What does the QT in qt-rtg stand for?

I like to believe it’s QT as in cutie cause it’s like a little rtg yk😂🤷‍♂️

Edit: after some debate I think the astroneer community has come to a common consensus that it’s “cutie” rtg allow me to provide further reason as to why this is the case while the qt-rtg is a quarter the power u can fit two of them in the space of 1 rtg therefore not a quarter the size therefore it’s “cutie” rtg case closed😂😂
