Going back to the title of this post...Where to start? The disturbing thing is having to guard your stuff from theft! It would really suck to get all your stuff setup just to have it stolen. So I guess you would want to "travel light". It is hard to think of things you could "have" that might not be stolen. You asked about the DC motor I suggested and it made me think. I don't know. I don't know what size of motor would work for you or even if it would work or where you would get one. It is easy to throw out ideas when you are so far removed from someone's life. But I do know that there are a lot of smart guys on this site. If it is electrical they can help with circuits, rectifiers, filters, charging systems etc. And the best thing is they will, as long as things stay civil (place emote here).
I recently finished a certificate program in green technology. I think what hit home the most is how far we have yet to go in alternative energy production and battery technology. Also how far we have come. The reason I mentioned super-capacitors earlier was that they charge fast. So IF you had one maybe it could be charged at a library or somewhere and then used to charge some rechargeable batteries. They do have a low energy density, so you would have to charge like five. You see right now the concept is sound, just not very practical or applicable, but I did not think about that before I posted. Here we are again at square one.
Speaking of alternative energies, I thought this one was cool
