I'd like to know who that guy's electrician is if he asks for $32000 just to install the wall outlets.

Apparently Ossia are claiming 2 to 3 Watts delivered to a device battery within a car interior (re-asked and reconfirmed). While on the one hand they are saying 5.8GHz, they are doing demos at 2.4GHz, and this manufacturer was concerned about what it would do to his product. I told him not to worry about his product, his eyeballs are a larger concern. Ossia's public materials don't give numbers so this is just word of mouth. They do make some ridiculous statements though - here's their founder going through the maths of why you're better building your house with wireless power rather than those expensive wire things. Apparently it will be cheaper, save the environment, and make us all safer if we just change to RF wireless. Not sure how the wireless emitters get their power...

"Real wireless power is power delivered over air, without wires or charging pads, to a device or sensor automatically, without any user intervention. It can be managed and secured via the cloud" [My bold]
Well there's the built in obsolescence right there.

I'm wondering if they're going to pull a "we only supply the component, it's the final product vendor that has to get regulatory compliance".

Ossia had a webinar in December, available (still, go download it fast, before they remove it) on their website.
On ~33:50 they say the transmitter is 10W.
But according to them, these limits are for data communication, not for Ossia.
I almost understood that since it's not communications - it's safe.
the FCC, the entire microwave oven industry, car radars, and even Energous don't seem agree.
also claims in the same webinar 3W @ 5M
BTW, if they can send >1W to >3-4 meters away, they can probably duplicate the Wi-Charge trains or something similar, even with no line of sight.

"If we did not need 80% or so of these outlets, because all of our small devices were instead using wireless power, the electrical installation costs alone for building a home could decrease by 7 to 8%.
Seven or eight percent may not sound like much, but for a $400,000 home, that’s $28,000 to $32,000 of savings."
He claims the fewer sockets saves 7-8% on the electrical installation costs which is probably about right, but then multiplies that 8% by the total cost of the house instead of just the ~1% electrical installation cost, so his savings are 100X too large. :palm:
"you’d need to live in that house for 407 years for the wireless power energy bill to begin “costing” you."
So the 407 years come down to about 4 years, even less if you include the cost of the transmitters and medical bills. :palm:
"Making housing more affordable, and home ownership possible for more citizens, is just one example of the value wireless power brings to society."
LOL. At this rate Ossia will soon be getting their very own FAQ thread. :)

Now that uBeam stopped twitting every 5 minutes we can just use this one
