should be noted that he is hyping about two completely different technologies
the first is magnetic resonance, which is just magnetic fields causing a resonation to generate electricity within it's field
and the other is radio frequencies, which counter to what he says, IS dangerous in large power values - as in cancer
so it's not something you want to hang on your wall and project across the entire room, but is fine to use as a lowpowered tabletop where you put your phone or controller to charge as it dissipates at larger distances


1:1 transfer would be technically impossible even with wires, but even more so when you have to convert it back and forth
especially as the sending unit has no knowledge how the power it transmits is being consumed, if at all, so it's an always-on powerwaster
i hope there's some tech in development that would allow appliances to communitcate with the transmitter and only request specific amount of power when necessary

i don't see any technical reason to be only directional, other than being a lot more efficient
i guess optimally you could put it in your ceiling light fixture to power the entire room
remains to be seen how this tech evolves
personally i'll stay away until power consumption gets under check, and then wire my work desks with it so i can forget about charging my phone/laptop/mice

Maybe it's just me, but this whole video...the way it's edited, the dialog that is heard, the basic reactions of the participants and the extras, etc...seems really really staged.

Like I said, maybe it's just me, but after the first viewing my gut said "fake". If it is totally legit then I think the cop did step way over the line...however I think very few of us know what it feels like to walk close to the line every day. I used to play in a tabletop rpg with a cop (he had his pistol on him even when we were playing...it was very surreal) and he and I had some very frank discussions about his profession. When I first met him I thought "Whoa...this guys a giant dickhead." Once I got to know him, and more importantly once he got to know me my opinion changed quite a bit. We're still friends and I have a mountain of respect for him, and a better picture of what its like to walk in his boots...every day. One of the most memorable things that he said to me went something like this:

"I don't think people out in the general population know how it affects your psychology to constantly be reminded of the math. The math of how we [cops]perceive "you guys" viewing us ends up roughly like this.
-75% of the population thinks we're automatically an asshole and are only around to harass them
-20% genuinely hates us and will do anything to hinder or foil us without actively committing a crime
-3% are just waiting for their chance to shoot us and get away with it
Lastly there are the 2% who seem to appreciate what we do and generally try to be as helpful as possible...and those two percent are almost universally military, ex-military, civil servants of some kind or someone who is already committing some crime that we probably wouldn't give a shit about but they're scared out of their continence that we might catch them.

If the math looked like that on my occupation I might come across as abrasive and callous after a while as well.

From the YouTube page:
"The reactable, is a multi-user electronic music instrument with a tabletop tangible user interface. Several simultaneous performers share complete control over the instrument by moving physical objects on a luminous table surface. By moving and relating these objects, representing components of a classic modular synthesizer, users can create complex and dynamic sonic topologies, with generators, filters and modulators, in a kind of tangible modular synthesizer or graspable flow-controlled programming language.

This instrument is being developed by a team of digital luthiers (Sergi Jordà , Martin Kaltenbrunner, Günter Geiger and Marcos Alonso), at the Music Technology Group within the Universitat Pompeu Fabra in Barcelona, Spain."

There's already another video on here about this table. This one explains what the different objects do and how they are used.
