[TheForge] oxygen-gasoline/diesel/kerosine

[Kyle Dwyer]

Hi Terry
I am a firefighter who is also on a Urban search and rescue team.
We have been using the The Petrogen system for a long time.
I think this system was initially designed for the rescue service, it is
cheap to run and easy to use and very efficient on big steel and the rescue
rigs don't have to transport pressurized flammable
gas. You can pressurize the gas once on scene of an incident.
The cost of the equipment is of course paid through the taxpayers.
Cheers.
