    There is a danger we get too hung-up on “efficiency”, whereas the important issue is one of benign sustainability.

    I’m not overly convinced by the fuel cell, which appears as the weak link in your schematic.

    Yes we have. Time.
    That is why it is a good idea to site stations in relatively remote areas, design them well, and run them exceptionally well. On the whole, Western European and American reactors have a remarkably good record.

  3. Surely though “sustainability” ;) requires a measure of efficiency too?

    Is it even possible to be inefficiently sustainable?

    By the way confused about your last comment re fuel cells? What are you not convinced about - their worth as an energy conversion device or their depiction in the diagram? Please clarify.

    Where is this remarkably good record. Think you need to have a hard look at the French Nuclear reactors held together with sticky plasters with forced outages on a daily basis. Its only the fact that the fleet is ultimately owned by the french government that its not in the press every day but even the government cannot hide the problems there having with there new builds. ie poor quality, over budget, long delays.

    It only takes one accident to make large areas uninhabitable, I'm a supporter of nuke power but it does have its dangers, why we don't rely more on river and tidal power is beyond me, of it might be there isn't enough money to be made by big corporations

    What your forgetting is that we all generate methane every day its just normally out of sight out of mind.

    The technology exists to process our waste and directly inject into the gas grid as at Minworth below.



    Obviously farm AD plants can do the same so you get a baseline of renewable methane. This can be enhanced by excess power producing Hydrogen and injected into the gas grid with the methane upto 50% would equate with the old coal gas limits. Finally synthetic gas can be made from the CO2 capture at the gas generating plants. The existing gas grid is the energy storage facility for renewables which is currently capable of 15 days supply without any wind or solar. This really needs to be increased to 6 weeks but whilst supplies from Norway are relied on I cannotsee that happening.

    Tidal Energy, Wind Energy etc is the way to go

    Totally agree with river and tidal but its the EA which stops river projects and government with tidal. Maybe with Mays declaration tidal might be back on the agenda.

    As an example; the human body is reckoned to be only about as “efficient” as an internal combustion engine, but being part of the carbon cycle it doesn’t matter, as it all works out in the end. The Hydrogen cycle could potentially be similar.

    Re the fuel cell; perhaps I’m not understanding the schematic, but aren’t the percentage figures relating to efficiency/losses. Perhaps there’s a better way of utilising Hydrogen.

    And just think, by electrolysing sea water we’d be combating rising sea levels, and all that water generated by burning the hydrogen could be used to irrigate the deserts. It’s a win win:ROFLMAO::ROFLMAO:

    Why would you do that when you could just export the fresh water prior to it going back into the sea.

    The post was somewhat tongue-in-cheek.;)

    Shame I thought I had a new outlet for all my water going down my streams rather than giving it all away for free to United Utilities.

    Engines don't have to burn fossil fuel, Can't they can burn renewable fuel at the cost of being less efficient?

    Is there enough flow to power something?

    Certainly is.

    They do have to burn fossil fuel for road use unless the government give an exemption. Have been over 7 years trying to get a renewable fuel licenced for road use but the government by persuasion I presume from the oil companies intend to keep a lid on it despite increasing the efficiency of the engine and reducing NOx emissions to virtually zero.
     
  20. The death toll from nuclear power is fudge all compared to other methods.
