Could they use this to carry gear that they don't want to turn intangible as part of their 20lb limit?
There is a disclaimer:
- The intangible person can not touch, pick up or carry anything
..
Just as the intangible character can not pick up or touch any object or person, he can not engage in combat.
However it's unclear whether or not person/character refers to objects manipulated using psi.
Unlike astral projection there's no text I can see prohibiting using these powers to affect the tangible world...
"Machines do not function while intangible" would prevent a Psi-Ghost from using a radio he's turned intangible, but could he operate that radio using TK if he DIDN'T turn it intangible? He can "speak and hear as normal" after all so it should pick up his sound as if another char was operating that radio.
Also a good Q for HU where you can mix psi/super for mutants.
