[SOC] Achievement Awards

I was just wondering if SOC has ever offered achievement awards for technical excellence. If so, then I feel compelled to add myself to the list and share a method for testing for "Power Mains Noise" that I created. 
We all know that we can hear atmospheric and man-made noise in our receivers, but how many of us really know how much powerline noise is getting into our transmitters. So, I put my engineering hat on and came  up with a method.
1. Get an 8 Ohm loudspeaker2. Wire it with a male 2-prong AC plug3. Plug it into the 120 VAC wall outlet hat feeds your transciever.
I've tried this and was amazed how much noise I heard. The test didn't last long, maybe 3 or 4 milliseconds (maybe one of the components was faulty).
Hint; use a very, very large loudspeaker, since this test will draw in excess of 'legal limit', actually about 1.8KW. (8 Ohms at 120VAC = 15 Amps...you do the math).
Anyhow, I don't expect anything too fancy for this achievement award. Maybe a simple walnut plaque with engraved bronze plate or a certificate (printed on parchment) and suitable for framing.
I hope there will be other applicants for this award, because I'd feel guilty with a slam-dunk victory.

Thanks in advance to the Awards Committee. I originally sent this message on April 1st, but it bounced back for being 'exceptionally ludicrous' ... whatever that means.
Let me add that some mental "experts" are claiming that all this CV19 self-isolation (quarantine) can cause delusions, non-linear thought processes, confusion and brain fog. I don't necessarily agree. Anyhow, try to remain sane during the pandemic thing. Don't touch anything, don't talk to anyone, don't go anywhere...wash your hands at the top and bottom of the hour and for goodness sake wear a mask, gloves, ear plugs and safety goggles.
