Local Warming follows you: these infrared spotlights act like artificial 'suns' to keep you warm

10X more energy efficient than traditional heating
What if instead of heating a bunch of empty space, you could keep people warm directly? That's what MIT engineers are working on, trying to find a more energy-efficient way to keep people comfortable in large interior spaces - often in largely empty buildings - that cost a fortune to heat (and thus use a lot of energy). And I'm not talking about handing out blankets and warm sweaters at the front door.MIT’s Senseable City Lab started from the realization that there's a "dramatic lack of correlation" between how many people are in a building and its heating-system energy consumption. And because commercial buildings represent over 20% of US energy consumption, this is a huge deal. So how could you put heat only where people are, rather than just heat up the whole thing all the time even if nobody's there to notice?


The researchers believe that "a fundamental shift in climate control strategy towards occupant-localized heating will achieve an order of magnitude improvement in heating efficiency." While it might seem like science-fiction, as long as people are kept warm, I doubt most people would mind, especially if this uses 10x less energy.
Of course, this type of system would make most sense in areas where there's a huge volume of air and a low density of people. Building lobbies and atriums would be ideal, while densely packed cubicle farms would probably still use traditional heating systems.
We can imagine all kinds of ways that this could be optimized, like for example, maybe optics on the infrared spotlight could send a wider beam to heat up a group of people standing close to each other while narrower beams (thus less wasteful) could be used for single individuals. Maybe a standard communication system could be devised so that people could set up preferences in their smartphones (ie. I like it when it's 72 degrees fahrenheit) and Local Warming systems everywhere would get that signal from your phone and try to keep you at that subjective temperature. The possibilities are many.

But the real question is: HAL9000, is that you?
