Brownian ratchet: put a vacuum on the side of the pawl, and have particles only hit the paddle. By putting a vacuum on the side of the pawl, the brownian ratchet now succeeds to work instead of failing.
1:12:00 Maximum efficiency of a solar cell by theory (single junction). Sad to see that there is a limit to this, once I watched a movie saying 80% but this is now science fiction. Makes sense to me, even electrocatalysts have a max efficiency by theory too, I have read. Multijunction is still better but...

18:01 I think it is Lennard Jones potential, not Vander Walls
I stand corrected there could be 80% as the movie said, 1:17:00 ish
If we assume that profs Gang Chen and Donald Sadoway are 2 football teams playing a match, the final result would be 0-20.
Who wins?
Someone knows a reference that says liquid transport is poorly understood, as he says?

7:50 we dont understand transport in liquids, very well, wow, that's deep
1:22:19 nice figure for PV cost by methods
He has not the slightest clue what he is teaching ;)
