The two ways the light of the sun can be used are categorized as passive or active. The passive techniques include building methods that use materials that have thermal mass with light dispersing components. Space inside a building can be designed to circulate the air in a natural way. Solar energy, used actively collects the sunlight using Photovoltaic panels.
One active method uses photovoltaic panels built on roofs to collect sun power and convert it to electricity. If the home is in a warm climate state, that can provide all the power needed in the house. In cold climate states such as massachusetts, the homeowner must be connected to a grid. That way he can purchase power from the local electric company in the winter.
Several generations ago, the average homeowner could not afford to have installation of the panels done. The cost has decreased with increased demand and production to meet that demand. The initial investment pays off because it remains functional for twenty years or more.
In addition there are government subsidies available for those who meet certain criteria. The savings can be in the form of paying for part of the installation, or giving a tax deduction to the family that owns the home. Over the twenty five year period, those panels can result in significant savings.
Although there are 174,000 terawatts of radiation transmitted from the sun, only fifty-percent of that amount reaches the ground. Thirty-percent is reflected upward into the atmosphere. The remainder is absorbed by oceans, ground and the clouds. The temperature rises as a result.
Solar energy is a concept developed by a famous United States inventor. Frank Shuman was an engineer who built a small sun powered engine. It reflected the suns energy into square boxes of ether. This in turn powered a steam engine.
Along with a British physicist, he went on to develop a more advanced system that used mirrors. By 1913 they had built the original thermal power station, located in Maadi, Egypt. Development of power from the sun was curtailed by the discovery of cheap oil in 1930.
Two decades from now the kids of today will be the inventors of the future. If they grow excited about alternative energy who knows what they will be able to do. As they see the large orange signs along the freeway, explanations about how they light up will pique their interest.
New designs are being tested all the time. Consider the lines of clothing that utilize solar energy to recharge cell phones for campers and hikers. T-shirts and caps have mini-photovoltaic panels on them. Boats and cars also have these panels to use sun power instead of petrol to fuel the engines.
Do you know about the World Solar Challenge held in Australia? It is a race entered only by cars running on energy from the sun. That country also has a passenger ferry in Sydney Harbour called the Solar Sailor, which runs on sun, wind or battery power. It can run on diesel fuel, but only on cloudy days.
Researchers are discovering new ways to use solar power every day. It is a field that is exciting. The children will someday become scientists, researchers and inventors. They may start by inventing things that run on sun power and enter them in the science fair at their school.
