Fascinating Science: How a Crookes radiometer works
Published on Nov 3, 2014
A Crookes radiometer is driven by a thermal gas effect,
and not "light pressure" as often thought.
I demonstrate the radiometer in a vacuum chamber and explain its optimal running pressure. https://en.wikipedia.org/wiki/Crookes_radiometer_...
30 years ago 1990
i was on a snowy gletsjer mountain in kaprun / sell am see austria
there was a weather station on top 4km or 2500 meters high
i believe i have seen more or less something like this
on the wheater station
always stayed in my brain in the directory unsolved
Yesterday i was reorganising my brain
and plop, there it whas again
every now and then it comes floating into my mind
nowadays whe have internet and google
But what have i seen
was it realy something like this
i think there was even some crank connected to it
