This system collects urine and hot composts human excreta in a dry-composting toilet system for eventual use on the community's organic gardens. The system design reduces the need to access municipal water, sewer, and electrical infrastructure, enhancing emergency preparedness. It conserves an otherwise wasted nutrient flow, and safely produces a valuable compost. The system consists of urine collection vessels, multiple portable collection containers for excreta, toilet paper, and additive, and a compost processor. Urine diversion has allowed the community to reclaim nitrogen and other nutrients otherwise lost in conventional sewage systems, resulting in l...

UPS-type hydraulic hybrid ground fleets can be greener by optimizing energy use in these low-emission vehicles, since stopping, and starting is key to saving fuel in these types of vehicles. With a residence time of only 78 days in the troposphere after combustion, more economical ethane (C 2 H 6) can be a greener bridge in the transportation sector. Ethane can act as an alternative fuel stock to expand this vehicle truck option, provide an oil saving solution, and reduce global warming emissions without drivers changing their driving habits. This is the best use of ethane adding the highest value using the simplest technology. In 2015, an ethane bi-fuel field trial was conducted in Jewett, Texas, USA using a modified fuel injection system in a Ford F150 4.6L Triton pickup truck. Emissions results returned 2 ppm particulate matter, 0.00% Carbon Monoxide (CO), 0.01% Carbon Dioxide (CO 2), and 20.79% Oxygen. Performance results returned torque slightly better than gasoline, and fuel injection time slightly slower than gasoline, providing better combustion. A higher, 9% increase in miles/GGE (gasoline gallon equivalent) efficiency versus gasoline was produced, resulting in 30% less CO 2 /mile on the same vehicle compared to gasoline. We are proposing a follow-up test. This test will show the ethane truck functions well in colder conditions, heavy traffic, that it meets or exceeds California's air pollution laws, and that the test is repeatable. This paper will provide some background on ethane production and usage, and assert that it constitutes a better fuel system for the entire United States.
