Martin McCall, Professor of Theoretical Optics at Imperial College London, predicted that invisibility cloaks similar to the type Harry Potter had in the films would be available by Christmas of 2014 in the Dec. 18, 2013, issue of the journal Contemporary Physics.
McCall claims that all the technology and materials as well as several prototype demonstrations have made the possibility of having an individual invisibility cloak available in the near future at a price most people could afford.
Andrea Alù, associate professor in the Department of Electrical and Computer Engineering at the Cockrell School of Engineering at the University of Texas at Austin, and his team proposed the development of a battery powered invisibility cloak on Dec. 18, 2014, in the journal Physical Review Letters. The battery powered device could draw energy from electrical sources in any area and the concept overcomes present limitations on time of use for presently working invisibility cloaks.
The military may preempt any retail sales of invisibility cloaks of the most sophisticated nature but there is no reason to think that a patent for a cloak could not be devised and mass produced in time for Christmas in 2014. The potential for using such deices as a cover for theft might prevent retail sales.
One could only imagine parent’s joy at losing their children or hiding from them at least for a little while during the holiday season thanks to a gifted invisibility cloak.
