I noticed BuildingGreen added these exterior venetian blinds to the GreenSpec Directory recently. Hella exterior blinds are distributed in the U.S. through Savannah Trims and available in slat sizes of 2", 3.1", and 4". The blinds are aluminum, have lateral tension, and can be controlled manually or electrically. They're slick looking and come in a variety of heights, widths, and colors.
Greentech Media broke news today of a prototype rooftop solar system made for simplicity, shipability, and affordability. The system is being developed by Armageddon Energy and is aptly called a "clover." The clover includes three hexagonal solar panels, a micro-inverter, and a triangular frame. It's lightweight (check out the regular folks below doing installation work) and can generate roughly 400 watts. The company just finished early stage testing and is readying a beta program for further testing.
Transportation is inextricably linked with (green) buildings. And for a number of reasons — peak oil, national security, price gouging, and concern for the environment — the current oil-based transportation system is dying. Its death started with hybrids, and to a certain extent, continued with natural gas vehicles. With the advent of electrical vehicles, we will all witness the slow, prolonged, and painful death of oil-based transportation. Tonight Dateline NBC gave us a glimpse of the next generation of transportation in Tesla Motors. The future of electrical cars is bright, but let's be clear: it's complicated, too.
