Experimental evidences of electro-thermal ablation acceleration of water

We report the first demonstrations of driving water of about 1000 grams by electro-thermally ablated gas pressure in a cavity with a single exhauster. A blob of water was shot into the air with a shooting angle of about 45 deg, and the flight velocity observed was about 13 meters per second with the capacitor (28μF) charged up to 10 KV. The discharge sound was almost suppressed by the water blob loaded in the chamber possilbly because the energy of sound was dissipated into the water blob. The application of this ablation water driver to ship propulsion is also discussed. (author)
