Recharge with water and wind energy

(www.energyharvestingjournal.com)

Seaformatics’ Waterlily is a portable turbine that can harness the power of both wind and water. Weighing 800g the waterlily is light and measuring 180mm by 75mm it is small and easily transported or taken camping, kayaking or cycling. When harvesting power from water the minimum flow required is 1 km/hr and flow for peak power output is 7.2 km/hr, although Waterlily can work in flows up to 11km/hr. The device can be submerged indefinitely up to almost 11 thousand metres. The components are all corrosion resistant for use in the ocean.

When harnessing energy from wind the minimum speed required is 10.8 km/hr with peak output at 72km/hr but the device can work in winds up to 90 km/hr. Any USB device can be charged with the Waterlily and Seaformatics will be adding a hand crank accessory for emergency use. In the future the device will also come with a bike mount and tow cable kit for towing behind a car or kayak. Waterlily is being developed by Canadian start-up company Saformatics based in St. John’s, Newfoundland and Labrador, that designs and manufactures power harvesting systems for the ocean monitoring industry. Seaformatics have miniaturized the technology so that hikers, campers, paddlers and cyclists can utilize the patent-pending, low-speed turbine while enjoying the outdoors. The four founders of the company are engineers who developed the technology as part of a 6 year multi-disciplinary engineering research project at Memorial University. Their technology was designed to work for long periods of time in the harsh ocean environment and their prototypes have been successfully tested for over 1400 days in real world subsea environments.
