Not
such a difficult concept when you remember setting fire to paper as
a kid
using a magnifying glass.
On combustion the residue is water if my O level Phys/Chem
memories
are correct.

Your memories of chenmistry are very badly flawed. Burning carbon
does not yield any water at all. It yields mainly CO2 under ideal
burning conditions. The CO2 is the ****** in the woodpile which we
are trying to get rid of.




I was trying to illustrate the power of the sun correctly harnessed.
I am aware that burning paper causes the same problems as burning other
fossil stuff -CO2 etc.
Its the burning of hyrogen that I hope would produce water alone.
