Inside a Biocoil water treatment plant

Interior of an experimental 'Biocoil' photobioreactor water treatment plant erected by Dr Stephen Skill in Nottingham, UK. It is a photobioreactor and uses Chlorella algae as a sewage treatment whereby the sewage acts as a nutrient for the algae, which in turn efficiently converts the sewage into algal clumps for easy removal. These can then be used as fuel for power conversion.
