Physics news on Phys.org
www.howstuffworks.com , you can get good examples of commonly used technology that uses resistance to operate.
 
thanks a lot nenad .. .please advise me wid more links if u come across
thank you

I am following someone on Youtube who has built a rocket shaped (4 proprllers) drone for the world speed record ... He was having problems with internal heat from electical control gear and battery inside the sealed rocket (about 1kw waste heat) Speed is 500km/hr , I suggested a 4mm hole in the tip of the nose and 8mm hole at rear which should alow sufficient air cooling .. I said this will increase thrust because the air exiting is hotter .. a bit similar to a ram jet ... was I correct...
