Interesting.
How about boiling the water after collection and the silver part in order to be extra sure? Or you think this is not necessary and the water will be very safe to drink?
I have read about killing germs with copper, don't know about silver. I wonder how effective both will be in keeping water free from germs.
Boiling the water can help to eliminate any parasites,germs and bacteria but the water may contain polluted particles like heavy metals and chemical substances which needs certain purification before making it completely safe to drink.
