	THE Venturi Column of production of electricity of nearness, by conjugated effects "Aeolian-photo-thermal ", who is in his phase of experiment, should resolve completely the problems connected to the use of photo-battery. The use of the solar energy to replace the pile of our remote control, can be a good initiative in the protection of our blue planet!

1-CompetenceS:

Aeolians are fames for the occasional production of electricity. However, without wind, it is necessary to wait for the vague return of the zephyr … This project, which the study is totally ended, has the advantage to use simultaneously the sun and the wind. Without wanting to reach big performances of production, he assures at least the production of electricity of nearness, for the isolated sites. The column can reach 27 m of height, and be painted and decorated according to the art which one wishes to give him.

It is unreasonable, on the other hand, to want to make of the heater with photovoltaic sun panels, because it would be needed disproportionate and unbearable installations financially.

2-Advantages:

Photovoltaic technology, is very different to thermal solar energy. I does not use the heat, but transform the energy of photons directly into electricity, thanks to sun cells, which are made with semi-conductor materials as the computer’s "chips". 

As the presence of the wind and the sun is often additional, the production of electricity of nearness by conjugated effects "Aeolian-photo-thermal" seems to have a prosperous future. This innovative concept allows to provoke a stream of air warmed by the sun brilliance, by conjugating this action with the suction provoked by the movement of the wind.

3-Benefits:

The custom photo-batteries for the production of electricity has an inconvenience. It authorizes with great difficulty the complete autonomy of a living house.

4-Realization:

An Aeolian helix, foreseen for the low speeds of stream, is placed in the two thirds of this column, at the level of an accelerating constriction. A drive-shaft passes on the movement in an allowing special alternator, about is the speed of rotation of the helix, to produce a 220 volt electric current, or 380 Volts, alternate current, of a frequency which varies From 48 to 52 Hertz, or Pulsations By Second, directly useful. By selling in batteries of stocking, the stored current could be directly used by low voltage devices, or reconverted by an alternating 220V current Converter. This concept has the advantage to establish, with regard to certain applications current Aeolian, a solution half forced comparable to the hydraulic systems, and obtain, consequently, a more steady production. As example, a machine of nominal diameter of 5m would reach a production an 25000 kW / hour a year, and a cost kWh, with amortizations over 10 years, of the order of 0.05 USD, on site averagely sunny and windy. Even if the Photovoltaic energy remains the most modern way to use the solar energy, to produce some electricity, It still suffers some defects bound to its constructive materials.
