Users

The target group of our device would be people who live close to either oceans or rivers, or areas where it is known that floods are prone to occur. Although The Netherlands is excellent protected against the ocean, it is still below sea level, making it a dangerous area if floods were to occur.

Therefore, everyone listed above will benefit from having something installed that could reliably warn about incoming floods. However, even if you don’t live in one of the mentioned areas, you can still benefit. This is because floods can cause major damage to the economy of a country, making it generally harder for others, or other surrounding countries as well.

To summarise, the most important stakeholders include:

  • The general public: benefits from the increased protection
  • The government: Increased chance of economy stability
  • Investors: Due to implementation, they get higher returns (or something, I'm not an investor). They may also have some say in the development process.
  • Inventors/designers: Can sell patents for money, or design further. They also directly control how it operates.


State of the art

Water quality checks, focussed on sensors:

Swarm of robots:

Detecting micro plastics, focussing on the chemistry part:

Generating energy:

  1. Tidal current power generation: https://link.springer.com/article/10.1007/s40722-016-0044-8 + https://www.sciencedirect.com/science/article/pii/030142159190049T - There are different types of tidal current generators: turbines (multiple types), kites and hydrofoils. Out of these 3, turbines are the easiest to understand, however, they either require too much space (axial-flow), or don’t generate enough reliable power (cross-flow). Furthermore, the materials could get damaged by prolonged contact with water, reducing the lifespan of anything operating in the water.
  2. Wave energy generation: https://www.sciencedirect.com/science/article/abs/pii/S1364032115003925?casa_token=CVv0TFwNB7EAAAAA:4Y-xywxZlAy8BZ6r8pWrPb8Awjj4AhK5sI4MiIz0dBDEToEbmcoQwQ-DvR6aurkkL3MSNqI67k4M + https://aip.scitation.org/doi/full/10.1063/1.4974496  - Either linear or radial generation. For us, linear would be the better option as it requires less space (but is, of course, less efficient). This generation would be done by means of moving multiple permanent magnets around, creating a moving magnetic field, inducing a flux through a coil, which in turn produces current. This method will, however, only work when waves are high enough, and may, therefore, not produce enough power for whatever we may want to install inside our aperatus.
  3. Solar power generation: https://www.sciencedirect.com/science/article/pii/S2214785318312665 - may be possible, however, it would mean that there is a large possibility that the device would not be active for large periods of time. Further, life spans of PV cells are not extremely long, and are easily damaged, making it not the best solution for ocean power generation.
  4. Triboelectric nanogenerators: https://www.sciencedirect.com/science/article/pii/S2211285519304628?casa_token=2Tpy27NOQPAAAAAA:ujdMrGEREH3dbh4gfeWgOvj3Wj5Br3X2cEBS-_Dg5jG00sTSDGgrxvZkc4G2e98LYs_pvBX90yVT + https://www.sciencedirect.com/science/article/pii/S2211285514002353?casa_token=Ow53wafsXIkAAAAA:D4sDZMP-x4ull8nveIxces-zSmaTDom9e4ERPpAaqBPiYtD4OT14B4j5SPJdqJKm6GjanENsUT2n - The generation of energy created by rubbing two objects against each other. The rubbing part will then occur due to the mechanical energy provided by the ocean waves.

Conclusion: In general, most of the solutions regarding waves or movements take into account the fact that the generation is able to take place on a fixed point. If we would use something that floats in water, this may become an issue. Therefore, although it is not the most optimal, PV energy generation (solar panels), seems to be the best solution.

Smart Buoys

During the search of the state-of-the-art for smart buoys, many of the articles found consisted of potential prototypes for different varieties of buoys that were deemed to be 'smart buoys'. Smart buoys can be considered to fit in all the previous. This section will briefly discuss some potential implementations and key questions that would need to be asked when considering a 'smart buoy', that does not go into as specific topics as the previous headings.


First of all, from the following article https://ieeexplore.ieee.org/abstract/document/9389065?casa_token=v1iLJdDU9aQAAAAA:hti71IRV6XXgflmDxqO0QJ1bzK-giHRImvC4JeY6JnXn2hj0Z45GVwvBPukmVMOL1-gyF9qkvQ, multiple questions were seen to be important for the designing and making of smart buoys and even buoys in general. The most important question that can be deduced is in what sort of body of water will the buoy be deployed in. For example, Oceans and Seas are more unpredictable and destructive due to being large bodies of water, whereas a lake is usually much calmer, even in more extreme weather conditions. Following this, another question that was seen is in what sort of depth would the buoys be deployed in. This can directly impact some decisions that would be made, such as connections for swarm behaviour. For example in shallower, it might be a possibility connect the buoys using wires, but in deeper waters it might be better to connect them wirelessly. This would then also impact what would need to be put on the buoy so that it would function as intended, such as what hardware and software would need to be used, and how would it be powered, which is looked into in the Generating electricity section.


This following article showed a potential way a 'smart buoy' could be implemeted as a state-of-the-art idea: https://ieeexplore.ieee.org/abstract/document/4099173?casa_token=KUV7FHj5NFUAAAAA:_IQbjLXYaynpEfAHVrqD5MLHcfGcV4nyolt6auvFSZZQ7zUhhcor-JBIMuTrrfhW9gOqmG4sUA. The main concept of the prototype mentioned here is that a 'smart buoy' could be used in an auto aligning fashion and the reason that this might be important is because many buoys already existing are used to guide ships with some used to moore smaller ships away from shore. But since the seas and oceans can be quite unpredictable, harsh weather can sweep away buoys from their initial location which can affect how ships and boats would move around.
