What is a Sun Shard?

admin — Fri, 07 May 2010 07:57:10 +0000

Ok you White Wolf WOD Garou gamers, listen up. I’ve misplaced all my books and I need to know, in detail, how a Sun Shard is used, I need to know its Gnosis level, how it’s activated, what kind of damage I can expect it to do, all that jazz. I need to know everything you can tell me.

While you’re at it, does anyone know anything about a bad guy called Lady of Night? Probably just an ST imagination thing, and no, I am NOT power gaming.

How To Solar Power Your Home

admin — Fri, 07 May 2010 07:57:05 +0000

For centuries we have used the sun’s natural energy to our advantage. For example, it has been used in ancient times to provide natural lighting in temples, for photosynthesis and natural heating for growing crops, to desalinize and purify water, and it has been magnified and intensified to heat thermal power plants.

So, how can solar power be used on a smaller scale at home as clean source of energy?

Basically, there are four main ways how to solar power your home:

Passive Solar Design:

To think that Americans consume up to 50% of their energy to heat, ventilate and air-condition their homes, a large amount of money and energy could be saved by using passive solar design at home.

Passive solar design is the strategic use of the sun’s energy to heat, light and ventilate your home naturally. For example, having a home that faces the sun, that has large, low-emissivity windows, and that is built from heat-retaining materials will tend to be naturally warmer in winter.

And like the Romans used the sun to light up their temples, careful placing of windows and mirrors in our homes can increase natural lighting, helping us reduce the need for electric lighting.

A natural air conditioning solution would be to plant deciduous trees on the sun-facing side of your home. This would provide cool shade in summer, but allow warm sunlight though in winter.

A solar chimney can be installed for ventilation, where the air in the chimney is heated by the sun and rises, causing fresh, cool air to rush in through the home and up the chimney.

Solar Cooking:

Solar cooking is the cleanest and cheapest way to prepare food. Although it is widely used in third world African countries, where fuel and electricity is not readily available, there is no reason we cannot use it during summer at home.

A solar cooker is made from a series of reflective panels in a parabolic shape that focus the sunlight on a box or pot, in which the food is cooked. It usually caters for up to five people, and can make a variety of boiled, roasted and baked dishes.

The one drawback of solar cooking is that it tends to take three to four times longer to cook food in. But if you weigh that against the unlimited power savings and its portability, having a little patience is not that bigger deal.

Solar Water Heating:

Solar water heating has a number of uses, and thanks to technological developments, modern solar water heating systems can be used at home to completely replace conventional boilers or geysers.

As cold water is pumped through a solar collector, the pipes absorb the sun’s energy, and heat the water, which is then stored in an insulated tank for later use. Usually the water can get so hot that it has to be mixed with cold water before it can be used.

Solar Electric Power:

Also known as photovoltaic power, many homes are starting to make their own power at home with solar electric panels. These panels are made up of small silicon cells and need to be directly aimed at the sun to be most effective.

As the sun’s rays penetrate the solar panels, electrons in the cells become charged, creating a current that is stored in deep-cycle batteries. When electricity is needed, the stored power is passed through an inverter to change the DC to AC, which can then be used to power various household appliances or connected to the grid for net metering.

Other than providing you cheap, clean renewable power, solar electric panels have become affordable and simple enough for anyone to install at home. In fact, with the right information it is possible to make your own solar power for under $200, as compared to getting a professional installation for a couple of thousand dollars.

With these four ways on how to solar power your home, there is no need for you to rely on the utility companies or the government for heating and lighting at home. Right now it is very possible for us to use solar power at home. It is just a matter of everyone having the determination, energy consciousness and environmental awareness to take action and harness the sun’s free, natural power.

How much Power does the Sun radiate?

admin — Fri, 07 May 2010 07:57:04 +0000

Does any of you know how much power (in Watts, or MW, or GW, or whatever) the Sun radiates? Or could you give me a way to calculate it as a function of its temperature and radius?

Stars for the best answer!
nudnik0: Exactly what I wanted. as soon as this damn thing let me, you´ll get best answer.

laurahal42 : Why didn’t I just looked it up myself? Well…Im just lonely.

The Benefits of Solar Power Systems

admin — Fri, 07 May 2010 07:57:01 +0000

Implement quickly the idea of solar energy for homeowners was in the minds of millions of people around the world. There are a number of changes in our society. These changes are forcing people to seek alternative sources of energy. Electricity from the sun is a serious contender as the number of alternative energy sources. There are so many advantages that are mentioned on solar energy for homeowners. Hopefully, these benefits other people can convince their role sooner rather than later. Your own solar and wind power for less than $ 200 Rapidly rising electricity costs and global warming are the main reasons for the need of mankind for other energy sources. These two problems are in the sense that the cause is linked from the use of fossil fuels. The rising cost of electricity is due to the fact that the demand is always higher. On the other hand, fossil fuel supply is running low, since it is limited. The law of supply and demand is certainly the cost of electricity will be higher each year. Global warming is possible, the use of fossil fuels in context. Electrical installations with coal and oil is a major cause of gases in the atmosphere. So we clean and renewable energy sources and energy who have to look out of the sun, is one of the solutions to this dilemma. Your own solar and wind power for less than $ 200 The great thing about electricity from sunlight is that it is free, clean and unlimited. The sun is our source of electrical current. All we need to do is convert sunlight into electricity and stores it in batteries. There is even a possibility that you could have your e-generator system capable of producing more electricity than what would be your home really need. As a result of this excess electricity, you can sell it to municipal utilities and make money. The next challenge we will face is the creation of solar energy for homeowners. This is not a problem. There are many companies sell solar DIY kits on the Internet. Another great thing is that you can build solar powered the entire system for only $ 200. Yes, this is 100% true. Solar energy for home owners is like the sun really. Your own solar and wind power for less than $ 200

Solar Powered Vehicles – Alternative Energy Sources

admin — Fri, 07 May 2010 07:56:58 +0000

Copyright (c) 2008 Steven Magill

Years ago, no one ever thought that solar powered vehicles are even possible. There are solar-powered calculators or solar batteries that can run small devices but as for solar-powered car engines, many have remained skeptical until they finally saw actual vehicles that run on the energy of the sun created for exhibits in various science and technology fairs. These days, many are already considering on the possibility that, in the next couple of years, mass-market solar powered vehicles will be available to consumers in replacement for the ones that run on oil fuel.

These days, one can see solar powered vehicles in engineering demonstrations and solar car race events.

Cost-efficient

Solar-powered vehicles are, without a doubt, more cost-efficient than the typical cars that run on oil fuel. After all, these cars harness energy from something that is abundant ‘ the energy from the sun. So long as the sun shines, these cars should be able to run just as efficiently as any other type of vehicle. Because they run on solar power, these vehicles will also enjoy higher mileage and longer life spans according to most experts. Solar powered vehicles offer a lot of benefits to the potential consumers who would be willing to invest on such cars.

While solar powered vehicles are not yet practical day-to-day transportation devices, it’s only a matter of time before they actually get introduced into the market.

How they work

Solar powered vehicles literally run on the energy coming from the sun. They follow the same idea as that of other solar-powered devices such as calculators or batteries. The surface of the car has solar panels that collect solar energy. Photovoltaic cells installed in the vehicle work to convert this energy into electrical energy that the engine will need to run the car. In theory, solar powered vehicles will only run when the sun is present. However, numerous studies are now being conducted with regards to the creation of energy trapping components that will enable the car to store enough energy for it to run even at night.

Design

The design of solar powered vehicles is largely limited by solar batteries that are installed in it. Most cars that run on the sun’s energy are designed to be lightweight. Every component shouldn’t weigh as much as the ones that you would typically find in conventional cars. They do have practically the same basic parts that traditional vehicles have. You will find brakes and accelerators in them. Some even come with cruise control.

Challenges

With solar powered vehicles, the current challenge is to create a process or a mechanism that is capable of harnessing solar energy efficiently even on places with a relatively smaller surface area such as cars roofs. Solar cells are usually effective on buildings because they are always exposed to the sun’s heat. Cars will warrant more attention on this area to create efficient solar powered vehicles that can be used just like cars that run on oil fuel.

Global Warming Polar Bears

admin — Fri, 07 May 2010 07:56:54 +0000

www.simple-gold.com SolarPanels – Build Your Own Solar Panel From Kits Many people think that it is very difficult, if not impossible, to build your own solar panels. They are then turned off by the prohibitively high costs of commercially available solar power setups, even though they may be interested in alternative energy. Now, when talking about the decision to build your own solar panels from scratch, the difficulty is indeed high, and most of these projects are too small for practical use. However, there are actually supplies that are available that make it possible to partially construct your very own sun-powered electricity setup. Kits like these are complete in themselves, containing everything that a do-it-yourself enthusiast would need to build a fully functional power system for home use. Apart from yielding a working setup, these are also invaluable for teaching users the basics on how these setups work and are built. These kits are not that difficult to find, which may come as a surprise to some of you. Simply doing a little research on the Internet is often enough to turn up a couple of sources of the supplies you will need. Among these are such reputable companies as GE, which is selling equipment at reasonable prices. What good would one or two photovoltaic electric panels built from kits do for you, you may ask? Well, even if the panels you set up are not quite large enough in scale to take you completely off the power grid, they will surely help …
