I understand that _consumer_ wireless power has not yet achieved its full potential. But those systems do not represent the entirety of wireless power... For example, RFID access cards (like those found in student IDs) use wireless power to transmit their ID. Quite ubiquitous, and definitely not "useless". There are also examples of robots using wireless power to great utility -- again, not "useless" http://www.hizook.com/blog/2008/10/07/wirelessly-powering-swarm-robots http://www.hizook.com/blog/2008/10/07/wirelessly-powering-sw...
