Rocket Stove -- version 2

2nd attempt at a "rocket stove". It is a work in progress. I already have an idea or two for a 3rd version, but I might not work on it for a little while. This version is different from v1 in the following ways: 1. Grill design is different 2. Grill is not painted 3. Grill is hinged 4. Feed tube is a 45 degree angle 5. Removable legs and tray that store in the stack 6. Another interior chamber to enable "gasification" or secondary burning toward the top of the stack. I don't get a blue flame, but I do get some secondary burning when the fire is burning heavy and high.
