Talk:Tutorial/Automated Mining/@comment-5430595-20121112040107

While I much prefer flying redpower contraptions and Turtles to do my digging, and I usually stray away from buildcraft in general, the comment on the quarry does pique my interest.

How exactly was it found that a quarry is "about 100 times more costly... than mining by hand." I would very much like to see the math or at least a citation to attest the validity.

In one regard, it is incredibly costly... the first time. After the fifth rendition or so, I would think the benefits turn around. Once you have some power source (even if you're using up oil to fuel the thing), how is it costing you anything more than you would by mining with a pick. What other use for the fuels and oils would you have?
