content: 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!

content: Quote from: madires on July 17, 2021, 02:43:17 pmProbably 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.

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 PTSDhttps://www.hillandponton.com/part4-rating-ptsd/

content: 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.

content: 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?

content: 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.

content: Quote from: Cyberdragon on July 19, 2021, 08:29:34 pmSounds 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).
