A fresnel lens will boil that oil in 5 minutes. Check out greenpowerscience on yt.

looks good , if you want more heat i suppose a thinner pipe and some fins or something to collect more heat for the pipe ? The weather in the uk wouldnt be much good for this , only a few hot weeks a year lol

@luc59457 : I realized the part about the "oil" after I watched the rest of the video! So I removed my comment, but thanks for responding. Looking forward to more of your videos.

@BuickDoc Those words weren't referring to Canada.

Get rid of the foil. You are reflecting the heat AWAY from the oil. The black container is good, oil is good, tube is good. Now cover it with clear anything. This little unit will work pretty good then.

@MultiBlenderman How about another pyrex cover, with a fresnel lens for the top as well, double heat penetration. I've mentioned this a while ago.

Does tin not reflect heat back? Wouldn't a black surface be more effective? Just curious.

@meadman718 ..And a pyrex at the top would be less efficient than a thin metal like tin because heat can penetrate through tin much faster than pyrex. So Pyrex and other materials that take longer to heat will also have the result of holding heat in longer.
