By popular request, I got my information on Hydrox from

Mixed Gas Diving
Tom Mount & Brett Gilliam
Watersport Books
ISBN 0-922769-41-9
Published 1993 by Watersport Publishing, Inc.

You could try getting this from Amazon.com: Mixed Gas Diving

The correct percentage at which hydrogen - oxygen mixtures become explosive is
4% O2.  This gives it a minimim operating depth of about 100 fsw.

As well as the travel gas (e.g. air) to reach 100fsw, if diving scuba, a
transition gas of, say Nitrox 4 is needed.  Otherwise while switching from the
travel gas to the Hydrox 4, the mixture in the diver's lungs would exceed 4%
O2, potentially leading to an explosion.

All told, it doesn't look useful for scuba applications.  In saturation diving,
if the habitat is at or below 100fsw with an appropriate gas, there would be no
need for a separate transition or travel gas.
