A device for powering a load from an ambient source of energy is provided. The nanoparticles have a plurality of fibers, wherein each fiber is in contact with one other fiber and each fiber has a length of between about 1 nm and about 5000 nm. The larger size may allow for more features, may make it easier to dissipate heat, may make the circuit cards easier to shield, andor may allow for the use of larger and less expensive components on the circuit cards. Access controls further enhance the effectiveness of the methods and structures to enable multiple simultaneous organizational schemes and selective sharing of objects. The automatic increase in current compensates for the gradual decay of the light emitting diodes over time, thereby allowing the light emitting diodes to maintain a constant illumination for the lifetime of the appliance.
