The work I was doing on Mauna Kea was related to air conditioning. Keeping the "mirrors" on the telescope the same temp as the outside air when the dome was opened. And making sure the temps were stable across the surface of the mirror to prevent warping.
I used to "hang out" in the physics lab at Georgetown Univeristy to "soak up" whatever thermal dynamics education I could get. I find it quite fascinating.
I REMAIN skeptical of the long term benefits to metal using this process. Cost/benefit analysis has not yet been "proven" to my satisfaction.

EDIT: I came to Hawaii because it was WARM. And then they send me to coldest freeking place within 3000 miles.
