Generators used for backup-power have a problem in that they are frequently extremely noisy. There are some quiet ones with a lot of padding in the cabinet however there is a limit to how much this can quiet the engine driving the generator.

This idea is for an ultra-quiet engine that could be used to drive generators in settings such as dense residential areas with intermittent electricity supply.

The design is:

	- A boiler heated by gas burning, driving a steam engine
	- Slowly rotating steam engine
	- Steam output captured and recycled to prevent the need for on-going water supply, 
		and to prevent outputting steam into the surrounding area.
	- The steam engine driving a standard generator

	- The entire process optimised for minimumal possible noise generation
