Techniques for incorporating nanotechnology into decoupling capacitor designs are provided. The power source includes an engine and an engine fuel system of the type that generates fuel vapor containing hydrocarbon material. The system according to the method allows the cost-efficient production of electrical energy and cooling using low value heat source. In one embodiment, the housing is a computer. The IC also includes several configurable interconnect circuits that configurably couple the logic circuits. The fringes allow for superior grippability of the ball, which is ideal for training or rehabilitating elderly or injured persons who may not otherwise be able to grip a typical exercise ball or medicine ball.
