Solar energy for heating water has been around for centuries, but solar 'cooling'? There is something counter-intuitive to it a sort of energy alchemy seemingly at odds with physics, but solar thermal cooling is indeed the hottest new twist in the rapidly expanding field of solar energy applications. Worldwide there have been several attempts at solar chillers dating back to the mid-1800s, but these were not developed further because oil and coal energy was so cheap. Solar thermal arrays look like photovoltaic panels, but are essentially comprised of water-and-glycol-filled tubes that absorb heat energy from the sun. The heated fluid is circulated to a storage tank, where the heat is transferred via a heat exchanger to warm water for domestic use solar thermal for hot water production. - Author(s): L. Douglas

The author looks at engineering solutions to the age-old problem of cooling the London Underground. London Underground introduced a programme 'Cooling the Tube', which is ongoing. David Waboso, director of London Underground Upgrade, points out that there are two types of lines on the Underground's subsurface averaging about 5m (16ft 5in) below the surface and deep level, about 20m (65ft 7in) they both require different approaches. He believes the subsurface lines can be controlled through air-conditioned trains being deployed. - Author(s): D. Gross

The EU has mandated that the UK energy suppliers rollout smart meters. A smart meter is an advanced meter (typically an electrical meter) that identifies consumption in more detail than a conventional meter and communicates that information over a wide area network back to the utility company. In this paper, the author investigated the security issues in the deployment of smart meter. - Author(s): N. Smith

The efficiency of a machine, whether it is a steam engine or an information processor, rests on the second law of thermodynamics, which is all about entropy: that is, the energy 'lost', usually in the form of heat, whenever one kind of energy is transformed into another. In their analysis, Parker and Walker revisited the heat engine concept which provided the foundation for the second law of thermodynamics and applied this to a computer. Based on their Carnot analysis, they developed a formula using processor temperature, bit rate and power consumptions as variables that can be used for comparing the absolute energy efficiency of any information processor on a logarithmic scale. - Author(s): G.

Most of these planets have been found using a method called radial velocity, also known as Doppler spectroscopy. This method is independent of distance and is good at finding massive planets close to stars that are relatively nearby, about 160 light-years from Earth. However, it can't determine the planet's physical aspects such as its actual size, orbit and whether it has an atmosphere, so it is often used in combination with what's called the transit method. Combining this with radial velocity enables astronomers to determine the density of an exoplanet, and hence learn something about its physical structure.The European Southern Observatory (ESO) uses this combination of techniques at its various telescopes around the Atacama Desert in Chile. Its latest addition called Trappist (TRAnsiting Planets and Planeteslmals Small Telescope) relies on the transit method but whereas the ESO's other telescopes are manned, Trappist is a robotic instrument, controlled remotely. It's also designed to study comets orbiting around the Sun but, whichever the task, it receives its instructions from the University of Liege inBelgium, nearly 7,500 miles (12,000km) away. - Author(s): T.

Huge platforms in the Arctic waters off Russia's east coast are defying the elements to produce vast amounts of valuable oil and gas. The exploration and production offshore of Sakhalin is managed by Sakhalin Energy, a consortium of Gazprom, Shell, Mitsui and Mitsubishi. The company was set up 15 years ago to manage the field. The first resources came from Sakhalin I, which started producing in 1999. The oil and gas was stored at the drilling platform and collected by tankers. However, because of the frozen conditions it was only able to operate for six months each year, and therefore the decision was made to construct an 800km pipeline to the nearest year-round accessible port at Aniva Ray, on the south side of the island. - Author(s): S.

Properly protecting intellectual property (IP) in the form of software is complex, and the question of whether a piece of software can be truly patented has a colourful and controversial history. Many enterprises that develop their own software do not realise that they possess assets that can create revenue. Open source software is software available in source code for which the source code and certain other rights normally reserved for copyright holders are provided under a software license that permits users to study, change and improve it. - Author(s): M.

There's little more summery than a cool pint of ale or a cold lager. New technology in brewing ensures that it doesn't come at the expense of the environment, says Bryan Betts. Like most industries, brewing has come under pressure to improve its sustainability and, in particular, its use of water; energy and transportation. Brewers of all sizes have responded by turning to technologies both old and new, as they re-engineer their processes to save cost and cut wastage. - Author(s): P. Dempsey

When Ross Stuart finished writing his book on turnaround skills for business managers, he decided that the best way to reach his readership was through the emerging e-reader technology platform. Ross Stuart, a professional manager in the manufacturing sector for more than two decades, was convinced that there was a more direct approach, and with the arrival of the e-reader technology platform he saw his break. His new book 'Business Transformation' has been published as a downloadable pdf that you can upload for free onto your iPad. - Author(s): N. Smith

Summary form only given. The paper states that as engineering managers we're all caught on the horns of the same dilemma. We want to climb the slippery corporate pole, but in doing so we get further and further away from why we became engineers in the first place. It's called 'ghost' work, and we all do it. It's that niggling, depressing stuff that we have to get off our desks in order to be perceived to be doing our jobs properly. As engineering managers we spend most of our time writing reports, administrating employment issues, dealing with compliance legislation and writing even more reports. At best it's tedious pen-pushing. At worst it's simply not what we were put on the planet to do. The reason we feel like this is that we are supposed to make things, design things, repair things. That's why we did our vocational degrees in the various engineering disciplines. But today, as we sit in our rabbit hutches signing requisitions for photocopier toner and haggling over how much holiday can be passed on into the New Year, we've never been so far away from getting our hands dirty. The dilemma can be summed up as 'manual versus mental'. - Author(s): D. Birkett
