Giant umbrellas shift from convenient canopy to sturdy storm shield

In a new approach to storm surge protection, a Princeton team has created a preliminary design for dual-purpose kinetic umbrellas, which would provide shade during fair weather and could be tilted in advance of a storm to form a flood barrier. The researchers used computational modeling to begin evaluating the umbrellas’ ability to withstand an acute storm surge.
