1. A system comprising:
- an energy source that provides an unregulated source voltage and source current;
a load;
a power extractor to transfer power between the energy source and the load, wherein the power extractor transfers power with a magnitude at least partially dependent on a continuously detected power change, and wherein power extractor output voltage and output current are unregulated.

Abstract
Apparatuses and systems enable power transfer from one or more energy sources to one or more loads. The input power from the energy sources may be unregulated, and the output power to the loads is managed. The power transfer is based on a dynamic implementation of Jacobi'"'"'s Law (also known as the Maximum Power Theorem). In some embodiments, the energy sources are selectively coupled and decoupled from the power transfer circuitry. In some embodiments, the loads are selectively coupled and decoupled from the power transfer circuitry. Power transfer to the loads is dynamically controlled.
