Okay Imma start breaking this down.
Firstly, element 119: You basically hit the nail on the head. Scientific consensus has postulated that it will likely, yes, be an obscenely radioactive and ridiculously reactive alkali metal with an absurdly low half-life
Algae: I've had some similar ideas regarding this and other marine agricultural solutions. I actually have some ideas laid out for oceanic development.
Laws of aerodynamics: Actually those are the laws of THERMOdynamics. Aerodynamics only deals with gasses
Don't have time to look at the rest rn, but it looks cool! If ya ever want to brainstorm ideas together, feel free to reach out on Discord at AquaSpider#7823.
