<p class="MsoNoSpacing"><span style="mso-fareast-language:EN-CA">We have had demonstrations of cooking oil as a fuel, with the Protos Stove (now deceased) as one possibility that was tried for years. Here is a paper looking at the straight displacement of
coal by waste cooking oil, based on a technology that is already on the market – an electronically controlled waste oil burning space heating stove with a novel (very small) combustion chamber.<o:p></o:p></span></p>

<p class="MsoNoSpacing"><span style="color:#2E2E2E">• The production of WCO in China has a great supply potential for coal substitute.<o:p></o:p></span></p>
<p class="MsoNoSpacing"><span style="color:#2E2E2E">• Coal-to-WCO shift reduced pollutant emission from rural households in Northern China.<o:p></o:p></span></p>
<p class="MsoNoSpacing"><span style="color:#2E2E2E">• The co-benefits of decreasing mortality risk and fuel costs were also significant.<o:p></o:p></span></p>
<p class="MsoNoSpacing"><span style="color:#2E2E2E">• The household-source emission of greenhouse gas was effectively controlled.<o:p></o:p></span></p>
