This website is dedicated to those, who wants to generate their own electricity for their home and business.

To our planet, and the people which still have no access to an adecuated electric energy service. This website, was created to let them know that YES-THEY-CAN have, access to a clean electric energy and enjoy a more comfortable and better life.

Fact: The sun is our first source of energy dating back as humans have existed on this planet. It is our nearest star and without it, life would not exist.

Using the sun in our daily life

Our Sun is about 5 billions years old. Only when it run out of its fuel, hydrogen; this gigantic nuclear reactor will be extinguished. It can give a developed nation as much as eighty times as much energy as is actually consumed. The Sun shines a different numbers of hours on different part of the earth, fewer at the poles, more at the equator. Also, the climate of a specific region also plays a role. On a certain latitude, clouds or fog in one region may obscure the Sun more frequetly than in another region. Its light and heat make the plants grow and thereby supply the base of existence for animals and humans.

A very simple example of how we use the Sun as a source of energy today is, when we hang our clothes after washing it outside to dry, we are using the Sun's heat to dry our clothes free of charge because we do not receive a bill for this service. This is a good sign for governments to make a solid research and investment in solar energy, including those nations who depends on foreign oil.

Note: The infuence of the sun also appears in religion like the Incas of Peru, Buddhism, the Aztecs of Mexico, The Druids of England and many native american tribes

Solar water heaters were being used all over the United States at the end of the 19th century. In 1897, 30 percent of homes in Pasadena, just east of Los Angeles, were equipped with solar water heaters. By then this technology continued to expand on states like Arizona, Florida and many other sunny parts of the United States.

Later, large deposits of oil and natural gas were discovered in different parts of the globe, and solar water heaters began to be replaced by a cheaper heaters burning fossil fuels. However, today we are facing a big crisis with oil and gas, prices is getting higher and political crisis are just hitting hard on nations that export oil, so solar water heaters are making a comeback. There are more than half a million of them in California alone and some under-developed nations are starting to experiment with solar energy. It Will be a very good idea for poor nations to start investing in solar energy because the oil crisis will affect them the most.

The biggest source of light we know.

On average, the Sun shines 3,752 hours per year on Phoenix, Arizona, it shines 1,875 hours per year on Tokyo, Japan; in Hamburg, Germany it is 1,500 hours. In the central Asia Turkestan, the Sun shines about 1,800 hours per year.

In the beginning of the 1960s, the largest solar power station in the world was built by soviet engineers. 1,293 mirrors, each 5 by 5 meters in size and comprised of 28 individual mirrors, reflect the Sun into a boiler that generates steam for a turbine. This drives a generator that makes 1,000 kw (=kilo watt; equivalent to the power of 20 midsize cars) for the electrical grid. Additionally, with the hot exhaust steam from the turbine, 20,000 apartments are heated in the winter. To follow the position of the Sun, the mirror are mounted on railcars on 23 tracks. The outermost track is 500 m from the boiler.

Changing sunlight directly to electricity

A method some engineers are using is the use of solar cells. Also called photovoltaic cells or PV cells for shorts, can be found on many small appliances, like calculators, and even on space craft. They were developed in the 1950's for use on U.S. space satellites. they are made of silicon, a special type of melted sand. When sunlight strikes the solar cell, electrons are knocked loose. An electron imbalance is created and when the two surface are joined by a connector, like a wire, a current of electricity occurs between the negative and positive.

The electrical energy from solar cell can be used directly and the dependency of foreign oil can be reduced by 50 percent or more. The only big obstacle we face today is in the use of batteries to store energy, however a lot of work is actually being done on this field, and soon we are going to see a lot of homes using solar energy to power every appliances that need electricity.


This is a hand made power reading panel. With this instrument, is possible to read the current in amperes and the voltage
produce by the solar panel(s), the battery or bank of batteries, and the AC/DC inverter.

We are currently experiencing a very difficult time. It is a difficult time for our economy and a continued nervousness about the possible disruption of energy services, adds to our everyday lives, not because we have an inefficient service (U.S.), but a possible punishment by Mother Nature.

These graphics below, show a small solar power station in a studio. Up on the roof is a 50 watt solar panel, which provides 2.5 amp of current, and, connected to a controller and a bank of batteries, power a few DC appliancest, in case of emergency. Inside the cabinet are three 35 amps batteries connected in parallel. The designer uses this little project named DSPS-1 to power 3 light bulbs and a 12" fan. The project is expandable.

      

This is an example of how we might be less dependent on energy that we buy to the electric company, which each year increases the rate, making our life a little more difficult.

We can not predict the future, however, energy experts and environmentalists are advising that it is time to seek energy alternatives in regards to keeping our planet healthier. Moreover, we should prepare for a possible energy crisis. In dspsone.com you as a visitor, will have the opportunity to meet and share with us ideas and projects of this form of energy for use in your home or business.
