Here is a link to a group of BPL members that took a trip together early this year.
There are a lot of photos of UL gear, but jump to the middle.
There is a "burn-out" contest to see who can boil some water the fastest using different stoves.
There is a prototyple of the BCB with photos of it in use, the underside of it and the top....should give you a good feel for how it is used.
Please note: the performance in the photos is more of a function of the user having trouble getting a fire started vs. the BCB itself.
