How to Utilize Solar Energy?

In this times that our world is environmentally deteriorating, Solar Energy is a great alternative to source out the need for energy to run different kinds of mechanical devices that such would allow.

?Solar power, which we get from the sun, provides us with renewable energy that we can use for different kinds of purposes. With the use of solar photovoltaic, we can convert the light from the sun into energy we can use to make solar calculators, solar shower heaters, solar cars and just about any device needing electrical energy to run.

?We can even heat up things with the use of solar energy. Sometimes, we can also burn paper or wood with it. If you have a glass that can magnify the light coming from the sun and focus it on the paper or piece of dry wood, you can get a fire started.

?The above are just some ways of harnessing the solar power or solar energy that the sun provides. Solar energy or solar power is also used for water disinfection.

?There are even some places wherein solar power or solar energy is used to make wonderful works of art. The same method of starting a fire with a magnifying glass is used by the solar artist to create their pieces of art. They burn into their medium and create such beautiful pieces that we can use to decorate our homes.

?We also have everyday gadgets that run on solar power like the handy calculator. The orientation of buildings is also being adapted to fully utilize the light that the sun provides us.

We consume lesser electricity for our lighting when we utilize the daylight that the sun gives. Some houses even now use roofing materials for some areas in their house that would let sunlight in. This concept is also being used in big buildings like the malls. Again, electricity that would be used for the lighting the area would be lessened and the amount of money saved will be put to a better use.

When we use solar power or solar energy, we save not only on costs but we also save a part of our environment. The adverse effects of pollution are lessened when we get part of our energy requirements from the sun. Solar energy can be utilized in a lot of different ways. Check out the different information available online and have a see for yourself how you can get the most out of solar energy. Solar power is truly one great source of energy that we can use and at the same time help mother earth.

Utilizing Solar Energy – How We Can Make The Future Bright

It is believed by many experts that sun is the most powerful source of energy. It can do anything right from heating the rivers, pools, lakes and ponds. It is as simple as leaving the clothes outside for drying. Despite all this known fact we have not been able to harness the sun’s energy to the fullest and use it efficiently.

Scientist thinks that this is best source of renewable energy. It is in abundance and has been with us for many years. Most importantly it is safe and can be used world wide. When the sun’s light strikes the earth it generates heat and this energy can be utilized for the benefit of human kind.

The sun’s energy is being used all over the world. Sun as such provides a heat source which is natural. It can be used to control temperature without converting it. For using it as electricity it first needs to be collected and then converted. Thus we see that the sun energy can be used in different forms

Solar panels have been used for heating the houses. Scientists have tried to replicate the success by designing the solar powered car. They have not been successful as yet and the future for solar car doesn’t look bright also. It may take a while when we will be seeing the solar powered car.

Solar power can be captured and used for source of heat or ventilation. A thrombi wall is such an example. It utilizes the sun’s heat with the channels of air that are built between a wall and a window. When the sun heats the area and circulates through the vents it stores the heat. The same stored heat is utilizes during the night.

Thus we see that solar power is not only efficient but also dense. It can be replicate across the earth and it does not require any maintenance. So operating cost is minimal.

Australia is among few countries which have used solar power to generate the electricity. It has around 40,000 locations in the town of Victoria where clean solar energy is being generated without any emission.

PV system is other area where solar energy can be used. PV systems are the system where it is connected to an electrical grid and when the energy becomes excess in one grid it gets transferred to the next grid. Thus it is both effective and cost efficient.

So its our duty that whenever possible we should use the sun’s energy. As it does not pollute the atmosphere so we will be doing ourselves world of good by harnessing this wonderful energy source and using it. Thus we will be helping ourselves and the mankind.

Solar Powered Vehicles – Alternative Energy Sources

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.

Solar Cars: The Oldest Energy Around

With zero emissions, solar cars present a sunny solution to eco-friendly car buyers. It also makes good sense to develop a green car technology that doesn’t call for a complicated infrastructure or any type of fueling station. What could be easier than using an already existing energy source like the Sun, right? After all it was around since the beginning of the solar system, well before fossil fuel. If it were only that simple, we’d probably already have done it. In spite of universities and corporations building solar cars every year for the past 20 years for the annual Australian World Solar Challenge solar car race, we’re not quite there yet.

How do they work?

A solar car is really an electric vehicle powered by solar energy. Photovoltaic (PV) cells in the form of solar panels convert sunlight into electrical energy. The process generates heat, which is converted into electrical energy and stored in an on-board battery. The battery serves the same basic purpose as a gas tank on an internal combustion car.?

In spite of the great bounty of sunshine there for the taking, solar car technology is elusive. The solar electric power source needs a lot of PV cells, which are expensive, and the efficiency level of PVs is estimated to be only 10% to 15%. These are daunting challenges facing engineers, and it’s more likely a hybrid solar with another fuel source is the only viable option in the near future, yet the concept is intriguing enough for engineers inside and outside universities to take a pure solar car prototype into a more advanced development stage.

Are there any solar cars out there?

French manufacturer Venturi says their solar electric AstroLab hybrid concept car yields an improved PV cell efficiency level of 21%. It’s not exactly a family car with its 2-seat tandem cockpit configuration, but it’s one possibility. The Hungarian manufacturer Antro has designed a solar gas-electric hybrid other wise known as a tribrid scheduled for production in 2012, and Tesla Motors has an electric car that can be recharged with solar power with 2009 models available in the U.S. and Europe. These are only the first advances in solar car technology. As time goes on more and more manufacturers will be developing and incorporating some type of solar technology into preexisting propulsion systems. This will create a new sort of hybrid, disconnected from fossil fuels, yet still not fully reliant on the Sun’s energy

Perhaps with the recent high intensity photvoltaic cells designed by a company in Israel, many of the energy efficiency problems will be taken care of. It is not clear though if they can be designed for cars.

Conclusion

Solar energy and more specifically solar cars would be an amazing advancement in future car technology. They would allow for free travel and nearly unlimited accessibility. Time will tell if all the problems associated with harnessing the world’s oldest energy source can be dealt with. If the hurdles can be passed then for sure solar cars will be the wave of the future.
