A. Shpilman sells torsion generators for ~$230, I once considered buying one years ago to try the water/alcohol experiment, then I realized it was a waste of time and money.

That's not to say I don't believe something like torsion exists, it from bit as Wheeler described the universe still has relevance, my interests along these lines are more focused on the nature and properties of consciousness.
Jack Sarfatti is an interesting physicist/character who has had an interest in Shipov's version of torsion...as you already know, there are many versions.

For the sake of balance, Akimov was the fraud, Shipov was the theorist:
