Meta-material performance is disappointing

I read the paper.  The peak simulated power transfer efficiency is 6% at about 14 cm.  If there were no fancy metamaterials, it would achieve 6% efficiency at 10 cm, and the efficiency is much higher at smaller distances.

I don't see it being more than a laboratory curiosity for a long while.

It's a clever design and looks like it lends itself quite well to their next enhancement -- the addition of dynamic tuning. If implemented in a smaller & thinner form factor, this approach could also do wonders for wireless charging pads for mobile devices.

Agreed, a technology that can boost the wireless transfer of power involves a whole range of possibilities. We shall see how this plays out and where it ends up being used.

The concept of the 'Superlens'  for wireless power transfer is quite interesting. This could be very useful for charging of electrical vehicles as they can be charged while on the move by the proximity magnetic field .

I think a similar approach has been used for the driver less electric vehicle , I saw , on some other blog .

To say that Andy Weir's The Martian is an exploration of math, Mars, and feces is a slight simplification. I doubt that the author would have any complaints, though.
