The Yoth cannon

If you had not noticed the Sirens believe Yoth is a frozen ocean planet.... They figure just because the water is frozen doesn't    mean it   can't be used. Siren technology though primitive to most sci-fi races and more advanced then real life have incredible electricity technology. And because their electrical technology is perfected with with water conduction and with out water conduction they decided with yoth reclaimed to pitch in with rebuilding the defenses for their friends. The weapon they build was child's play, and their first artillery ever to be meant for land combat. Microwave heating pipes melt the snow and suck it to 6 storage tanks which hold 17800 tons of water which is sprayed out a hose nozzle in a well focused jet of water with a range of 4572ft which hits so hard it can wash away cars spray down low flying air crafts with ease and peal the skin off the bones of unarmored infantry. The jet of water is complete with electricity using it as a wire that pack enough volts to melt a school buss in 20 seconds of direct contact. Their is at the request of a admirer of the weapon a infantry version small enough for a human to carry. It has a range of 185 feet and has enough voltage to explode a brutes heart in 48 seconds of direct hit.
