Inherent Safety of Common-Duct vs Pure Hydrogen Oxyhydrogen Cutting Systems

Mofos tellin me that common duct hydrogen for oxyhydrogen cutting is less safe than pure hydrogen oxyhydrogen cutting.

I would not accept that without careful systems analysis for one versus the other, and my suspicion is that the common duct hydrogen route can be made as safe or safer than the industry cutting standard - while retaining the cost advantage. This could potentially put the superior oxyhydrogen cutting route on the map as a practical - not a fringe - oxyfuel cutting option.

How much does a 1000 L/hr common duct hydrogen generator cost compared to a 1000 L/hr pure hydrogen generator? The common duct version is trivial - just plates and current.

So why would the common duct win? You can easily make throwaway cells that cost a dollar to replace. Engineer it to happen rarely, such that economically, it's a strong win, and in the worst case explosion, it fails safely without endangering people.
