Squid Jet: Underwater Propulsion

Alex Spiride, USA Finalist, 13-14

Squid and some other sea creatures use a very efficient mode of locomotion, know as jet propulsion. Squid will draw water into a bladder through a hole called the mantle, and then they force it out, by contracting the bladder, to shoot forwards in speeds of up to 40 km/hour.

Implementing this technique in underwater vehicles can vastly improve the efficiency with which they locomote. My proposal is Squid-Jet, a bio-inspired underwater vehicle that uses jet propulsion to its advantage. Squid-Jet easily outperforms current manmade propulsion systems and can reach speeds in excess of 30 cm/second.
