I'd like to see the benefit of each pan type analysed. If the fins are on the sides of the pan, then I can see there being little benefit on a frying pan. I'm sort of disappointed this is patented and only available on a saucepan costing £60+. It's the type of invention that would specifically benefit poorer house holds. As an 'evolution' of this, what would the impact of a cpu heat sink 'vortex' base have on the efficiency of a pan. Go crazy and have a double skinned pan (attached by many internal fins), then vent the hot air up through the gap between the pans via the 'vortex'. Now I know cleaning this could be an issue...but I'm assuming you would capture quite a high amount of the heat from the burning gas.
