteins using photosynthesis for production of electrical energy”. Commercial production of such a technology is several years down the road, but these panels would cost 100x less than conventional silicone and could produce an efficiency around 25%. This makes these panels very attractive to poorer countries that want to go solar but cannot afford conventional silicone panels.

Another promising technological advancement is the increase in efficiency of thin-film solar panels. These thin film panels use 40% less silicone than conventional polycrystalline panels, and are much less expensive. Unfortunately, they also have less efficiency- around 6%. By the end of 2009, some researchers are estimating they will be able to produce thin film solar cells with efficiency between 8-10%. This makes then more comparable to conventional solar panels. Plus, more people will be able to buy these less inexpensive panels.

Further developments in solar panel technology are in the battery systems you can use alongside your panels. Every year, new batteries come out that last longer and store more energy than ever before. This increases the environmental friendliness of solar technology so that batteries don’t have to be thrown out or recycled as often.

Solar energy may seem expensive, but the long-term benefits are priceless. Where else can you get 25 years of reliable energy costs around $80 a month? Certainly not from your utility company. Solar energy is reliable, has zero carbon emissions and easily pays for itself within 8-10 years of purchasing. For the future of the world’s electric supply, residential solar power systems may be the best answer to a limitless resource: the Sun.
