    Hi Plasma,

    It certainly clears one aspect of the design up, but also leads to a few more questions.

    I'm wondering if the design is not as (theoretically) efficient as a drycell using similar...

    Sure looks like a pretty robust design. Not sure how it's assembled though. Would need to know at least that before I consider one of these. I don't think I'm on my own on this.
