I have developed a system called SSTCS-"Synergistic Sustainable Tumble Culture System" that can take eutophic water from point source pollution from effluent or no point pollution that ...

Summary There are a great many ways to produce biofuels, and a vast and fast-growing amount of literature on the subject. Ratios of energy returned on energy invested (EROEI) are typically in the range 1.6-6, with some particular authors putting corn ethanol at below 1.0, and others putting ethanol from wheat straw at around 35. All the figures here are ...

Fuel consumption is typically 70-90% of a vehicle's lifecycle energy consumption and greenhouse gas (GHG) emissions, so there are lots of circumstances where upgrading to a significantly more energy-efficient vehicle makes a lot of sense. See, for details TRL VR6 and The UK Automotive Sector: Toward Sustainability. If the vehicle being replaced gets a very ...

I looked into this question a bit today and it seems that the industry is not yet mature enough to determine a narrow, consistent range for the energy in to energy out (EIEO) ratio of biofuels for aviation. "Are Advanced Biofuels for Airplanes Ready for Takeoff?" (Scientific American, May 2017) This excellent SA piece discusses the industry forces behind ...

So when looking at a car you may want to take into account your ...
