No âmbito da produção de materiais alveolares do futuro, estão descritas 11 patentes de invenções. Foi desenvolvido um conceito de construção computacional de estruturas metálicas fundidas leves com estrutura alveolar. Com base na análise das estruturas de substâncias inorgânicas, tal como apresentadas pelas ciências naturais, foram propostas estruturas alveolares de peças metálicas fundidas, inspiradas na estrutura de estruturas cristalinas e amorfas, do diamante, da estrutura de quase-cristais segundo o mosaico de Penrose e de nanotubos de carbono, bem como métodos de fabrico de modelos em espuma para os mesmos na oficina de fundição. As construções das peças fundidas e o método de montagem de conjuntos de modelos em coletores de vários andares foram realizados segundo o princÃpio do fenómeno botânico da filotaxia, com base em modelos da geometria fractal, por analogia com estruturas arbóreas e a estrutura do ADN. São apresentados modelos de peças moldadas com estrutura de armação e alveolares, que preenchem de forma ótima o espaço no interior da forma de areia, bem como a sua fabricação tendo em conta a teoria das superfÃcies mÃnimas, à semelhança da estrutura de espuma com alvéolos na forma de dodecaedros pentagonais.
