In these eco-conscious times, we’re all trying to save energy. But how can we tell if we’re doing it right? After all, it’s fine washing your smalls at 30 degrees, but the effects may be somewhat negated if you drive a 4×4 to pick up the papers.
Enter MagnifiSense – a piece of wearable tech developed by researchers at the University of Washington. It’s designed to detect the different radiation patterns emitted by household objects, from laptops to microwaves, remote controls to electric toothbrushes. Even cars and buses. So it can tell which devices, and how much energy, you’ve used throughout the day.
It’s a bit rough around the edges: the prototype is clunky, and too big for anyone to wear without looking like an extra from RoboCop. But in early tests, it can already identify 25 out of 29 household objects. And it could go beyond energy saving: carers could use it in nursing homes to track the behavior of elderly people. Of course, the main thing is that dad can finally work out who constantly leaves the upstairs light on.
