California study is NOT about technological limits. Why glass is 100% full
A recent state sponsored study shows that California could reduce its greenhouse gas emissions 60% compared to 1990 by 2050 with today’s technology(pdf). That has sparked a debate. The glass-half-full crowd, among whom I usually count myself would argue that if we have the technology today to achieve a 60% reduction, if we start implementing […]

Can today’s technology tackle climate change? Who cares?
Let’s ponder the real questions.One of the most heated arguments among climate policy analysts is over the following question: “Do we currently have the technology we need to tackle climate change?” For brevity’s sake, I refer to it as the “enough technology” debate.

The creative genius of Occupy Wall Street
Photo: Paul SteinWhat are cities for, anyway? There are as many answers as there are people who love (or hate) cities. They are engines for economic growth, if you ask economist Ed Glaeser. They are breeding grounds for human innovation, if you ask physicist Geoffrey West. If you’re a dictator or a despot — or […]

Facebook is building a renewable-powered mini-town in the Arctic
Facebook is building a server farm in northern Sweden, on the edge of the Arctic circle. The average temperatures there are so cold that they won't need to use anything but the outside air to cool 600,000 square feet of servers. But even so, the server farm will use as much power as 16,000 homes. […]

Carbon-eating paint could clean air and strengthen buildings
Okay, now this one really sounds fake: Scientists are working on a carbon-eating paint, which would be capable of turning emissions into limestone. In other words, it would let buildings eat carbon and then use that fuel to grow, like a living thing. The secret is synthetic chemicals that behave like microorganisms. Their creator calls […]

Disadvantaged teens build 160 MPG hybrid car
West Philadelphia High School has a dropout rate of more than 50 percent, and 85 percent of students are low-income. But instead of making trouble in their neighborhood, getting in one little fight, or even shooting some B-ball outside of the school, a team of 15 dedicated West Philly students built a badass hybrid car that gets 160 miles to the gallon. Then they entered it in a contest where it beat the pants off cars built by fancy Ivy League engineers.

Make a speed-displaying vest for cycling at night
There are a lot of bike accessories that will let cars know you're there. But it can still be hard for them to tell whether you're speeding up or slowing down — which can make it tough for even a well-meaning driver to keep a safe distance. Mykle Hansen's speed vest is designed to reduce […]
