I hear you loud and clear Kirk. On the one hand it is pretty cool to see so much interest in battery-based systems, on the other hand the level of misinformation being spread around is frightening and time-consuming to combat.
There is a Bill McKibbon article in the New Yorker this week where he unfortunately, loudly and clearly, repeats the Tesla marketing spiel. He reports from the CEO of Green Mountain Power - "Powell was excited by its low price: three thousand dollars, far below what analysts had predicted, and low enough that her company could immediately begin installing it for customers, especially those who wanted backup electricity in case a snow-storm disabled the grid." Here's a link the article: http://www.newyorker.com/magazine/2015/06/29/power-to-the-people The more I re-read this the angrier I get, and honestly it would be awesome to send a group co-signed letter to the New Yorker refuting this inanity and telling Bill M to do his homework. Send me an email off-list if anyone wants to follow-up.
