Living on 2,000 watts is harder than it sounds--that's roughly a sixth of the average rate of energy consumption in America.* But GFRY Studio , a graduate course at the School of the Art Institute of Chicago, challenged students to devise products for an ultra-low energy diet. Their solutions were displayed in Milan recently, and range from the abstract to utilitarian.
Cara Ellis' Digeotruss Structural System , fabricated using digital routing, was used as the lattice for organizing the individual projects:
Bo Rodda 's Active Cloud Lighting System  would cut energy use by reacting to movement, throwing light only where needed--down a dark hallway, for example. Or, with the flick of a wrist, you could turn on a reading light:
Matthew Stewart  designed a solar shade system that uses discarded wood, and a computer program that analyzes a building's orientation and shape, to determine eqactly where shades would most reduce energy use:
Jungwhan Chei's Deep Space Lighting  is bendable, and customizable to varying needs:
Watt Watch , by Daniel Sommer, uses Energy Star data to compare the power consumption of appliances around the house:
Also by Daniel Sommer, a folding garment bag for bicycle commuters--why doesn't someone already make this?!
Tuan Nguyen's Urban Sun  is a computer program that calculates bulding heights within a city, to optimize sun exposures (though don't expect urban planners to use this one to raze city blocks any time soon):

*Thanks to every one who chimed in to comment on the Watt/Kilowatt issue. Just to clarify, the 2000-watt idea apparently comes from the 2000-Watt Society , which aims to bring world energy consumption down to 2,000 watts ---that's joules per second--by 2050. Don't confuse that with kilowatt hours. Many people have pointed out that you could easily live on 2000-kW per hour. Long story short, a group of extremely OCD Swiss scientists studied energy consumption around the world in kilowatt hours, did lots of division, and found that Americans, for example, consume 11,200 joules per second--or 11,200 watts. They then formed the "2000-Watt Society"--which seems to have inspired the name of this exhibition. Please, no more comments about energy bills! Phew. I'm glad that's over.
