There's probably a way of getting small amounts of power, useful for some monitoring or similar activity. Think wearable technologies, or "energy harvesting" (google it) - there's all sorts of individual piezo based or magnet/coil based solutions out there, to make lights flash, or allow data gathering.
I don't think it will gather enough to feed usefully into the grid, but it might to make art or some other local off grid thing.
