The legal framework for offshore wind farms: A critical analysis of the consents process

The impact of the legal framework for the consents process on the rate of development of offshore wind farms in England, and the achievement of targets for renewable electricity generation have been reviewed. From the literature and consulted stakeholders it was found that the complexity of the current consents process has adversely affected the rate of development and the achievement of renewable energy targets. Future projects will be subject to a different legal framework for consents, under the Planning Act 2008 and the Marine and Coastal Access Bill. From a comparison of process diagrams for the current and future consents processes, it is concluded that the future process should be an improvement. However, uncertainties remain about the detailed procedures and operation of the future consenting authorities. The capacity and capability of key stakeholders to meet their obligations have implications for the time frame for the processes of applying for, and the granting of, consents. Furthermore improved engagement from developers and clarity about the role of local authorities are essential if progress is to be made. The need for a holistic and strategic view of the industry, including associated development of the supply chain and the transmission grid, is also highlighted. (C) 2010 Elsevier Ltd.

Turbulence and turbulent mixing in natural fluids

Turbulence and turbulent mixing in natural fluids begins with big bang turbulence powered by spinning combustible combinations of Planck particles and Planck antiparticles. Particle prograde accretions on a spinning pair releases 42% of the particle rest mass energy to produce more fuel for turbulent combustion. Negative viscous stresses and negative turbulence stresses work against gravity, extracting mass-energy and space-time from the vacuum. Turbulence mixes cooling temperatures until strong-force viscous stresses freeze out turbulent mixing patterns as the first fossil turbulence. Cosmic microwave background temperature anisotropies show big bang turbulence fossils along with fossils of weak plasma turbulence triggered as plasma photon-viscous forces permit gravitational fragmentation on supercluster to galaxy mass scales. Turbulent morphologies and viscous-turbulent lengths appear as linear gas-proto-galaxy-clusters in the Hubble ultra-deep-field at z~7. Proto-galaxies fragment into Jeans-mass-clumps of primordial-gas-planets at decoupling: the dark matter of galaxies. Shortly after the plasma to gas transition, planet-mergers produce stars that explode on overfeeding to fertilize and distribute the first life.Comment: 23 pages 12 figures, Turbulent Mixing and Beyond 2009 International Center for Theoretical Physics conference, Trieste, Italy.

Experiments Concerning Nonequilibrium Conductivity in a Seeded Plasma

Measurements of conductivity have been made in a plasma composed of argon seeded with potassium vapor. The gas temperature was 2000°K; the pressure, 1 atm; and the potassium concentration was between 0.22 and 0.80 mole-percent. Conductivity values, calculated from a two-temperature model in which the energy dependence of the cross sections and radiation losses from the plasma are taken into account, agree well with experimental values. Measured values of the plasma temperature appear to be about 10% less than predicted values. Relaxation times for the conductivity in response to a step function change in the electric field were proportional to (n_e0l/σ_0E^2) and were a few tens of microseconds for a field strength in the range 3 to 10 v/cm. The ionization rate appeared to be limited primarily by the heating rate for the plasma, and the short relaxation times suggest that ionization occurs by a multistep process. Analysis of conductivity and light intensity data obtained during the transient period indicates that the electron temperature approaches its final value during the first few microseconds
