Intersting site with some good information. It's too bad he seems to have a bias against what he refers to as the 'fabled' Pepsi can stoves...he doesn't seem to like the 'American' way of hiking either.

In his own 5 day chart, the Hexamine and Alcohol stoves are overall the two lightest options but in his conclusion he claims the cannister stove is the lightest over 5 days...I don't get that. He also makes a lot of assumptions...he uses the word assume or assuming, etc. at least 12 times hehehe. I'd rather see experimental proof than 'based on years of experience'. But I can understand how hard that would be. My personal reviews on this site are based on experience too so I guess I can't fault him too much.
He does make good points about the 'dead weight' of the empty cannisters however. This is a popular myth. I don't mind the weight so much as the shape makes it harder to pack in my backpack compared to the nice slender Trangia bottle
