It isn't meant for energy delivery, but energy harvesting. Put a metal stick in place of the antenna, the same power is harvested, but dissipated away. I can see this useful for very low power devices. I don't have specific example in mind, but you can picture something like sensors embedded inside smart concrete high-rise buildings, that alert when crackling is found.
