Greenheatman You appear to be versed in how to get KGs to equate to the mass of CO2 answering some of the imponderable nature of how we should go about turning this world back to some sort of energy equilibrium. As such could you please direct me to where I can find a simple way of working these sort of things out for myself without the need for another 5 years of largely wasted education. Your comments are well observed, but I guess this would be my point; we won’t get 24/7 secure energy from the Pentland Firth or any other marine resource without vastly more investment than is currently being committed. There is absolutely no doubt that this resource is both technologically and theoretically able to provide such a security of provision. Ask Bill Mowat he knows more than most. I would say that this industry is still at the 50-75% stage of spending money at the lets meet and talk stage, and many bums are being warmed on seats without any actual contribution to moving the technology forward. Big brother in our world is I am afraid a conversationalist first and an entrepreneur twenty one skills sets below . The Pentland Firth Energy leasing round has just been put back again to Feb, 2010, a delay of 8 months, and the rumour is the leases will be awarded to utilities companies and not developers. The reason is simple the government is now in bed with Crown Estate to get the utilities to pay for the costs of the power line which must be put in to service 700 -1300 MW of planned out put. That this cable will be too small if the scheme works and too costly if it doesn’t has the potential to strangle this project in Caithness. There are of course others equally likely to be affected, the loss of the Caithness Hub concept will be the first to falter as partnership is scrificed at the solicitors contracts door. Crown estate are in it solely for the carve up, nothing new there then, as landowners they understand only rent for land, even if that land is below the sea and the domain of fishes and kelp. The people who live in the area’s of Caithness and Orkney can immigrate to better climates as they wish for little comfort can be trusted to their benevolence. Placatory words and high aspirations will be expressed but the papers will be in the safe and the beads will be hanging like lead weights from the populations necks. I might have been able to Trust an alliance of Developers and Scottish government being that their would be some purpose common to communal poverty. You worry about the ROC’S and carbon credits up for grabs, I worry about living in a world where these big boys set the agenda's for which most of us always have to pay. Look no further that the current financial bail out which we are now all being saddled to pay. Never mind I hear things are looking up in China, there may even be a democracy of sorts in the next hundred years. Seams to me they can get the business done, and damn the consequences, capitalists today...you bet.
