Small-scale Water Current Turbines for River Applications aims at giving a overview of the existing technology of water current turbines with a unit power output of about 0.5-5 kW. Water current turbines, or hydrokinetic turbines, produce electricity directly from the flowing water in a river or a stream. No dam or artificial head is needed to produce the small-scale power output. Several of the devices mentioned in the report may have application in tidal waters, ocean currents and manmade channels, but the scope of this report is limited to applications in free-flowing rivers. Reviews of the most common existing turbine technologies are outlined. The two most common small scale hydrokinetic turbine concepts are axial flow turbine and cross-flow turbine. The report is written by Kari Sørnes.
How to run an air-cooled Lister engine on Jatropha oil describes the process and experiences of converting a two cylinder air- cooled Lister diesel engine to run on pure plant oil (PPO). The engine conversion was performed as part of a renewable energy initiative on the coast of Kenya initiated by Norwegian Church Aid (NCA) in cooperation with Energy for Sustainable Development (ESD) Africa and ZERO. The report is written by Johannes Fjell Hojem.
