About us

WaterLily is being developed by a Canadian start-up company, based in St. John's, Newfoundland and Labrador, that designs and manufactures power harvesting systems for the ocean monitoring industry. We have miniaturized the technology so that hikers, campers, paddlers and cyclists can utilize our 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. Our technology was designed to work for long periods of time in the harsh ocean environment and our prototypes have been successfully tested for over 1400 days in real world subsea environments.

Frequently Asked Questions

Technical (8)

What types of devices can I charge?
Any USB device can be charged with the WaterLily!
What if there is no river near by and it isn’t windy?
We will be adding a hand crank accessory on our store soon for emergency use. However, we wouldn’t recommend charging a device fully this way.
Can I mount it on a bike?
Yes! We are working on a bike mount. Available on our store soon.
Can I tow it behind my canoe or kayak?
Yes! We are working on a tow cable kit. Available on our store soon.
How does it compare to a portable solar panel?
The WaterLily is able to charge your devices on cloudy days and overnight. It is capable of charging for 24 hours a day. The power output is comparable to the portable solar panels on the market.
How does it compare to a bio-lite stove?
The biolite stove produces up to a peak of 3 watts of power under ideal conditions. This would be equivalent to a WaterLily in a river running at a speed of 3.4 km/h or in a wind speed of 34 km/h.
Can I use it in the ocean?
Yes. The components are all corrosion resistant!
What are the power output curves?

Why order now?
If you order a WaterLily now you:
  • Own a WaterLily as soon as they are available
  • Purchase it at a reduced price (20% off!)

Why did you do a pre-order campaign?
As a start-up company developing hardware a pre-order campaign makes sense. The amount of pre-orders we received helped determine the size of our first batch of units. We did not take any money up front but the number of pre-orders helped us finance the first manufacturing run.
