Sounds like it is time for a good 'ld fashion science experiment. Who can test this? I am thinking for the baseline, time how long it takes to heat 1 gallon of water to boil on the blaster and one qt of water to boil on one burner on a stove. Then do it again with all five burners going. Time it using a T then using a tree and see if the times change. Bonus points if you light up your lantern on the tree!
I have a 4 burner partner, no blaster, tree or T, but I think I can get a hold of at least a blaster. if someone wants to loan me a T and tree for a few days I'll be happy to document.
