A traffic light that knows the difference between bikes and cars

No matter how strong a cyclist's legs are, a bike cannot go as fast as a car. Duh, right? But traffic lights are not as smart as humans, and they do not instinctively understand that. So they’re programmed to assume leg-powered vehicles can make it safely through lights in the time allotted to things with engines. Luckily, some human was smart enough to invent the Intersector --  a traffic light that respects the difference between bikes and cars.

This electrical socket spits out your power-sucking plugs

The PumPing Tap does not like wasted power. It's an electrical socket with a spring-loaded ejector seat, which pops plugs right out if they're slowly sucking energy when not in active use.

The idea is to combat vampire power, the massive amount of energy slowly sapped by idling gizmos, like microwaves that aren’t cooking or chargers that aren’t charging anything. The PumPing Tap (which is still in the design stage, sadly) monitors the flow of energy, and if you don't use a device for 10 minutes -- ptooie! -- it's unplugged.

Chief of Staff Bill Daley resigns, environment rejoices

Greens have been singing "won't you go home, Bill Daley" for a while (turn-of-the-century music jokes, anyone? No?). The now-former chief of staff was the guy responsible for kneecapping EPA smog regulations, and he was generally considered to be in the administration merely as a sop to Big Business. So now he's resigning, and probably the next guy will be an improvement? We hope?

Critical List: Canadian minister hates tar-sands opposition; airlines charge for free carbon permits

Canada's natural resources minister is not happy that all of you with your "radical ideological agenda" think Canada's turning into a creepy petrostate.

Japan is releasing those three whaling activists who boarded a Japanese whaling vessel.

Carbon emissions are delaying the next ice age.

David Bowie riding the subway

The Thin White Duke turned 65 (I KNOW) yesterday, and Flavorwire has put together a slideshow of him doing normal stuff, just to prove he can. Here he is making use of public transportation, even though he could totally summon a shimmering gargoyle to fly him to wherever he's going. Going car-free: It's cool! David […]

Mosstika’s living graffiti is amazing

Street art isn't just gang tags -- it can revitalize and beautify urban spaces, increase community identity, and even be a form of nonviolent protest. The work of Edina Tokodi kind of does all of those, plus it's about as green as graffiti can be: Tokodi's studio Mosstika makes street art from living moss.

U.S. becomes first country on Earth to limit catch size for all fish

In a rare bipartisan move -- the policy was initiated under George W. Bush and finalized under Obama -- the federal government has enacted catch size limits in order to prevent overfishing of coastal seas, reports the Washington Post.

Super scrubber turns CO2 into fuel

Boffins at the University of Southern California have created a plastic-based, sand-like solid that absorbs CO2 from the air at room temperature and releases it at 185 degrees F, reports the Christian Science Monitor. Think of it like clumping cat litter for air — it sucks up CO2 and makes it easily removable. It can […]

Trick out your Kindle with solar panels

Screwdriver-and-soldering-iron types have probably already made their e-readers solar powered, but what if you didn’t have any Schottky diodes lying around? SolarFocus has the technologically inept among us covered, with a Kindle cover that charges your device with solar panels. An hour of full sunlight can charge your Kindle enough for three days of reading, […]
