Sustainable Sewage Plants
Engineers from Stanford University came up with the idea of rocket engine wastewater treatment plants and say the process could also be used to clean up nitrate-contaminated groundwater under fertilized farmland.
Implications - Brian Cantwell is the professor who has created the rocket engine wastewater treatment plants. He wanted to use nitrous oxide as an energy source that was emissions-free. This is an incredible development by a brilliant man and it could have vast implications for the environmental movement's cause.
