Experimentation of Synchronous and Variable Speed Small Scale Hydropower Systems

Creator:: Jackson, Elliott C.
Abstract:: Hydropower is the one of the oldest renewable energy technologies and is wrongly thought of today as having little room to grow. The opportunity for new hydropower capacity is immense through both technology advancement and run-of-river new stream reach projects. Despite the age of hydropower, a divide in opinion is...
