At least the line cone elevators will smell nice.

I have what I think is a lodge pole pine here dropping pine cones like snowflakes if you need a truckload or two.

What's a Line Cone?

You will have to update your cartoon regarding refrigerants. R134a is already out as an automotive refrigerant, replaced by the highly flammable R1234yf since 2013.

2,3,3,3-Tetrafluoropropene, HFO-1234yf, is a hydrofluoroolefin (HFO) with molecular formula CH2=CFCF3. Its primary application is as a refrigerant with low global warming potential (GWP).<a href="https://en.wikipedia.org/wiki/2,3,3,3-Tetrafluoropropene#cite_note-Sciance-1"><span>[</span>1<span>]</span></a><a href="https://en.wikipedia.org/wiki/2,3,3,3-Tetrafluoropropene#cite_note-CP2014-2"><span>[</span>2<span>]</span></a>

As a refrigerant, it is designated R-1234yf<a href="https://en.wikipedia.org/wiki/2,3,3,3-Tetrafluoropropene#cite_note-Sciance-1"><span>[</span>1<span>]</span></a> and marketed under the names Opteon YF by Chemours and as Solstice yf by Honeywell.<a href="https://en.wikipedia.org/wiki/2,3,3,3-Tetrafluoropropene#cite_note-Aspen-3"><span>[</span>3<span>]</span></a> R-1234yf is also a component of zeotropic refrigerant blend R-454B.

Unlike previous vehicular refrigerants, 2,3,3,3‑tetrafluoropropene is flammable; how much risk this poses is discussed below. One drawback is it breaks down into short-chain perfluorinated carboxylic acids (PFCAs), which are persistent organic pollutants.
