Solid-Liquid-Gas-Plasma: The fourth state of matter, essentially a charged/ionized gas that in semiconductors can be used to remove (etch) or deposit a film on silicon wafers.
Note this unique entry and possible future tech job...in trash:
There is, in fact, value in trash—if you can unlock it. That’s what this facility in northern Oregon is designed to do. Run by a startup called S4 Energy Solutions, it’s the first commercial plant in the US to use plasma gasification to convert municipal household garbage into gas products like hydrogen and carbon monoxide, which can in turn be burned as fuel or sold to industry for other applications. (Hydrogen, for example, is used to make ammonia and fertilizers.)
Here’s how it works: The household waste delivered into this hangar will get shredded, then travel via conveyer to the top of a large tank. From there it falls into a furnace that’s heated to 1,500 degrees Fahrenheit and mixes with oxygen and steam. The resulting chemical reaction vaporizes 75 to 85 percent of the waste, transforming it into a blend of gases known as syngas (so called because they can be used to create synthetic natural gas). The syngas is piped out of the system and segregated. The remaining substances, still chemically intact, descend into a second vessel that’s roughly the size of a Volkswagen Beetle.
"Turning garbage into gas": I know most teen boys can do that with a bag of chips (couldn't resist).
