Dear Ron and Andrew

How is this different from what Paul O has been making for several years? The quality of the workmanship is Vietnam is very high.

How is the fan powered?

Recently, I've had some interesting dialogs with Paul Olivier.   If you go to www.eslra.com<https://nam03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.eslra.com&data=02%7C01%7C%7C7f420f923765406dc09e08d674b96f7b%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636824737115090128&sdata=8yCOLEjk2IThBp8f7wNXDMq%2BJepMarkvLB%2BH96fH%2BPM%3D&reserved=0>, and http://epwt.vn/en/home/<https://nam03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fepwt.vn%2Fen%2Fhome%2F&data=02%7C01%7C%7C7f420f923765406dc09e08d674b96f7b%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C636824737115090128&sdata=p2uX%2FhMZFm7UHozeAzoeq9pvHXq9WyXO9frzBu6CpNE%3D&reserved=0> you'll find more like the content which follows (whose 1.2 MW size I hope is not too much - and perhaps Andrew can find a fix, if needed).  This sort of stove is available in Vietnam for about $75.  Mostly stainless.

Paul is looking for places in other countries to hand off large scale manufacture and/or assembly.  Dies for the manufacture of parts can be obtained - at cost (Paul not in this to make money).  Paul can supply more information to anyone interested in getting into large-scale activities.  But lets be respectful of his time - general simple questions shouldn't be one-on-one.

But independent of that, I hope all will look carefully at the photo below (sixth from end) showing the best pyrolysis gas flame I have yet seen.  Nothing wispy about this.  I don't have all the details, but I don't recall any TLUD design like this - which clearly only has a flame just below the cookpot.  No secondary air or flame anywhere near the char-bed.  Paul has not yet calculated turn-down ratio - but it is large.  With pellets, this height stove can last for more than three hours.  With rice hulls, less than an hour.  He can fill the stove near to the top - so considerable savings on materials above the unlit fuel.

There are 80 small holes - giving 40 flamelets - obviously groups of 2.  What is the general principal here?  How can the hole design be changed to get 80 shorter flames?  Or 20 larger?  Or is 40 about the right number?  Should we be thinking slits?

Your thoughts on Paul's advances?

Ron
