    The much lower current obtained with the graphite electrodes is expected because of the inert nature of graphite. However, with no supporting electrolyte and no apparent formation of products at either electrode, there is no evidence of what could be supporting this flow of electrons. An experiment by Stephanie C. Doan at the University of California investigated the phenomenon of solvated electrons in acetonitrile [5]. However, this system contains an iodide electrolyte which is inconsistent with the design of the CRS experiments.

    The much lower current obtained with the graphite electrodes is expected because of the inert nature of graphite. However, with no supporting electrolyte and no apparent formation of products at either electrode, there is no evidence of what could be supporting this flow of electrons. An experiment by Stephanie C. Doan at the University of California investigated the phenomenon of solvated electrons in acetonitrile [5]. However, this system contains an iodide electrolyte which is inconsistent with the design of the CRS experiments.
    Conclusion
    While most electrochemistry is preformed in the presence of a supporting electrolyte, these experiments were done in the absence of electrolyte in an attempt to discover new electrochemistry. According to mainstream electrochemistry, the flow of electrons in absence of electrolyte is no possible. However, these experiments show minute currents are possible without an electrolyte in pure acetonitrile. When using copper as the electrode a precipitate was formed. This was evidence that the system was able to generate its own supporting chemistry at a 23.5V potential. Though the quantities of product that these supporting reactions produced was too small for characterization, it was thought to be supported by a polymerization at the anode as shown by C. Bureau. This product was not observed with the graphite electrodes. This was likely due to the lack of current these electrodes produced.
