Area was on TV-Coast the other night with Nicholas Crane. Might still be on iplayer. He raved about Sandwood Bay which is great, though I didn't camp there;not a,big fan for camping on sand it gets everywhere.
The Groove stove works very well, it takes about 6 minutes to heat up two cups of water using less than 20 ml alcohol. Your cook pot sits directly on the stove, so no pot stand is needed. Its good design means that, after it has cooled down, any unused fuel can be easily poured back out.
I recently camped six days in Belgium. With flight restrictions on stoves I decided to make my own stove over there. I did practice a couple of times before I left. Others have put explanatory videos on Youtube; reference Groove stove.
The stove, for use with alcohol, is made with a pair of scissors and small knife. It is easier to make than other pop can stoves I have made.
To make it only one can is required, which unfortunately can be found by the wayside in minutes. I used the smaller red bull type can, the larger can be used but I saw no advantage in the boil speed with a larger can. The larger can has too much flame spread for my MSR Titan kettle so heat was being wasted.
Briefly, using my thumb for making measurements, I cut off the bottom of the can a thumb width high. Cut a ring from the same can making it higher than the can bottom by adding the width of half a thumb nail. Then with the ring between two fingers use a knife, or similar, to press between two fingers to bend in a slight groove. Rotate the ring to make six equidistant grooves. The flames come up the grooves formed.
The ring is then fitted into the can bottom you cut earlier. The job is done. It takes about 10 minutes.
I spotted these modifications for flexible platypus drinks bottles -that is (1) drill enough small holes in a spare drinks bottle top to form a spray, not exactly a shower by useful to squirt on the feet/hands.
(2) Similarly drill out nearly all of the bottle top and place a womans make up pad, or piece of tight in the top. It should still screw on the bottle, this will give a useful pre filter to sieve out any floaties in the water.
