New music cases
“The words are blown with the wind…” Wind brings us the possibility of using it as an energy source. The wind turbines help us to do so, but exactly what they have in common with the new accordion cases ?
The energy comes from the wind
What is a wind turbine? It comes to my mind that they could also been called ‘wind users’ because they are modern mills where the energy of moving air (kinetic energy) turns into electricity to feed our daily lives.
The wind turbine is capable to seek its best position to get the most energy possible, thanks to the data provided by its vane (measures wind direction) and its anemometer (tells us the wind speed).
The mill operate with winds from 11km/h to 90km/h. Under higher speeds, the mill is in danger of diminishing its typical life expectancy that is 25 years, and therefore it is stopped and left in ‘flag’ position.
The key to everything is in the blades, which are the movable elements of the wind generators.
