dragonstar57 Posted July 12, 2013 Share Posted July 12, 2013 (edited) I heard recently that in many places much of a person’s time is spent collecting fire wood to heat water for the purpose of sterilization.I was wondering if a solar oven could be used instead of fire.I'm thinking of something like this.a plastic box with reflective surface with a reflective interior measuring 1Mx1Mx1m and a lid which would be propped open at a 45 degree angle (and is reflective) would this be an effective solar water purifier?

dragonstar57 Posted July 13, 2013 Author Share Posted July 13, 2013 (edited) I know about solar distlization. I was wondoring if a solar oven would be better for cleaning water of microbial contamination.woldn't it be more eficient to simply heat it to the point where it kills the microorganisms in the water?

iNow Posted July 13, 2013 Share Posted July 13, 2013 (edited) Yes, a solar oven could do it. It's all about how you focus the mirrors and what you use to heat the water. Edited July 13, 2013 by iNow Link to comment Share on other sites More sharing options...

John Cuthber Posted July 13, 2013 Share Posted July 13, 2013 good question. probably because we'd rather spend our money on beer and flat screen televisions Not to mention wars. On the other hand, our soft drinks industry might be helping in an unexpected way. http://en.wikipedia.org/wiki/Solar_water_disinfection Link to comment Share on other sites More sharing options...
Externet Posted July 14, 2013 Share Posted July 14, 2013 Recycle clear PET soda bottles onto fresnel lenses and you would be capable of boiling vast amounts of water, fast, cheap to distribute, by focusing several suns of energy onto a vessel. But try to buy a fresnel lens from a vendor, and your wallet will be wrung. Jump to time stamp 2:30----> Link to comment Share on other sites More sharing options...
EdEarl Posted July 14, 2013 Share Posted July 14, 2013 The low tech way is to make a parabolic basket from local materials and line it with all foil...cheap solar heating. But, some places do not get enough sun. For them filtering water may be best. Link to comment Share on other sites More sharing options...
