Thanks Eion, for the very encouraging comments. My intention was to visually demonstrate the physics behind the Flow Effect. Glad you have gained knowledge and insight from the posting.
Great Demonstration.., It gets the message across quite well I think. There will always be those who are only good at sitting on their butt and criticizing others; they are the ones who have never done anything constructive in their life and probably never will for fear that they might fail or make a mistake.

Thermosiphon flow is powered in part by gravity(density changes interacting with gravity cause movement). Because of this the areas where energy is being added to cause the density change need to be as vertical as possible to cause movement. Up on the hot side, down on the cool. Your rig here is mostly horizontal so very little flow...
Because this is made in a poor 3rd World country rich only in Sunlight as the only free natural resources. Anyway, this is for educational purposes only; not to advertise and sell something!
