  Changing from heterogenous to homogenous HP decomposition is not a small
step.

  Could you give an idea of the mixed monoprop composition intended? Are we
still talking 50 % H2O2?

  In which case you'd probably equally use glowplugs to ignite the alcohol
in the approx. only 200°F decomposition products.
  Of which a large part initially 'll consist of oxygen and the rest of
*wet* steam. Have you been able to ignite such so far?
