Green tech finds: the clean development edition

If you can power your phone with sunlight, and carry water purification equipment on your back, is there any need for large-scale, dirty utilities in the developing world? Those ideas and more in this week’s green tech finds.

What’s your neighborhood’s Bike Score?: The five-year-old Walk Score online service, which rates walkability of neighborhoods, cities, and addresses, now offers a similar metric for bicyclists. The new Bike Score is available in ten cities (and, apparently, Minneapolis is more bike-friendly than Portland – who’da thunk it?). (via The Atlantic Cities)

Charge up your home with a shower: Mexican design firm Hierve thinks a lot of power is going down the drain – that water moving through your pipes could produce electricity. Their Hydroelectric Lamp concept harvests that power much like a micro hydro system. (via Do the Green Thing)

Solar phones connecting Kenyans with each other: Safaricom’s mobile phone with embedded solar panels ensures that Kenyans can always charge up and stay connected (well, as long as the sun’s out).

Become an illegal dumping detective: Well, sort of: the new TrashOut app uses location-based technologies to allow you to report illegal trash dumps that you find. (via Earth 911)

London Olympics will recycle vinyl buildings: The bad news – many of the temporary structures for London 2012 are being built from PVC. The good news: games organizers plan to recycle as much of that vinyl as they’re able for similar structures at the 2012 World Cup in Brazil. (via Inhabitat)

Affordable prefab homes: Prefabricated homes have become all the rage with the sustainably stylish set; they’re still a bit pricey for the rest of us, though. Connect:Homes has managed to retain the style while dropping the price by increasing the amount of construction done at the factory: up to 90%. (via Green Living Guy)

The water purifying backpack: Pang Teh Say Chun’s Skoon concept concentrates a lot of water purifying power in a little space: enough to carry on one’s back. The Skoon was designed for use in the developing world. (via Earth Techling)

We’re betting you didn’t find anything cooler this week on the green tech front. If we’re wrong, prove it: share your find in the comments.
