From a green ride to a clean (hand-cranked) shave, it’s all here: this week’s green tech finds.

• Solar that doesn’t stand out: Or, not as much, anyway… Iowa’s Powerfilm has developed “thin, flexible solar sheets that can be integrated with architectural building materials.” (via Springwise)
  
  
• Eco wifi: Australia’s D-Link has announced its Green Ethernet^TM technology which “automatically detects link status and network cable length, then adjusts power accordingly.” It’s also allows a user to schedule wireless up time (like thermostats).

Techies rejoice! Here’s your weekly run-down of some of the cooler green tech stories out there…

• Free energy? There’s a ton of it out there — 7 quadrillion BTUs — in the form of wasted heat. The Department of Energy has announced funding opportunities for R&D on how to tap this massive source of energy. (via Cleantechnica)
  
  
• NYC — the wind energy capital? It seems counterintuitive, but the Carnegie Institution and California State University have found that high-altitude winds, which are concentrated over the Big Apple (among other places), “contain enough energy to meet world demand 100 times over.” (via Green Living Ideas)

Deutsche Bank’s online carbon counter

Phones, flashlights, and sweet solar-powered rides… all that and more in this week’s green tech finds.

• Funding priorities: Is a national smart grid the best investment right now? Or would local micro-grids fed by renewable power serve us better?
  
  
• More proof that teenagers do know it all: Fourteen-year-old David S. Dixon built “a street-legal quadricycle with a solar-powered electric motor” for a middle school project. (via Gas 2.0)
