Wind lift

From The Great Ball Contraption Wiki

A great ball contraption wind lift uses a strong airflow that can entrain balls up a sloping ramp or even up a vertical shaft.

Two issues:

  1. making a powerful enough LEGO fan (or using a non-LEGO fan) to get the airstream
  2. making sure that the “lift column” never becomes so saturated with balls that it collapses. Possible mitigations are to use a clocker, or only lift a new ball when an old ball has fallen out.


A fan, impeller or compressor could be used to generate the airflow.
