When politicians start talking about renewable energy, you know we have problems. Solar energy is a significant renewable energy and here is an overview of how the technology has developed.
Historical Advances in Producing Electricity From the Sun
Solar electricity is simply energy produced by harnessing the sun. It comes in many forms including electricity production through panels, home heating through passive systems and mobile packets for powering devices like laptops and RVs to mention only a few platforms.
Historically, sunlight has been used by mankind to produce heat ever since we first built structures. Without electricity, mankind soon learned to orient structures to capture the heat of the sun during the day and store it in ceramic or mud materials much like a blacktop parking lot will radiate heat after the sun has gone down. Early Greek structures show a particular use of this solar strategy as do Egyptian structures.
The production of electricity using sunlight is a much more recent phenomena. In 1901, Nicolas Tesla was the first person to receive a patent related to solar electricity, but he called it radiant heating. He sought a patent for a machine to capture the radiant heat, but nothing much came of the invention.
In 1904, some unknown physicist named Albert Einstein published a paper on the potential electricity production from sunlight. In 1913, William Coblentz received the first patent for a solar cell, but he could never make it work. In 1916, Robert Millikan was the first to produce electricity with the cell. For the next forty years or so, nobody made much progress because the cells were highly inefficient at converting sunlight to energy.
In the 1950s, Bell Labs got involved with NASA. Bell was charged with coming up with a solar platform to power spacecraft once they were in orbit. The solar industry would never be the same.
Gerald L. Pearson, Daryl M. Chapin, and Calvin S. Fuller started researching different areas related to solar, but not active parts of the NASA project. By luck, they meet and exchanged ideas. While their individual projects were failures, their combined efforts produce a much more efficient cell using crystallized silicon to convert sunlight into electricity. The efficiency rate of the cells was roughly 6 percent, a marked improvement over previous technology. In 1958, NASA launched the Vanguard Spacecraft, which was powered by solar panels.

In the following years, solar technology grew in leaps and bounds. Solar panels today are roughly 15 percent efficient, but also much smaller than they use to be. More importantly, companies are abandoning the panel platform and coming out with amazing new products. The first are shingles that look exactly like regular roof shingles and perform as such. Nanotechnology is also offering amazing possibilities with quantum dots, which are essentially solar panels on the quantum level. Eventually, these dots will be incorporated in things such as paint. Yes, the paint on the walls of buildings and homes will eventually also produce all the electricity needed for the structures.
Man has used the power of the sun for heat for a very long time. Only now, however, are we starting to master the technology to turn it into large amounts of free electricity.
Sea Turtles In North Cyprus
These fascinating creatures come ashore on the deserted beaches of North Cyprus between May and August to nest and Alagadi Beach is classified as a special protected area.
While on your trip in Northern Cyprus, you may be intrigued to know that this is home to some of the most significant turtle housing beaches in the Mediterranean. The two species that live and nest in Northern Cyprus are endangered species. Just about 10% of the loggerhead and 30% of the green turtles in the Mediterranean nest in Northern Cyprus. Bearing in mind that as little as 300-400 green and 2000 loggerhead turtles are likely to live each year in the complete Mediterranean, it is critical that people do all they can to help and protect these near endangered species.
These North Cyprus Marine turtles start their lives on land, where they come out to emerge from eggs, just after 45-60 days of incubation on land and in the sand. When these turtles hatch and emerge they then begin to make the attempt to reach the sea, they swim anxiously out to sea waters where they stay put for the remaining years of their lives, the only break in this would be when a adult female will come to shore and lay her eggs.
It is projected that only one single hatchling out from two thousand will make it and survive to full adult life and maturity. As soon as they are 25-30 years old, and reach 1-2 meters in length, the adult females and males with set out and migrate to waters off nesting beaches to eat and reproduce. For the duration of a nesting season a female lays 3-4 nests, each carrying just about 100 eggs. she will nest every 1-3 years and will always return to the exact same beaches. There is no exact number on how long these marine turtles live but they have been suggested to live up to 160 years old.
They are two species of marine turtles that find themselves nesting in the North Cyprus Mediterranean and they would be the loggerhead, caretta caretta and the green turtle (chelonia mydas) the grand total number of both of these turtles has said to be a estimated 300-400 for the green and 2000 for the logghead females that nest each and every single year. Both of these species of sea turtles are endangered , more so with the green turtles. It has said to be that North Cyprus and Turkey seem to be the only nesting grounds these turtles come to love. There is over 80 beaches along North Cyprus that between may and October and monitored closely for the precious turtle activity.
While on your stay in North Cyprus and wish to see these lovely creatures you may indulge in a boating experience of the shore and see these turtles swimming, and with many places to see at night you might catch a glimpse of these night nesting turtles.
Group of Ecologists and students have been observing and helping to protect these rare animals from extinction for a number of years.
