====== Race Way Pond - Cultivation of micro algae ======

//Algae are "lower" plants that live in water.//

Algae can be very small (microalgae) and consist of only one cell, but they can also be huge
and up to 100 m long (macroalgae, especially brown algae). Like "higher" plants, they also
produce oxygen and therefore contribute significantly to the binding of atmospheric carbon
dioxide. Algae can be found in fresh water, salt water and also in moist soils. Millions of
years ago, blue-green algae or cyanobacteria helped to produce oxygen in sufficient
quantities for life to develop. In addition to the food and cosmetics industry, algae can also
be used as fertiliser in agriculture. However, algae, especially microalgae, can also be used to
produce energy (biogas, biodiesel, bioethanol and hydrogen). Algae can be cultivated either
in natural ecosystems, in aquacultures or in photobioreactors.

Compared to land plants, algae have a growth rate up to 30 times higher. Algae grow so fast
that in industrial production, one third of the biomass can be harvested every three days. In
photobioreactors they can be produced in a particularly space-saving way and under
controlled conditions. There are different designs for this purpose; some of them are
cultivated in kilometre-long tubular systems. These have the advantage that the algae
receive light from all sides and, compared to open systems, are protected from
environmental influences.
