资工

资 = 次 + 贝 : Zorro (z) has become a real capitalist (资). In front of the space station (Ø1) he locked a crab (贝) into a cube (次). Whenever he throws organic waste into the cube, the crab is so furious that it cuts the carbage to really small pieces and throws it out. Zorro then collects the cut garbage and sells it as organic fertilizer.

工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam.

Gitta Giraffe (gu) is working a shift in front of the engine ((e)ng1). Her job is to melt dinosaur bones (丨) so that they can be disposed off easily. To melt the bones, she is shorting a huge capacitor (二) with a steel beam (工) which consequently heats up to a bright glow. Using the glowing hot steel beam she can melt the dinosaur bone easily.
