No sé ben bé com comení§ar aquest apunt… xerrant clar, sa NASA té un producte anomenat AEROGEL que podria tenir mooooltes utilitats i ningíº sap que existeix.
N’exposen unes breus caracterí­stiques:
- It is 99.8% Air
- Provides 39 times more insulating than the best fiberglass insulation
- Is 1,000 times less dense than glass
- It has low thermal conductivity, refractive index and sound speed - in addition to its exceptional ability to capture fast moving dust
- Aerogel is made by high temperature and pressure-critical-point drying of a gel composed of colloidal silica structural units filled with solvents
- Was used on the Mars Pathfinder rover

Sa Galeria de imatges parla per si mateixa, una esp�cie d’espuma que sa seva composici� �s b�sicament aire i que amb 2 grams es pot aguantar un totxo de 2,5 kilos….
