How to generate electricity at household level without major infrastructure in buildings and homes using wind power.

Among all types of renewable energy sources as wind is the most secure, affordable and accessible since it does not waste, air emissions or share other resources such as land use to grow plants or flowers. The new designs allow innovative wind energy projects at home or even made a smaller scale and size.

Advantages of wind energy

Its cost is competitive and payable in relation to other forms of production and according to data from Spanish Electricity Network customer pays per kWh (kilowatt) an amount of 6.20 cents with a difference of 3.15 cents more than in others. Using computer models, new innovative technologies, elements inspired by others, or different biomaterials biological principles can study nature through science called biomimicry. Through these model systems (mechanical) and processes (chemical) can mimic the aerodynamic shapes of nature coming to the wind.


Wind Turbines silent: biomimicry

The kinetic energy of moving air provides mechanical energy through a propeller that rotates the rotor to a generator (alternator phase) to convert it into electrical energy through the science called biomimicry . These turbines can operate in isolation or grouped in wind farms based on other factors such as turbulence or the environmental impact they generate. Similarly there are those who are silent as the design of the company Whalepower a wind generator that captures the same shape of a fin or humpback whale silent wind turbine model QR-5 company quietrevolution in their vertical axes S-shaped cushion can reduce noise and vibration and can generate annually between 5000 and 10000 kWh.

Wind turbines high-tech

When a wind exchange with the movement of the rotor shaft with the wind turbine produces electricity. They can be horizontal as windmills or generators multipalas or vertically as the model Savonius created by the Finnish engineer Sigurd J. Savonius in 1922 and the model Darrieus patented by French engineer Georges Darrieus in 1931. There are wind turbines almost invisible in their reflections only detected their movement as the turbine is designed by Philippe Starck for Italian company Pramac. Made of lightweight material accumulator that connects even transforms their movement into electrical energy. Can be installed on the roof and may cover between 10 to 60% of the user’s needs. No blade and is sold in an amount ranging between 300 and 400 euros.

Portable wind generators and turbines with aeroelastic flutter

In countries around the world with light winds it has developed over the years a type of wind turbine designed for installation on roofs and balconies of houses coupled together through a system of toothed plastic wheels that turn with the wind. The accumulated energy is stored in a small battery, easy to transport and economic relations with prices ranging at $ 25. Similarly developments in design and technology come into buildings through the installation of different wind turbines mounted or within such as American building called Eco-Shell of Michael Jantzen made ​​from recycled steel and designed for agricultural land. Dome-shaped covers 100 m in length and consists of 9 chambers in which light enters through windows.

You can also generate electricity by harnessing vibrations generated by the wind based on a system called aeroelastic flutter with which turbines of various sizes similar to those of mobile phones which capture the wind and convert it into electricity as the American system developed by Shawn Frayne Windbelt. One of the purposes of the Department of Energy and the AWEA and American Wind Energy Association is that 20% of U.S. electricity comes from wind power with the help of 10 wind turbine models and previously created.
