okiedo,

I am also of the belief energy storage is so very important to the future of life on earth. My reply to hardstop's post about the term "Holy Grail" (and how many times he says he's heard it referred to) was merely to acknowledge that regardless of what you or I think, there are many disbelievers or oblivious individuals that are immediately turned-off by anything referred to as "The Holy Grail". They view such things as "snake oil" in many cases. So, regardless of how important and significant "we" feel it deserves to be, others will be reminding us of past history and how many Holy Grails have come and gone. Let's hope this one sticks.
