Cool idea of the day
Floating wind turbines that can be placed farther out at sea (and in heavier wind) than typical anchored offshore turbines. Next: high-altitude wind!

Can we shoot concentrated solar power down from space?
CNN takes a look an energy long shot that could change the game on climate change: space-based solar power. The idea is to launch satellites covered with solar panels up into geosynchronous orbit, where the sun is always shining, and beam the power back down to land-based receivers. A 2007 Pentagon study concluded that “a […]

Sustainability a big theme at the World Science Festival
What do vertical farms, green roofs, soft cars, breathing walls, and Dongtan, China, have in common? They were all subjects of discussion at Friday's Future Cities event in New York City, part of the four-day 2008 World Science Festival.
To a packed house, Columbia University microbiologist Dickson Despommier described his vision for feeding the planet's burgeoning, and increasingly urban, population. The vertical farm takes agriculture and stacks it into the tiers of a modern skyscraper. Instead of stopping at the corner pizzeria for dinner, Despommier suggested, you could pluck a nice head of lettuce, maybe some corn, and some tomatoes for a big salad, all in your own building, on the way to your apartment. You can't get fresher or more local than that.
According to Despommier, the farms will be "grown organically: no herbicides, pesticides, or fertilizers." (Of course, being indoor, there won't be many insects to spray for.) The farms will also require much less irrigation since all water can be re-circulated, and they'll curb the growing pressure to turn forest into farmland.
The vertical farm sounds (and looks) pretty amazing, and certainly Despommier deserves much credit for thinking boldly ... but I was left with several questions.

Recycled plastic products gain ground
The New York Times has an interesting article up about recycled plastic products. They're profiling a company called Recycline, which makes those bright green recycled plastic cutting boards, strawberry red colanders, and even toothbrushes.
According to the article:

Drink beer, fight climate change
Many efforts to fight climate change involve some kind of sacrifice. This invention, however, merely requires the drinking of lots and lots of beer. I see it as a game-changer in the debate over the best way to incentivize a solar market.

(He’s going to do it in Denmark as well.) (A side note: this meeting […]
