Thanks, I found this on the internet. Do you think it would work? An array of several convection tubes are positioned in a series configuration to provide the equivalent of a very tall convection current generating tower, the pressure and fluid flow of the array thereby becoming capable...

Hi everyone, I was wondering if it might be possible to drive the spit on my barbeque using a thermo cyphon in a closed water system... The idea being to have a standard 22mm domestic copper pipe running through the bbq fire. Both ends of the pipe would be connected to a small water tank...

Thanks for that Steve

Hi everyone, Some great reading there! I have always been amazed how a jumbo jet can get tanks landrovers and men into the air because the wings look tiny compared to the hold. There have been some interesting points here on how lift is acieved; but all that said how is it possible for...

Thanks DeShark. Im trying to understand how the Stirling hot air engine works and wondering if i could apply the principle to a rotary motion for my project After what you have said i feel a little more confident. Thanks, Steve

Thanks everyone, I didn't believe that air would burn. If it did and someone was to put a perverbial match to it; i think we would all be in big trouble! OK, so if for example air is compressed quickly in a closed system (with no leaks); would the fact that the air gets warm and expands...

Hi every one, When I compress air in a simple bicycle pump (with the outlet sealed) the handle or piston bounces back when i let it go. The energy released by the compressed air inside the pump seems to be less than the energy required to compress it. Am I right in my observation...

Thanks Russ - i think i get it now

Hi Brewnog, thanks for your reply. Ok, when you say zero force; do you mean that once the flywheels were at speed in a frictionless environment then all driving force could be removed and they would not start to slow down? - perpetual motion? Thanks

Hi Russ, thanks for your reply. Ok, let's say I am using "X" amount of force to maintain a flywheel 300mm x 25mm with a weight of 10lbs spinning at 100 rpm. Lets say we had another flywheel half the size and half the weight. To maintain it spinning at 200 rpm would require a certain...

Hello everyone, First of all may i say i am a layman to physics. Unfortunately, i have difficulty with maths. However, my question is this... Supposing i wish to rotate a car wheel (by hand) with the brake engaged upon it; but am not quite strong enough to turn it. Supposing i were...
