Hi Jamie Please take a look at this site. www.fieldlines.com/There are a lot of knowledgeable and helpful people there, just like here. The range of topics covered is much wider. You might find some of them helpful. Pete |

One of the most important things to have in a disaster scenario is potable water. A small biomass fueled furnace like a rocket heater or a small updraft gasifier furnace can be used to pasteurize water. Add a sediment filter and a charcoal filter to the mix, and such a system can generate good quality processed water at a high rate. In particular, it is possible to use heat regeneration to increase the efficiency of this process many fold. When water is heated for pasteurization, there is no need to maintain the water at an elevated temperature for long. It's possible to use the heated water to preheat the unpasteurized water before it moves into the heater. A remarkably compact copper heat exchanger in a counter flow (also called "contra" flow) configuration can preheat the incoming water very efficiently to decrease biomass fuel consumption many fold for the same mass of water processed. A pump can be devised to send water through the system at a controlled rate, but it's also possible to send water to an elevated tank with a hand pump to allow for gravity to do this work. To give you an idea of what's possible, an efficient system can pasteurize and filter 100 gallons of water while consuming on the order of 5 pounds of dry wood fuel by using heat regeneration (and this is a fairly conservative figure). Without this heat regeneration the dry wood fuel consumption would be well over 20 pounds. Awesome. Water is very much in need...even with all the donations of water bottles coming to every disaster. When we were down south on top of the mountain - there was little water for everyone and it had to be conserved. Because of the nature of the mountain - where not even the red cross would go up there...water was in demand. This is an excellent way to get people healthy water...using rocket technology. Thanks so much for adding that. It was something I'd not even looked into yet. You're awesome  |

I feel like a child in a candy store LOL |

buenijo,
important stuff, it deserves it's own thread; I'd encourage you to discuss the concept of water purification more if you are willing

He discussed more in depth biomass gassification processes on Green Leaks (see my signature) - and I cannot wait till he posts more. These are things I only dreamed about before I met him. I didn't realize that it could actually be put forth into manifestation. I consider myself one lucky person to know you both...so thank you very much...for that. |

I've dabbled with gasification a little.
The thing I love about it.........It's carbon negative!! Strange as it might sound, it's actually pulling carbon out of the air!!
Is there anything specifically you would want to know?
