This is a repost, because WordPress ate the original when I tried to delete a test comment.

In a test last night, The SVEA 123R used 0.5 oz. (weight) of fuel to boil a quart of water in eight minutes.

Starting was balky and difficult though – warming by hand didn’t work, and I had to prime it twice with rubbing alcohol before it started. I need to test it more. There must be something wrong with my technique, or maybe rubbing alcohol doesn’t burn hot enough. An eyedropper of fuel technique might work better, or perhaps denatured instead of rubbing alcohol.
