Lots of apps this week… for Freecycling, sharing your juice with electric vehicles drivers, and teaching the kids about rainforest ecosystems.

  • Outlet sharing for electric vehicle owners: The new PlugShare iPhone app helps EV drivers find charging stations… including home owners that will spare some electricity. They’re working on an Android version. (via GreenTech Pastures)
