No, not three pots of curry powder. It's a teaspoon of each except the garum masala (1/2 tsp). See recipe at top of page!

Some update on my solar oven, I have improved my system and managed to reach 90+ on Saturday despite the clouds. It's only the beginning of April so I should be able to cook something soon!

Still can't see your website - is it offline in the late evening? I've tried firefox and IE and both fail.

Ivan,
       On his home page he gives "opening Hours" as 07:00 to 22:00 mon-fri and 08:00-22:00 @w/e this probably means that a night owl like yourself gets around to trying too late  Wink

Hi,

Indeed my website is off at night because I host it on my NAS server and I want it off when the sun is not up... Sorry. Besides today I am away from home and I notice I can t access my site, I think I left it on the internal IP address after I did a clen up yesterday.... Shouldn t drink before I play with me server, even if it's French, red, 1995 and golden medal.... Serves me right!

I'll put this back on tonight when I arrive at 7Pm, in the meantime it might come back on theexternal IP but not sure, I'll have to study that.


When using the navitron Tube for boiling water, can you tell me exactly the one to choose (glass only or complete?)

Cheers,

Stef

About Trackers...

In order to boil water and cook some nice organic charlotte potatoes, I kept moving the cooker towards the sun... So I was thinking about making a tracker.

This morning the sun was out, great weather for the day, But I had to work... Nevermind, I did leave the cooker in the garden, facing sun with 4 big potatoes in it. I left at 9:30, the cooker was then in the sun but in the right direction (SOuth) for later in the day.

I came back at 5:00 and the potatoes are cooked, just right, not dry nor crunchy, just right.


So I will leave the tracker for now and just put the cooker at the right place and leave it all day...

The beauty of the solar tubes is that they don't need a tracker, and work well in overcast conditions from April-September. Although your oven is capable of higher temperatures if it is tracked, and if it isn't overcast.

You need only the glass tube. You don't want the complete unit (which has copper heatpipe). There's also a cork stopper with a small hole for steam and a metal spring clip available....although I'm not sure if they're on the website.

The 47mm glass tube holds approx 1.4litres of water and the 58mm tube holds either 2.2 or 2.6litres (I think it's the latter).

i really like the idea of preheating my evening cooking water by using a tube.

can i remove the heat pipe from a standard tube?
I'm just about to finish up a 36 tube system, which should more than provide during summer (i've gone for antman CH Heat Dump)
But it might be that i could remove a tube or two to use to preheat cooking water during summer and also benefit the overheating situation in the solar system.

Yes, just remove the heatpipe and the aluminium bits, and store them somewhere safe.

We use ours almost every day between March and September. Not only are you saving energy (0.15kWh each time you use it, and that's before you count the wasted heat in heating a kettle full of water you don't need or use), but you have instantly available hot water - which can shave 10minutes off cooking time as you don't have to wait for the water to come to the boil. Watch out on sunny days, if it's left to its own devices for several hours, it can boil half the water away.

In my head, I have a plan for a solar pan....take a normal pan and insulate it (not sure how to achieve that); the base of the pan has, say 4 heatpipe ports brazed into it, so it's heated using 4 solar tubes.

how about  a sort of water boat and put the normal pan in that to cook the food (you could then super insulated the boat, use the hot water as a transfer medium, plus it would mean you can use and normal pan/ caserole dish and it would be very easy to removed cood food from in that way.

You could posibly do away with the copper heat pipe all together, although I am not sure how you could get it to seal to the boat? Maybe some 120 downpipe tube silicone sealanted to the top of the tube and bottom of the boat that way you could then angle the tube at 60?
