Actually, my father was a consulting engineer who for 25 years helped companies get U.L. listings for their products. Some of his knowledge rubbed off on me.
U.L. requires "production-ready" devices to test. They don't have to be manufactured on the assembly line used for production, but they have to be build using the same materials and processes as the production version. For example, if the production version uses welded seams, the submitted device can not use bolted seams.
It's obvious (and has been for months) that Rossi has been lying about every business relationship he has mentioned. He's been starting talks with companies, then name-dropping this to his shills, and then terminating the negotiations before he had to spend any money or provide a working device.
He did this with the University of Bologna, the University of Uppsala, NASA, National Instruments and now Underwriter's Laboratory.
Note that his current victim is Siemens. I expect to hear the same story from them soon.
