Ive not seen you for a wee while as well, but im living in Stirling now and no doubt will see you in a wee while. All the best ma man.......Swiggi...ps can you live any further out in the sticks!!!!!!! i dont recall you bringing the banter btw.
the noise is the resultant not the catalyst therefore it doesnt use energy.
if the noise could be used as a fuel and you werent, then that would then be a waste.
if you bottle the noise and sell it then youd be driving a ferrari not a scoob!!!
