    Thanks for the replys.
    Yeah I think I’ll give it a go. Grid power is too far away and I have no desire to play their game anyway. The creek is low in the valley so wind is not regular and gusting. A ram pump will work for over 6 months of the year but for the rest solar is abundant cause when te creeks not flowing well the sun is out in force. I’ve got a few cheap ($20) 12v diaphram pump that can pump up to 1mpa in small volumes 4l/m which I want to set up for the water supply on the top of the ridge at least 100m elevation above the creek and use 3 of them to get the water up that high. Then I’ll use the same pipe to run water back down through a home made turbine on a car alternator. Try this out as a test run and if it has potential put some bigger pumps with bigger solar panels and more storage up high. I don’t mind even > 50% loss if I can avoid the expensive and consumable batteries which I’m replacing. I’m thinking I might need a small deep cycle as a power buffer and some voltage switch to start the water flow and alternator when the voltage of that battery drops low. Enjoy.

    Hey Carlos. It’s Paul here (sprout man at Airlie markets) I’ve just joined as well. Saw the Whitsunday reference and had to check you out.
