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."
That's because you didn't RTFA.
It's about renewable energy and making the most of solar/wind. I.e. ensure that excess solar energy is used up during the day by cooling the fridges an extra couple of degrees so they don't have to use base load power over night.
RTFA, you might learn something.
Well, there's a big difference between lab simulations and real-world trials. The previous paragraph suggests the largest trial they've done with real equipment consisted of seven small fridges and three larger industrial-sized coolrooms.
Also, it's not intended for single locations but rather for "every house in the city". There's little to be gained by smoothing out the energy usage of individual locations, even rather large locations.
