Wireless power

Tesla technology coming to life: pulling power out of the ether.  This technology may not provide power as Tesla had imaged, but it is impressive nonetheless.  The technology has the potential to capture up to a couple of milliwatts from RF broadcasts (radio, TV, radar, etc).  Combine this with other power generation/collection (such as solar or small scale wind) and a good storage technology (supercapacitor) and this might be a way to provide power small sensors.  Imagine having thousands of weather sensors providing massive widescale weather information.  Maybe this could improve weather forecasts?

Now, if we could only increase the current power available over electricity over glass, my life would be easier.
