The TidGen Power System takes advantage of one of nature’s most consistent energy sources: the tide. It sits on the floor of a bay or deep river, where water rotates foils that drive a permanent magnet generator, sending roughly 150 kilowatts of electricity to shore. The first TidGen unit, installed off the coast of Maine last year, was the first ocean-energy project of any kind to connect to the U.S. grid.

When people describe the Internet of Things, they’re referring to a network of Web-enabled devices that speak to one another. In the home, that could mean a phone that talks to a garage-door opener or a thermostat that talks to motion detectors. While these smart devices might represent someone’s preferences (I want my lights to glow blue), they don’t necessarily represent needs (I’m tired, I’m hungry, I’m drunk). For a heater to know we’re cold or a vending machine to know that we need an apple and not a bag of Funyuns, those devices need to talk directly to us.
