I have been giving this some thought. If the grid is available, the only way off-grid power makes since is if it's almost free. One of my thoughts is to run my generator head with a steam engine which could burn, wood, waste oil, propane, whatever. If necessary, enough batteries would be needed to fill the gap when the mains get interrupted. There would be enough batteries to to keep the power up until the hydro-generator kicks in. The hydro source would be a tank on a tower, or a tank at the top of my hill with the turbine at the bottom. The tank would be pumped up when I have excess power. Hopefully there would be enough hydro to allow enough time to get the steam engine up to speed. Or maybe have the hydro turbine do double duty as a water and steam turbine. Anyway, this is some of what I think about when I do my morning thinking. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ Increase Visibility of Your 3D Game App & Earn a Chance To Win $500!
