No. The butane will vaporize below the boiling point, just as water vaporizes below 100°C.
The advantage of the "one way"/piercable canisters is that they are way cheaper (up to four times with respect to price per mass of gas according to German Wikipedia). Also they are "good enough" f...
In UK I have only ever used the simple type. The female part of the screw thread is on the shroud which clamps around the gas cartridge, and the appliance screws into that, instead of the canister....
It looks like it will depend on the beach, some beaches have restrictions on where you can launch, some don't and some do not allow kayaks or paddles sports. It would probably be easiest to ask th...
You seem to have worked out many of the important principles that are needed for a system like this. The most authoritative source that I know of is Petzl's articles on top-rope soloing. The do...
No. There is a safety system in the newer C206 canisters that should prevent you from emptying a pierced can, unintentionally or not. It remains to be found if this works at low temperature and pre...
With pictures posted, it looks like it is the African tulip tree (Spathodea campanulata). The decisive features were the long pod with the pores. Similar (but not as strongly heart-shaped) seeds ar...
I've used foam mattress toppers before. So they can absolutely work well but there's a few things to keep in mind. Thickness - 4" is OK and would probably be great for a back sleeper on grass. Ho...
It looks like the answer is to clean them out at least once a year, once the breeding season is over and before winter, which would be around the end of August in the northern hemisphere (or the en...
It's a normal occurrence in the spring for fledglings to leave the nest. Wildlife rehab centers also commonly get calls regarding people finding baby birds in the spring. Unlike nestlings (whi...
If you look for the manufacturer's promises for these "passive" boxes (there is absolutely no cooling, just the attempt to keep the cool in - called isolation), they usually state something around...
A dark coloured water bottle strapped on top of your pack would absorb quite a lot of solar heat on a sunny day. Getting the snow in would be easier with a wide neck, like a bike bottle or Nalgene....
I will not comment on the general feasibility of your plan. However, I did a little research about the specific heat of various materials, and the results are actually pretty interesting. We are ...
I'm assuming the amount of food you want to take and your coolbox size is fixed, so the question you're asking is really whether you should fill every remaining gap with ice, or whether you should ...
tl;dr: No. Any theoretical advantage of one rifling profile over another is lost in execution. Since this is a question of practice, not theory, I appeal here to the experience of authorities in ...
My viewpoint: If it is unlikely to be seen before natural processes take care of it then disposal in the wilderness isn't unreasonable. Thus, below timberline, outside Jasper National Park, walki...
It's a very good question. I found an article that has some suggestions: Finally, it is important to consider your visibility on radar and at night. The best way to ensure that you are seen on...
The problem with food waste at that elevation is that there is very little soil to bury things and that decomposition happens much slower at those altitudes. Sometimes there are still marmots/pika...
I have been kayaking around Corsica, Denmark etc for longer periods in one man boats. We brought everything with us except food for the entire period. We had some spare food and a one or two day su...
There's no specific rule for how much cargo a single kayak can take, but there is a general rule that says a two man kayak of a given model has the same cargo capacity as a one man kayak of the sam...
Posting this partial answer in the hope of soliciting comments: Electronics suppliers like digikey sell UV LED’s in various wavelengths, and various devices such as photovoltaics or photoresistors...
From my experience, NO. My only experience using a few different Gri-Gri devices was during my beginners course last year. I have however used figure 8 belay devices for years at scouting and that...
Note: I'm not from the UK, but a quick search of the laws relating to poaching is pretty easy. Note: THERE ARE MANY ANIMALS IT IS ABSOLUTELY FORBIDDEN TO HUNT/SHOOT (think large large fines and ja...
As close together as you want! Most climbing gyms will set up 5m (ish) lines which is a pretty good distance for beginners. In general you probably don't want to go much less than 3m. Keep it nice ...
The gun laws in UK are extremely tight. A firearm at your house must be licensed and kept in a locked cabinet. Even being in possession of a firearm in a public place in the UK without a lawful rea...
