> You will always find the most efficient farm machinery to be the least human-like in its design principles [...] the combine harvester

Oh? I find my human-based process for separating grain to be of the very same principles as the combine. The specific mechanics aren't exactly the same. For example a combine has a fan, while I have lungs. But the principle — using airflow to aid in separation — is the same.

The sprayer is the only piece of equipment on my farm I can think of that employs a different principle to do the job as compared to how I would do the job by hand.
