This is my contribution to the blog. In this Ted Talk, Jonathan Trent talks about his OMEGA (Offshore Membrane Enclosures for Growing Algae) project. The goal of this project is to farm micro-algae that would produce energy by feeding on the wastewater from cities. The process also utilizes the consumption of carbon dioxide and solar power. In today's world where there is a growing need for alternative energy, projects like Jonathan's are increasingly important.
