How does it work?

This project works on growing algae instead of seeds. It is a system consisting of a combination of a photobioreactor and a system growth chamber .I worked on how to improve the previous solutions to make the most suitable solution for this problem .At first, I had to think about what is most suitable crop we can produce. After reading resources of NASA and searching , I found that algae is most suitable for cultivation in space. It does not need soil. It is also able to face radiation and bacteria due to its presence in alkaline media. It also contains a very large amount of proteins and vitamins. It can also be dried easily and used for long periods. So, I made my work up to Mixing algae cultivation and using a system APH . With the help of the photobioreactor, we can grow algae, and here comes the role of mixing. The photobioreactor can be placed inside the structure of a system APH. Which helps to reduce the number of sensors as the photobioreactor needs a specific number of sensors and they are PH Sensors ,Temperature sensors ,Light sensors and O2 sensors .In addition to the presence of a part dedicated to the control, and hoses to enter the carbon dioxide, which will be the main source of the astronauts on the ship, in addition to a small pump on the top of the water bowl containing the algae to stir it in the bowl to ensure a good distribution of light and avoid the formation of bubbles where gravity is generated. And an air filter On the structure of the system to ensure its filtering before entering the hoses connected to the algae pot to absorb carbon dioxide. I think making an algae bowl out of polypropylene will do the trick.

Achievements:

Achieving an easy and advanced system from the previous solutions and reaching the optimum crop for its cultivation and having a positive impact on the health of human structures

What tools I have used?

In developing the project, I used NASA data and means to access previous systems, and some research in the field of biomass, algae cultivation and methods of cultivation using the photobioreactor.

Data from NASA was very useful and inspiring to think outside the box and find ideas and solutions characterized by creativity and non-observance, especially as it provided full information about their previous efforts which are:

1. VEGGIE.
2. APH.

• It was really fun and useful Hackathon Journey.
