Neat device.  I take it that one advantage to using a catalyst instead
of flame combustion is that you can use lower temperatures, and at
lower temperatures, there are fewer reactions of atmospheric N2 and O2
producing NOx?

The device seems to use a precious metal, platinum, for a catalyst.
Perhaps suppose it is a greater problem that the metal is hard to come
by than expensive, if the amounts are very small.  Is it possible to use
less expensive catalysts to bring the cost down?  For example, it's my
understanding that mild steel catalyzes CO combustion.
