You are putting energy into the pavement when you walk pavegen tiles or not.
Yes; but you get almost all that energy back. The pavement is staying
within its elastic limit, and "bounces back" to its original shape --
i.e. it is not permanently deforming.
Energy is force times distance. The force is your body weight. The
distance is how far the surface you step on moves. When the distance is
tiny (like walking on pavement), the corresponding energy is also tiny.
For this concept to work, the surface you step on has to move a lot.
Then the force x distance produces to a more useful amount of work. But,
now you are always walking "uphill", because where your foot is now is
(say) 1" lower than where you are about to place your next foot. You're
always stepping up out of a hole.
