26ft torsional pendulum
50lb machine 50lb counterweight powered by two Harbor Freight angle grinders speed-controlled with dimmer switches. Harbor Freight "waterfall pump" for circulation. Wheels made from cheap aluminum cook pots. Valves made from swamp-cooler float valves. Anyone with a lathe should be able to build a version capable of flight. Enjoy.

Heres an experiment that you can try:
Take some fairly smooth, non-rotating airflow, maybe from an air-conditioner vent. Put a simple little rotary fan in front of it, not turned on. You should see the fan start to spin a little, driven by the wind. Now using some ribbons that blow in the wind measure the airflow behind the fan. You should see a bit of rotation, opposite to the fan rotation. Remove the fan and that rotation should go away.
This should establish for you that you can not convert angular into linear momentum. Should, but I suspect you will not understand the underlying mechanics involved.

What IS Angular Momentum?
It travels approximately 45ft in seven minutes.
