Solar Cars


People think that solar power cars are only a thing of the future. Yet, they are right on the horizon for use on the highways of American and other countries. Each year, the solar power cars that race across various countries prove that the concept is viable and can work for everyone.

The idea at this time is not to do away completely with other fuel sources for cars on the world's highways. Simply supplementing the use of traditional fuel will save both the environment and the economy a great deal each and every year.

Today, the solar power cars used in the races are run only on solar power and therefore are rather odd in appearance. Because they are designed to collect the most solar energy in order to gain the speed and obtain the efficiency desired, the solar cells are large and often cover the entire vehicle. In commercial applications, however, the solar cells can be much smaller and rather well disguised to make the vehicle attractive as well as efficient.

Solar Powered Fountains


Some very beautiful solar powered fountains are available on the market today, and these are a great way to introduce new features to your garden without the use of additional electricity from the mains power supply.
The main advantage of solar powered garden fountains is the ability to leave them switched on constantly, without worrying about how much electricity they are using.
Regular water fountain pumps can consume substantial amounts of power from your electricity mains, when used for long periods of time, so a solar garden fountain is a great alternative to a mains powered solar fountain for your garden.
For the more experienced gardeners and general DIY fanatics, you may be interested in building your very own water fountain powered by the sun.
If this is the case, you may wish to see the related links to other websites at the base of this page.
Powering a garden fountain can be quite tricky in many situations as the running of underground cable can be quite expensive, and the laying of overground cable can look messy and be unsafe.

Solar Energy at Home


Energy efficient homes that go easy on the environment are turning heads in Georgia with their low-maintenance appeal, cost efficiency and natural good looks. With Georgia Tech's recent success in the 2007 Solar Decathlon and world-class community projects like Atlantic Station, Metro Atlanta is well on its way to being a model of eco-building in the Southeast.

Georgia's green power was most recently demonstrated by Georgia Tech at the 2007 Solar Decathlon. The innovative contest, sponsored by the US department of energy, is a green building competition with an emphasis on solar energy. Twenty teams from universities all over the world were handed the task of building the most attractive and energy-efficient solar-powered home they could imagine.

Over the five day judging period, the Decathlon Homes had to demonstrate the ability to use nothing but solar energy to power a washer dryer, oven, TV, computer and generate hot water. The homes also had to be architecturally sound, marketable and they had to look good.

Though it was their first year to participate in the contest, the Georgia Tech team won 6th place for their innovative light-house, a completely off-the-grid solar powered home. First place went to a team from Darmstadt Tech in Germany. Though the Georgia Tech team didn't take home first place this year, the house is part of the significant contribution that that Atlanta's architects and engineers are making to what we know about building smart.

Solar Energy Equipment - "Solar Battery Charger Unhook Us from Grid Outlet"


Solar battery charger is one of these devices that became a necessity once we have all these electric devices that we use on a daily basis. Ipod, laptop, mobile phone, PDA, GPS etc' just name it. The more we use these battery based gadgets, the more our lives in the 21st century depend on. These battery-based portable electric devices need to be recharged pretty often which hook us to the grid outlet and reduce our mobility and portability. If we do not charge them they become useless. At this point the solar powered battery charger gives us back the freedom and releases us from being chained to outlet grid in order to charge our batteries.

Solar battery chargers are not a matter of fashion, they are gaining popularity with very good reasons. Solar charger is simple to use on the go, where ever you are, all it takes is some sunlight. There are bagpacks with solar cells on them, so they charge your batteries while you are on your daily activity without any need of your attention. There are portable flexible solar panels that you can place in your small bag and use them to charge your electrical devices' batteries when you need to without being attached to any electrical grid outlet. Most solar chargers are equipped with plug kits which match to variety of electric devices. The variety of solar chargers' sizes, shapes and uses continue to grow rapidly.

There is no usage cost when using a solar battery charger as opposed to the utility electricity charger. No pollution is released to the atmosphere when using portable solar charger and no chemicals are being leached into our ground water when discarded since we are using rechargeable batteries, so you contribute to keep environment clean, not to mention that you save money when you use a solar powered charger.

Solar Energy Is Free But Can You Afford The Cost Of The Equipment


With a major emphasis placed on the ever increasing cost of energy to heat and air condition a home consumers are seeking alternative means to bring the cost of energy down and ease up on the planets natural resource supply. It seems that (Direct) solar panels for harvesting the sun’s solar power are the most familiar and commonly researched source for energy today. This is probably due to the idea that the cost of solar energy is free for the taking but the cost to collect the energy is not.

During our latest energy efficient home project we researched the viability of adding Direct PV (photo voltaic) solar energy to the home. This is what we learned after careful and lengthy consideration—it was not very cost effective at the present time even after we calculated in the grants we could get. The following are some of the reasons for our determination:

Energy Efficient Home Your Energy Costs Are Going Through The Roof


“A chain is only as good as its weakest link” when restated for home energy conservation purposes is: A home’s energy efficiency and comfort is only as good as its’ thermal package. The thermal package is everything
between you on the inside of your home and the outdoors which helps you to maintain the temperature you find most ideal or comfortable. The material most common to creating this resistance is known as insulation. Insulation is measured by its’ depth or thickness and is calculated to effectiveness by its resistance to temperature differences on either side of the insulation commonly referred to as the “R-Value”. The R-Value is described by a number where the higher the number the more resistance there is to transferring the temperature through the object. In this case the object is the home.

Let’s start with the top of the home which is the most important. In the winter, after a snow look to the roof tops to see how long the snow stays on the roof. If the snow clings to the roof the home is better insulated than the house whose roof has melted the snow off. You are looking for signs of a well insulated attic or roof. To determine if a home has a well insulated attic when it is not snowing go and check the attic to see if it has any insulation, how much and its’ condition. If the insulation is matted the R-Value, the amount of resistance is diminished. Check to see that all areas are covered verses just spotty applications. An attic that is only partially insulated is like going outside without a hat on a cold winter’s day.

Commercial Solar Power Systems


Everybody these days want green forms of electricity, one of the strongest contenders in this industry is commercial solar power. Solar power can save you money, but not just that it can actually make you money! You can actually sell the power that you generate to others that are connected to the power grid. The government is trying to encourage commercial solar panels through the SPS (Solar Power Solutions initiative). This encourages both businesses and homeowners to sell excess solar power back to the grid.

The different solar power initiatives all focus on increasing the number of solar panels, offering financing, and educating people how to use them. Solar power is becoming much more viable energy source. Businesses, home owners and even businesses are becoming interested in generating power in this fashion.
