Sun

Today

Solar energy is one of the greatest potentials for modern world. The necessity for reduction of fossil fuels,  its pollution causing production, increased awareness for environment, necessity for lowering electricity and heating costs is stimulating now-days brains into researches and inventions of better and better materials and technologies provided by solar energy. Every day we trace new articles about latest improvements concerning solar power. Until now we have been satisfying solar devices and technologies as: solar heating, solar power stations, solar lights, solar cars,..

Ancient glass

Yesterday

Far back in history solar power was used to form fire, by using concentrating sunlight through glass. Later on sunlight was used to ignite light for religious intention. Also buildings facing south were made to catch warmth from the sun during winter time and providing light and heat in bathing houses.

Futuristic Canuck

Tomorrow

There is an utopian idea about free solar energy in the future. It is a fact that solar technology and materials will improve a lot in the future and therefore also the possibility for people to use it without charge. Hopefully one day our planet will live green and content..

Scientists of Washington State University combined alternative energy of the sun  and the wind – solar wind power. This combination could provide enormous quantity of alternative energy that could satisfy human kind necessity for energy. The basic solar wind satelite  placed in the outer space would capture  electrons throug charged cooper wire. This future technology has great expectations in respect of  amount of enery that can provide, whic is 1 billion gigawatsof power, by using a massive 8,400 km wide solar sail to harvest the power in solar wind.

Nanotechnology is the study of manipulating matter on a very small scale. It includes atoms and molecules. Nanometer is so tiny, if we make comparison with the pin head, which has 1 milimeter (mm) in its witdth, than 1 mm is 1,000,000 nanometers (nm). That’s really tiny. But as many tiny things are bigger than we think, when combined into structure. Sometimes it can give us unimaginable source of power or endurance.
In last decade many best world’s known companies not only invest into researches of new materials, technologies based on nano scale, but already use it with high success. One of the examples is usage of nano materials for constructing efficient solar cells. Adding nanostructured inorganic semiconductors to organic polymers can produce efficient, flexible, and potentially inexpensive devices. In hybrid solar cells, inorganic-semiconductor nanomaterials get dispersed in an organic-polymer matrix. This approach provides lighwaigted, robust, lower cost and very efficient energy from the sun.

Using solar energy (or any other renewable form of energy) causes diminishing of harmful by-products of burning fossil fuels since we replaceit with renewable technologies.

By-products like carbon dioxide, nitrogen oxide, smog, particles from soot and dust are inducers of many health problems.

Carbon monoxide effects cardiac system and causes headaches.

Longer exposure to smog causes damage to lungs, asthma, aggravation of respiration.

Nitrogen oxide also weakens respiratory system, irritates lungs, sometimes defiance bronchitis and pneumonia.

Heart attacks, arrhythmia, respiratory and cardiac aliments are consequences of small particles from dust or soot.

Many people in highly polluted cities around the globe already feel the outcomes of polluted air. There’s a list of cities where industry with its eager for the money, sufficient energy supplies and car emissions in the city polluted the air over the maximum. All these effects health problems in a big scale. The list of 10 cities from 2008: Chernobyl (Ukraine), Sumkayit (Azerbaijan), Vapi (India), Tianying (China), Sukinda (India), Norilsk (Russia), Linfen (China), La Oroya (Peru), Kabwe (Zambia), Dzershinsk (Russia). With typing the name of one of the cities into your computer you will realize the heavy load the earth and people carry on its chests….time to rethink, time to react!
