Quiet gas generators are generally powered by something very similar to solid rocket propellant. However they are generally designed not to maximize the energy available, but to produce volumes of cool gas.
One of the most common gas generators is the chemical oxygen type, however there are a variety of options available, you just have to take care when purchasing one of these machines as there are some cheaply made options available and these should be steered clear of. These generators are available for emergency, professional and recreational purposes.
Oxygen is essential to all living things on this planet, and it is for this reason that oxygen generators were designed. Clean air is an absolute necessity and gasoline powered generators are not the bet thing for the environment. They also cause pollution, just like the cars we drive, so a generator powered by oxygen is a little bit of a miracle really as it adds up to breathing cleaner air.
The best gas generator you could possibly purchase would be one that has a well known brand name. For example Brigs & Stratton who offer both gas and electric powered models. Gas generators are generally quite powerful and have a silencer or muffler which helps to keep noise levels low and avoid sparks.
One of the chief reasons for avoiding sparks when making use of a generator is because they are used for recreational purposes. This means for camping out in forests and such-like. They are able to bring some of the comforts of everyday life to even the most remote of areas. Not everyone who enjoys being in the great outdoors is able to withstand all its rigors. And while you think that camping should mean roughing it, others may not believe that this has to be so, and would like not to have to miss their favorite TV shows, or at least have electrically powered lights while still enjoying nature. Gas generators for recreational purposes are the most popular sellers and it is because of this that they are both flexible and feature rich.
