Why electrical engineering is fundamental in green buildings

Buildings have become more energy efficient thanks to construction practices that emerged in the last few decades, writes Jahnavi Sajip @NewYorkEngineers. Older buildings were designed assuming open windows, and heating systems were oversized as a result; on the other hand, modern construction practices focus on insulation and air-tightness to reduce heating and cooling loads. However, there is still a key challenge to overcome: space heating and hot water systems are very dependent on ...

Breakthrough in construction of computers for mimicking human brain

A computer built to mimic the brain's neural networks produces similar results to that of the best brain-simulation supercomputer software currently used for neural-signalling research, finds a new study published in the open-access journal 'Frontiers in Neuroscience'. Potential to overcome speed and power consumption problems of conventional supercomputers Tested for accuracy, speed and energy efficiency, this custom-built computer named SpiNNaker, has the potential to overcome the ...

In the eye of the storm: ESB Networks ops manager's Ophelia story

Before the storm ESB Network’s preparation for Storm Ophelia started on the Thursday morning beforehand [Ophelia hit on Monday morning], according to Derek Hynes, ESB Networks operations manager: “We get a five-day look-ahead weather forecast every morning. We had heard rumours of severe weather before that, but five days is at the outer envelope of what Met Éireann can provide with a high degree of accuracy.” ESB Network’s operations manager makes the call in terms of escalation. ...

Three tips for testing cabling

While we may like to think of the modern world as being wireless, cabling remains an important element in almost all electrical systems. It is therefore essential that engineers know how to test cables effectively to ensure they are fit for purpose. Here, Matt Collins, business development manager at Ide Systems, explains what engineers should look for when testing electrical cabling. It was in the early days of the 20th century when renowned inventor and electrical engineer Nikola Tesla ...

Energy expert Prof Radgen on the do’s & don’ts to help industry identify missed efficiency opportunities

At a recent seminar held in Cork, Professor Peter Radgen outlined the key requirements to improve compressed air systems and shared his insights based on years of research and hands-on experience in helping German industry to achieve increased energy efficiencies. Chair of energy efficiency at University of Stuttgart and director of the Graduate and Research School Energy Efficiency Stuttgart (GREES), Prof Radgen was the guest speaker at the seminar organised by compressed air specialists ...

Researchers build a water-based battery to store solar and wind energy

Stanford researchers have developed a water-based battery that could provide a cheap way to store wind or solar energy generated when the sun is shining and wind is blowing so it can be fed back into the electric grid and be redistributed when demand is high. The prototype manganese-hydrogen battery, reported recently in 'Nature Energy', stands just three inches tall and generates a mere 20 milliwatt hours of electricity, which is on par with the energy levels of LED flashlights that hang ...
