Abstract
A hydrogen operated gun for shooting projectiles such as a paint pellet. Hydrogen gas is supplied to a combustion chamber and is combusted by a trigger controlled piezo igniter. The hydrogen may be supplied by a hydrogen generator or by a hydrogen storage container located in the gun housing. Suitable valve mechanisms are provided to control the flow of hydrogen to the combustion chamber and the expelling of exhaust gases from the combustion chamber.
