Air pollution is now the world’s largest single environmental health risk.
The World Health Organisation (WHO) state that in 2012, around 7 million people died because of air pollution exposure. This accounted for one in eight of total global deaths. They estimate polluted air costs the world $3-5 trillion per year and affects 92% of people on the planet. Reducing air pollution could save trillions of dollars and millions of lives. In the UK alone, the economic cost of air pollution is an estimated £54 billion. Every year, over 40,000 deaths can be linked to poor air quality. This is without including new evidence that links with health issues such as diabetes and Alzheimer’s disease.
With a bold new twin-chassis design, our ground-breaking GRAID robot is on track to transform the way National Grid inspects previously unreachable sections of its network. Project Lead David Hardman shares the latest as this innovative pipe dream gets closer to reality.
Human fascination with the power of machines has remained undimmed for decades. So it’s no surprise that our latest robotic innovation – Project GRAID – has been capturing the imagination of everyone from the national press to the gas industry, our customers and stakeholders.
Engineering is responsible for the pulleys, wheels and bows and arrows that carried us towards civilisation. It powered the SS Great Britain across the Atlantic and raised the Eiffel Tower. Without engineering, we wouldn’t have powerful computers tucked away in pockets or a direct line to outer space. Since its inception thousands of years ago, engineering has undoubtedly shaped our world. The question we’re addressing this month, however, is what happens next?
Upon first impression, mine may appear to be a story of failure. At the age of 17, the idea of deciding what to do with the rest of my life was quite daunting. I didn’t know where to start. I chose the option that required the least amount of effort; do what my parents did and become a medical doctor. After applying and being rejected from medicine for two years in a row, I thought I’d better try something else!
Meanwhile, a blue and orange ‘whynotchemeng’ leaflet had found its way into my hands. I remember being impressed by the wide variety of areas chemical engineers can work in. And of course, drawn to the ‘high graduate starting salaries’… I felt like I would have a choice at the end of this degree. As I didn’t have a strong answer for ‘why not chem eng?’, I decided to try it out and see where it took me!
Engineers at the University of California San Diego (UC San Diego) have developed a stretchy fuel cell that is powered by sweat. The ‘epidermal biofuel cells’ stick to the wearer’s skin and can power devices like LEDs and Bluetooth radios.
Fuel cells work by turning the chemical energy in hydrogen-based fuels into electrical energy when the fuel is exposed to oxygen. The chemical reaction takes place at the fuel cell’s electrodes and produce electrically charged particles. These are carried from one electrode to the other, completing the circuit and producing a current.
Combining chemistry, advanced materials and electronic interfaces, the team have made an exciting breakthrough. Their new cells can generate 10 times the power per surface area than any existing wearable biofuel cells.
Around 25,000 aircraft take to the skies every year. Together, they burn 1.5 billion barrels of jet fuel and pump out more than 780 million tonnes of CO2. While this accounts for only a fraction of the world’s CO2 emissions, there is a growing need for aviators to clean up their act.
One popular way to cut the CO2 from flights is to switch to alternative fuels. Sustainable biofuels are a promising candidate to shrink the industry’s huge carbon footprint.
Dating back to the 1600s, chemical engineers have changed the world. The industry’s roots lie in the ancient practice of alchemy, before a shift towards modern-age chemistry. While they never quite turned lead into gold, early alchemists did lead the way in manufacturing handy chemicals like sulphuric and hydrochloric acid.
Two hundred years later, George E Davis made a name for the industry with a revolutionary book. In “A Handbook of Chemical Engineering”, he noted the defining characteristics of ‘the chemical engineer’, and made the case for their distinction from chemists.
The Thames Deckway is an exciting green transport infrastructure project in London. We aim to tackle some of the big urban challenges facing our city and others like it.
With the support of Innovate UK, we are currently working towards realising our technology demonstrator in east London in 2018.
New figures from Transport for London (TfL) show that more people are cycling in the city than ever before. Despite this, currently one bicycle journey in every 515,000 ends in death or serious injury. At the same time, air pollution from vehicle emissions results in a wide range of health impacts, which significantly reduces life expectancy within the city. Compounding on these issues, projections of future climate change paint a bleak picture. For example, with much of the transport network below ground, more than 57 tube stations would be at risk of climate induced flooding.
