Nice, I&#x27;ve always imagined I would build an windmill of some sort. Having seen the hydro-rock energy storage device I could imagine an interesting combination there, pumping water to lift the rock, using the water pressure from the rock to generate hydro power.<p>It has also always disappointed me that turbines in California were so constrained by wind speeds, between X and Y MPH they could turn, under or over those numbers and they feather their blades and stop. I&#x27;d like to experiement with turbines that could work in any wind that didn&#x27;t physically cause them to fall down.
