This Author has claimed since the 1070s (yes, I am that old) that the United States needs to develop the technology for Energy production from Water--oceans and rivers. The failure comes mainly from a conceptionalism rooted in huge structures and massive machines. It is the wrong approach.
Conceive of lines of Generators set up like ferries. Basic barges run lines across major rivers (equally useable in oceans), pulling them up and laying them down periodically for maintenance and cleaning. Spaced along these Lines would be generators made to lay along the bottom like Crab traps to prevent fish mutilations', connected at the origin point to a trunk line to draw off the electicity. Every barge could run about 15-20 Generation lines, connecting to the trunk lines by easy connection Twist attachments and Safeties. The entire system must be designed for simplicity, maximization of pwoer generation, and periodic maintenance service. Simple and Cheap is the key?
Elsewhere, the Institute of Supply Management index is down to 54.0 in July, a drop of some three points (score of 50--economy is supposedly still growing). The trouble here lies in the fact that the ISM index is a fairly solid forecaster of trends. The economy is definitely slowing, but by how much? lgl
