Wow - I hit the motherlode of info on this subject!
Berry had it right: the main reason for me looking into this
technology is to save weight. You guys in ships that can load enough
water to turn any desert into a green garden of Eden have no idea how
difficult it is to stay under a MTOW of 667#. Reducing the weight of
the battery while maintaining the capacity is a consideration and yes
- I am shedding pounds through diet and exercise, too! ;-)
