Eegore, you need to be more familiar with the entire timeline. You are asking moldy questions that were posed a LONG TIME AGO and an entire University sponsored test series was done after that generation of machines came and went. Uppsala tests carefully handled the ground wire questions, so do your research on that.
Rossi now no longer does big public demos because of the time drain posed by questions like yours. He said he would eventually do a new series of public demos to showcase his newest tech, but then due to virus lockdown travel restrictions the potential business partners had to send people to Rossi instead so Rossi achieved his demos privately.
Yes, Rossi got his new tech's partner testing done privately and ROSSI FAILED TO IMPRESS HIS CUSTOMERS CONCERNING REACTOR LIFE AND DURABILITY ISSUES.
He still has interested parties following his EV charging technology which is intended as remote or mobile tech that has no ground wire involved in it.
==================================================
In looking I found some timelines for Rossi that go way way way back. The most exhaustive of which was put together by Steven B. Krivit, a very consistent and meticulous Rossi hater extraordinaire. Krivit's timeline includes a lot of
very tilted information from Krivit's own Rossi hating web pages.
Rossi tends to polarize people due to his manner, and he is so secretive it can cause even normal folks to instantly mistrust him.
http://newenergytimes.com/v2/sr/RossiECat/RossiTimeline.shtml is the Rossi hater time line.

Ian Bryce is an alternate skeptic that does not get along well with Krivit as they always argue as to how Rossi is cheating this time.
Ian Bryce also has a web page and has posted his own timeline which reads as a little less manic than some of Krivit's stuff.
https://skepticalinquirer.org/2019/05/rossis-e-cat-expose-of-a-claimed-cold-f...Ian Bryce is the one who came up with your hot ground wire powering everything hypothesis, so read here to see it all explained. Time line spot it as a pre-Industrial Heat issue thing, and then let it go as ground wire power was tested for in all post Industrial Heat tests that were done by various test groups.
The biggest remaining ground wire thing is that skeptic groups always seem to want the ground wire to be
constantly monitored in all tests, as they NEED that ground wire to be a hot power supply so very desperately or else they might have to actually believe that the E-Cat actually works.
Look boys,
no ground wire exists in the current E-Cat L tests, so get over it.
And yes, beamed microwaves has already been suggested (but nobody got their gonads toasted walking through the energetic beam path so you got to let that one go too).
