Technology

I doubt anyone is under the impression that it is going to be as efficient as direct power. At least no one paying attention.

Edit: The downvotes lead me to believe a not insignificant number of people don’t understand how energy works.

Efficiency and outright performance isn't always a priority.

A lan cable outperforms a wireless Internet connection in every way, yet most people just use WiFi

I was actually surprised the Bluetooth keyboard and mouse still worked.

This method uses magnetic resonant coupling (vs inductive which is how wireless charging works on your phone). The difference is the transmitter and receiver are both tuned LC circuits that operate at their resonant frequency, which is why this works over the impressive range shown in the video. It would have efficiencies around 80% mark based on what I could find. But yeah for RFI, this would definitely be worse than something like normal Qi charging, which operates in the 100s of KHz, while this operates in the MHz. But I think the manufacturers page says this is FCC certified? So might be not too bad.

It's not - this dude doesn't zap himself even once.

It's a good video though, showing how he integrated everything.

Why would a YouTube channel make an article instead of, you know, making a video, which is their job?

It's a YouTube channel that does high quality DIY projects, and explains the reasons behind the choices made.

Why would this be an article as opposed to, y'know, a video? His job is to make YouTube videos.

I don't understand this obsession some on Lemmy have with shitting on hard-working creative types when they make something in video form rather than creating a blog and publishing articles.

It's an interesting video, you can see the sizes and form factor of the recievers this way much better. You can still skip the parts you are not interested in.

Did you even watch the video? It's a well-produced piece of content from a pretty well-known individual

Because it is bullshit lol.

Wireless efficiency is around 70%-75% max with something like that; EMF and RMF issues abound in any configuration without shielding, which this one has none of. I am surprised anything works.

I don't know about the rest of you, but I'm not willing to pay a 30% higher electrical bill for something like this.

Wireless peripherals and any wireless data transfer protocols are completely irrelevant to the content of this video, which is centred around wireless power transfer.

Also wireless peripherals are pretty great, not sure what you're on about.

Corsair

I believe I found the problem.

Do you remember the exact model? I'm interested in looking into it

it does say on the site for the device that it draws 100W, but in the video he says that there is a 10W minimum draw, so i'm assuming it goes up from there

it also would have very publically been a huge failure. Tesla tended to ignore the science when he didn't like it. It could not have possibly worked

• + Wireless

• - limited range

• - horribly inefficient, increasing with distance

So, there.

We, today, understand how to power something wirelessly. The problem is it's horribly inefficient.

No, they saw a way of profiting from it not happening..

No.

A developer kit is available, but only for R&D teams: https://www.etherdyne.net/evalkit

Its r&d kits only but send em an email and they will probably sell u one

Would seem offly click baity of them to say "it's finally here" if you couldn't...
