The light from the sun is a renewable source of fuel that is either passive or active. Passive ways of capturing it include construction that uses materials with light dispersing components. The interior of a home can be designed to cause air to circulate naturally. There are also active ways to use solar energy.
The homeowner with photovoltaic panels on the roof will also have to be connected to a grid. It will enable him to get electricity from another source, such as a local electric utility in the area.
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.
For some families, depending on meeting certain criteria, there are government subsidies to help cover the cost. There may be rebates or tax deductions offered in return for having the installation done. This makes it affordable for most homeowners.
About fifty percent of light and heat emanating from the sun reaches the surface of planet Earth. Of the 174,000 terawatts of incoming radiation, thirty percent is reflected back into space. Clouds, oceans and ground absorb the rest. This absorption serves to raise temperatures.
A famous United States inventor developed the concept of using light from the sun to convert to electricity. This engineer, Frank Shuman built a sun powered engine. How it functioned was by reflecting the energy from the sun into small boxes of ether. The resultant power ran a steam engine.
Together with a British physicist, Sir Charles Vernon Boys, Shuman developed an advanced system using mirrors. They built the original thermal power station in 1913. Development of solar power was curtailed when cheap oil was discovered in the early 1930s.
The schoolchildren of today are the homeowners, scientists and consumers of tomorrow. Getting them excited about possible uses for the suns power is a good idea. Do they ever ask how those big orange signs along the freeway system light up without being plugged in. Tell them about the solar panels on top of each sign.
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.
One exciting event is the World Solar Challenge, which is held yearly in Australia. The automobile race allows only cars powered by the sun. Also in Australia, in Sydney Harbour, there is a passenger ferry named the Solar Sailor. It is powered by the sun, the wind or batteries. It runs on petrol on those days it is needed.
There are so many inventions and so much research into the use of sun power. It is an exciting time. Who knows, some kid might enter a sun powered robot in the next science fair, or possibly has already done so.
