Turbine

The turbine I made was designed to obtain a good air flow in a modest space and above all in safety. the motor I used is a 5V DC motor (dimensions: 12x20mm), with a rotation speed of 20000RPM. This guarantees a flow of air even at a distance of 50cm. The ventilation intakes for the fan must certainly be improved, as they are too small and (perhaps) also improve the shape of the turbine blades.
