<div dir="ltr">Lowtech  magazine just published a piece on a related issue: efficiency of cooking with different fuels:<br><a href="http://www.lowtechmagazine.com/2014/06/thermal-efficiency-cooking-stoves.html">http://www.lowtechmagazine.com/2014/06/thermal-efficiency-cooking-stoves.html</a><br>
<br>"Converting heat into electricity which is then converted back into 
heat, at 20-40% efficiency, is similar to building a Rube Goldberg 
machine; it's a needlessly complex operation compared to simply 
converting the primary fuel into heat to boil water. Essentially, any 
electric cooking device is an insult to the science of thermodynamics."<br><br><br></div>
