Widespread in everyday life got electric pumps “Kama”, “Trickle” and others. They are quite efficient, reliable and unpretentious in operation, but are used as stationary units only where there is a nearby mains. However, if you replace the electric light internal combustion engine, the capability of the pump will significantly increase. Through the acquisition of autonomy it can be used to water a distant garden, to pump water from the flooded to the flooding of cellars, to wash the car.THE PUMP HOUSE IN D-6

Stories about the competition Experiment, systematically held in our country attract attention of not only athletes modelers, but readers are far from this sport.
