B.A.C.S. Proudly created with Wix.com

We want to say thank you to our coaches and mentors for helping bring out the best of us. We would also like to thank all of the Papagayos who kept us motivated to continue our scientific work. Thank you NSTA and Toshiba for giving us an opportunity to demonstrate our creativity and scientific literacy through ExploraVision.

Present Technology

  • Researchers at Mote Marine Laboratory and Aquarium, located in Florida, created an ozone treatment to clean their animal hospital pools.

  • They used an air compressor from a household air conditioner as a motor to power a vacuum to suction the infected water into a chamber.

  • The water would then be sprayed with ozone to dissolve the Karenia Brevis. The clean water is then released back into the canal. 

  • This system is the only current technology that is efficient in cleaning algae blooms.

  • Even so, this present technology is not an ideal solution because it is not mobile and it can only clean small bodies of water.

B.A.C.S.

Our Invention

        As a potential solution for the future, we invented B.A.C.S, Biomimicry Algae Cleanup System to help clean up toxic algal blooms like Karenia brevis.

 

      B.A.C.S is a robot

modeled after a bottlenose dolphin through biomimicry. We chose to use a bottlenose Dolphin because of their form of communication. In addition,

dolphins are common coastal animals with very few natural predators. Dolphins are also at the top of the food chain, and fish will be afraid of B.A.C.S. and swim away.

 

       B.A.C.S will use the same ozone treatment that Mote used to clean the water. Furthermore, B.A.C.S will be capable of making its own biofuel made from collected algae from the cleanup process.

The Process

     B.A.C.S. will use a motor to power the vacuum to suck up the contaminated water. The algae will then be separated from the water. The water will then move to a chamber to be cleaned with ozone.

      After the water is cleaned it will travel through a tube and will be released back into the ocean. The algae will be processed in two different stages in order to be turned into algae biofuels.

       The Supercritical Fluids Method will be used to extract the lipid oil from the algae.

 

       The oil will then go through transesterification where the necessary alcohol will be added. The oil solution is then refined twice, eventually removing the glycerin. The end product is algae biofuel.

Consequences

     The first positive impact will be the reduction in deaths and illness of aquatic organisms, coastal birds, and even pets  that occur due to infection from algal blooms such as red tide.

 

      Another benefit is the reduction of negative health effects on humans living in or visiting the coastal areas affected by the toxic released by the algal blooms.

 

      The production and use of biofuels will make the biggest impact on the recurring red-tide algal blooms by reducing contamination.
