Is the computation heavy ?

OP! Thanks!!

I think @Lopess wants to do that, and I am committed to helping him make the Pull Request for it.  

We have a PM chat going, but for everyone else reading this, yes, you can do this:   Make sure to update all of the refs (references) to the files. So, if another tech file refs that moved file as a prerequisite, you have to update that line in that tech file. Same if you have any pairs, etc.

this looks great,we should add it to the main game!
