I like the bit where author poses the question "how much energy do the lamps save?" and then chooses not to answer it and veers off
into some stats about CO2 emissions.

Not to be a dink, but an invention which creates light... only when the sun is out? Sounds a lot like the "window" or "skylight" to me. Reminds me of how NASA spent a ton of cash on a pen that worked in space while the Russians used pencils.
"Oh geesh, it sure is dark in this windowless room"
