Go for it, David.  (If you have plenty of solar power, you could always distill your own alcohol.  Stills are readily available in NZ.)

The best system I ever used was to have a little pump led directly into a 20l container, with a filter leading up to the pump.  Just pump what you need directly into a lamp, or into a jug for filling the cooker.  A bowl to catch spills is good, too.

I've got a Broadwater gas stove with cast stainless burners.  It is 20 years old, and has never needed any replacement parts.  If I had grandchildren they could still be using it in their old age.  Indestructible, and it burns clean and hot.  Though refilling bottles can be a challenge in remote Pacific islands, especially French ones.  Alcohol stoves are also clean and easy to use, though they don't burn as hot, and the fuel is still prohibitively expensive in many places, even big cities like Suva, capital of Fiji.  I agree that kero can be messy and finicky unless the fuel is spotlessly clean, which is also becoming an issue in third world countries.  Boat stoves for long distance cruising have become a vexed issue, but then, come to think of it, so has long-distance cruising, with visa requirements, advance notification regulations, excessive admin fees for clearing into places like Australia etc.  There is no perfect commercial stove but perhaps a genius like David Tyler can invent an efficient alcohol one and we can fit a large, separate storage tank, so we can stock up with alcohol in places where the costs are reasonable.

That could well be so.  It wasn't something that ever occurred to me.

On the other hand, I was less lucky with the burner in Johanna’s Taylor heater. That one also had an Optimus burner, but not of the same model as those in the Optimus 155 stove, so regular attention was needed.  Frankly, that burner could be a real pain.

One of the things that you learn, when you cook with kerosene, is that you are dealing with something that has personality.  Nearly always there is a 'good' and a 'not so good' burner and you find yourself lighting the good one first and using it for preference.  Then, one day when you have two burners going, you discover that they have swopped roles for no apparent reason and start using the other one for preference until it happens again.  It all adds variety to life.
