Applications of the Magnus Effect

This phenomena has been researched extensively, it has proven very useful and applicable in many seprate fields:

Flying machines: 

The Magnus Spherical Airship

Magnus Spherical Airship

This space age flying machine was actually built as a prototype in 1982 and was called the Magnus Spherical Airship.  This lighter than air flying machine generated execss lift by rotating its giant sphere at the connection points at the sides of the machine. The lift generated by the rotating sphere could be utilized to haul cargo and people.


The MARS alpha prototype

This flying electrical generator is called the Magenn Air Rotor System (MARS). The drum shaped body of the machine rotates with wind, this spins generators at the connection points producing electricity. 
"Helium (an inert non-reactive lighter than air gas) sustains the Air Rotor which ascends to an altitude for best winds and its rotation also causes the Magnus effect. This provides additional lift, keeps the device stabilized, keeps it positioned within a very controlled and restricted location, and causes it to pull up overhead rather than drift downwind on its tether." (Magenn)

Ballistics of Paintball:


Advanced long range paintball barrels eject the paintball with backspin.  Much like throwing a slider in baseball the backspin of the paintball creates a Magnus effect that keeps the ball flying straight over a longer distance.  The Magnus effect is proportional to the velocity of the of the projectile so eventually when the paintball slows it looses its Magnus effect and falls to the ground.
These modern barrels can double the range of a paintball projectile.
