There must be a way you can generate electricity while you walk, something in the souls of your shoes that compresses and convert's your steps into voltage. Might not work in the winter months with all the snow you get.
Hmmmm! I think I just invented something while replying to your post:-)
The work you do for this platform is always appreciated and I'm not surprised you have little time left over for walking.
