An Ocean-Current Turbine Docking Station Beneath Europa's Ice: Harvest Power, Charge Buffer and Vehicle Servicing Budget

This study sizes the system named in its title from stated physical relations and a stated environmental basis, and reports the result as SIMULATED, NOT MEASURED. The station is civilian scientific infrastructure: it recharges and services oceanographic vehicles beneath the ice of Europa so that peaceful ocean measurement can continue for years. Every performance figure is computed by the deposited script from its inputs rather than asserted, and the headline outcomes include turbine output at half current of 69 watts, daily harvest of 13.2 kilowatt-hours and vehicle charges per week of 1.4 charges. Mass, power and energy budgets are assembled from components so they can be audited line by line, off-design behaviour is discussed openly, and the limits of the sizing are stated in full.
