A solar oven of variable power (size of the box) and adjustable inclination for a few € ...

Need an explanation?



To find the bell ideally glass (a large salad bowl) if not plastic, there is in the garden center as a forcing bell!

You can also use mini seedling greenhouses ... this one is 102 x 61 x 41/31 cm:

Obviously. Temperature rise curve of the quantity heated, as a function of time, sunshine, the volume of the pot, the mass heated inside and the color of the pot.
Seems so effective to me that it must even work at night with moonlight, right?

Bad language !!!

If you concentrate 1 m2 at the level of the bell you will have more than 1000 W !!

The model in the photo deserves to be reworked with a real geometric study !!

AaH ah ah lol ...

A solar oven not wanted in London!



You see that it heats up Exni !!

No, it's the opposite for lunar light, because it is polarized. (“cold” light)

Polarized light can be very focused.

I didn't talk about Focale.

The problem... is that no one knows what you're talking about!!!

When we think we understand, it’s because we don’t understand.
