<span style="line-height: initial;">The crossdraft stove is I think to displace both because it works without an auger and it overcomes the problem of the batch cooking which is not well appreciated in the field. On the unit of Alex's that I described a little:
if that gear is turned slowly it will produce char continuously by dropping the pyrolysed fuel into the chamber below where it sniffs I the absence of oxygen. </span></div>

<span style="line-height: initial;">Alex uses a similar approach with his huge boiler which has a moving chain grate. By varying the speed he produces the 'finish' he wants on the char used for potting. Fast, it is done to a lower temperature. Slow enough it
produces almost none at all that finished at a high temperature. </span></div>

<span style="line-height: initial; font-size: initial; text-align: initial;">In theory the small one in the photo could be jigged to produce the character you want. I am much more optimistic about doing it to a certain standard with a continuous process than
with a batch, especially where the height of the hot zone changes in height continuously. </span></div>

</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>Thanks. That is a great Ppt. It makes all the right points about carbon negativity. I will be sending this on to the geoengineering list as one of the strongest rationales for biochar
that I have seen.</div>
<div class=""><br class="">
</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>The only name for the stove I see is “Biochar Pellet Stove” = BPS. I am going to call Jerry’s a “WBPS” = Whitfield Biochar Pellet Stove. </div>
<div class=""><br class="">
</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>Q1. There is probably a patent issue here, and similarly for a few TLUDs. But generally no patent issues for TLUDs. And the use of augers must be beyond patent protection now. Can
you/Jerry clarify on intellectual property issues surrounding the WBPS?</div>
<div class=""><br class="">
</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>Q2. One quibble on slide 9, which shows 9 Gt C/yr removed by BPSs - half (4.5 Gt C/yr) via char. Critics of biochar will say you can’t claim the upper equal amount which returns
to the atmosphere as CO2. BECCS proponents claim superiority (incorrectly) because they can sequester (deep underground) a larger (and controversial) percentage. I think you need a modification to Slide 9 showing the out-year benefits - as the initial char
placement can probably generate another follow-on 4.5 Gt C/yr. Or is this already in your (plural) thinking?</div>
<div class=""><br class="">
</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>Q3. I don’t mind at all the number 9 Gt C/yr - but is there some further justification for that (large) number? Is it perhaps supposed to include co-production of biochar with bioliquids?</div>
<div class=""><br class="">
</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>Q4. The obvious conclusion from the (again, excellent) slides, is that the WBPS has not yet found an angel investor. Can you (plural) say a little more on this. Is this the main
holdup in going further now? </div>
<div class=""><br class="">
</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>Q5. I was unaware that the pellet stove business needs help that biochar can supply. Is this commonly accepted? Was there discussion of this at the conference?</div>
<div class=""><br class="">
</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>Q6. There is obviously a big advantage to not having a batch process. Could this hopper-auger approach be practical soon for industrial cook stoves?And even to overtake TLUDs eventually?</div>
<div class=""><br class="">
</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>Q7. I like seeing the emphasis on reducing excess air. What sort of ratio of primary to secondary air is desired?</div>
<div class=""><br class="">
</div>
<div class=""><span class="x_Apple-tab-span" style="white-space:pre"></span>Q8 I’m ready to place a WBPS order. When will (or might) it be welcome? Do we have to wait for carbon credits? Some countries have some.</div>

<div class="">A very interesting stove built expressly to drive a TEG was shown in April at the Brookhaven National Lab. It had one moving part - a fan, burned pellets - could be fed from the top, was clean burning, powered some lights and charged a battery.
It was not configures with a cooking surface, but that would be an easy upgrade. As designed, it did not produce Biochar. It was a 100% combustion device. It was designed for off the grid living and survivalist needs.</div>

<div class="">Dear Hussein,<br class="">
<br class="">
Thanks for your thoughtful reply. As you can see from the separate replies by Andrew Heggie of the UK and Erich Knight in the USA, this topic is of interest to many of us.<br class="">
<br class="">
I and Nolbert of Awamu in Kampala are interested in your development of a workshop for stove production.
<br class="">
<br class="">
The use of some of the generated power to operate a small fan on a TLUD-FA stove is of interest, but (as you surely know) natural draft units are also able to give the needed heat. BOTH avenues are of interest.<br class="">
<br class="">
How open are you to collaborative efforts about linking the TEG in TLUD stoves? The "TEG-TLUD" efforts could become collaborative or competitive, depending on the desires of those involved. I favor collaboration.<br class="">
