Pump it full of seawater, and then run it back down the 90 meter cliff when you want to use energy.<br /><br />http://tinyurl.com/5rndh2l<br /><br />That's the kind of scheme that could *almost* convince me we could solve intermittent renewable energy.<br /><br />But I didn't hear what paper had verified it was cost effective?
