Made By Makers has put on their site this personal air quality meter that is wearable and designed so that you won’t be embarrassed to do so.  Purchase of this device, which can be accomplished at fashion stores, results in a couple environmental wins:

• Part of the proceeds go to global warming research
• The device, when eventually no longer used, can break down into recyclable waste
• The device only uses the motion of your body, kinetic energy, to power itself.  No batteries!
