+====== 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.
