Another Thought Which Has No Words…… other than Stupid

 

I’ll give you the story and my thoughts afterwards. 

A new genre of electric power-generating stations could supply electricity for more than a half billion people by tapping just one-tenth of the global potential of a little-known energy source that exists where rivers flow into the ocean, a new analysis has concluded.

A report on the process – which requires no fuel, is sustainable and releases no carbon dioxide (the main greenhouse gas) – appears in ACS’ journal Environmental Science and Technology.  Menachem Elimelech and Ngai Yin Yip explain that the little-known process, called pressure-retarded osmosis (PRO), exploits the so-called salinity gradient – or difference in saltiness – between freshwater and seawater.  In PRO, freshwater flows naturally by osmosis through a special membrane to dilute seawater on the other side. The pressure from the flow spins a turbine generator and produces electricity.

The world’s first PRO prototype power plant was inaugurated in Norway in 2009. With PRO appearing to have great potential, the scientists set out to make better calculations on how much it actually could contribute to future energy needs under real-world conditions.  Elimelech and Yip concluded that PRO power-generating stations using just one-tenth of the global river water flow into the oceans could generate enough power to meet the electricity needs of 520 million people, without emitting carbon dioxide.  The same amount of electricity, if produced by a coal-fired power plant, would release over one billion metric tons of greenhouse gases each year.

This is ….. you see there’s actual flow …. but….  the reasoning would be objects in the way…..   you see, pressureretarded osmosis is ….  

I can’t.  This isn’t fair.  What they should really do, is dig a great big giant ditch with great big bowls of earth dug out on each end, fill it with water, then use a windmill to push it up and down and make energy that way.  It’s way better than traditional hydro.  You learn this through…….. osmosis!  Smile

    LMAO!

    Need one of those to run our new desalination plant in Sydney. This is the one which hasn’t made any useful water because all our dams are full and overflowing. After all if you can make power from pressure retarded osmosis and fresh water from revere osmosis using that power what could possibly go wrong?

    Can’t do it in Melbourne since completion of the desal plant they are building to save the city from the drought has been delayed for two years because of all the rain they’ve had.

      Bruce:
      As soon as they decommission the plant it will be time for another drought.
      What was the description of Australia, that was given it in the late 1800s? The Land of Droughts and Floods? ๐Ÿ˜‰

      • Bruce says:

        The sad thing here is in Melbourne the left wing government cancelled the Mitchell River dam proposal then built this vastly costly lemon instead.

        Here in Newcastle the left wing state government cancelled the Tillegra Dam proposal just before the state election and built the currently useless desal plant in Sydney. We already have a pipeline which goes half way to Sydney (its only 100 mi from Newcastle to Sydney) and sell water to that area.

        So the country is down something like $30 billion because of political madness and greenie fixation with supposedly evil dams. I just don’t understand, but I do understand my quarterly tax bills.

        So….. more than one group of people did this? On purpose?

        • Bruce says:

          The same mainstream political party did it in two different states. Sound familiar? That party, the ALP, has since been unceremonously turfed out in state elections in both states Vic and NSW (and also out of Qld recently), but the water producing dinosaurs are tightly contracted so shutting them down would cost as much as continuing to operate them. This was done on purpose.

        • miked1947 says:

          Here we call it a Golden Parachute clause. It costs more to stop the wasteful operation than it does to continue wasting money to have it do next to nothing.

          It’s a mad, mad world.
