Enhance ocean energy with static electricity
Water is heavy, so if you think about it, a moving ocean wave has a lot of energy. Scientists have a new way to use triboelectric generators to harvest this energy for ocean systems. (PDF) Triboelectric nanogenerators (TENGs) aren't new, but this new approach allows operation where the waves have lower amplitude and frequency, making traditional systems unnecessary.
The new approach uses a rotor and stator, as well as aluminum, magnets and, no kidding, rabbit fur. The stator is 3D printed in resin. The idea is to mechanically accumulate and amplify small low frequency waves into high frequency motion suitable for triboelectric generation.
The document contains a lot of information on wave modeling and the operation of triboelectric generators. One part of the build will be familiar to people working with resin 3D printers: the FEP film, which serves as the insulating part of the generator.
The document deals with a demonstration of the use of the generator to power an acoustic transmitter. The generator charges a capacitor, and when sufficiently charged, the system uses it to send data acoustically.
If you think using FEP film in a triboelectric generator is weird, try the tape. In fact, we've seen it done more than once.
