I am studying in 5 course, writing a diploma on the subject of plasma waste recycling. We sit with the manager, we are dealing with the technological scheme of the installation, on which we have been working for several months. He explains the principle of its action in detail, drawings. Suddenly, he abruptly silences and unwaveringly gives out: "And in general, this installation makes no sense. It cannot work in principle. But only you and I will know about it..." o_o
