wow clever thought there...
If there is a low oxigen environment then all the oxidising that causes the impurities in metal would occur less... so wed need less energy to extract
the metals from their ores.
But what people seem to be forgetting is our first real invention of fire. I thought currently we beleived that fire was one of the first steps to our
technological progress... so without fire we wouldnt have started all of it.
Could metals be extracted from ores using pressure? Pressure generates heat, so enough pressure could generate enough heat to smelt ore?
If the alien environment has little oxygen because of weak gravity that is incapable of keeping it all trapped inside the atmosphere... then it takes
a lot less energy to get off the planet. If the gravity is weaker maybe you could build spaceships out of stone.
also what if there was a civilization non dependant on metals? Why do we use metals? Because we can melt them and make molds to cast them into any
shape we want. Also because they dont break easy. But circuits and things we need to conduct electricity dont necessarily have to be made from metal?
They could be any other sort of conductor, surely, most things are conductors.
HA! what if their spaceships were made of wood
, all it would take is a low gravity planet
