also i have read about people making pop can stoves but using redbull type cans they would easily fit inside
right i done a quick test using milton hand gel filled the well about 3/4 full and put a mug of water one (inch from the top of the crusader cup) i never used a lid which would improve things. Basically boil time was around 9 mins and the gel burnt out around 14 mins. Also of note mine is the webtex kit which i think is a direct copy of the crusader one hand gel is cheaper than the green heat as its often on offer in super markets and lights much easier and like you said has the added advantage of being used as a hand or wound steriliser :-D
Not all hand gels burn as well as others, the strength varies a lot.
If you are going to use a gel, this works better than most

You don't need to take the whole can, you can scoop some into a smaller container.
Nice, with an indicator to tell you that the flame went out:wow1:
