here's my bright idea for a portable water sterilizer.
i looked around and found nothing like this, and my thinking is that the intense sunlight at the focus needn't necessarily boil the water to kill the germs.
the gravity flow gets metered by the narrowness of the glass tube. (water reservoir prolly needs a vent.
)
whatcha think y'all?
