Yes take the bush 'off the grid" using CWE generator-hot water systems is a good idea.
However CWE for this to happen needs their machine to run using LPG in gas cylinders.
Whilst Australia has a large market - with many interested, until CWE generator-boiler runs on LPG will not happen - unless the NGN (National Gas Network) reaches the bush - likely at higher cost than the NBN !
