Hi all:<br>
We (Masonry Heater Association) did the emissions and efficiency testing on<br>
the TEG stoves.<br>
We had a volunteer crew of 5 MHA heater masons and 3 of our Condar portable<br>
dilution tunnel sampling systems and Testo 300-2's.<br>
We also got to do a run on the Oekofoen pellet boiler with Stirling add-on,<br>
and on an Oekosolve<br>
electrostatic precipitator from Switzerland.<br>
Brookhaven National Laboratory brought 2 teams to do the testing on the<br>
automated stoves.<br>
<br>
Here's a photo story I put together:<br>

Thanks for the feedback<br>
I found this resource on line, they package in the form of a chimney strap<br>
used up to 230C.<br>
MFG in Vietnam.<br>
<br>
At around 40$ for a single 1.2w module I imagine the strap with 8 or more<br>
modules, heatsinks and controls must have quite a sticker shock price.<br>

Thanks Norbert, good write up, I have yet to follow up some of the links.<br>
<br>
Whilst most of the burners depicted are for space heat (and power) in<br>
the developed world the techniques show promise for more universal<br>
use.<br>
<br>
I was particularly interested in the 30kV electrostatic precipitation,<br>
yet it only reduced particulates by 62%, I was expecting more, before<br>
I read up on it do you remember its power consumption?<br>
<br>
Also the nano particle counter next in your report, it mentions a 1nm<br>
cut off, can you say whether it is cutting off less than 1nm and<br>
sampling larger? Presumably below are at the molecular level as I<br>
think the size of a water molecule is around 1/3 nano metre.<br>
<br>
Thanks<br>
<br>

<br>
Thank you. I agree with Todd - "Handheld photovoltaic battery charging<br>
units currently available offer more capacity and storage, as well as being<br>
more cost-effective and viable is my point. "<br>
<br>
However, solar insolation is lower in England, and heating needs are<br>
greater. Everything is contextual.<br>
<br>
My Chaiwalla Prime Minister distributed solar induction stoves for tsunami<br>
shelters and some households in the islands of Indian Ocean -<br>
<a href="http://echoofindia.com/port-blair-pm-inaugurates-clean-cooking-electric-vehicles-schemes-isles-142974" rel="noreferrer" target="_blank">http://echoofindia.com/port-blair-pm-inaugurates-clean-cooking-electric-vehicles-schemes-isles-142974</a>.<br>
<br>
<br>
" The Prime Minister, Mr Narendra Modi inaugurated two projects on clean<br>
cooking and electric mobility in these islands on Sunday. Introducing 99<br>
Tsunami Shelter Homes to a clean, comfortable and hassle-free cooking<br>
option, the Prime Minister distributed Solar PV-based induction cook stoves<br>
to households at Chouldari.<br>
<br>
<br>
He is known to spot fads very well, and may well have judged that solar<br>
induction cooking is a better bet than stoves with TEG.<br>
