A photobioreactor is a closed or semi-closed system in which light and nutrients are supplied to the system in an attempt to maximize algal biomass. Nutrients can be in the form of pollutants, so the sculpture can facilitate bio-remediation. It can also use CO2, reducing greenhouse gases.The algae can than be used to generate biodiesel. In this proposal the biodiesel could be used to run the machinery and vehicles that maintain the park. These photobioreactors are designed in a sculptural manner to add an eye catching feature to the park setting. It consists of an aluminum carriage which has a continous spiralling tube that cascades from top to bottom. The work could be lighted at night to create a beautiful evening experience powered by a solar array and batteries. The bioreactor towers are attached to a harvesting machine which would extract the algae biomass. Examples of a hypothetical installation. Buy your custom designed bioreactor sculpture today!
