<DIV><BR></DIV>
<DIV>Congratulations on your efforts. Will look forward to seeing
further developments.
<DIV><BR></DIV>
<DIV>We found it interested that ASAT/Aprovecho (ARC) awarded a $100K SBIR
grant by the EPA for a TEG cook stove, due to ARC's claim <I>they
specialize</I> in thermoelectric generation cookstoves.</DIV>

specializes in heating, cooking and thermoelectric generation (TEG)
technologies and has developed clean biomass cooking stoves with Department of
Energy grants."</SPAN><BR></DIV>

<DIV>We will be curious to see if the champions of the WBT's TEG stove
currently exists, or will perform as poorly as their emission equipment did
previously' or maybe they are stoned as usual.</DIV>
<DIV><BR></DIV>
<DIV>We will launch a side fed TLUD thermal electric stove 2nd or 3rd quarter
of 2017, that is currently in actual production to measure market
interest. The EPA sure could have saved a lot of grant money for
technology that is already in production. Unless subsidized,
unfortunately quality TEG cook stoves that deliver more than 5 watts of power
are going to be difficult to produce at low cost to the BOP, in our
experience.</DIV>

<DIV><SPAN>The provision of heat in remote areas is a long term human need.
Getting electricity for basic needs is also a prime
requirement. </SPAN></DIV>
<DIV><SPAN><BR></SPAN></DIV>
<DIV><SPAN>Jeremy and I have been looking at ways to bring light from stoves
(and heaters) using relatively low grade sources (below 180 C).</SPAN></DIV>
<DIV><SPAN><BR></SPAN></DIV>
<DIV><SPAN>Attached is our experiment using a metal plate as the heat
source, a very inexpensive booster, a USB port and a high efficiency LED.
The middle photo is illuminated by the output from the
generator. </SPAN></DIV>
<DIV><SPAN><BR></SPAN></DIV>
<DIV><SPAN>We are using a thermoelectric cooler running backwards. The cost
of the three TEC's plus the 5 vdc booster and the HE-LED is about $7.50. The
plan is to keep it as cheap as possible, and separate from the stove.
</SPAN></DIV>
<DIV><SPAN><BR></SPAN></DIV>
<DIV><SPAN>The input temperature can be up to 250 C and we used a pot of
water to cool the other side. It lights up the LED bright enough that it
requires cooling. We will stick it onto a small rectangle of aluminum
sheet. </SPAN></DIV>
<DIV><SPAN><BR></SPAN></DIV>
<DIV><SPAN>This choice of components is useful far beyond the provision of
light because it was able to charge a BlackBerry Passport and a dual lens
infrared camera. We also successfully tried an AAA battery charger.
</SPAN></DIV>
