Outdoor gatherings often depend on a power source for music. With rising electricity costs and energy conservation concerns in mind, I suggest that you research wireless outdoor speakers that run on solar energy.
Wireless outdoor speakers adapt to CD, DVD, and MP3 players as well as TVs and stereos. Some even have accessories such as remote controls and AC/DC backup capability. They are portable, economical, durable, weatherproof, and your green friends will approve.
The first energy source ever used by man was solar energy. Of course the use was limited to Heating and drying things using direct sunlight. But it was used. Since early 1950’s solar energy has been a power source, but due to technological issues which marked it as an ineffective and expensive energy source. But with technology advancements, solar energy is moving up as a potential alternative to fossil fuels.
In 1953 Solar Power took a big step when Calvin Fuller, Gerald Pearson, and Daryl Chapin discovered the silicon solar cell. This solar cell could produce enough electricity and was efficient enough to run small electrical divices. The New York Times called this discovery “the beginning of a new era, leading eventually to the realization of harnessing the almost limitless energy of the sun for the uses of civilization.”(Picture is not of the first silicon solar cell)
Every one cares how their homes appear to others and your landscape plays a big part in how others view your home, solar landscape lights have become a popular and cost effective way to add a little light and beauty to your landscape efforts.
The history of photovoltaic energy (aka. solar cells) In 1876. William Grylls Adams along with a student of his, Richard Day, discovered that when selenium was exposed to light, it produced electricity. An electricity expert named Werner von Siemens, stated that the discovery was “scientifically of the most far-reaching importance.” These selenium cells were not that efficient, but it did prove that light could be converted into electricity without heat or moving parts.
In the last 15Yrs solar power has become a highly flexible power source Accent solar lights have become very popular for lighting gardens and paths.
Accent solar powered lighting: Their is a misunderstanding among many people that solar energy requires large, bulky solar panels. In truth, the solar industry has made major improvements in creating one piece solar systems. Solar lighting is one of the areas were going solar is easy and cheap. Read the rest of this entry »
