It’s a place where your refrigerator could be connected to the Internet, so it could order groceries when they ran low. Your dinner plate could post to a social network what you’re eating. Your robot could go to the office while you stay home in your pajamas. And you could, perhaps, take an elevator to outer space.

These are just a few of the dreams being chased at Google X, the clandestine lab where Google is tackling a list of 100 shoot-for-the-stars ideas. In interviews, a dozen people discussed the list; some work at the lab or elsewhere at Google, and some have been briefed on the project. But none would speak for attribution because Google is so secretive about the effort that many employees do not even know the lab exists…

Other ideas involve what Google referred to as the “Web of things” at its software developers conference in May — a way of connecting objects to the Internet. Every time anyone uses the Web, it benefits Google, the company argued, so it could be good for Google if home accessories and wearable objects, not just computers, were connected.

Among the items that could be connected: a garden planter (so it could be watered from afar); a coffee pot (so it could be set to brew remotely); or a light bulb (so it could be turned off remotely). Google said in May that by the end of this year another team planned to introduce a Web-connected light bulb that could communicate wirelessly with Android devices.

One Google engineer familiar with Google X said it was run as mysteriously as the C.I.A. — with two offices, a nondescript one for logistics, on the company’s Mountain View campus, and one for robots, in a secret location.
