Wind up Watch - a thing of the Past

June 23rd, 2009

Watches have made great advances in technology. Wind up watches were the most popular and practical system for use around the world for many years. As technology created smaller batteries, watches began using this new technology instead of tiny gears and springs. Watches with time, dates, data and other technology incorporated in them also became normal. Small computer chips which could store large amounts of data helped create a “smarter” watch.

Technology did not stop there. The invention of the solar cell has created the ability to do away with the need to replace a battery every few years or wind a watch. Solar cells are able to charge a watch indoors using room lighting or outdoors using natural lighting. Many of these watches will actually continue to function for as much a five months with a single full charge.

This makes the watch self sustaining. The owner does not need to worry about charging the watch or having the watch stop because it has lost its charge. The need to replace a battery, or rewind the watch is eliminated.

The price of these watches has become quite reasonable. Several manufacturers make solar watches. Casio, Bulova, Citizen, and Timex make watches for men and women. They come in many styles and price ranges to fit the budget or style of each person.

History of Solar Energy

December 1st, 2008

You may think of solar use as new to our century. However, the ancient Greek and Romans used passive solar in their homes. Wood to burn was often scarce, so they learned to face their houses south to catch the sun during the winter. They covered the south facing openings with mica or glass.

By the 6th Century A.D., houses with sunrooms on public buildings and houses became so popular, that a law had to be created to make sure that no other buildings blocked the sun from an existing structure that used solar energy for heat. Here in North America, the Anasazi people faced their cliff dwelling structures south to catch the sun for heating purposes as well. The Pueblo’s are descendants of these people.

During the 1800’s solar use again came into limited use. August Mouchout, an inventor, felt that fossil fuels would eventually run out. He built a solar powered steam engine. the high cost of building the unit, plus the falling price of English coal brought an end to his dream. The thought of using solar energy as a source of power still interested individuals and scientist throughout the 19th century. Solar hot water heaters came into existence in 1891 when Clarence Kemp patented the first solar hot water heater system. It became a practical way to heat water, especially in Florida and California. by 1900, almost 1600 homes had been built with solar hot water heat in California. The unit worked well during the day, but did not keep water hot over night. It wasn’t until William Bailey created and patented another water heater system in 1909 that water would stay warm over night. That system had a separate storing system for the hot water. This kept the water hot over night. He called his system the “Day and Night Solar Hot Water Heater.” Through the years, improvements have been made on solar hot water heaters, but they work similar to what was created in the early 1900’s.

Since then, other means of using solar energy have been created. For instance, in the 1950’s Bell Labs discovered that silicon could be used as a semi-conductor of electricity. This discovery paved the way for solar cells and solar panels. Today, solar power is used to supply electric to homes and businesses. Solar panels and even shingles using this technology now exist. We have appliances that use solar cells to power them. We have outdoor lighting that works very well off of this technology. It can be used as illumination or as a means to add beauty to a home at night, or both. There is an array of solar powered products that no longer need to be plugged into a wall socket. Just the sun as a source of power.

Solar powered products and ideas are becoming very popular and a good investment because after the initial cost, there is minimal upkeep. They have become a reasonable alternative to fossil fuels. Shouldn’t all of us use this natural resource? Why not join the green revolution. Help save our earth.

John Hingle has become interested in Solar energy as a reliable alternative to fossil fuels. This technology is well suited for use as a source of power for the home, office, or business. It can be used to power products that we use every day without the need to “plug them in” or use a battery that needs replaced regularly. He is the owner of the website solarpoweredideas.com

Can Solar Energy be Practical for every day Living?

October 31st, 2008

Recently, a friend bought $45.00 worth of batteries for use in flashlights. It occurred to me that they were spending quite a bit of money to keep flashlights in fresh batteries for basically emergency use. My mind kept asking me, was it worth it? Especially since the next a flashlight was needed, the batteries were dead. Since then they have started stocking up on flashlights that do not need batteries. Shake flashlights, ones that use a little magnet and store a charge crank flashlights, a flashlight that uses crank power to create a charge that will last up to 20 minutes. It occurred to me that it was actually cheaper to buy a flashlight of that type rather than a conventional one that needed batteries. They would not need to buy batteries again. They would always have a flashlight at their disposal that would actually work when I needed it. They would never have to worry if my flashlight would work in an emergency situation. Not only are there flashlights using such technology, but camping lights used this type of technology as well. Some use solar and crank type system to ensure continuous light. It is amazing to think that our technology has taken us so far.

Could it be that such technology was being used for other fundamental products? It was worth some research. To my surprise, we have solar powered watches that will operate for months off a single full charge. It is not necessary for them to be in full sunlight to be charging, artificial light will work also. We have radios that will charge using solar or crank power. Again, why buy batteries? Solar cells can be used to charge radios, cell phones, outdoor weather stations, radar detectors, even a car battery when necessary. Solar cell packs are now powerful enough to use as a charging unit for camping sites. Solar power is being used as a source of electric power to maintain a home environment. Solar cells are now made in to roll up or fold up for easy transportation. Solar cells are now being used on back packs. They are charging while a person is carrying items from place to place. How convenient it is to have our very own portable power Station to go.

Solar lighting fixtures have become very popular. It is so much easier to install solar lighting fixtures as opposed to conventional lighting fixtures. With conventional lighting fixtures, wiring must be installed from an electric source, usually the main electrical box, to the electrical fixture. An electrician is then needed to install the unit. On the other hand, a solar unit only needs to be installed on a pole or stake. In the case of a security light, the installation maybe on the side of a building, or a wall. As long as the solar cell is facing the sun and is not in the shade, the light will work fine. The setup time is minimal and the need to call in a professional to install the light is usually not necessary. Solar cells have proven to be reliable, lasting as long as 20 years.

Solar energy is now being used to heat hot water for homes. It is working so well, that some countries, such as Japan encourages all new buildings to have this system included in the design. Heating domestic hot water has becoming popular in California and Florida as well. Solar hot water is also being used as an alternative source of heat for homes cutting, down on the amount of fossil fuels needed to heat the home. Solar hot air panels are also in use as an alternative system for home heating. The units are installed in the south facing wall of a home. They are larger than a conventional window and usually incorporate a fan run off of solar energy. As the unit reaches a certain temperature, the fan circulates air from inside the home through the unit, heating the air as it passes through. It is then circulated back into the house. So the answer to my question is yes. Technology is being used for other products successfully. We have indeed begun to use alternative sources of energy in our daily lives. As we do so, we will be helping our environment. We are saving on fossil fuels and are cutting our living expenses as well.
