Since the era of commercial electricity dawned in the late 19th century, electrical devices have relied upon wires, which are connected either to a generation source or to an electrical storage unit such as a battery. Things would be a lot simpler if the electricity could be moved directly from the generation source to its place of consumption without wires or batteries. Over the past century, a number of researchers have examined this possibility, but it has only been in the last few years that such solutions have become feasible. What will this technology look like? What are the benefits? What are the relevant threats and opportunities? We’ll show you.
