"Truly unlimited number of keys"
What data type would you use to store such a key? My guess is that it wouldn't be much bigger than 2048 bits after being implemented. Besides, key length is a terrible metric for measuring security.

Whether this is any improvement on existing ciphers (which you can also design to have any size key you desire), is less clear, but I would bet on 'no'.
The fact they're not using the term "keystream" for this concept is a bit of a warning that they might've reinvented something every cipher algo already does, but more inefficient (from skimming through the paper).
Just guessing though. Not judging. I'm not a cryptographer, I just read about crypto as a hobby (and to know what I'm doing while using someone else's crypto primitives in my code).
