TW Power Convertion and the Rules

[Nightmaster]

That is a question that comes from one of my players regarding the creation of a TW power source for a power armor.

The question is: How can I create a TW power source that could run a power armor for 5 years of constinuous use?

He ask me how much PPE to construct, what spells and devide level and principally how much PPE to recharge the said power source to full power.

He also have a goal to construct a TW spaceship (after geting rifted to Center and seeing the ships there he got that idea) and for such thing he wish to know how to create that part.

I really dont know how to answer that question so I am asking you guys.

This is also a question that goes on my mind from time to time because I really dont know hos to determine for example how much PPE is stored into such TW power sources that are always a option in the construction rules for Robots that are presented in the SB1 for example and other vehicle creation rules around as well.
