Green tech finds (9/9/10)

A bee beard for David Cameron, subway energy harvesting, and using search technology to identify endangered species… this week’s green tech finds.

  • The Wolverine solar cell: Researchers at MIT actually looked to plants, not the X-Men, when creating a solar cell that “heals” its own UV damage.

  • Tweet for the honey bees: British marketing firm LBi has created a “twittition” (Twitter petition) to support honey bee populations in the UK. Each tweet added to the petition adds a bee to a “bee beard” on a likeness of Prime Minister David Cameron (shown above).

  • A green KOA: Campground owner Tony Fassi has made major cuts to his energy spending with the addition a solar pool heater, and an evaporative lagoon for wastewater treatment.

  • Finnish electric cars: An international collaborative of companies is planning to design and manufacture a new electric car in Finland’s Central Ostrobothnia region.

  • The regenerative braking subway: Regenerative braking is fairly common on hybrid and fully electric cars; Philadelphia’g going to try to harness some of that energy from its subway system, and send it back to the grid. (via Ecogeek)

  • The 100 mile EV battery: Ford claims that the battery system it’s creating for its Focus Electric (due out late next year) will give the vehicle up to a 100 mile driving range. (via GreenTech Pastures)

  • PageRank™ for food webs: What’s the most important species in a food web (the network of predator-prey relationships in a given ecosystem)? Ecologists Stefano Allesina and Mercedes Pascual believe you can find out through a tweaked version of Google’s PageRank algorithm. (via Planetsave)

  • Net-zero affordable housing comes to the Lou’: And, finally, on the home front — Capstone Development Group‘s net-zero energy affordable housing development, Lexington Farms, will break ground in Jerseyville, IL (just outside of St. Louis) next week. (via Ecopreneurist)
