We need to answer the following questions:

Can a nanite colony produce a net energy output by eating
organic material/earth crust?
What is the best upper bound on the time it would take to digest a
given large volume of the substance?

We do not require that the end product is diamond, just that the
nanites can extract net energy from the material. My preliminary
guess is "Yes" to the first question (both wood and earth crust), and
"A very short time." to the second (because the time should be largly
independent on the volume, since the nanites can multiply and divide
the labor)
