idea. He described it to me as a flat slab somewhat like the thing you sit on in a wheelchair if you have to be there all the time. It was charged by flipping it upside down and sitting it in the sun. It was ‘ignited’ by flipping it over and the chemicals
inside started to mix and generate heat.<o:p></o:p></span></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">I am fascinated by solar cooking these days. There are many potential socio-economic and environmental benefits of
solar cooking and they are all very seductive. Just thinking about fuel-free and emission-free cooking is intoxicating.</span><o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">However, it seems that it is difficult to achieve the potential benefits of solar cooking (especially in the developing
world) largely because those that dwell in hot climates (which is where much of the developing world seems to be located) have developed lifestyles that minimize exposure to the sun whereas most methods of solar cooking require the cook to be out in the sun,
often at times of the day that aren’t typical cooking times. These facts make the difficult task of changing the cooking habits of cooks even more challenging.</span><o:p></o:p></p>

This amazing innovation is “charged” with the heat of sunshine and the heat is stored in a “sun bucket” (phase change “”battery”) where it can be used when (like in the evening or early morning) and where (like inside a kitchen) it is needed. It cooks as
hot as cooking on fire and existing cooking pots and pans can be used so there is minimal need for changes in cooking behavior. It also seems very affordable. I guess it’s what they call transformational.

using an Improved Cook Stove when it's not, and maybe using a retained heat cooker with both) everywhere the sun shines in the developing world. I can hardly wait for the Sun Bucket to be unleashed to the world-wide market of cooks that could really use them.</span><o:p></o:p></p>
