Hi Policy & Stovers,<br><br>In my general advocacy duties,<br> I spoke with Valerie Reed at EE.DOE, the Office of Energy Efficiency and Renewable Energy, Office of<span class="ib" style="width: 0.54em;"> </span>the Biomass Program.<br>
I sent my industry & news updates to her after our conversation, she was aware of biochar efforts, which allowed me to pile on stuff from ISU etc.<br><br>She was excited about the scale & scope of the stove initiative with Dept of State, CDC, EPA & DOE and lamented that funding won't be til 2011.<br>
<br><br>Cheers,<br>Erich<br><br><div class="gmail_quote"><br><br><br>On Sun, Dec 5, 2010 at 4:30 PM, <span dir="ltr"><<a href="mailto:rongretlarson@comcast.net">rongretlarson@comcast.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">

My first words were: "<i>I like all parts of your message below.....</i>" and later " .<span style="font-style: italic;">.thank you for being blunt.."</span>. I agree I was lengthy on Nat, but I felt it important to do so - because I feel Nat has explained a lot more about his stove than you were giving him credit for. Do you know anyone with more stove videos? I was also trying to emphasize that his Lucia is very different and I hope others will pick up on some of his corporate techniques (as I gather things are going quite well). I think the subject line was fine as is - and I change a lot of subject lines. Your "too closed" was what I took to be the subject.<br>
<br> 2. I think I also was on topic in talking about the problems of stove-related corporations - even non-profit ones. We cannot expect full disclosure of every stove detail when people are trying to make money - and might be losing it - and/or trying hard to avoid future losses. We need both corporations and volunteers - but we especially need the former now.<br>
<br> 3. I am now being redundant, but I (like you) hope everyone will share more stove data. But it is not easy to do. I'd rather get none than crappy data. Fortunately, this new global stove program should/will have some money to put into really thorough testing. In Dean's (and those at CSU or Berkeley, etc) defense, I presume there have been few people batting down their doors to fund a wide range of stove testing - especially as independent third parties. I know Nat has paid for his own - and presumably does release right now to those who he feels he should be working with. I have not seen any of his detailed test data.<br>

<br>><br>> Paul and ccs (adding "Biochar-policy")<br>><br>> I like all parts of your message below with one exception - thank <br>> you for being blunt. The exception is your statement that World <br>
> Stove (Nathaniel Mulcahy) is acting like the other four in your <br>> five-corporation secrecy list. Today, Nat recommended a new video <br>> that I found clever but in no way informative about the technical <br>

><br>> Because I have been to his Italian facility and played with several <br>> Lucias with several fuels, I can assure everyone that a careful <br>> (cursory won't do it) review of what is shown and stated there (and <br>
> you wouldn't need one in hand) would allow one to duplicate it and <br>> understand its principles of operation completely. Nat's is truly a <br>> remarkable invention - I know I could not have developed it myself. <br>
> This video is the complete opposite of secrecy.<br>><br>> With several presentations at stove, Biochar, and UN-sponsored <br>> climate meetings, Nat has freely discussed how it works and has <br>> passed it around for close examination. He is showing a totally free <br>

><br>> Having said that, I now take issue with Dean and the apparent<br>> Aprovecho approach which is:<br>><br>> 1. Not providing all of the information that the others want to have<br>> about what testing is going on with the TLUD stoves.<br>
><br>> 2. At Aprovecho, not involving to any noticable extent any of the<br>> pioneers or other experienced advocates of the TLUD stoves.<br>><br>> 3. Having made a major shift of direction from many years of "polite<br>
