Is it getting hot in here or is it just me?

What does welding, power, semi-conductors and all of this other electrical mumbo jumbo have in common? It gets hot. Very hot.

So, what to do with all this heat? Well you could make a sauna or you could dissipate it. TO do this you need heat sinks which are made out of aluminum.

Wait a second isn`t transmission wire also made out of aluminum?

Yes, yes it is

Isn`t aluminum bus used as a substitute for copper?

Yes probably... why not I am saying yes to a lot of things.

So, if we are in such an economic boom who is getting all of this money? Or should I say who is making all of this aluminum and where is it coming from?

There is aluminum extrusion which is how most heat sinks are made. So, that is a good start. There is also milling and machining. Who makes the precision machines that can make these heat sinks?

People should be climbing over themselves to get these machines right?

Anyway I completed section 1 of the course time to start learning some math. Bleh
