Smarter, bigger, faster, safer: how welding technology is meeting the challenges of the twenty-first century
Posted by James Chater | 01 May 2018
Welding has the image of being a down-to-earth, hands-on activity, but a lot rides on it in terms of safety, both to plant and to personnel. A skills shortage makes the task of training enough welders more urgent. This is where technology comes in: the welding tools being developed today are smarter, (sometimes) bigger, faster and safer than before. More ergonomic tools and robotics will go a long way towards filling the skills gap.

Lift-off: energy storage brings renewable energy to the mainstream
Posted by James Chater | 16 January 2018
In the past, a severe shortcoming of renewables has been that they are intermittent: the power stays on only as long as the wind blows or the sun shines; if the wind blows too hard, the turbines must stop turning in order not to overload the grid. Newer and more efficient storage techniques are changing the equation. It is now possible to store excess power and tap into it during periods of power shortage. This article outlines some of the many technologies employed.
