Tis the season for blog posts about eco-friendly gift ideas, and who are we to argue? Rather than trying for the definitive all-encompassing guide, we'll just mention three products that their PR firms were good enough to send to Earth to Philly for testing. These are all things that would be appropriate for your "green"-oriented friends, or for tech geeks, or preferably for both.
Freeloader Pico - This is a phone charger that's called "freeloader" because it gets its power from the sun (and "Pico" because it's the small unit in this line, I guess). Yes, a solar-powered charger. Great to have with you on the go, in case of emergencies or whatever - though you need to plan ahead to a certain extent as it takes 10 hours of full sun to fully charge, and then 10 minutes to charge your phone (or similar small electronic device).
I was never able to get the ideal conditions to charge this for 10 straight hours, but it did indeed charge up my phone from the exposure I was able to give it, and it's very lightweight and easy to stash somewhere to bring along. Find out about the Freeloader Pico, available for around $26, at freeloaderpico.com
Armpocket - Exactly what it sounds like, a pocket for your arm. Specifically, a pocket in which you can store your solar-charged phone and/or other small items while you run or work out. While the concept is not intrinsically green, the Ampocket is: it "fuses the best of eco-friendly bamboo fabric, moisture-wicking sports-performance mesh and a patented memory foam "V - Strap" with Velcro closure to ensure a snug fit that won't chafe or slip, allowing consumers to go green and stay cool and comfortable while they're working up a sweat."
