Smart lightbulb sends sms

Fujitsu's has come out with some interesting technology: smart light bulbs. It needs no coke-cola, no nicotine and no women…not even a QR code. But I’m sure girls would need the 'concept' while trying to text. Damn, this sounds too relaxing…Back to the lightbulb. A signal is engraved in a contact which is part of it. When a light bulb dies, it can then send out the signal via a power line and then to the Internet so one can receive an SMS message saying 'Buy a new light bulb'.
