Author here, I just had to get some thoughts out and complain how bad these portable air conditioners are.<p>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.<p>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.<p>Dr. Verleger apparently was one of the key players in created the oil futures markets, so he probably knows a thing about this space.<p>[1] <a href="https://www.macrovoices.com/983-macrovoices-276-philip-verleger-energy-economics-and-inflation" rel="nofollow">https://www.macrovoices.com/983-macrovoices-276-philip-verle...</a>
