Mod that modifies personal armor.
First thing:
A small nerf, that is actually a buff. Your equipment grid is reduced by 1 point form 5×5 (25) to 4×6 (24) in modular and from 7×7 (49) to 6*8 (48) in power armor mk1. Hovewer, since most equpment is 2×2, you actually gain more space.

Power generation:
You get Personal Steam engine when you unlock modular armor. It generates 250KW by burning fuel source. Any fuel source.
Personal Solar was upgraded in 0.17, so I'm leaving that to WUBEs numbers. IMHO its still a bit underpowered.
Lategame tech is Personal Nuclear Reactor, consuming uranuim fuel cells it generates more energy (1MW vs 750kW) than fusion reactor occupying only 2×2 space.

Movement:
MK2 Exoskeleton has been added, its direct upgrade from MK1 in simmilar fashon as shields, roboports and battery. It adds 1 to movement speed, so 1 doubles it, 2 triples it etc...

Technology:
With addition of Personal Steam Engine, its no longer necessary to research Personal solar to get to most technologies, so the requirement has been removed.
Personal Nuclear Reactor requires Utility Science Packs.
