People who do not have metallic mines miss them to the point of madness.
Between copper mines and iron mines, he misses iron mines more.
The reason is that iron has a wider range of uses.
Is it suitable to make machinery out of bronze?
It should be possible.
At least they can be used to make clocks and watches.
So is it feasible to make guns and steam engines?
Unknown.
His thought is that it should be feasible, but the performance might not be very good.
Why are the machines on Blue Planet all made of steel and not bronze? Is it because bronze's performance isn't good enough?
His own speculation is that copper is a rare metal, more expensive than all alloy steels, so everyone uses steel to make machines.
He tends to believe that bronze can be used as a mechanical material.
Although copper is a rare metal on Blue Planet,
there are only four thousand people here. As long as they can find a copper mine, it will be enough.
Too much thinking can cause fatigue.
