Lanny-These battered people are not going to cross cut construction timber for a batch-fueled stove, they need a stick burner. They need a stick burner that will burn damp fuel and large sticks, while maintaining a small, hot, clean burning fire. What do you think?-Lanny From: Crispin Pemberton-Pigott To: 'Discussion of biomass cooking stoves' Sent: Monday, November 11, 2013 3:31 PM Subject: Re: [Stoves] In search for a stove model for the disasterin the Philippines Dear All Thanks to Erin for that list - very helpful. Priante UTami, who is at YDD in Indonesia and how is a subscriber on this list has a lot of info on SODIS. I am wondering if there is some web-based material from YDD. After a big storm there is always a lot of pretty dry construction timber around, with rain on it. Efficiency is not a big issue because there is so much, but getting it made quickly is. Don't forget the Peko Pe which is easy to make and can to a certain extent be refuelled easily. I believe there are some drawings on line (if someone still has electricity). Regards Crispin The Midge is also a good gasifier made with simple tools, and can be made out of scavanged cans. It's not overly safe but it's a good temporary technology http://stoves.bioenergylists.org/stovesdoc/midge/THE_COMPLETE_MIDGE.pdf Japanese style cone kilns for biochar are also quick to assemble, and can be used with tree branches, vines and other misc sources of wood. It helps to have dry material, but this style of biochar maker is more tolerant of wet material than the TLUD oven designs: http://terrapreta.bioenergylists.org/Wilson-Cone-Kiln Dr Reddy's Good Stove designs are also quick to assemble from cans and other material that you may/may not have easy access to http://www.goodstove.com/ There's also the SODIS method for pasteurizing drinking water. If you have 6 hours of sunlight, you can use a simple fabric filter to get water clear enough and use a plastic bottle and some reflective metal to pasteurize it: http://www.sodis.ch/methode/anwendung/index_EN Keep in mind that the pasteurization temperature of water is lower than the boiling temperature. If the initial water is clean enough, a lot of fuel can be saved just by bringing it up to the right temperature. Here's a link to a chart for the temps at which most common pathogens can be killed: http://solarcooking.wikia.com/wiki/Water_pasteurization
