Contrary to what many people believe, it is not necessary to boil water to make it safe to drink. Also contrary to what many people believe, it is usually not necessary to distill water to make it safe to drink. Heating water to 65º C (149º F) will kill all germs, viruses, and parasites.3 This process is called pasteurization and its use for milk is well known though milk requires slightly different time temperature combinations.
* forgot to put the time needed. keep at 65C for 30 mins. also, water must be clear. brackish water wont work.
this is just another option. u may not always be able to boil water. with pasteurization i could filter canal water thru my t-shirt into a clear bottle, put the bottle in a closed up car sitting in the sun and less than an hour i have safe water(as far as biological stuff). no heat, fuel, or smoke.
