“As with all mining methods, it will still impact the environment,” says Henning Prommer, an environmental engineer at the University of Western Australia, Perth, whose group has worked on applying electrokinetic mining to gold and copper.

Now, a Chinese group has developed—and tested on tons of soil—an approach called electrokinetic mining that relies on electric currents to free the REEs, sharply reducing the need for polluting chemicals.

Now we know that the “eye of the needle” is just another name for a gate in Jerusalem—and with the Swarp XE-ll’s mega-lepton lift and electrokinetic gyrostasis, you can flip ninety degrees to the ground and back again in one-point-two seconds—so getting through the gate just won’t be a problem anymore.

The motion of the tubes with their ends on the wire represents a certain amount of energy, commonly regarded as kinetic, and styled electrokinetic energy.

If c denote the current, that is, the rate, − dQ/dt, at which the charge of the condenser is being changed, and L a quantity called self-inductance, depending185 mainly on the arrangement of the connecting wire—whether it is wound in a coil or helix, with or without an iron core, or not—the electrokinetic energy will be ½Lc2.
