People have long made the wind work for themselves. He lifted the sails of the first ships, twisted the wings of the mills, pumped water out of the ground. And now, in the age of electricity and atomic energy, the wind has remained our faithful assistant. A working large-scale model of a windmill can be built by every circle of young technicians. It will not be a toy, but a real technical structure. If desired, this model can be turned into an automatic meteorological station or forced to pump water for a small fountain or pool. Of course, such work is available only to more prepared circles.
