Visual Voltage

Visual Voltage is an inspiring exhibition by a group of Swedish designers and engineers, of technology that helps people visualise their energy use in the home. We've just installed a meter that tells us how much energy we're using - you can switch the washing machine on and see the hourly cost shoot up. But it's not very compelling, and you forget about it quite quickly. These devices are more visceral - some of them actually work on an emotional level (such as the energy flower than blooms when you use less electricity). The powercord (below) looks like it's wasting energy, and you can't wait to switch it off. The energy clock maps your households usage, and shows you the times when you might need to change your habits.

The exhibition is touring at the moment, but there don't seem to be any UK dates.
