The Energy Saver: Jean Malone, Siemens Ireland


Jean Malone, pictured above, has found career success at Siemens Ireland as Manager of its Dublin-based Energy Centre

As fuel costs rise, industry must find ways to reduce its energy costs in the short-term and introduce efficiencies that protect it against future price hikes. The Energy Centre at Siemens Ireland is helping customers all over the world – from Cork to China – to do that, and heading up this operation is TCD engineering graduate Jean Malone (2006).

The Centre in Ireland is set to be at the heart of Siemens’ strategy to be a strong local partner to its customers by providing energy savings for them despite the relentless rise in fuel costs as the demand for fuel increases, and the taxes on their use – greenhouse gas taxes – likewise increase. At the heart of this is Jean Malone and she is proud of what’s been achieved so far for Ireland.

‘We are gearing up at the moment.” said an excited Jean. “Our system can handle a couple of hundred customers right now, but we are planning to add around 1,000 new customers per year.” Siemens Ireland is engaging with local branches of Siemens in Turkey, the Czech Republic, Italy, Holland, Portugal as well as Germany, and as far away as Chengdu in China, to help a new manufacturing plant.

Human’ engineering

Jean, who is from Clane in Co Kildare, recalls loving maths, technical graphics and all the technical subjects when she was in secondary school. She was specifically drawn to the medical device sector, as it combined engineering with some direct human benefits. However, after her Leaving Certificate in 2001, she decided that it would be best to select a general engineering course to begin with, and she chose engineering at TCD.

She enjoyed college life at TCD, but after Jean completed her second year, she began to have some doubts as to whether engineering had been a good idea. “The course was tough, but rewarding – but I couldn’t foresee what my future job or career would be like,” recalled Jean. “I wasn’t sure if it was right for me – and I took a year out between 3rd and 4th year.” She needed some time and space to go travel, and figure out exactly what she wanted to do. Her parents were okay, she said, but wanted her to do work experience, for at least part of the time she was out of college. She agreed to do that.

Jean applied, and was accepted to do six weeks of work experience at a company called Chiroxia, based at Citywest, which had been set up by Jim Coleman, a vascular surgeon, who had returned from the US full of ideas for various kinds of medical devices. The company employed engineers to realize Coleman’s vision. It was an exciting place to work, and Jean immediately felt at home there, and enjoyed her work immensely.

Her profile at the company increased when she observed a particular behavior of a substance – at high and low temperatures – that was being prepared for insertion into the human body, which hadn’t been observed by any of the full time engineers at Chiroxia. This was a technical breakthrough for the company, which led to some design changes.

Jean was offered a nine-month contract, which she accepted. In that time she applied knowledge that she had learned in her first three years of college. This work experience changed everything, and any doubts she had about a career in engineering disappeared. “I went back to do my final year full of energy. I was so excited about the topic when I got back, and it completely changed how I viewed the course as well,” said Jean.

Crash response

When the Irish property market crashed ‘almost overnight’ the Irish arm of Siemens AG – the massive engineering and electronics corporation, headquartered in Munich, and employing 370,000 people in some 190 countries – started to look at how existing, or old buildings could be improved or upgraded, as the ‘new build’ market had evaporated.

Siemens put a toe in this market when they developed an energy efficiency plan for a large Ireland-based customer. The idea was to conduct a complete ‘audit’ of the energy usage at the customer’s manufacturing plant. This was done by strategically placing energy meters at key locations in the production plant, and gathering a data stream. That data was then  looked at by a team of energy engineers at Siemens Ireland, who made recommendations to the customer on how to improve energy efficiency.

Siemens Ireland decided to set up an Energy Centre locally, so that this large customer could go online at any stage and look at how it was consuming energy. Once the Centre was up and running, it made sense to offer similar services to other companies base in Ireland.  Eventually, what had started as a local R&D project attracted the interest of Siemens HQ in Germany, who have supported the development of the Centre to provide energy efficiency services for its customers across Europe and beyond.

Success at Siemens

Jean completed her degree at TCD in 2006. After that she worked briefly as a waitress in Belfast before returning home to Co Kildare, where she lived again with her parents for a short time and got a temporary position with Green Isle Foods in Naas. She was glad to be back home, but was keen for a job that would allow her to live more independently.

She started to look for work in Dublin, and an opportunity came up with Siemens. Initially, her job involved working with customers to identify the exact product that they required; to help them find the right product, and the correct complementary products. The idea was to refer customers to websites and give them the skills and knowledge to be able to source new parts themselves.  She did that successfully and then moved on.

The next role was more interesting, as it involved working with a customer to develop an energy efficiency solution. First, Jean worked with a sales person to design a solution suited to the customer’s energy needs, then she worked with a project manager who would roll out the solution for them. It was a challenging, diverse and interesting job.

It also helped Jean’s career and she was offered the role of Siemens Energy Centre Manager. In this role she deals with some very large customers in Ireland, in energy intensive sectors such as pharma, chemicals, food and leisure. The Irish Centre is also responsible for meeting the energy needs of Siemens’ customers based in Britain and Northern Ireland, as well as a growing number of customers across Europe and beyond.

“I enjoy the diversity of the role, each site different challenges, and you have to adapt to those challenges,” said Jean. “Within Siemens there are so many different opportunities. I do enjoy the idea of working towards something that will create more jobs for engineers in Ireland. We have a plan to expand and we have just taken on 4 new people recently under the Job Bridge scheme,” she added.

THE CAR STARTER: Nicholas Callan & the ‘Model T’ Ford


1926 was the first year that cars such as the Ford Model T roadster, pictured here, came with automatic starting batteries. Cars now started up at the turn of a switch thanks to technology developed by Irishman Nicholas Callan (Credit: automotivehistoryonline.com)

Up to 1926, all cars had to be ‘cranked up’ by hand, in order to get started. From that year onwards, Model-T Ford cars came with starting batteries, which meant that a car could be started without physical labour for the first time.

The technology that made this possible was the induction coil, which had been invented in the middle of the 19th century by Nicholas Callan, a priest and scientist, born in Co Louth that was based at St Patrick’s College, Maynooth.

Callan’s coil made it possible to massively ‘ramp up’ the power that could be supplied from a small battery. This was done by rapid interuptions of electrical current, which meant up to 600,000 volts could be produced from a 12 Volt battery.

This induction coil, or electrical ‘transformer’ technology, meant that sparks could be created that ignited the petrol in the car, sparked the pistons, and, this in turn, drove the crank shaft and powered the engine into life.

It was a technological breakthrough that made it far easier to operate cars, and made them more appealing to a mass market. Callan, however, did not get credit for his invention until at least the 1930s, some 70 years after his death.

The Secret to Insect Success: The Cuticle

Insects have been around for hundreds of millions of years, and are found in large numbers even in the harshest climates around the world.

So, what is the secret to their success? Well, one major factor is undoubtedly the cuticle, which covers the outer body of insects, such as the grasshopper pictured here on the right.

Despite the abundance of cuticle – it is the second most common natural material on the planet – no-one had studied its engineering properties in detail.

Until now that is.

Dr Jan-Henning Dirks and Professor David Taylor at the TCD Department of Mechanical and Manufacturing Engineering have shown that cuticle is flexible, lightweight, very strong, and crack resistant.

These are properties of interest to many industries, such as airplane manufacturers, for example.

Solar Cell material breakthrough at TCD

Solar energy has huge potential, in Ireland and around the world. For example, scientists have calculated that the entire energy needs of the USA could be provided by solar cells covering two per cent of that nation’s landmass.

Two per cent sounds an awful lot to cover, in a country the size of the US, but this figure corresponds to the area taken up by the country’s motorway and highway network, and the area covered by all of the nation’s rooftops.

It might be a difficult proposition, therefore, but with the will and investment it could be done, in the US or elsewhere.

The thing that is holding such an ambitious project back right now is the fact that the primary material used to make solar cells these days is silicon. Silicon, derived from sand, is expensive, so another economically viable material needs to be found.

The good news is Professor Igor Shvets and his team at TCD and CRANN have developed a cheaper and better option to silicon solar cells. It’s chromium dioxide – with the addition of some nitrogen and magnesium atoms – and it is proving a very promising material indeed.

Researchers believe it could pave the way to huge deployment of solar cells, and also lead to improved flat screen TVs, and other electronic devices.

THE INVENTOR OF THE STEAM TURBINE: Charles Parsons


Charles Parson’s yacht Turbinia, pictured here, was powered by his steam turbine. He dramatically demonstrated its speed at the British Navy Review before Queen Victoria in 1897 when it was easily the fastest vessel on view. The British naval establishment was impressed and soon adopted the turbine in its latest battleships (credit: Wiki)

A plentiful supply of cheap electricity, and much faster passenger steamships and military battleships. These were some of the things made possible by Charles Parsons, who grew up in Birr, and invented the steam turbine in 1887.

Charles was born in 1854 and came from a brilliant scientific lineage. His father was the famous astronomer, William Parsons, who had built the world’s largest telescope on the grounds of Birr Castle in the 1840s.

The steam turbine invented by Charles, hugely increased the power that could be harnessed from a steam engine. The invention made him a rich man, and it changed the world.

Microelectronics in Ireland – The future is bright


Credit: Microelectronics Competence Centre Ireland

The Irish economy might be on its knees, but here and there, there are some signs of hope. One of our brightest hopes is for the continued success of the microelectronics industry here.

Microelectronics is all about the tiny components we put into our beloved modern devices to make them work better, such as microchips for our laptops, SIM cards for our mobile phones, and ID chips on our laser cards.

Ireland is very good at doing this, and the industry here is made up of a mixture of global giants such as Intel, which, of course, make computer chips, to vibrant indigenous companies.

And, crucially, the sector is still creating jobs, hundreds of them, and will continue to do so over the next few years.
