Domestic wind power is one of the most interesting technologies, which is also why I have often spoken about it, "launching" projects Italian ed esteri which were little known to the general public (and now fortunately they are).
Given the current energy crisis, a renewable source of energy like wind can lighten your bills if it finds the right conditions to produce results.
Often, however, these turbines can sometimes generate less energy than expected: but that doesn't seem to be the case with this one, at least according to its inventor. Also because the dimensions are not exactly suitable for a small terrace.
Heliblue: take a turbine, you get two
The French engineer Christophe Martinez (I'll link his profile on LinkedIn) had the idea of developing Heliblue, a new type of wind turbine that is more efficient than what already exists on the market. His distinctive trait? It doesn't have three blades like most current turbines, but six.
Its dimensions are similar to those of conventional wind turbines: 11 meters high, 4.3 meters in diameter. The presence of the six blades provides the wind with a larger wind collection area, which is why its power is 60% higher than that of standard wind turbines.
The Martinez creation has another peculiarity: it exploits the variable pitch technology for regulation. This system is generally used to limit the rotation speed of large industrial wind turbines when they reach maximum power. Applied to Heliblue it makes these wind turbines quieter, more efficient and more precise.
How was a 6-blade variable pitch domestic wind power plant born?
Christophe Martinez says he invented Heliblue after seeing a neighbor install a home wind turbine. The characteristics of the device, the engineer recalls, were far from perfect. The wind turbine was really noisy, not very aesthetic and above all not very efficient.
For this, in July 2014 Martinez decided to research the subject and design a better quality wind turbine himself. Within a year, the engineer had finished the design and assembled a usable prototype.
The rest is recent history between authorizations, patents, first marketed models and even innovation awards directly from the French government.
Of course, as mentioned, I don't know how many people will have a solution like Heliblue at their disposal: the turbine is as tall as a three-story villa, and I imagine it needs space around it.
In any case, if you want more information there is always the official website. Good wind.
