Author here, I just had to get some thoughts out and complain how bad these portable air conditioners are.
I just don't understand why the appliances space attracts so little innovation or startups. Even though they are at least 400€ a piece and could generate lots of revenue on mass.
On Friday I listened to the newest Macrovoices episode with Philip Verleger [1] where they argued that America has far too few engineering students to even create a green energy revolution in America. The expertise was transferred primarily to software engineering jobs.
Dr. Verleger apparently was one of the key players in created the oil futures markets, so he probably knows a thing about this space.
