My horse carriage is very useful. The horse just feeds itself, if you leave him in a grass field. It rarely gets sick and last many years. The wheels are easily replaced from the store.
The other day I saw a crazy guy with a mechanical contraption that, according to the guy, moved by burning wood! The guy was demoing it at the town. He filled it with wood, and then had to start the fire. The crazy machine got so hot that nobody could get near it. The thing barely moved a few meters and then Kabooooom!! it exploded in a black cloud. What sane person may ever believe that one of these contraptions could be useful?
Am I right? Are you right? we don't know. Research is the only way to know.
