      @Stan Ervin The idea is plausible; however, the lower the efficiency of the plant the more toxicity is generated. I think that is where the problem begins because the benefit verse the compound detriments create a negative cycle. In the natural environment those conditions can be overcome, but in a dependent environment where the oxygen generation is a necessity, those negatives make a no go situation. I like your determination, there is definitely an answer somewhere.

      @Gw Builder Thank you for the input/clarification. My thoughts were leaning towards the use of ultra efficient low power consumption LEDs in a spectrum of sufficient fine tuning to obtain maximum O2 generation, perhaps utilizing arrays of Fresnel lenses. Just seems plausible. I feel like it could be utilized to oxygenate the vessel at least in a supplemental role with other methods that are currently implemented, even if a 25% level of impact is realized.

    12:45 "We call these Clinkers. Honestly I have no idea why we call them Clinkers" Clinker bricks are clay bricks that are too close to the heat source in the kiln. They come out overcooked, a darker color and usually misshapen and made a metallic ringing sound when you 'clinked' them together. They were rejects and discarded until their use was popularized during the Arts and Crafts architecture movement. Modern kilns are able distribute their heat more efficiently so they don't produce clinkers in the same way, but you can still buy bricks that are molded to give that misshapen and fire glazed look.

    • Eddie J. G.

      1. Out the tube as it pushes out the torpedo. 2. Torpedos have control surfaces, navigate themselves and are self-propelled. They don’t need a spin to keep them straight any more than the submarine itself needs one.

    So, while we are talking "science", you do realize that you can't just "hook" up anything to a nuclear reactor to get electricity........right ? A reactor merely generates heat energy in a primary loop, which in turn heats up water in a secondary loop to form steam for a turbine generator which is what creates your electricity.
