Okay… Where can I buy this product?

Notice that the company was started in 2013… And those “products” they have are literally impossible to purchase (I actually even signed up for “contact me!” to purchase one I’ll let you know if I get any information back… I’m willing to bet no.). This is sign 1 that this is bullshit. Notice that different materials show wildly different designs for products, none of which matches up to the actual product page. If something actually existed, it would look the same everytime we observed it… because you know… it’s real. Notice there’s no videos of the product actually working, just a produced video claiming it’s a live functions test… Except it’s a produced video. https://youtube.com/watch?v=HEfPgx51cas . The video claims that you can selectively stop charging things… That’s not how wireless antennas work at all. You can beamform to some extent, but if a device is near to another device that has an active beamformed lobe, you’re going to end up charging both(so they lied in the video). The video also uses a fuckton of terms RF terms really poorly. And they themselves admit it’s 1W of power. The shittiest of usb chargers charge at 12W (5v x 2.4amp). You will charge 1/12th the slowest charger, and isn’t actually even enough to trigger the “charging” notification in your notification bar. Further notice that the UI shows “zigbee ID” information. Zigbee is an already existing wireless mesh communications platform, typically used for IoT devices. The BEST zigbee controller chips already use 1/10th of your power budget. One of the major usages of Zigbee is controller lights and stuff… It’s much more likely that they built a “charging case” that is just an LED and battery that they can flip the light on and off to make this BS video.

It is vaporware when we’re talking about purchasable products… and you can’t/never could purchase it.

There’s been dozens of company’s claiming that this can be done. They’ve all failed. None of them have brought a viable product to market. Exactly the same story as hyperloop, where every company lied and failed to produce.

https://youtube.com/watch?v=lDdRVtka0Jg Other companies have even published ACTUAL attempts at “real world demonstrations”. Which have been proven to be bullshit. (starts at 17:40) I’m sure youtube will link you to the other dozens of these products that EEVBlog themselves have debunked by walking through the materials and calculations. If you can point to even ONE Thing that OSSIA is doing different than the other 10 companies doing the same damn thing (poorly) then I’ll eat every fucking work I’ve written. But it’s all bullshit, putting 500W into a sending unit and only 1W comes out the other end, and often times barely.

Now the best part! The FCC limits transmission power anyway! You want to charge 10 cellphones at their rated 12W slow charge? You actually CANNOT. FCC doesn’t allow an antenna in any form to push that much power without licensing. And I mean amateur radio type licensing. Snippet stolen from someone else that I copied a long while ago:

Go look at the FCC rules for a 500W 15MHz transmitter and safe operating distance from the antenna … According to the FCC an amateur 20M station (14 MHz) operating at 500W you need to be 3.4 meters away from the antenna at a minimum … Which means you cannot have the antenna anywhere in the average sized room without subjecting humans and pets to dangerous levels of RF power. This also assumes a 0 db gain antenna (omni-directional). If you are using a gain antenna such as forming it into a beam or making it directional the the safe distance increases to 4.8M for a 3 db gain, 6.8M for a 6 db gain, etc.

There is no way you are going to develop 500W of power at 15 MHz and get it past the FCC … If you drop it to 100W you’d still need a 1.5M safe operating distance so you’d be lucky to get 5W at 15 MHz approved for something sitting under your desk … And that doesn’t even take into account RFI problems if you don’t have a clean Sine wave and are radiating harmonics and perhaps jamming your neighbor’s garage door opener …

So if you can’t even be near the transmitter for fear of actual danger to the subjects… How the fuck are you going to charge things that are in range if you’re not even allowed to be in range?

Gosh and golly, a CES award! Man! Thats just so impressive! Jeeze if they’re doing that well, they must have a really good product! Maybe next year they’ll have refined it so much they win a red dot design award, that would surely be their Fifty-To-One moment! Or maybe even, dare to dream, a JD Power award! Talk about underdog victories!
