    Then that leaves out GW! ;)

    I think 'theory" can described as a 'concept of operation" or model from which predictions can be made and tested.

    Ok, I get it. Your post is pointing out the distinction between the vernacular "theory" and "science theory". Ya gots me. Of course, I didn't actually use the term "science theory" did I?

    I was making the distinction between proven and unproven science, or at least attempting to do so.

    I wonder how many scientists get up in the morning and talk about how the theoretical light from the sun appears to be warming their face. And there are things like science fact. Nobody talks about the theory of gravity. It's the law of gravity. Not all science concepts are theoretical.

    I recall that some years ago Lear (of Learjet) claimed to have found a new "spectrum", but don't think anything came of it.

    Claims are cheap.

    Actually

    JAXA announced on 12 March 2015 that they wirelessly beamed 1.8 kilowatts 50 meters to a small receiver by converting electricity to microwaves and then back to electricity. This is the standard plan for this type of power.

    On 12 March 2015 Mitsubishi Heavy Industries demonstrated transmission of 10 kilowatts (kW) of power to a receiver unit located at a distance of 500 meters (m) away.

    Granted, not 1000's of kM, but a starting point is a starting point.

    Franky, I doubt Space-based systems will be allowed as the also look very much like a weapons system. I even wrote lengthy a fiction story about that very issue set.

    The topic of the original post was wireless power transmission, and so I posted what I know to be both factual and proven.

    I can post photos if you have difficulty in looking this stuff up for yourself.... Like this

    Japan has a space industry, a quite one, that does a fair amount of basic research in space systems. Most in N/A are unaware that Japan has a heavy lift vehicle system that is both current and in use.

    Given the latest issues with nuke power on the island(s) - I can see why they are investing in basic research.

    What was their measured transmission efficiency? If they put in 1.8kW, how much did they get back out at the receiver?
    Well, no, you have a lot of claims. I'm not seeing any actual evidence of success.

    Didn't Nichola Tesla want to do the same thing about a century+ years ago?

    When I was married my wife could send power across the room with just one glance. I could feel the heat and get the message she was sending. I believe this is a well known phenomenon. My cat could do it also. Could these be Zennecks?
