Those gel cookers are really only a tin containing ethanol in a gelled form. The equivalent thing can be bought from food wholesalers cheaply. Also ebay but may be dearer.
They are also used to keep hotplates hot for outdoors caterers. They are very efficient, burn v.hot with no real smell or any smoke. To turn off, just drop the lid back in place. ideal for covert emergency cooking. They are minimal in their bulk. basically you are carrying a can of gel which is the stove in itself. I have a few of these & they do not go off or leak easily! The Tommy cooker was essentially the same thing in the 2ndWW. " empty tins of these, stacked up and with suitable holes perforated in the sides and the main aperture through the middle, will seat a meths burner inside quite nicely and it makes a simple expedient cooker once the gel has run out. The tins also make excellent water tight containers after use & before stove modification.
