TED-Ed educator Alex Gendler explains the origin of tsunamis and why the term “tidal wave” is a bit of a misnomer.
The immense swell of a tsunami can grow up to 100 feet, hitting speeds over 500 mph — a treacherous combination for anyone or anything in its path. Alex Gendler details the causes of these towering terrors and explains how scientists are seeking to reduce their destruction in the future.
A Japanese company has developed a material that cures within one minute and has a tensile strength more than two times that of concrete. For cities affected by natural disaster, this “CO2 Structure” could help reconstruction happen faster.
Concrete usually takes 28 days to cure to its full strength. By blowing CO2 into silica, TIS Partners LTD was able to make the silica into a substance as hard as brick, as reported by DigInfo TV (via Gizmodo). TIS Partners President Norihide Imagawa said they then increased strength by adding epoxy or urethane.
