On the mechanisms used to its movement due to inertia of the rotating imbalances of the journal “modelist-Konstruktor” wrote more than once (see number 5 and 12 for 1975, No. 6 1976, No. 3, 1978). The publication aroused great interest among readers, so we return to this topic. The amazing ability of nutricola, or inertsioidov, as they are called — to move without using wheels, tracks or air screw — continues to captivate enthusiasts-inventors. And although the effectiveness of this type of propulsion is not yet well-known competitor, perhaps one of the most perfect models of nutriton will be a prototype of the future transport. And while we offer to your attention another scheme inertsioidov mover. Its author — kas reader from the city of Ryazan Alexander Mikhailov.
