this new product, big like drones

a floated board, with an onboard solar panel, battery, and ionizer into the water.

pool, rivers, wetlands, oceans,

improves the quality of the water

if you make plenty of them, it wont seem like a manky old universe

theory is it would slowly improve wetlands, rather than sick smelly wetlands, you have higher functioning wetlands.

in the news is an ionizer device that can make drinking water from seawater, thats great!
