Jellyfish are fascinating creatures that use bioluminescence to attract mates, distract prey and capture predators. They are expected to have a short life span of 1 year and usually bloom in spring or fall. Some species also bloom more than once a year. Jellyfish blooms have been seen to be on the rise since the 1980’s and much of it is contributed to human impact on the environment, which led to global warming and eutrophication. The blooms are also on the rise due to fishing activities and aquaculture. This rise in jellyfish population has negative effects like reduced tourism, clogging of thermal power plants and diamond mines, changes in sea beds and marine ecosystems. Some researchers predict, that at the current rate of bloom, the population will continue to grow for another 100 years.
In my project, I would like to focus on the problem of this problem, and imagine a future where only jellyfish cover the aquatic life and are the only available resource. So I would like to create an iteration of how jellyfish can be used for multiple purposes. Since jellyfish cannot be kept in regular fish tanks, and we’re out of most resources, the jellyfish is biomimicked to be kept in a regular fish tank.
Jellyfish would be the source of many things like:
- Power supply
- News update transmission
and so on.
The ultrasonic sensor would be the inducer of all of the above. Blocking the ultrasonic at a certain distance would make run the servomotor, which would make the jellyfish move vertically up and down. The servomotor would resemble the production of power supply. The LED on the jellyfish would change color over a few seconds, depicting that the required amount of power has been generated and stored in the jellyfish.
There would also be a clock that moves around the tank. When the hour hand is before the ultrasonic (the distance being closer than required for power generation), there would be an update on the website (operated from the phone).
The update would show the following information:
- Current time of the day (imagining time is difficult to tell since its perpetually dark due to pollution)
- Latest disaster or issue identified around the world
- Home temperature status
- Outside weather status
- Stage of jellyfish bloom (imagining every household has to manage jellyfish aquaculture to create their food)
- Quantity of edible jellyfish available for current consumption
