It costs $1250 for something with terrible efficiency. You could buy an awful lot of batteries for that much money.

Last time I read about this about 2/3 of the energy of the laser disappeared during the conversion to electricity. Has that improved?
Mor says Wi-Charge’s wireless power transfer efficiency is about 15 percent compared to a direct wired connection.
That’s not counting the energy used to power the transmitter’s Wi-Fi connection, status LEDs, and so forth.
Why does the lock, faucet and shades run on batteries to begin with? They aren't portable devices, just spend a few minutes running a damn cable and you never have to care about power ever again.
The coolest thing about this IR laser is the very cyberpunk things a hacker might do with it.
