Abstract: Lignocellulosic material such as agricultural residues, e.g. straw and bagasse, can be converted into products that can be easily transformed into feeds, fuels, and soil improver. The reactor described herein affords simple efficient transformation of lignocellulosics to acidic organic liquid, heat, and ligneous sludge residue in a typical use. The acidic organic liquid may be used as the main component in the production of SCP, the heat may be used subsequently for heating or drying, and the ligneous sludge, when dewatered, used as soil improver or as fuel.

Abstract: A wave-propelled marine vessel is advanced by rising and falling water currents acting on pivotable fins located on submerged outer fin assemblies, and on other fins on a submerged central fin assembly. The outer fin assemblies are adjustably positioned to be integral wave lengths apart to maximize forward propulsion efficiency.
