How do I do the tests to check people?

If on an android phone:
-Go to the about phone section in settings. In there will be something that says "build number"
-Tap on this about 10 times
-Developer options have now been enabled (basically just more settings)
-Now search in your settings for "Show bluetooth addresses without names"
-Enable this setting
-do a Bluetooth scan in a public area with people who are likely jabbed

Now you'll be able to see these MAC addresses. Some could be cars or other devices but that is rare.
To confirm, if you google Mac address vendor search you can input some of these addresses and you will get no result - no branding like Samsung or whatever will appear.

Really though the sheer number of them should let you know that you are seeing not just devices

As for the power. Its either energy sapped from the body in some shape or form or absorbed from the EMF soup almost all of us are in most of the time. The clots have nanowires in them, it's not to far from an antenna.
The antenna could take that AC energy from the air and rectify it into usable DC energy.
Or could be both. Until we get a guinea pig vaxxie, EMP the address away and put him in a faraday cage to see how long it will take for the address to come back, vs a control EMP vaxxie with no faraday cage, we won't know.
