So far I am not feeling encouraged about this design’s ability to REALLY heat water. But it is a fun project made completely from “trash”. Thanks much to Suz…

i think you need to focus on heating the bottom, because hot water rises,
right? So if you focus on heating the top, you will just get super boiling
water up at the top, but it is not necessarily going to go down. On the
other hand, focus all your heat source at the bottom, and the water will
rise as it is heated.

Just an idea if you didn’t think of it already, would be to put the barrel
on a turntable so it can be turned to face the sunlight better if it was
put into a box with a glass window, maby double-pane type, and the other
two sides could be mirrors..and insulated on sides and back.
That glass box idea is great as in Denver I used scavenged double-paned
patio doors to make giant hotframes for winter gardening. If I can surround
the barrel in some fashion with double paned windows and still access the
spigot and be able to stir the water before use I bet I’d get MUCH hotter
water. Thanks for that great idea! John
Thanks! So far it is not doing a very good job, so I will keep playing
around with differing reflectors and their angles. Fun to experiment with
free stuff like this!
