bhackett, 3/10/2019:

My plan over the next several months is to conduct some experiments to get a better understanding of how well seawater electrolysis works in practice. This should help assess both the usefulness of electrolysis for directly alkalizing water, and the theoretical effectiveness of the Biorock technique. My main questions:

  • What is the rate at which electrolysis occurs with different cathode materials, voltages, and distances between electrodes?
  • How effectively can electrolysis alkalize a small (3m x 3m or somesuch) and isolated body of water within a lagoon?
  • How quickly does accretion occur with different cathode materials and voltages?
  • What is the electrical conductivity of accreted and attached coral fragments?
