[pct-l] Steri pen water purification

[kcristler]

bulk and trekker,
    I can't believe how tunnel visioned i am sometimes. I thought lithiums 
were rechargeable because my lithium camera battery is rechargeable. This is 
interesting. Lithiums appear to supercede alkalines in the throw away 
battery class. Hikers use lithiums to avoid the hassle of recharging NimH 
batteries, i guess. But rechargeables would be much cheaper in the long run, 
correct? One quibble. 1.2 V is not equivalent to 1.5 V. That is probably why 
lithiums last twice as long as NimH. Thanks for the beta. I needed it in my 
dulled state.
                    Kerry
