Paper antennas pull electricity from the air

The air is full of energy -- not in a woo-woo crystal-gazing way, but in a scientific electromagnetic-radiation-from-TV-stations-and-phone-networks kind of way. That ambient energy is just being wasted. But a team from Georgia Tech is developing inkjet-printed paper antennas that could generate enough energy to power a small gadget, right out of thin air.

Painting roofs white could save a year's worth of emissions

Where do greenhouse gases come from?

This chart from the United Nations Environment Programme (click to embiggen) looks complicated, sort of like a traffic sign cross-bred with a banyan tree. But it basically just traces the path of greenhouse gases from polluting industries, through uses, out into the atmosphere. So you can tell at a glance, for instance, that energy industries […]

Amazing bamboo bike is grown, not manufactured

The complicated weave of the Ajiro bike would be work-intensive to achieve through conventional means -- it takes a lot of energy to bend bamboo stalks into shape. So instead, design student Alexander Vittouris tensioned the bamboo over a mold as it grew, then harvested a completed bike frame.
