Novel torque sensors aid tidal turbine development
Novel non-contact torque sensors are playing an interesting part in the development of commercial-scale in tidal turbines, being built by Irish marine technology firm, OpenHydro.
Efficient energy
Combined heat and power plants are anything but new. However, evolving technologies are revolutionising their scope and HM government likes the sound of it. Brian Tinham reports
Cut the energy hype
Although oil prices have come down, the recession is forcing organisations of all kinds to keep on cutting energy costs. One consequence is increasing numbers of companies seeing energy saving as a business opportunity - and hence the growing number of ferings available. But while most ideas are good and very workable, others, inevitably, are either naïve or downright fraudulent.
The key to 'greener' energy - advanced plant
It is increasingly obvious that only a combination of engineering technologies is likely to be able to meet the world's growing energy needs in the near term without totally destroying its climate and environment.
Turning the tide
While wind farms, for most of us, are the iconic, if not entirely friendly, face of renewable energy, there's a quiet revolution readying itself for launch on an unsuspecting public. The new talking point will be marine turbines. Not only could they challenge wind, but also nuclear plants - and soon. As we go to press, a full-scale commercial marine turbine, designed to harness tidal energy, has been installed and commissioned on the Irish coast, and is undergoing final tests before running up initially to 1.2MW electricity generation.
