An identity on Energy Science Forum as it was harvested, not an account on this site.
Nobody here has claimed it, and nothing connects it to a person by name.
I've also used the Gadgetman Groove on my 2000 WJ Jeep 4.7L V8 and had great results so far. I'm now seeing highway mileage when running around town, 12L/100kms (19.6MPG).
I've just grooved my '06 Prius too. No improvement initially, but I'm now seeing improvements. It takes some time to notice changes with the Prius, because of the hybrid drive, you can have wildly varying, short term results.
I'm Will from Australia. I just read your post, about having problems separating the oil from the air stream. A few years ago, I was asked by a local businessman, who turned out to be a conman, to assess some air conditioning technology. The company name is Earth to Air Systems (in TN) and they had designed a Deep Well Direct Exchange air conditioning system, that apparently approaches a COP of around 8 and I don't think that was using an inverter, just an old style, three phase, on/off compressor. One of the key innovations, was the ability to separate the oil from the refrigerant. I believe that it's a separately patented product. Randy Wiggs was the owner of the company and I suppose the patent. He was a real nice guy too.
I thought that there might be some synergy there, if you ever decided to rebuild your motor.
