Everyday, Solar energy and Wind Energy become more necessary to keep our environment clean, so researches all around the world are being done all around the clock.
Some inventions had been already established, other are still just researches.
We already have three generations of solar cells
The first generation solar cells were large, silicon-based are common used in the market. The second generation cells are cheaper than the first generation but have lower efficiencies. The third generation solar cells contains a wide range of potential solar innovations including polymer solar cells, nanocrystalline cells, and dye-sensitized solar cells.
Solar Power Generators
Solar power is the conversion of solar energy into a useful form of energy.
The solar thermal power industry is growing rapidly. There are several Solar Stations in the world especially in USA, Spain. In developing countries, Egypt, Mexico, and Morocco, the World Bank projects for integrated solar thermal/combined-cycle gas-turbine power plants in have been approved.
Wind Power Generators
Wind power is the conversion of wind energy into a useful form of energy.
Such as using wind turbines to make electricity, wind mills for mechanical power, wind pumps for pumping water or drainage, or sails to propel ships.
Several countries have achieved relatively high levels of wind power penetration such Denmark, Portugal, Spain, Republic of Ireland, Germany and other 80 countries around the world are using wind power on a commercial basis.
There are two kinds of wind power farms onshore and offshore. The onshore wind farms take advantage of the strong winds flying over the ocean, so the offshore are more effective than land wind farms.
The previous inventions are already used but the following inventions are under construction.
Flodesign’s “jet engine”-shaped wind turbine
It is three to four times more efficient than the usual turbines. Flodesign’s wind turbine design is made more simple and small. Its blades can handle high wind velocities, and the density of the wind farm can be much higher. You only need one truck to carry all of its components to the building site.
Futuristic Tornado Tower Uses Wind Power
A Tornado Tower is one of the inventions that are bringing green tech to a whole new level with its rotating facade that produces power from high-altitude winds.
The following projects are still researches that are waiting to go.
Wind lens that triples the power of wind turbines
A group of researchers led by Kyushu University professor Yuji Ohya has recently unveiled its latest invention called Wind Lens, a structure that resembles a honeycomb. The structure is meant to increase the amount of wind energy generated by offshore turbines.
Spherical Generator that produces solar and wind power
Arttu-Matti Immonen is an industrial designer who came up with the idea of combining wind and solar energy in one device, thus considerably increasing energy output. He managed to design a generator called Aard.
