Personal non-property and property rights for the invention belong to the author and protected under current legislation. 
 The idea is that when you open establishments (cafes, stores, etc.) using pressure from the compressor pumped air into the façade elements. The facade, signage, the name of the institution and even the visor to be first, big and beautiful, it can increase and decrease, and secondly, at night it will be "hidden" that describes him as a vandal-proof design. Elements of the facade is always possible to add or remove. Of course, all this is combined with light elements. Also, for example, while opening any institution, the entrance is decorated with balloons in the form of colorful compositions. In the case of inflatable facades, publisher, system requirements;-elegant entrance will welcome visitors always.
The idea is open to investing in the partnership.

The device is based on the principle of absorption and heat during deformation of the metal.
A group of German researchers at Saarland University (Saarland University) has created an unusual heating-cooling system, which, when used in refrigeration, can at least be three times more efficient than modern similar devices, not to mention its other advantages, reports Chronicle.info with referring to Esoreiter.
If we speak in a somewhat simplified language, then the essence of this refrigeration generator lies in a rotating cylinder, on which the nitinol wire is wound, which stretches in one direction of rotation, and in another is compressed. Nitinol (a unique alloy) is capable of absorbing heat when it is expanded, and when it returns to its original position, it can give off. Experiments have shown that the temperature difference in this case can reach, even at the minimum value, 20 degrees.
This is what one of the co-authors of this invention, Professor Stefan Seeleke, says about this:
We were able to calculate the diameter and size of the nitinol wire, the speed of the drum, the parameters of the air flow from the fan and so on, as a result of which we achieved not only an impressive temperature difference of 20 degrees Celsius, but also the system power 30 times greater than the effort required by the operation of this installation.
It is three times more efficient than a modern refrigerator. But in principle, in the future when creating industrial units of this type, the indicators can be improved several times. Moreover, this refrigerator does not consume toxic substances (environmentally friendly), does not require hermetic pipes, heat exchangers and other intermediate links.

There is only one very important question: if the nitinol wire will constantly expand and shrink again, how much is enough? But it turns out that this alloy differs from many others in its fantastic fatigue resistance, which makes nitinol, for example, used in arterial stents, which allows such an implant to shrink, curl, stretch and so on along with the blood vessel for an infinitely long time. In addition, this metal is relatively cheap, which, together with countless expansion-compression cycles, makes it optimal for the cooling system in question.
