As a company spanning engineering and the arts, both the very nature of energy and its functional application have always been central to what we do. From dramatic show moments that trigger a simultaneous upsurge of emotion amongst thousands of people, to 60-foot flames erupting with a thunderous shockwave – the harnessing and visualization of energy in its most visceral forms are the essence of the experiences we create.

Feeding the world with AI

When we hear about food waste, we tend to think of wastage at the consumer side of things – the bag of half-eaten salad mix you guiltily throw out every week, the enormous meal at a restaurant you couldn’t finish, or your parents sternly reminding you of the ‘starving children around the world’ as you pick at your peas.

Food loss and wastage, however, is a pervasive issue at all stages along the food supply chain from production and storage through to transport and consumption.

The Food and Agriculture Organization of the United Nations (FAO) claims that one-third of food produced for human consumption is lost or wasted globally – equal to around 1.3 billion tonnes annually.

While consumer-side efforts have been launched in recent years to combat this issue (such as ‘ugly’ fruit and vegetable campaigns, and apps that let consumers buy cheap food from cafes before it gets binned), there’s an opportunity to combat the issue on the production-side by harnessing AI and machine learning (ML) technology.

Our oceans are dirty. AI-powered robot microscopes may save them.

In five years, small autonomous AI microscopes, networked in the cloud and deployed around the world, will continually monitor the condition of the natural resource most critical to our survival: water.

From farms to fridges – engineering and the food supply chain

For engineers, a large part of achieving this goal involves guaranteeing that the technologies and practices developed are sustainable. If not sustainable, then the developments merely provide a temporary patch for the problem, rather than an actual solution. Thankfully, as QEPrize donor company Hitachi writes, ag-tech solutions that optimise food production, improve food distribution, and reduce food consumption are already being implemented.

Urban Crop Solutions – sustainability and vertical farms

Before you dive into this article too deeply, take a moment to read the following description, and then close your eyes for a second. Imagine yourself standing inside a climate-controlled, high-ceiling warehouse. In front of you stands a tower with eight irrigated levels, on each of which lettuces, herbs, microgreens, and baby greens grow under LED lights. Robotics bring trays with young plants from outside into the right position in the growing tower, while on the other end fully grown crops are taken out, ready to be harvested. Can you see it? You are standing in Urban Crop Solutions’ PlantFactory – an indoor vertical farm – a highly engineered manufacturing plant producing not goods, but crops.

The state of engineering – food and water security

Achieving food and water security is a key priority for people, organisations, and government bodies around the world. However, due to a combination of factors – for example, population growth, climate change, lack of infrastructure, the high cost of maintaining existing infrastructure, or prioritisation from particular governments – achieving food and water security globally is proving to be not only an uncertainty but an increasingly complex problem.

While challenges in food and water security are often associated with developing countries – where poor infrastructure or inhospitable climate conditions limit either access to safe drinking water or agricultural productivity – a lack of resource security is a threat for the developed world as well. Engineers around the world are diligently working to produce innovative, relatively low-cost technologies that improve grey and green infrastructure, create new and efficient processes, and optimise social behaviours. If through these innovations, we can increase supply, reduce the demand on existing systems, and allocate resources differently, then we are a step closer to achieving global food and water security.

Arcadia’s fire-breathing spider inspires young engineers

Imagine that you’re in the middle of a festival crowd, dancing away to the most dynamic names in music. 50-foot fireballs are exploding into the air, audience members are being abducted by acrobatic performers and luminescent creatures are swooping from the sky. Oh, and imagine that you’re looking up at a 50-tonne mechanical spider.

Arcadia is a performance art collective renowned for engineering mechanical monsters that they use as large-scale performance spaces. Perhaps the most recognisable of these is The Spider, a 360-degree structure built from recycled materials. Created by sculptors, engineers, painters and pyrotechnicians, the arachnid is an experiential dance stage for festival attendees.

Optimising materials to create world class wind turbines

  • Posted by QEPrize Admin
  • 12 January 2018

At over 80 metres in length, a single blade from a wind turbine is an impressive feat of engineering. Modern offshore wind turbine blades are now the largest fibreglass components ever cast in a single piece. This has been made possible through continuous improvement in materials development. The layering and structuring of fibreglass was originally a craft used for building the hulls of boats. Now, the design of composite materials – a group of materials which includes fibreglass – is done by international teams of engineers working together to create these record-breaking components.

Materials engineering is uniquely important to the design of wind turbines, particularly because there is so much of it! As the industry has grown, so has the size of our machines, with the largest now gathering wind from an area greater than three football pitches put together. The area that the blades sweep through is an important factor in turbine performance. At a given wind speed, the amount of power which can be extracted from the wind increases by the square of the blade length – 3 times longer blades, 9 times more available power. However, if things are simply scaled up, the mass or weight of the blade increases by the cube of the length – 3 times the length, 27 times the mass!
