To track the movements of sharks I suggest using solar-powered tags able to beam location information to satellites. The sensor-laden tags will be used to track certain endangered shark species in order to understand their migration patterns. Previous tags relied on battery power to remain operative and the batteries would often die before all the information could be transmitted. Because most sharks do not stay long near the surface of the water (where the sunlight would...

In order to reduce the number of shark attacks, I suggest tagging the sharks with a device that will send a Twitter message as a warning to surfers and swimmers. To create so-called Shark Monitoring Network, it is necessary to attach transmitter tags to sharks to track their location along the coast. The tags will communicate with a network of floating monitoring devices that will pick up the signal of an approaching shark and trigger an alarm that will be sent on a Twitter feed....

The Wave Glider robot smartphone app will let armchair divers check on the location of the nearest Great White Shark from the safety of their living room. The wave- and solar-powered Wave Glider is an autonomous robot with exceptional endurance, able to find and follow tagged sharks, as well as other sea life. It is developed to track tagged fish and animals through a Wi-Fi network. The current methods used to track marine life--tagging and catching or satellite relays--both lack...

It is known that a basking shark feeds by swimming with its mouth open. The shape of the shark's body plays an important role in its efficiency as a feeder. A pressure differential is created as the shark swims, resulting in lower pressure along the shark's top and helping to draw water out of the shark's gills in a way that allows it to rely on the passive flow of water to feed. Why not design a turbine with the shark's design in mind? Water enters through the first turbine while...
