The wind has always been a symbol of impermanence, and attempts to transform its energy into electrical energy has led often to results that are not very encouraging. Indeed, everything you expect from the source of electrical energy stability: clicked the switch and turned on the light. And the wind, alas, changeable. However, to make it a reliable source of electricity possible, to use already well developed scheme with intermediate energy storage battery.
Everyone who decided to deal with bees, one has to prepare oneself to much. Including to what happen alone, “remove” ROI. The point is, I know for myself, is not simple. After all, bees are “grafted” (sit down when swarming) often where a person (without appropriate training, equipment) and get something easy.

At the teen club Amateur designers “Original”, which Sergey Dmitrievich runs on a voluntary basis, already built about a dozen unusual machines: from moped to hydrometallation. The purpose of all machines the same: to serve children’s interests. So the young craftsmen design themselves, build themselves, themselves and ride. It all started with aquapad “Dolphin”, which S. D. Rudenko came up to summer at the lake the boys had fun.
RC model airplane, provided in this publication, it is highly unusual for the national school of design. First of all it is established in accordance with more and more of the fashion for Maxi models (it is appropriate to recall that the rules of competitions of the International Federation of air sports is not the first year there is a subclass supermystery models).
