[00:00:02]Could fish robots protect our oceans?

[00:00:05]Meet Belle, the autonomous robot designed to seamlessly blend into the marine ecosystem. Belle glides through the ocean pumping water in and out in cycles. The design ensures minimal disruption to the delicate marine environment while Belle collects environmental DNA samples and high-resolution videos. The data collected [music] is crucial for studying the health and biodiversity of reef ecosystems affected by overfishing, pollution, and climate change. The energy fish, a small underwater power plant, generates green energy from rivers. The river current drives a rotor that creates electricity via a generator. A single energy fish can generate around 15 megawatt hours per year, enough to supply about five households. The Waste Shark is a robotic fish that chews up floating plastic waste in London's Thames River. The Waste Shark can remove the equivalent of over 22,700 plastic bottles per day. Which robotic fish do you think is most impressive?
