Very relevant in our day is the issue ofdevelopment of alternative methods for obtaining energy. The main problem is the depletion of traditional sources, the reserves of which can last no more than half a century. In connection with this, the cost of energy resources is already quite high. This has a significant impact on the economy of many countries in the world.
To eliminate this problem, the inhabitants of our planetThey are constantly looking for new ways of obtaining energy. To solve this issue, various methods are being developed. The most important of these is the energy of the Sun. The person enjoys the gifts of the heavenly light for a long time. The sun's rays give life, light and warmth. The energy of our star controls the wind and rivers. Even a simple bonfire is a gift from the heavenly body, accumulated in wood. If we theoretically calculate the amount of conventional fuel delivered to the Earth by the sun's rays in a calendar year, this value will be equal to almost one hundred and trillion tons. The volume of this energy exceeds the needs of mankind tenfold.
As a result of many years of work, scientists succeeded increate an innovative device. They are a solar battery. A special device, whose efficiency was as high as six percent, was released in 1959. It was created by American scientists. Already four years later the solar battery was the main source, which allowed to receive electricity on aircraft in outer space. And in the future, scientists were looking for ways to improve these devices.
The solar battery, created in the seventieslast century, had an efficiency factor of ten percent. This was enough to use the device in space vehicles. To work in terrestrial conditions, the device was inefficient. At present, the solar cell is capable of converting energy with an efficiency equal to thirty percent.
An alternative method of obtaining fuel isunquestionable advantages. Solar batteries are simple and reliable in operation and do not require additional resources. In addition, the devices are not subject to mechanical wear and do not need maintenance. Solar panels are durable. Devices are able to convert energy rays, serve for at least twenty-five years. In addition, these batteries do not emit harmful substances into the environment, which indicates their compliance with the most stringent environmental regulations. Do not forget about the possibility of saving a significant financial amount when using these devices. It is released when the cost of traditional fuel is reduced.
Modern scientific developments have enabledrelease of the "eternal power source." They are a portable solar battery. This device can be purchased in the retail network. It is purchased for charging navigators, cell phones, digital cameras, etc. It can also be used for laptop and netbook batteries. A solar charger with small dimensions gives less current. If the device is small in size, then it can only be used to recharge a cell phone. The laptop can not charge it. More powerful solar panels ensure the battery life of a laptop computer for several hours.
