Making energy use visible

Photos courtesy of Harry Ward We’ve looked recently at water taps with meters built in, the thinking being the ‘speedometer’ approach to shaping users’ behaviour – making users aware of the scale/rate/level of some activity should cause them to adjust that behaviour. A number of […]

Full, tilt

Full, tilt

Jan Hoekstra’s Balancing Bowls for Royal VKB (via Boing Boing) are an interesting ‘portion control/guidance’ solution – as Cory Doctorow puts it: The tilt is tiny, all of 3 degrees, and the net effect is very satisfying — you gradually add snacks to the “light” […]
