Green tech finds (11/5/09)

Bricks, robot fish, and eco-warriors… this week’s green tech finds!

  • Find a green business… and a coupon: GenGreen Digital Media has just added a new feature to its Find Green iPhone app: coupons. Find a business that has what you want (and shares your values), and save some money in the process.

  • Online carbon reduction for builders: the Rocky Mountain Institute has just released Green Footstep, an online tool that allows builders to assess (and reduce) that carbon emissions of building and retrofitting projects.

  • Low-carbon bricks: CalStar Products, Inc., will open a new factor next month to make bricks from fly ash. According to the company, the process to make these bricks will use “roughly 85% less energy than traditional clay brick manufacturing, with an equivalent reduction in carbon-dioxide emissions.”

  • Wind turbine 15.0: OK, I made that number up, but turbines have gone through tons of iterations. Dragonfly claims to have designed the next generation of wind turbine: one that speeds up the air as it moves through, thus creating more energy. (via Green Living Ideas)

  • The solar-powered monorail: a green tech twofer — public transportation that runs on renewable energy. That’s the idea behind the Energy Belt, a concept designed by Iosa Ghini Associati for Bologna, Italy. (via Inhabitat and Eco Tech Daily)

  • LA going LED: The City of Los Angeles has decided to undertake the Herculean task of replacing 209,000 street lights and bus stop lighting with light emitting diodes (LED). The bus stop lighting will also be solar-powered. (via CNET Green Tech)

  • Robotic fish: Michigan State engineering professor Xiaobo Tan believes fish are “very efficient,” so he’s following nature’s lead and researching how to create robotic fish that could monitor water quality. (via Cleantechnica)

  • Are you an eco-warrior? You may be able to find out in the near future: energy management technology firm Tendril Networks has paired up with “a major computer game manufacturer” (not named) to create a game focused on reducing home energy use.

You probably haven’t seen anything nearly as cool as “eco-warriors” or robotic fish this week, but if you’ve found anything remotely close, share it with us below…
