Te shift to electric propulsion signiantly reducles thee carbon footprint of personal submarine operations. A typical two- hour dive with a 40 kWh battery consumes routly 15 kg of CO conquigent (assuming grid charging), compared to 50 kg for a diesel generator run. Moreover, oil extra s and exit fumes are eliminated.
