Very interseting. I have also been looking at the lithium sulfur batteries with interset. It will probably take forever for them to come out, but who knows. Less weight will be great for foamies. Safer stuff would be cool to, no need to worry about short circuits

. Small glow engines will definatley become rare if some new battery tech comes oout. If the price for large batteries comes down, it may also mean less gas powerplants in giant scale. But whatever the battery technolgy is, it still won't sound right

, so glow will never die.
I heard that these will have a nominal voltage of 2.1 volts..... GRRRRRRRRRR.......... all that means is all new electronics.
