The Kelly kettle

Tried out this gizmo today in the garden. It’s a small wood burning stove at the bottom with a tall tube like kettle above which the fire heats up the whole inner surface. Used twigs and pine cones to feed it. It worked surprisingly well for a cup of tea. Then stuck a fresh potato from the garden wrapped in tinfoil on the top with a grill and it cooked that in 20 mins. Lovely.
