A Welsh outfit named Swanturbines are flogging at a renewable energy meme that’s been ‘in development’ since long before I was born – tidal power. They’ve got a new super-simple turbine design that they believe will be easier to maintain, as well as more effective at harnessing the abundant energy contained in the UK’s mercurial coastal weather. Inevitably, and just like all the other designs before it, this will get nowhere unless someone decides to throw a lot of money at it – and seeing as the British government are still very sweet on nuclear, that’s going to have to come from the private sector. Paging Mr. Branson; you are needed at the beach.
