What’s holding back the Internet of Things? Power | GeekWire

A tether or a battery? The growth of the Internet of Things (IoT) is limited by these two unsatisfying options. Have you ever wondered what provides power to all of those hotel room card key locks? It’s batteries that die and have to be changed. Most video surveillance systems are tethered, mobile phones use batteries, RFID readers are tethered, drones usage is limited by battery life, and so on. Why are smart thermostats and doorbells selling so well? It’s because the power supply is already there. Show me a source of power and I’ll show you a great IoT application.

Try to imagine what the world would be like without these constraints. Of course, we’d all love our phones to be fully charged all of the time, but wireless power has implications well beyond that. Imagine lightweight powerful lawn mowers and yard tools that just work; drones that could stay aloft indefinitely; industrial sensors that could be attached to anything, anywhere; or security systems that could be deployed quickly and easily. IoT devices would crop up everywhere, helping us in ways that we haven’t even thought of yet.
