    ps. Hydrogen is 10x more flammable than petrol and 20x more explosive. Neverthe less its lightness, dissipating it very rapidly and other factors mitigate many of its disadvantages. It requires a tank 20 degrees above absolute zero to store as a liquid or one capable of withstanding 10,000psi ie 700 atm. At 700 atmospheres in a 28 gallon tank a hydrogen fuel cell car would have a range of 250miles. (I think – these sort of figures always need checking)

    Tidal Wave Power generation unlike wind or solar, should be a total consistent source of power, come Hell or high water. There are a number of apparently obvious sites around the uk. There appear to be major technical though not insurmountable problems. The affect of effectively damming bays on the marine/ river ecology and the scenic eyesore engendered would surely even surpass the visual horror of wind and solar panel farms. Presumably we all agree nuclear is an accident (disaster) waiting to happen.  What does that leave – fossil fuel with co2 capture but apparently that is energetically impossible to achieve. So we continue down the path we are going. But do we or future generations want to live in a UK where the most beautiful but windiest parts of our island or the view out to sea are covered in turbines. Then there’s our green and pleasant land hidden under solar panels. Hows about a hold while we think about what we are doing and meanwhile spend our money on sea and river defences.
