Electricity in the pocket or to receive energy from water and air
The strength of the water flow to generate electricity and to faithfully serve mankind for more than 100 years. But that the former may come to mind to users FORUMHOUSE when it comes to hydropower? Usually conjure cyclopean construction of hydroelectric blocking the river. Now imagine a small water wheel made of advanced composite materials, which forces two people can be set in a water flow and power which will be enough to power the refrigerator, TV and a laptop. It sounds like science fiction, is not it? But the Japanese engineers from the company Ibasei I do not think so, announcing last year its latest development - a miniature water turbine called Cappa.
The turbine requires no excavation and can be installed in a water flow on spacers. A at a flow rate of 2.0 m / s, this system can produce 250 watts of power.
According to representatives of the company - based turbine uses a special form of the diffuser, so that even a small water flow is accelerated and rotates the blades of a turbine, producing electricity.
The generated energy is converted into electricity by a generator. Then, by the controller, the direct current is converted to alternating frequency of 50/60 Hz, which can be used at home.
In that section our forum, you can learn all the features of the use of inverters.
They hope the engineers at a cost of about $ 10,000 this turbine will be an indispensable assistant for private homes. If necessary, it is possible to install multiple such turbines in succession, which will substantially increase the production of electric current. The main thing only, to near your home a river.
wind Catcher
But what if there is no river? Seek help from a wind catcher or as it is often called Wind turbinesBut not to the simple.
All of us used to the wind turbine generates electricity using the rotation of the blades. And, despite the fact that wind energy is spread almost everywhere, it is often not enough to generate electricity necessary power. The reason is simple - the efficiency of blade installation has almost reached the ceiling. But modern technology does not stand still, and one of the latest developments of the company of hot Tunisia, Saphon Energy, wind turbine became Saphonian. Rejecting the blades, wind turbine engineers have developed more like a satellite dish. So what is the principle of operation of this device?
Interchanging turbine on the sail which has a high coefficient of aerodynamic resistance, engineers achieved that a sail in the wind stream oscillates and capturing twice the kinetic energy transfers its movement via piston system - a hydraulic system which, by rotating the generator shaft, converts energy into electricity.
Through this approach, says the company achieved almost noiseless installation, degree current generation as compared with similar sized plants grows 2.5 times, and the value of wind turbine Saphonian almost half.
About the self-construction of plants for alternative home power sources discussed in detail in this article .
As shown by preliminary tests wind turbine with a diameter of 120 cm sails, generates electric power from 400 to 600 watts. And at the moment, the company's engineers are working to improve plant design.
Thus, using modern technology choice of alternative energy source significantly expanded, allowing to give your home-town greater autonomy and independence from energy suppliers.
