<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>
