Encoding many channels on the same frequency through radio vorticity

[Phil]

Well I'm no EE but I've never heard of EM wave possessing 'orbital angular momentum'. What's orbiting what now? On the other hand, it's a month early for April 1st. Apart from the reference to 'two incoherent radio waves" (Rush Limbaugh again?), this sounds like it comes from the team that brought you perpetual motion, the angular-to-linear-momentum drive, snake oil and cold fusion.

The demo shown in the original YOU TUBE video of what they did over in Italy was line of sight at 2+ Ghz and only about a mile delta between Tx and Rx antennas - i.e. there was no multi-path taking place in the video demo.  The practical application might be limited to fiber optic environments or it might work in a line-of-sight microwave tower to tower environment but, I doubt it will be of much good on 40m HF SSB. :-)
