Spray-on antenna wants to pump up your phone's signal power

Remember those silly antenna booster stickers they used to sell for cellphones that really did nothing? Well now there's a new concept that does something similar, a spray-on booster that promises to give you an improved signal in a can.

The spray was developed by a company called Chamtech, which claims it will coat any surface you spray with it with thousands of "nano capacitors" that charge and discharge in sync with the signal to improve antenna efficiency. Company CTO Rhett Spencer claims that the spray can turn any surface including buildings and trees into efficient antennas, and even that it can replace unsightly cellphone towers.

To be honest, my B-S detector started beeping as I read some of this stuff, but what do I know about antennas? Still, it's a little weird that they chose a name that could easily be mispronounced as sham-tech. The spray was presented at Google's recent Solve For X event, where I assume there was some vetting of the presenters.

The video is their pretty dry presentation from the Google event, and it shows some the tests they did to determine the spray's efficacy. If it really does work like they claim, these guys are going to be zillionaires.
