Re: [Phys-l] E-M radiation pressure

Bernard,

PIRA makes no such claim.

Your quote, below, is a reference in the PIRA Demonstration Bibliography,
http://physicslearning.colorado.edu/Pira.asp, to Richard Sutton's classic,
1938 "Demonstration Experiments in Physics".

The entire text of Sutton's work is online and linked from the Bibliography;
by clicking the link included in this reference, you could have read his
entire (suspect) demo number H-165 here

Subject: [Phys-l] E-M radiation pressure

is sufficient for a hot object to repel smoke?

PIRA claims yes.  


4B50.62 	radiation and convection 	H-165 	Put a hot metal
object in a 
smoke filled projection cell and the smoke will be repelled by radiation 
pressure. Convection will cause an upward clearing.

bc, thinks not.
