Hello guys,

Check this out.

The WISP (or Wireless Identification and Sensing Platform) sidesteps all the issues with finding wired power and adding bulky batteries to smart objects by harvesting power from radio waves. It doesn’t even need any special wireless power equipment; just a regular off-the-shelf RFID transmitter. The WISP can pull enough power out of thin air to power a modest processor, but it’s not going to compete with your computer or even your smartphone. The creators say it’s got about as much processing power as the Fitbit — enough to run sensors and transmit data.

Interesting, but to run continuously it must have the radio transmitter 0.5m from the unit.

But I guess this type of harvesting will gain popularity.

Yeah that's a weak point. This technolgy seems to grow fast and will save a lot of effort in industry and IOT applications.
