This is remarkable. Metal that is so light that it won’t sink. This would be an incredible safety feature and save tons of lives. I wonder how long it will take before this is commercially available?
Researchers have demonstrated a new metal matrix composite that is so light that it can float on water. A boat made of such composites will not sink despite damage to its structure. This first lightweight syntactic foam also holds promise for automotive fuel economy because of its heat resistance. The magnesium alloy matrix composite is reinforced with silicon carbide hollow particles and is strong enough to withstand rigorous conditions faced in the marine environment.
What is more remarkable is that things that used to be true with technology change. Isn’t it neat that we can grow and change the world by understanding it? Technology isn’t the answer to lifes problems, but it is an interesting and entertaining toy to play with as we mature as a species.
