I just happened across this little gadget, and thought it noteworthy to post it up here.
A Solar Cell Charger with USB output. In other words, you've got nothing but a Sunny day and a Dead Q battery. Connect your Q to the Solar Charger and give it some time.

I'm hesitant, as I don't know what voltage my Q needs to recharge. Anyone?
