As a voter and a taxpayer, I’m waiting on some important concessions before I can support this. Were Trump, for example, hoisted in front of the arch by a crane and dropped from the top into an inflatable kiddie pool filled with cottage cheese, this could become an important and beautiful landmark for D.C.

You’re getting downvoted for pointing out that this technology, at optimal efficiency on Earth, generates about 1/100,000 the power of a solar panel. “Not very useful” is an understatement (it’s currently fucking useless). Even worse: the title saying “at night” implies a terrestrial usage and misdirects from this technology’s only potential useful application in the future once and if it becomes much better – namely on deep-space missions.
This research is interesting. I hope it yields something useful. Your comment is still 100% correct for the foreseeable future.
Edit: I was conflating the optimal efficiency of 1 W/m2 and the actual efficiency of 1/100,000 the solar panel. Sorry for introducing that confusion.
