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 !!
