Question: when you are making something what do you look out for?

anon answered on 13 Nov 2018:

I don’t make things really – I am trying to look at how things move inside a machine. If I can understand how things are moving in it, I can try to change the design or how it works to make it use less energy.

I need to make sure that the ways that I try to make it use less energy could actually be used and wouldn’t lead to any problems like having to buy a lot of expensive parts or reducing the lifetime of the machine parts.
