The present invention relates to a multicylinder internal combustion engine with a cylinder head and with a cylinder block, which are fixed to each other by screw connections, where, between tie cylinder head and the cylinder block, a cylinder head seal is arranged, where, between two cylinders, a separate stress-relieving groove in the cylinder head is associated with each cylinder. The midfoot section of the insole device has a receptacle located central to the foot’s anatomical arch apex that receives interchangeable resilient ellipsoidal and spherically shaped biofeedback catalysts of many shapes and forms. Also preferably, the invention provides for full retraction of the curved traction elements. The power source may take on a variety of forms including another battery, a photovoltaic array or a direct plug connection to a electric wall outlet, Universal Serial Bus port or a telephone jack. The method further includes transferring by the data processing system the group of elements to a destination.
