Networked Fridges 'Negotiate' Electricity Use

An anonymous reader writes "Researchers have developed a way to network household and commercial fridges together in a distributed peer-to-peer fashion that lets them 'negotiate' with each other on the best time to consume electricity. A retrofittable controller is attached to each fridge and then a temperature profile is built around the unit. The controller enables communication between other fridges on the network and also the power source. It enables fridges to work together to decide when to cool down, and thus consume power, based on how much surplus power will be available, and to anticipate power shortages and change their running schedules accordingly to use as little power as possible during these times."

    This probably isn't pitched at householders. I think it would be great for supermarkets, cold warehouses, booze shops, chemical plants etc... people who need commercial/industrial levels of refrigeration.

    If you extend it this could actually be useful...

    Imagine you have a wind generator on your roof and several appliances connected. If the generator can't power all the devices simultaneously then they could negotiate with each other to smooth out the demand.

    eg. If I put the kettle on to make a cup of tea the fridge could switch itself off for a couple of minutes. If I step in the shower all power can be diverted to the water heater, etc.

    On a larger scale, smoothing out the demand could avoid building power entire power stations. This probably won't happen for the next 100 years, but one day it will.

    How does a post where it is clear that the poster didn't RTFA get modded insightful?

    Moderators never RTFA either.

    Fridges as we know them are pretty sad contraptions with no shortage of room for improvement. They put a whopping big heat source under the chamber they're trying to keep cool. They use room air from the hottest part of the house, even though in most homes that room is a foot or two away from outside air that is much cooler, if not actually even cooler than the fridge interior should be. In general, they're an agglomeration of kluges and marketroid idiocies. So yeah, this could be a key part of a rethinking of what a fridge is and how it works that could eventually cut power usage by as much as eighty to ninety percent. The same could be said of quite a lot of appliances and HVAC components. Hell, done right, we now know that comfortable homes can be built that require no conventional heating or cooling systems at all.

    Kinda makes you wonder why we're supposed to need this "smart grid" for all this massive increased demand we supposedly have no way to avoid, doesn't it?

  5. And you fail the reality test again. by RustinHWright · · Score: 4, Insightful

    What's your point? There are thousands of things that people "could" do that they don't. They could superinsulate their homes with dirt, straw, and a few weekend days. They could teach their kids the basics of astronomy in an afternoon or two. They could all show up at the polling place and vote for every single election. Hell, we could all build cantennas and have free wireless in every city in the world by the end of this week.

    Reality isn't about what people in theory could do. It's about what they will do. And out here in the real world less than one percent of the population has the skills to do what you're suggesting and less than one percent of that one percent actually might. No comparison to a plan like this, not even taking into account the fundamental issues of determining protocols and load calculations.
