Solar energy – a source of life
Without Sun there is no life on earth
Solar energy – Sun, a center of the Solar System, one of the brightest stars in the Milky way, 109 times bigger than planet Earth, and it’s most important source of energy.
Without Sun there is no life on earth. Mankind has tackled this fact since the morning of time.
Sun driven technology
Nowadays we are solving this problem using modern technology.
Residents of northern hemisphere, tackle the lack of sunlight.
Depending on the location, during winter in northern Scandinavia, residents „enjoy“ 2-3 months of twilight.
In Hammerfest city, Norway, located on uttermost north, sun remains hidden for even 1500 hours.
There, people have developed a special kind of depression, one caused by sun deprivation.
Modern technologies have step up and reduced the problem by mimicking the nature, and developed a solution.
An anti-depressive lamp that imitates sunlight, that has a healing effect and uplifts the mood.
One can find that lamp in almost every Scandinavian home, due to the fact that lack of sun energy is so fatal.
Solar energy at it’s best
We finally, very cleverly, found a way to use solar energy to work for us every day.
Through solar panels, panels that convert solar energy into electricity.
Although the initial cost of installation and adjustment of panels is rather high, once installed they provide free energy that will pay start-up costs during the years of use.
Very convenient for areas with plenty of sunshine.
One specific city in the USA abounds both sunlight and energy; city of Scituate, Massachusetts.
Scituate is the first city in the world that is 100% powered using exclusively renewable energy sources.
Entire city facilities, including water supply, sewerage, City buildings and street lights are driven exclusively by solar and wind power, solar panels and windmills.
Concentrating solar power
Solar energy is used also for driving a big and demanding entities, such as power plants, by concentrating solar power.
Concentrating solar power is used to drive large generators or heating installations mostly in power plants.
Concentration is achieved by using many lenses or more often using mirrors arranged in a plate or the configuration of the tower.
“Power Tower” configuration is using computer controlled mirror’s field for focusing sun radiation to a central tower, which then drives the main generator.
“Dish” system monitors the movement of the Sun and thereby concentrate solar power.
These new systems have the ability to work through the night and in bad weather, so that storing hot liquid in very efficient container (a kind of thermos bottles).
