Tide is a vertical photobioreactor designed to emphasize the movement of the water that is necessary to grow spirulina algae.

It is specifically designed to be inserted inside a village built on the moon, where astronauts could spend up to 6 months. Spirulina, thanks to its extraordinary nutritional properties, could become a fundamental element for the nutrition of the inhabitants of the moon. Because of the potential that these algae have, this product aims to grow a small batch of them for personal consumption by the astronauts.
