Talk:Gyrocar

Possible copyright violation

I just noticed that some of the text in the third paragraph is taken word for word from:

http://www.douglas-self.com/MUSEUM/TRANSPORT/gyrocars/gyrocar.htm#gyrob, which is:

"The Brennan gyrocar worked on the same basic principle as the gyro-monorail. Two contra-rotating gyros were housed under the front seats, spun in a horizontal plane at 3500rpm by 24V electric motors powered from standard car batteries. This was the greatest speed obtainable with the electric motors available, and meant that each rotor had to weigh 200lb to generate sufficient forces. Precession was in the vertical fore-aft plane."

1. wikipedia page from 2006 has already substring "housed under the front seats, spun in a hori".

I think a reference in HG Wells "War in the Air" (1907) chapter 3 " Then heavy motor-cars began to run about on only two wheels, one behind the other…….. All this gyroscopic…. development…." Predates the stated first mention. 92.17.231.180 (talk) 21:35, 29 June 2025 (UTC)
