[Stoves] ***SPAM*** Comment on ETHOS 21

[Ronal Larson]

List:

	I’ve been asked a few times why so little messaging these days on this list.  I was glad to be able to say that last night I had sent in a message on using a (possibly) cheap quarter barrel as a hood to help on health issues.  Anyone else able to expand on any stove topic?

	But this is to report after 4 of 5 days in ETHOS-2021 - that for COVID reasons is being conducted on a combination of ZOOM and a new-to-me program called “spatial.chat”. For organizers of on-line conferences like this one - this last app is worth investigating.  You have to use it to understand what it can do.

	I personally prefer the ETHOS format this year over an in-person meeting.  Of course we all miss personal contact, but the formatting has included plenty of time (can be more than one-on-one) for interesting dialogs.  Five half days is a lot better for me than 2.5 full days and two half-days lost in travel time.  Also able to have many more papers from over-seas.

	
	At the ETHOS site, we have been able to read/view Ppts in advance of meetings with the air time with emphasis on questions - this I much prefer:  See   http://www.ethoscon.com/ethos-agenda-2/

	We all (maybe 75-100??) paid $20 - which is a bargain for what can be almost  20 hours (almost half in semi-public group discussion on spatial.chat.   I have no idea whether those who have not paid their $20 can see the many agenda PPts, but if so, I strongly recommend doing so.

	From my biochar-prejudiced perspective, the best Ppt was that of Tom Miiles - of course on biochar.    Tom gave a  new term for biochar I haven’t seen before -  and recommend that char-making stove enthusiasts advance it:   biochar in soil can be thought of as bio-geo batteries.    Many of us have been pushing biochar as a lower cost back-up for wind and solar than batteries -- so I appreciate Tom's word “storage” here.  Unfortunately not much on biochar use from cookstoves (but see next to last paragraph).

	The shortage of TLUD discussions will be fixed tomorrow when Paul Anderson will be speaking (see above agenda for timing details of Paul ’s talk.   Also Dean Still tomorrow, with a minute or so on Kirk Harris’ latest stove - which Dean calls the best he has seen.   Both will be on about noon EST (the full day starts 2 hours earlier).

	I also recommend a talk by Kevin McLean on Monday.  Partly because of the big cost savings he described using rock beds - but also because of the way the method is being rapidly accelerating. - with a cost of 2c per new adopter (using church groups),    I recommend Kevin’s work also on really low cost TLUDs - not discussed 

	By far the best part of the day for me was Julian Winter saying (during discussions - not a paper)  that TLUD implementation problems in Bangladesh are already over.  There has been such NPP success with farmers using the biochar that their TLUD (a fine one built locally) can’t keep up with demand.   In some cases,  Julian's Bangladesh TLUD is being used only for making biochar (for soil application) - no cooking.

	I hope others can pipe in with other stove types (glad to again see some nice reports on solar stoves).  I’ve not mentioned a lot of good new stove material.
