</div>
<div name="BB10" id="BB10_response_div_BBPPID" dir="auto" style="width:100%">A regular TEG creates current across the line of contact between the two metals that are heated and cooled, that is, along the glue that joins them. As a result the generator is a
large number of tiny generators soldered together, directing the electricity towards the cold side. </div>
<div name="BB10" id="BB10_response_div_BBPPID" dir="auto" style="width:100%"><br>
</div>
<div name="BB10" id="BB10_response_div_BBPPID" dir="auto" style="width:100%">The new invention produces a current in the same direction as the heat flow. As a result the generator occupies the entire surface and is not made of a lot of tiny parts. The whole
surface is "generator" and it has no circuitry. There is therefore a far simpler fabrication process. I understand it is baked twice, first at more then 1100 C then again higher. It means it will be able to operate in a flame environment as far as I conceive
it. Being cooled continuously on the back means the front face could be very hot so no need for thermal bonding.</div>

<p class="MsoNormal">This is really of interest to people living in Ontario, however it points a way forward to include more biomass-fired heating and cogeneration of electricity.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">It is public knowledge and posted here to stimulate discussion.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">There is a new technological breakthrough for Thermoelectric Generators (TEGs) which should hit the market in a few years. It gives a dramatic improvement in conversion efficiency (heat to electricity). According to disparate sources,
the efficiency might be in the range of 35% and the cost is slashed. We can talk of $100 per KW for the modules.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">The laws in Ontario have been updated with advice from the CSA technical committee rewriting B415.1 – the standard for space heating appliances that burn wood. There is even a new method for assessing the emissions of site-built masonry
heaters in B415.1. The general idea is to promote wood fuel over diesel in remote communities.
<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">As new TEGs become available, it is a very attractive option and smaller and smaller scale.<u></u><u></u></p>
