Before, he gets a permanent ship made, he should wish for a piece of ”Unmanned Rock” from HunterxHunter. A single bead of unmanned rock can generate 20 kilowatts of electricity a day when placed in water. According to google, an average Australian household up to 18 kilowatts of electricity a day. So, you can use the basketball sized (or bigger) ”Unmanned Rock” to be the ship’s power source.
