Abstract: A system for the cryptographically-secure, autonomous control of devices comprising, connected to or remotely operating devices in an electrically powered network and the transaction of the benefits, costs or value created by or transacted through the devices in this electrically powered network.

Abstract: A grounding electrode suited for installation in very hard or rocky soil is a long conductive metal rod having a drilling bit at one end and a head adapted to mate with a drilling tool, preferably a hammer drill. The grounding electrode, together with a suitable connecting wire and a clamping device clamping the wire to the grounding electrode form an electrical grounding system for a home or commercial structure.

Abstract: An extension handle for a portable vacuum includes an elongate shaft having a proximal end zone, a central zone, and a distal end zone. An attachment bracket for attaching the elongate shaft to a handle portion of the portable vacuum includes first and second pivoting members. The distal end zone of the shaft attaches to the first pivoting member which includes a finger extending therefrom, with a tip of the finger positioned in operative proximity to an on/off switch of the vacuum. The second pivoting member attaches to the handle portion of the portable vacuum, wherein pivoting movement of the first member relative to the second member results in operation of the on/off power switch to respectively activate and deactivate the vacuum.
