Looks to me like an updated/better Power Over Ethernet, makes sense in the long run as most devices we use now are low power needing DC. I remember some years ago having a conversation with a very experienced consultant electrical engineer who designed large scale power systems. He siad if we were to start again we should use high voltage DC not the AC of Westinghouse/Tesla as we can now control it much more easily.
So maybe this is the future of power. Nothing works until it has negotiated a safe connection, just think of all the fun troubleshooting that! Probably won't be widespread within the life time of the members of this forum though.
