Physicists at the Australian National University have created a tractor beam in water. Using a simple wave generator they can create water currents which could be used to confine oil spills, manipulate floating objects or explain rips at the beach.
GE’s DCJ technology is an advanced cooling solution for the next generation of thinner, quieter and more powerful tablets, laptops and other electronic devices. These devices, as thin as a credit card, are half as thick as conventional cooling fans and use half the energy. And, GE’s technology is quiet, it is virtually inaudible to the ear.
