the energy tap can be used for a power collection point or a battery charging point for a cable. the energy tap is placed between two cables. ( like this: :Cable: :MFE-Transmitter: :Cable: ) when a battery is placed in the energy tap and a power source is connected to the cable, the energy tap will re-direct all energy flowing through the cable into the battery. the energy tap doesn't store energy, it just acts as an energy collection point for a solar flower or something. finally, there could also be upgraded energy taps that could charge a energy crystal.
