Purely "becos I could" I bought a wee adapter thingie that lets you connect a stove to the kind of gas cylinders you use in a weed burner and can buy for a Â£pound.
ASDA had said gas cylinders on sale so bought and connected gas cylinder to stove.
Gas Cylinder vertical and stove roars away fine.
Gas Cylinder horizontal and lots of large yellow flames --- !!
My pal Dougie K swears that these cylinders can be used laid flat.
Anybody got practical experience ??
