The scientists see a way to solve the problem of providing the population cheap fuel in the production of bioethanol. In our country, a lot of non-irrigated land and unused. If there is to grow Jerusalem artichoke, that is, Jerusalem artichoke and produce ethanol, it can be part of the need to provide fuel at the expense of its own resources. In some factories, due to a minor facelift, you can set up production of bioethanol. This is a very profitable business. The Academy of Sciences in cooperation with the Ministry of Energy and Industry, local executive authorities must find new alternative energy sources, to give scientific advice to their widespread introduction in the production and life of people.

        The optimal ratio of passive and active heat sources for heating the “Solar House” model has been experimentally determined. It is shown that the “Solar House” is heated by solar radiation with an average power of about 2 kW, as well as by heat flows through the walls, roof, floor - 1 kW. Heat losses, solar radiation fluxes through windows and heat fluxes through fences (walls, roof, floor, doors and windows) are calculated depending on the time of year.

        The management of the Solar House energy supply system was automated based on a remote control scheme that allows switching 4 lines of lighting on and off at a distance of up to 25 meters from a mobile console with a timer.

      On the basis of a solar battery (100 W), a battery (with a capacity of 40 A.h), purchased in the PRC and a charge controller of its own development scheme, a solar power station is assembled, which reliably ensures the operation of a portable TFTLEO color TV with a DVD player and radio, as well as several energy-saving LED lamps.

         Designed, manufactured and tested a charge-discharge controller with battery pack. In the period January-June 2014, three modifications of the charge controller and two types, an open and closed battery pack, were tested. The controller provides a charge-off mode when the battery voltage reaches 14.5 V and when the voltage drops below 10 V it shuts off the load.

         The dynamics of the growth of the biological mass of Jerusalem artichoke, the formation of leaf surface and the mass of tubers during the growing season were studied. It has been established that cultivation of Jerusalem artichoke in one place leads to a 20% decrease in its total biomass and yield, in contrast to planting plants in a new place. A new form of Jerusalem artichoke with a smooth surface of tubers, conventionally called "Universal", was obtained and multiplied.
