Very relevant today is the question of the development of alternative methods of generating energy. 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 of the world.
To eliminate this problem, the inhabitants of our planet are constantly looking for new ways to obtain energy. To solve this issue, various techniques are being developed. The highest priority of these is to obtain the energy of the sun. Man has been using the gifts of the heavenly luminary 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 of the celestial luminary accumulated in wood. If we theoretically calculate the amount of fuel equivalent that the sun's rays deliver to the Earth for a calendar year, then 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. It is a solar battery. A special device, the efficiency of which reached six percent, was released in nineteen fifty-fourth. It was created by American scientists. Four years later, the solar battery was the main source, which made it possible to obtain electric power 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 a coefficient of efficiency equal to ten percent. This was enough to use the device in spacecraft. For working in terrestrial conditions, the device was ineffective. Currently, the solar battery is capable of converting energy with an efficiency equal to thirty percent.
An alternative method of producing fuel has undeniable advantages. Solar panels 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. Devices are able to convert the energy of the 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 standards. Do not forget about the possibility of saving a significant financial amount when using these devices. It is released while lowering the cost of traditional fuels.
Modern scientific developments have allowed the launch of the "eternal source of nutrition." It is a portable solar battery. This device can be purchased at the distribution network. It is purchased for charging navigators, cell phones, digital cameras, etc. You can use it for laptop and netbook batteries . A small solar charger gives less current. If the device is small, then it can only be used to power a cell phone. It cannot charge a laptop. More powerful solar panels provide portable battery life for several hours.
