magnetic induction or qi chargers let
you just plonk down your phone on a little pad to
get juiced up which is really cool way better than wires
but they only work over very short distances
and they need to be correctly aligned for optimal efficiency
well what if i told you that there's a better way
what if i told you that this speaker right here
and these trains going around me are all
being powered by that space-agey looking light fixture
up there that there is the prototype of why
charge's long-range wireless power delivery system
and holy is this thing ever cool
cablemod's configurator service makes it easy to customize and order cables for
your rig and customers in europe now have their own configurator where
cablemod handles all duties import taxes and documentation check it out at the
link below so this right here is the transmitter and although i guess
technically it could work if we just plugged it in while i'm holding it i
definitely get tired of hauling it around and also this is the only
prototype in existence that can deliver
the amount of power that we are going to need today so if i dropped it
that would be pretty tragic i wouldn't do that
deploying the transmitter is surprisingly simple if you have a drop
ceiling so this prototype is actually held in place by these magnets
and zip ties this is for quick and easy testing but
production models should have more permanent fixtures
once it's secured all we need to do is plug it into a regular dc power source
okay so this light right here is just
a regular light and then this one around the rim is more of a status indicator so
while it's booting up it blinks blue and then once it's green it means that it's
actually good to go the really cool tech though is actually
this black bit in the middle which is an infrared window behind which is an ir
transmitter and then this right here is
also an infrared window and behind that
is a receiver so if i just put this let's say for example right
here and it does need line of sight
give it a second
so if i just take this phone and place it
let's say right here on my ladder and boom
it's charging and if you look up here the status
indicator changes to solid blue but how is it doing that
from up top the transmitter is actually
projecting some very high energy
infrared light and the receiver is basically like a
solar panel so there's a special photovoltaic cell in here that is tuned
to the infrared beam that the transmitter is outputting and now i know
what you guys are thinking i was thinking the same thing
is this entire room being blasted with
infrared radiation right about now am i going to turn into like a mutant more
importantly will my tv remote stop working
the answer is no not at all so the
receiver has a very specific signature
that the transmitter looks for and when it sees it it shoots out a very
thin ir beam basically like a laser directly at the
receiver which is pretty cool
but what makes it loads better is the transmitter's ability to track a moving
receiver so i thought that this demo was smoke and
mirrors when i first saw it back at computex last year
but these trains right here can be fully
powered by the transmitter up in the ceiling giving you some idea of how
quickly your phone or your other device could be
moving around the room and still be powered and or charging and to prove
that the trains have no batteries the instant the beam is broken
the trains stop once line of sight has been restored it
just takes a second or two and then power transmission will resume this
means that there's no way for a person or like your eyes or something to be
exposed to the high energy beam and the fda and other international safety
regulators have already given it the seal of approval
plus you get to feel like a magician
okay so what you're probably wondering now though is how much power
can it actually deliver well why charge brought two different
models here there's this smaller one that's aimed more at like internet of
things applications this can deliver about one watt while having a smaller
footprint making it a little more subtle then there's the larger one that we put
on the ceiling that can do up to three watts
so this is one of their receivers hooked up to a speaker
not bad
but if we try to go too high
it tanks out a little bit now let's hook up a larger receiver that
they've got here this one does one and a half watts
and see how much louder we can go
not bad that's too shy of max volume
but i mean if we're being entirely honest
here that's still not a whole ton of power and like if i wanted to charge my
phone or heaven forbid a tablet
a what and a half isn't a ton and putting a case like this on it is
probably not that practical
fortunately this guy is more of a proof of concept
and why charges first commercial product makes a lot more sense
so this guy right here is a qi charger with regular usb on the underside that
can be placed anywhere in the room and still receive power so for something
like a coffee shop they could offer charging at their
tables without running cords to every
single one of them and that way if someone wants to
relocate the table to sit with their friends it's totally not a big deal they
would just kind of go like that and bippity boppity wham it is wirelessly
charging what makes it really well integrated is
the fact that it sits actually in the table like this like obviously we're not
going to drill a big hole in our table in order to do that right now and the
fact that it has a battery inside it so
that acts as a buffer so that battery can trickle charge all day and all night
and then when someone plugs in or puts their phone down on the pad it'll be
able to charge at more than just you know three quarters of a watt and it
won't matter if somebody you know is in the middle of a really really you know
fascinating conversation and blocks the beam for a little while
and this is just the beginning i'm really excited to see where this
tech is going i mean just how much power will they be able to get out of these
systems in the future could receivers just be built right into
your phone or tablet and a little with a little you know window right there i
mean that would allow your device to trickle charge all day long if you're in
range of a transmitter maybe this will finally be the solution
to what has been the biggest problem with smartphones
those pesky headphone jacks no not those battery life
