Let's see...
- Ive got a bunch of small devices powered off USB battery banks that are solar rechargeable
- indoor and outdoor gardens, with sensors also powered by those little battery banks
- My kids do a bunch of sports throughout the year now, I bring my bike toolkit so I can help fixing bikes for the kids in their school that show up
- Sharing what we get from gardening with neighbors. Except potato. Potato is mine (seriously though, we go through them quick)
Nothing else I can think of off the top of my head
