"Engineering Professor Jonathan Scott, PhD student Mark Jones and Summer Research Scholarship student Wayne Crump are looking at the best way to harvest power by separating electrical charge in water, without moving parts"

"“If we can harvest energy from the water we're metering then we remove the need for batteries, which is what current smart water meters need. Not only will this prevent thousands of batteries ending up in landfills each year but also save having to replace them, a much greener alternative.""

Additional: Few domestic smart water meters have been deployed in New Zealand. Tauranga City performed a small trial recently.
