In later experiments Steven E. Jones and Christopher McMillan
of Brigham Young University tested different bases for the
cooking pot used in the Solar Funnel, published on the web in
the article "Tests of the Solar Funnel and Bowl Cookers in 2001.
According to Jones, the rabbit-wire stand they tested has proven
to be much better than the wooden block detailed in this article.
"We found immediately that raising the vessel off the bottom
of the cooker using a rabbit-wire stand provided more rapid and
even heating than the wooden block used previously. Placing the
jar or pot on a wire stand allows as much reflected light onto
the cooking vessel as possible. This allows even the bottom of
the cooking container to absorb thermal energy that is reflected
off the lower portion of the funnel."

different sized cylinders, made of rabbit wire -- fencing
material for rabbits, made of crossed wires tacked together,
so to make a single sheet. A black pot is being lowered
into the cylinders, and will come to rest on a wire cross,
inside the cylinder, made from wires going from one side of
the cylinder to the other.]
