What was once seen as the solution to all our CO2 problems, the ability of trees to soak up anthropogenic carbon dioxide, trees has itself been hindered by global warming.

The tiny battery created by Huang and co-workers consists of a single tin oxide nanowire anode 100 nanometers in diameter and 10 micrometers long, a bulk lithium cobalt oxide cathode three millimeters long, and an ionic liquid electrolyte. The device offers the ability to directly observe change in atomic structure during charging and discharging of the individual "trees."

Researchers working with sensors for trees and grape vineyards reveal promise for improving efficiency and reducing resource costs in agriculture.

Herzog and de Meuron have been very busy lately designing some amazing new buildings in Europe, like their Project Triangle in Paris. Their newest design for the Spanish banking group BBVA will be built on the outskirts of Madrid as early as 2013. The verdant green headquarters will feature luscious gardens and will create it's own microclimate by using natural ventilation, evapotranspiration, and the shade of the gardens and buildings to create a cool artificial oasis on a desert-like site. The project is meant to function as a small city, encouraging people to walk and meet within the outdoor spaces. The project is essentially a linear series of 3-story buildings seperated by alleyways and irrigated gardens. The smaller buildings are designed to give employees access to natural light and the outdoors, while the tower rises as a skyward-tilted circle, giving BBVA a presence in the Madrid skyline. The courtyard located around the tower is planted with shady trees and features a large basin of water that serves as a resevoir and humidifies the air.

seems like just yesterday I was talking about smart grid stuff. There's more news: Tendril Networks, a smart grid start-up, has announced all the goods on its networked in-home energy display, called Tendril Residential Energy Ecosystem (TREE).
