Seagel (Safe Emulsion Agar Gel), a solid lighter than air, is the latest development in research into extremely lightweight materials. Invented by Dr Robert Morrison and developed at the Lawrence Livermore National Laboratory in California, Seagel is primarily made out of agar - a seaweed derivative. It is biodegradable and so non-toxic you can eat it. The potential applications of Seagel are enormous. it is a rapid absorber of energy and as such can be used for shock absorption, sound and heat insulation. In the medical field, due to its porous structure, it can act as a slow release pad through which transdermal medication can be administered. And it is possible that Seagel may replace balsa wood imported from the tropical rainforest of South America. this is used in everything from the manufacture of toy aeroplanes to sound insulation on trains. Seagel makes and environmentally friendly alternative.
