Very relevant today is the question of the development of alternative methods of energy production. The main problem is the depletion of traditional sources, the reserves of which can last no more than half a century. In this regard, at present, the cost of energy resources is already quite high. This has a significant impact on the economies of many countries around the world.
To eliminate this problem, the inhabitants of our planet are constantly looking for new ways to get energy. Various methods are being developed to address this issue. The highest priority of them is to obtain the energy of the Sun. Man has been using the gifts of the heavenly body for a long time. The sun's rays give life, light and warmth. The energy of our star governs the wind and the rivers. Even a simple fire is a gift from the heavenly body, accumulated in wood. If we theoretically calculate the amount of standard fuel that the sun's rays deliver to Earth forcalendar year, this value will be equal to almost one hundred trillion tons. The volume of this energy exceeds the needs of mankind ten times.
As a result of many years of work, scientists have managed to create an innovative device. They are solar panels. A special device, the efficiency of which reached six percent, was released in 1954. It was created by American scientists. Already four years later, the solar battery was the main source that made it possible to obtain 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 seventies of the last century, had an efficiency of ten percent. This was enough to use the device in spacecraft. For work in terrestrial conditions, the device was ineffective. Currently, the solar panel is capable of converting energy with an efficiency of thirty percent.
An alternative way to get fuel has undeniable 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 require maintenance. Solar panels are durable. The devices are capable of converting the energy of the rays, they serve for at least twenty-five years. Also, these batteries are notproduce emissions of harmful substances into the environment, which indicates their compliance with the most stringent environmental standards. Do not forget about the possibility of saving a significant financial amount when using these devices. It is released when the cost of conventional fuels is reduced.
Modern scientific developments have made it possible to launch the production of an "eternal source of food". It is a portable solar battery. This device can be purchased from a retail network. It is purchased to charge navigators, cell phones, digital cameras, etc. It can also be used for laptop and netbook batteries. A solar charger with a small size gives a smaller amount of current. If the device is small, then it can only be used to power a cell phone. It can't charge a laptop. More powerful solar panels keep your laptop battery running for several hours.
