    very cool. Although, there's a wide gap between the lab bench and the real world. I think that's why companies like Tesla are taking a more conservative approach.

    Thank you for the link.

    A few first observations:

    *Out of Carnegie-Mellon.
    *They have Kleiner Perkins backing them.
    *From their downloadable presentation, it could be suitable for use in our remote AK village, other than that, very unfortunately but not surprisingly, the product is good down to a T of only -5ºC/+23ºF. Such a limit can be made acceptable throughout much of the lower-48, but would be unacceptable for us. The AGM Pb-Ca battery bank we presently use can withstand -40º temps for indefinite periods of time; typical storage temps reached are sustained at -25ºC/-10ºF.
