Abstract There was proposed a compact underwater energy generating device in which energy is produced by underwater currents and tidal phenomena on the Arctic coast for small settlements. These communities will be created to track ships sailing along the Northern Sea Route and to provide operational assistance if necessary. The idea of the technical proposal is structurally distinctive, the device is carried out of a set of conventional pipes of a certain diameter with a fairly wide bell (funnel), horizontally mounted towards the underwater current. This idea is quietly new for Russia, and it’s learned not very well. Calculation was provided in a new way on the basis of Propellers theory. In result there are shown table with calculated efficiency of our turbines with defined quantity of turbines in machine unit. Also we suppose that our approach is more accurate then results obtained with Betz’s formula as so as Betz’s formula doesn’t consider geometrical option of impeller.
