Concrete is everywhere in construction, so I like to note what’s happening to make concrete “greener.“ CarbonCure Technologies, Inc. licenses technology in North America to make, for example, carbon-absorbed concrete blocks and other precast products. Basically, CO2 is injected during curing — making limestone — with the end result being a stronger, greener masonry and other precast products.
South Carolina-based Firefly Power is one of 20 other social- or environmentally-inclined companies presenting at the i2i Awards program in conjunction with SXSW Eco in Austin through Friday, October 5, 2012. The company makes lightweight small wind turbines out of carbon-fiber blades in the vertical axis form. The residential unit is rated at 1.8 kW, weighs less than 60 pounds, cuts in at 10 mph winds, and is expected to sell for about $7,000, according to Firefly Power.
This is an 800-square-foot home in the River Road area in north Eugene. It was designed by Nir Pearlson and built by Six Degrees Construction for owners Rob Handy and Julie Hulme, who were inspired by The Not So Big House and other books by Sarah Susanka, FAIA. It turns out the owners upsized their situation by deconstructing an existing 620-square foot house built several decades ago, according to The Register-Guard.
I was noodling some recent journalist potshots about headlines for “the greenest …” when I landed on this video piece from the Nightly News. NBC’s Kiko Itasaki wonders if this home in Unst, one of the northern Shetland Islands of Scotland, is the greenest in the world. Everyone knows the question has no answer, but I think Michael and Dorothy Rea have accomplished something worth noticing that’s for sure.
I’ve been watching plug-and-play solar systems like the one offered by SpinRay Energy to see how viable and affordable these can get. It turns out GoGreenSolar.com just unveiled a similar system called the SunPlug Plug n’ Play Solar Kit. The kit includes one 235-watt polycrystalline panel, a 120 VAC/60 Hz grid-tie inverter, racking mount, WiFi module for monitoring, and a connector to plug directly into an AC outlet.
