Trinidad traditional transportation. This scene is quite typical of this Cuban town. The horse my be actually a little below the 1 HP. I would guess around 0.40 kW. (as per Francois, this 0.4 kW= 1 Mule!!)
The horses are equipped with diaper, which catches their excrement.
The town has less horse shit than in Toronto, where the police horses pollute without any regard for clean city and obviously without any punishment.
