Here I was, sittin' around bored and, EUREKA! (damned beans), a memory and a subsequent thought. I remember, around 25 yrs ago, knowing this old guy who lived in his bread truck, which was nicely kitted out. He had this really skookum setup for hot water, which consisted of a few turns of tubing in a hot water tank, the tubing being plumbed into hi s engine coolant. All he'd do is fire up that puppy for a few minutes (or just drive somewhere) and PRESTO.. hot water!<br> Well, skip to now as I wallow in aged decrepitude whilst perusing the forum posts; looks like some people are striving for a cheap way to cook without an oven and, often, while driving. Well, it wouldn't be all that hard to do basically the same thing, but with the coils submerged in a pot.. either a double boiler setup or direct immersion with SS coils. Whadya think? Am I crazy.. or am I just Willy? <br><br>
