A Brief History of Solar Power Solutions Through The Ages Business Articles | August 9 Joe Carter Indians Jersey , 2010 Solar power solutions have been used by various civilizations all over the world since ancient times. These systems have been used to heat dwellings, heat water and recently solar power has been used to generate electricity as well. Understanding where these various solutions began and how they have changed over the years is vital to the continued improvement of this technology.
The use of the sun as a power source dates back to ancient times and has been used by cultures all over the world ever since. The history of solar power begins when the earliest use of solar power was to warm dwellings by building them into the side of hills where the sun could warm them during the day. This heat would then be released all evening to keep the dwellings warm. This form of passive solar heating is still in use today with minor improvements through the years as it has been adapted for modern residential homes. The Romans were so serious about the harnessing and use of solar power that they constructed large buildings with southern facing windows to capture the heat from the sun. The water used in their bathhouses was also heated by the sun and they designed elaborate collectors to capture this heat to warm the water with solar power. These early societies even passed laws guaranteeing certain solar rights to ensure a homes clear access to this essential solar resource.
Solar Technology goes Commercial
These crude collection schemes were later refined in the mid 1700's by a Swiss inventor named Horace de Saussure who invented the first commercial solar collector. He called it a hotbox and it was used to cook food using nothing but sunlight for fuel. Many of the techniques pioneered as part of this invention are still being used today in modern solar water heating systems. In fact the first commercial solar water heater was produced in 1891 by an inventor named Clarence Kemp that was based on some of the same principles used in this original hotbox.
Solar Goes Electric
This brief history of solar power continues with the discovery of the photovoltaic effect in 1839 by Edmond Becquerel. He noticed that certain materials will produce a small electrical current when exposed to sunlight. This single discovery gave birth to the modern PV technology used in home solar power systems available today. Even though this initial discovery was little more than a scientific exhibition, the concepts he discovered have been improved and refined throughout solar power history to allow these PV home solar power systems to provide a good deal of free power from sunlight.
The Introduction of Silicon Materials
This chapter in solar power history got another significant boost when an American inventor named Charles Fritts made the first solar cells out of silicon wafers instead of selenium in 1883. This single discovery in solar power history made these home solar power systems more efficient and affordable than ever. This was also a historic event in the history of solar power because the older solar cells made of selenium were not safe for commercial production with the manufacturing techniques available at the time.
Growing Silicon Crystals
The development of the silicon crystal line of solar cells continued until a Polish scientist named Jan Czochralski developed a technique in 1918 for growing single crystal silicon. This is far superior to older types of silicon and is several times more efficient than anything that had been available up until this point. This one single event made solar power for homes a reality by allowing modern solar panels to generate a large amount of power from simple sunlight. Modern solar cells are created in much the same way today and through the addition of other doping agents have increased their efficiency several time that of these earlier models.
Words like 'neighbourhood' and 'community' have lost their meaning over time. The joys of living in a neighbourhood where people care for each other and live like one big family cannot be explained in words. The worst part is the fact that such families do not exist anymore. We can either recall them in our faint memories or read about them in books. What else can you expect from life in the fast lane, where people are too busy participating in the race called life? However, I feel if we make an approach we can create the very same helpful and caring neighbourhood for ourselves Corey Kluber Authentic Jersey , as well as for everyone around all over again. Here are a few tips which would help you all stay motivated.
Arrange weekly get-togethers
I agree to take out time for community or neighbourhood get-together can be quite difficult, but taking out a couple of hours each weekend doesn't sound too much. I know we all have plans for weekends to go out and have fun, but if we try we can definitely carve out some time from our tight schedules. It's all a matter of choice. You may feel a bit odd the first few times Jason Kipnis Authentic Jersey , but as you keep meeting each other week after week, you too will start liking it. Once you develop a liking for these meetings, you too will feel like contributing to the welfare of your neighbourhood.
