Abstract: A method for receiving animal waste from animal confinements or other concentrated animal waste sources and for converting the waste into a usable form is described. The waste contains both liquids and solids. The method includes separating the liquids and solids into separate waste streams, controlling an amount of moisture in the solids waste stream such that the amount of moisture in the solid waste stream is compatible with a selected energy conversion process, and feeding the moisture controlled solid waste into the energy conversion process.

Abstract: A roadway interchange for a roadway system is described which includes at least one traffic lane approaching and passing through the interchange from each of four directions. The roadway interchange includes a curved portion for each traffic lane passing through the interchange and at least one exit lane for each direction of traffic lane. The exit lanes provide a substantial right turn for traffic wishing to change a direction of travel to a direction substantially similar to a right turn. The roadway interchange also includes a merging area for traffic wishing to change a direction of travel to a direction substantially similar to a left turn and at least one second exit lane for each direction of traffic lane. The second exit lanes pass either under or over the traffic lanes in which travel is desired and changing in elevation to merge with the merging area.
