Green tech finds (2/3/11)

T-shirts that detect pollution, wind power from transit tunnels, and solar power in coal’s heartland… your green tech finds for the week.

  • The pollution-detecting t-shirt: NYU grad students Nien Lam and Sue Ngo’s Warning Signs t-shirts display either a heart or a pair of lungs that change color according to the levels of carbon monoxide in the air. Watch it work above… (via Green Energy News and @greeneconpost)

  • All renewables by 2050? A brand new report from WWF claims we can get there, “…with only isolated residual uses of fossil and nuclear fuels.” (via Mail & Guardian Online)

  • Home energy management the next big thing? You might think so judging from the news on the topic coming out of the Distributech smart grid conference in San Diego… Heather Clancy has a run-down of various products and services she’s seen announced.

  • Pre-fab, flat-pack disaster housing: The easily transportable Ablenook concept also has solar panels integrated into the roof. Envisioned for disaster shelter, the designers also believe their concept could work for homes and portable classrooms. (via Inhabitat)

  • Transit tunnels as wind turbines: That’s the idea behind Alessandra Rapaccini and Giacomo Sanna’s CitySpeed Turbine, an entry in the GE Ecomagination Challenge. (via Fast Company)

  • Solar power in coal country: A small, but significant, solar power system will open up today in Williamson, West Virginia… which identifies itself as “The heart of the billion dollar coalfields.”

  • Online marketplace for low-carbon cars: British-based EcoForecourt is a lot like other sites for buying and selling cars… except that it limits listings to cars “with emissions of 130g/km C02 or less.” (via Springwise)

  • Clash of the titans — solar vs. wind: Washington state-based Inland Power hosted a head-to-head experiment between the two giants of home renewable power… and found that solar’s generally the better bet right now… (via Calfinder’s Residential Solar Blog)
