To know the present day usage of solar energy, we first must understand historical advances in producing electricity from the sun. When political figure start speaking about new and renewable energy, you know we have difficulties. Solar energy is a substantial renewable energy and here is a synopsis 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 phenomenon. 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. It could not become milestone for Historical Advances in Producing Electricity from the Sun.
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. This was the first major achievement which changed the Historical Advances in Producing Electricity from the Sun.
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. Today we are not looking back to see what has changed in Historical Advances in Producing Electricity from the Sun but are looking forward for the new inventions every day.
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.

Are Solar Powered Cars a Realistic Option?
Solar powered Cars could be the new wave of the future for a longer period or not.
True solar-powered Cars are literally electrical autos powered by solar panels. The panels would produce electricity by changing the solar’s rays into energy and saved into the batteries. These batteries would than power the electric cars or vehicles.
The downside is that makers of solar-powered Cars have not yet discovered or learned how to resolve some very huge issues…issues that hold true solar Cars from being commercially viable. However, with the emphasis by various Governments regarding push for Electrical Vehicles, the future seems to be promising.
In order to harness the energy of the solar successfully, solar-powered Cars would require to be extraordinarily light-weight plus they must be designed in order to be as near aerodynamically good as attainable…and neither of those limitations makes for a good highway car. After all, do not you need a automotive that may carry a minimum of 5 individuals and go 70 mph on the highway? And how about air-con?
If that is what you need from a car, you do not need a solar-powered Cars…not but. In the primary place true solar-powered Cars can presently carry not more than 2 individuals. Now, that is likely to be nice if what you need is a sports activities automotive. But, if you would like a sports activities automotive, you in all probability need it to go greater than a high pace of 60 miles per hour.
Granted, ongoing work on solar cells will enable them to change into a lot, a lot smaller and the Cars they’re used on to change into extra “user-friendly”.
But, within the meantime, simply because true solar-powered Cars may nonetheless be the stuff of goals, solar-powered hybrid Cars might truly turn into fairly sensible.
Indeed, programs that use solar energy to cost a hybrid car’s battery pack (together with a supplemental solar battery system) truly enable for hybrid Cars to function for prolonged duration within the electrical (relatively than fuel) mode earlier than needing to be charged. The use of such a solar power charging system might enhance gas financial system by a minimum of 25%.
By lowering dependence on recharging the hybrid’s battery by operating it on solar power, relatively than gasoline power, the use of solar energy makes hybrid autos much more “green” than they already are.
