The oceans are a tremendous source of clean, renewable energy, yet the majority of this resource is located far from shore and the population centers that could benefit from the generated power. Tidal energy has been harnessed in various ways over the last few centuries, for both mechanical and electrical power generation. Presently, tidal energy is quickly becoming a viable alternative to conventional...
Polycrystalline diamond (PCD) bearings are ideally suited for use in extreme environments because of their extraordinary thermal and mechanical properties. Past use of PCD in process-fluid-lubricated down-hole tool applications, such as those in oil and gas drilling turbines, have proven them to be robust, long lasting, and rugged. Another harsh environment where the use of PCD bearings makes sense...
In the search for non-petroleum based energy, development of Marine and Hydrokinetic Energy (MHK) projects is proceeding at an exciting pace around the world. There are a myriad of devices (wave, tidal, thermal) and locations (metropolitan, remote, nearshore and offshore) being considered for development of ocean energy projects. One thing that they all have in common is that the biological resources...
