BTW, the 2.4 GHz ISM band is limited to 100 mW in most countries. Happy wireless charging!

[SiliconWizard]

Ahah, that's fun. The frickin project raised almost $5M too. What a bunch of idiots. We should definitely start projects on crowd funding platforms I guess. We are missing out on the cash cow?

Oh, "touchless, wireless power". It's not just wireless, it's touchless too! Don't f*cking touch meeeeeeee!

Probably some company in China makes it, and doesn't even bother to get it FCC certified. I wouldn't doubt that it actually uses more power than is legal for charging. I wouldn't assume its output was only 100mW. You can buy Chinese FM transmitters that output 10 WATTS of power, only legal if you have at least an LPFM (low power FM) license. By the way an LPFM license is something MOST people don't have, and can't get (you can only apply to the FCC for this license during an application window, and the last application window was like 10 years ago, and FCC seems to have no plans to open a new application window). So unless you already have a license for such an FM transmitter, who's output power goes WELL ABOVE the FCC Part 15 limit, it's illegal to use. Yet you can buy these ILLEGAL FM transmitters on Amazon, an American company, that should be following American laws.

So no, I don't doubt that this wireless charger operates at illegal power levels to charge effectively, because the fact is illegal stuff like that gets sold even on Amazon, the most trusted online store on all of the internet. And unless the FCC actually cracks down (and from what I've seen, they don't, unless they actually get a complaint from somebody about RF interference), people are probably going to keep making and selling illegal RF products, because only enforcement of the law is what will stop them from doing so.

According to them the transmitter power is 1W, using a standard RF amp.

No, it does not mean that.

In the US, the VA will use a percentage disability (and other factors) to determine compensation level https://www.va.gov/disability/compensation-rates/veteran-rates/

The determination of the percentage is complicated and depends on the disability. To give you an idea, here is some text on the determination of the percentage in the case of "Mental Disorders". edit: forgot to add a link e.g., for PTSD https://www.hillandponton.com/part4-rating-ptsd/

Ok, the inventor indeed fits 100% mental disorder diagnosis, given the invention.

Dave showed they were just using off-the-shelf dev kits for RF detection. The rest, IMHO, is of no interest. Trying to possibly figure out what they used as RF amplifiers - frankly who cares? It's rather clearly a pile of bullshit. Even their demos may not even be real. But if they are, they are clearly neither practical nor even legal. I thought it was fun seeing this plastic storage case used for the receiving side. They didn't even bother using a decent enclosure. It's a detail, but frankly, apart from the silliness of the approach, showing that you have so little means for prototyping your idea and still being able to raise $5M doesn't make any sense.

[Ultrawipf]

That one demo charging the iPhone does not even look like there is any wireless element present.
Did they just split the output from the amplifier into the harvesting boards directly? 

[MrMobodies]

When asked by a commenter to make the engineers understand better whilst being challenged by Dave they start talking about trade secrets/pulling down video's to blur bits out of it.

The video has already been seen what difference is it going to make now.

It just sound bullshit to me and it seems to getting sillier.

afaict they don't really want to make or develop anything, they just want to be a patent troll parasite that gets a cut any time someone uses wireless
power in case someone breaks the laws of physics and makes it work

Are they really? Morons! Bet they are gonna turn off ratings and comments now too. Hell, maybe they'd even try to copyright claim against Dave because that's what idiots on YT do.

DO they hold any patent? I didn't check.
But anyway, just getting several millions of $ is worth making a few fake videos and buying a few dev kits. Oftentimes those guys are serial startupers who just live off funding.

I think they might try the DMCA thing with their footage in the debunking video.

FIU - July 2021 WiGL Demo removed.
Check footage between 37:05 - 38:02 EEVblog 1408 - $5M WiGL Wireless Charging BUSTED!     


31,000 views it so doesn't matter whether they pulled it down to blur stuff out.
https://youtu.be/lDdRVtka0Jg?t=2223

In the other thread six second video containing "trade secrets" and this how daft that doctor is getting:

Just look at the VT video, it's 5 seconds of some professor pushing the cart. No opinion, no commentary, no other info.

LOL, the July 2021 demo at the university has been REMOVED!

That 5 second video of a guy wheeling a cart contained "trade secrets"!
The exact same hardware which can be seen in the live stread video in much closer detail and also with tech specs and a technical explanation from the WiGL guy.

The waffle doesn't stop with this guy 

LOL that that it contains trade secret stuff they haven't published yet.

I'll say it again I think Dave should give the doctor the bullshit of the year award.

Sounds like it is illegally powerful, just like I expected. At 1 watt of transmitter power, it should be possible to charge the phone quite rapidly in the near-field induction zone (and a bit slower in the far-field radio receiver zone).
