Attached: 3 images **Solar cookers built in Spain for #Cuba** https://groups.io/g/cubanews/message/54040 from #CubaNews June 7, 2026 >A workshop on the construction of solar cookers was held this Saturday, June 6, in #Madrid, #Spain, with the aim of sending them in July to schools in #SantiagoDeCuba. >The workshop resulted in the construction of 13 concentrating #solar cookers. >Solar cookers are mainly built with cardboard and aluminum foil, they are detachable and easy to move. To operate it also requires a pot, preferably dark, and a glass bowl or even the door of an old washing machine, elements that allow the greenhouse effect to be generated to concentrate the solar heat. >At the end of the construction, two cookers were tested in the courtyard and it was shown that it reached boiling in a few minutes. >Thanks to this system it is possible to cook food using only the #energy of the sun, without the need for electricity, gas or firewood. #OilForCuba! #CubaSolidarity #CubaIsNotAlone #SustainableEnergy #news

    This is really positive, not only utilising free energy it negates the short and long term health concerns associated with burning fuels.

      it delivered, but required a russian naval escort to ensure that the us empire’s navy didn’t try to block it again.

      not that it matters much, it was a splash in the bucket compared to what cuba needs.
