Albert Einstein and the Flettner rotor
”Even after the successful test of the BUCKAU in 1925 Mankind was still to stupid to make use of the technology” even though it was right under his nose ..!” Albert Einstein Source: Albert Einstein paper on flettner rotor University of Jerusalem
”
Flettner’s rotor ship was praised by Dr. Albert Einstein as having great practical importance” Source The New York Times - December 30 1961
