Bta? isn't W1z the boss?

true, but who says new batteries with lower charging voltages arent part of the design?

new battery chemistries don't pop up overnight.
They have to boost the voltage and thus losing energy in the process.

magical wireless recharging doesnt pop up overnight either, i say we dont rule anything out or make assumptions til we see it in use.

No one bothered because it's impractical.
WiFi signal has too low a level of energy, it's also not directed, meaning this device can use only fractions of the transmitted power.

its still magic until proven otherwise

Well it might work, but I don't see how the charging current can be higher than one digit in mA.

I'm all for it if magic is involved.

Yeah they go through some physics math in the linked article thread and the power gained is insignificant. Something like 20,000 hours to charge a cellphone battery, and that is close to the best case you could expect.

Wow... I have to admit this sounds pretty promising...

Leaving a device in a wifi area (aka my house) to charge would be amazing...
