@neauoire@rek this looks interesting. Habe you got a link where someone could aquire something like this? I imagine it needs full sun? (No cooking on cloudy days).
@Katharina@rek there are a few companies that sells them. We found a local importer of those. Look at the local hardware store, otherwise if no options are available, some grocers might be able to order the tubes.
If you're in Europe, you're lucky, there are often group buys of those and workshops.
We managed to cook with an overcast 2 days ago, it just took longer.
