Upon reading my feature package on repowering the Welland Canal, one reader asked me if the 24 million gallons of water flowing through a lock is captured to generate power each time a ship passes. It was a good question given that not to put it toward that use seems like a terrible waste of massive water movement.
I asked my hosts about this when I visisted the Welland Canal on Nov. 9 at lock 3, standing next to older weir along side the lock. At the time, water spilled over that weir, but no power was generated. It was drainage only. The Taintor valves that control the in- and outflow of that 24 millions gallons run free of power generation, probably because the 24 million gallons has to enter and exit in 7-10 minutes to quickly dispatch the vessels. Adding generators would presumably slow down the flow.
However, the canal’s U.S. and Canadian overseers signed an agreement last year to build three hydro plants that uses existing weirs to capture "run-of-the-river" water that spills over them. The weirs handle the overflow water that does not pass through the locks. Why didn’t I think of that — after 75 years of operation!? Each power station will produce 2 megawatts and in together promises to power 5,000 homes, so sayeth the canal’s overseers.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
