An Unusual FTSE Boss

adam-and-paul-iv

Interviewing Paul Polman, CEO of Unilever

(I think my questions are sticking out of my back pocket)

Paul Polman is an unusual man for at least two big reasons. Most obviously, he is unusual because he is Chief Executive of one of the world’s biggest consumer brand companies, Unilever. But in many decades of interviewing senior executives he also strikes me as very unusual because of his willingness to engage in subjects of global concern such as environmental threats.

Much of the time of a CEO is spent trying to keep the support of major shareholders. Polman has been CEO for longer than most and it’s interesting therefore to know that in his early days running the company, rather than trying to keep shareholders on board, he spent much time trying to get rid of them. Many shareholders want short term returns, he told me. What he wanted was owners who were willing to look to the long term and so he tried to change the ownership of the company to those who would support those long term aims.

Polman appears to be a boss genuinely concerned about the environment and believes that companies can play a constructive role in helping improve it.  To that end he is tackling the problem of waste head on. Unilever says all of its factories now have zero waste – 600 factories globally recycling materials to create no waste at all, they say.

That’s quite a claim and something many believe is a model which others could follow,

The world produces nearly four million tonnes of municipal waste every day. If this trend continues, the daily amount is set to more than double by 2050.

Looking over the river Thames on the roof of Unilever’s headquarters, Polman explained his corporate philosophy to me:

“Our role here is to look after the globe for future generations. Whilst we’ve been incredibly successful lifting enormous amounts of people out of poverty, unfortunately we’ve done it in a way that has resulted in quite a lot of over-consumption, acidification of oceans, plastic in oceans, air pollution, water pollution and frankly, leaving too many people behind.”

I asked him whether he felt it was too much to describe the environmental challenges we face as a crisis?

“No it’s not too much. Only 5% of packaging gets reused. So what we’ve now discovered because of population growth, this enormous level of consumption that has happened is that we need to move to a more circular model, where someone’s waste is someone else’s input.”

So just how is Unilever creating zero waste factories? One of its success stories involves a popular British food – Marmite. This savoury yeast spread is itself a by-product of the brewing industry – And now workers in Burton on Trent have come up with a use for the by-product of the marmite-making process.   They’re turning the sludge left in machines – which would previously have been washed away or been sent into landfill – into biogas.

That’s just one example of a different approach to manufacturing. I put it to Polman that this was rare. Indeed, perhaps it was an approach that other bosses shouldn’t take. After all their job is to make money for their shareholders who are trying to get a return for pensioners and their investors who need the company to make money rather than make an environmental statement.

He disagrees. He tells me that companies are corporate citizens who have a responsibility to lead change. But in leading change they don’t have to stop making money, indeed it’s just a new even more efficient way of creating sustainable profit.

He tells me “You have to believe in the goodness of people, which I sincerely do. You need to educate CEOs themselves to be able to verbalise to the financial community why it is important to invest for the longer term.”

One of the big challenges facing the world is sanitation, or the lack of sanitation. I asked Polman what companies like his do to help that?

“Yeah, it’s a tremendous opportunity actually” he says. “Despite the tragedy that 2.3 billion people don’t have access to clean drinking water or sanitation. We have set a goal to actually reach 1 billion people in the world with handwashing. The simple act of handwashing can cut infectious diseases like pneumonia, diarrhoea, by 75%. Currently we see every year 650,000 children die unnecessarily of these infectious diseases.

There’s over a billion people that don’t have access to sanitation in the sense of open defecation. Since our bleach cleaner Domestos is single-mindedly focused on building toilets, the brand is growing double digit.”

I asked him whether he felt such acts were part of the company’s charitable works – and he interrupts me before I’ve even finished the question.

“No, it’s not a charitable act for us. It’s an integral part. The more people have toilets, the better it is for Domestos. The more people wash hands, the better you sell your bar soaps.”

There are many in the world who try to make it better. There are many in the world who try to build companies, offer employment and improve economies. Paul Polman is a man who believes you can do both. Almost his final words, before we shook hands and left were these:

“We find out that every brand that has a strong social mission, because ultimately brands should be there to address issues in society, otherwise why should we accept them to be there? But the brands that have the stronger social mission grow at twice the rate of brands that don’t, and are actually more profitable as well. It makes good business sense.”

A Slice of The Sun

Energy – limitless, abundant and clean. That is the goal of scientists trying to create new energy sources.

Nuclear power has for a long time been the centre of much controversy. Although it doesn’t create the pollution associated with fossil fuels, it does leave us with an almost unimaginable period of radioactive waste, Radioactive isotopes eventually decay, or disintegrate, to harmless materials. Some isotopes decay in hours or even minutes, but others decay very slowly. Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years). Plutonium-239 has a half-life of 24,000 years.[1]

So whilst nuclear power might provide a short term fix to pollution problems it can also create other problems which might last longer than modern man has existed. That’s why so many people are so worried about it.

But a tantalising possibility has been raised by nuclear scientists to create a form of nuclear power that provides almost limitless power with few side effects. This nuclear power is based on fusion. Traditional nuclear power stations are based on fission. The difference may sound little more than the replacement of a few vowels – but that is very misleading.

Fusion nuclear power is a world away from the fission power we know today and it involves creating a bit of the sun right here on earth.

The race is now on to design a fusion reactor. In France, they’re building one of the largest machines the world has ever seen. .

Burn one kilo of fusion fuel, it will generate the same amount of energy as ten million kilos of fossil fuel.

The problem is that nuclear fusion has for years been held up as a possible solution to our energy problem. It has always been the next big thing, but it’s never been the thing. However, there now does appear to be a critical mass of scientists, a new generation of brains determined to crack the problem.

So here is how it works. At the moment all of our nuclear reactors rely on nuclear fission. This process relies on the ability to split atoms to produce lots of power, but also, lots of radioactive waste.

A fusion reactor will join atoms together. It’s likely to be Hydrogen to form helium, like our sun. Any radioactive waste, they say will be relatively short-lived.

And the fuel? Well hydrogen is found readily in water, abundant the world over.

The proponents of fusion power have for years been promising us a plentiful and relatively safe form of new energy – well here at ITER in France they are starting to make good on that promise.

Over 200 experimental reactors have been built worldwide. But to date they’ve all consumed more energy than they produce. In other words they can make fusion happen but it takes so much energy to make it happen, that its pointless. You put in more energy than you get out.

The International Thermonuclear Experimental Reactor, or ITER, hopes to turn this situation around.

It is an enormous project. It’s going to cost at least 15 billion euros. It involves 35 nations and when it’s done they say it will be the largest experiment ever conducted by man.

It will be a 23-thousand tonne nuclear laboratory. Three times heavier than the Eiffel Tower.

The man heading up this remarkable scientific test bed is Bernard Bigot, ITER’s director general.

I asked him on the grand scheme of human innovation and science, how significant he thought this project was? His answer was unequivocal. “It is one of the most striking change in the history of technologies.”

That’s quite a claim. He and the other supporters of this project believe it could transform the world’s relationship with energy. He believes it will happen within the next 40 – 60 years. It’s not quick but science that might change the world never is.

The journey to a new energy source – is our Horizons programme this week. Do watch it and tell me what you think on Twitter at @adamshawbiz

A Hug and A Shot

We experience the world through our senses. Sight, sound, touch, taste and smell.  A problem with any one of them and you need help – a pair of glasses for instance. Or even a hearing aid. Well, we’re about to enter a new world of sense technology aided by Virtual Reality.IMG_0950.jpg

The sense of touch doesn’t really get the attention that the other senses get like sight and sound and yet it’s incredibly sophisticated. It enables us to tell between wet and dry, hard and soft, it gives us pleasure and pain – so could we create a second skin which creates sensations through electrical impulses? Well I’m about to find out.

I’ve arranged to meet the people behind a Tesla Suit. It looks like a wet suit but enables users to interact with the virtual environment and actually “feel” what’s going on inside a computer. It’s been designed by a group from Belarus who are now based in the UK.

The Tesla Suit uses something called haptic feedback – which is the mechanical stimulation to recreate the sense of touch and mimic sensations we experience in the real world so that we can feel them in the virtual world. At present the technology is, in the main, being advanced by the gaming industry, but there are potentially other far-reaching applications.

Before we started filming, there was much talk of my chest measurements and arm lengths so the team could ensure the suit fitted. I was under the impression there might be a range of them for me to try. As it turned out – there was only one. It was so tight it took three men to push me into it and do it up. Amazingly, once inside, I was so held together by the rubber – it did make me look rather buff – definitely worth the pain of forcing myself into it.

Dimitree Marozau is one of the founders of the Tesla Studios. He says it’s taken three years to create the suit and he let me put it through its paces.

I put on some virtual reality glasses and started a shooting video game. The different was that when my character in the game was shot, I actually felt a pain in my real body – delivered by the suit I was wearing.

It works – you don’t like being shot in the virtual world – because it delivers real pain in the real world.

But it’s not just for gamers. Dimnitri says it could deliver a virtual hug to you from your family – if you are abroad. He demonstrated by hugging the empty space in front of me – saying I would now feel a real hug through my suit.

In reality I just felt lots of small electric shocks. It wasn’t like any hug I’ve ever had. But the fact that it works at all is a small miracle.

The company says that the technology is just opening up a range of possibilities.  Dimitri says “Our vision was to send it over to space, because muscular atrophy is the biggest problem in space because people are not working out as much or they have to forcefully work out. Electrical signals conveyed by the smart fabric could be used to make the muscles of astronauts contract, compensating for the lack of gravity, and giving them a work out.”

There is research going on at the moment with people who have strokes. The recovery process involves electrical stimulation in certain parts to help the muscles to regain their memory, how they work, and to stimulate different parts of the body. And probably this one could take it to a next level.

This sensory technology may have started in the world of gaming but it’s already slowly moving into the world of medicine. Now that kind of science really does have the possibility to change the world and our experience of it.

The Underground Food Movement

 

I am standing on a busy corner in South London. Cars are hooting at each other, people’s heads are down as they walk quickly to an office or home and barely anyone notices a padlocked gate to an off round building set slightly back from the road.

But it is here that a revolution in farming is starting that could help bring agriculture from the leafy countryside right into the heart of our noisy cities.

There is no obvious bell to ring – so I shout and a friendly face pops out from a Portacabin. The face belongs to Steven Dring, who together with Richard Ballard has built a farm 33 metres below street level in the dark and damp tunnels of an old municipal bomb shelter. Their company is called Growing Underground.

We pull open the metal doors to the stairwell and take the long walk down the spiral staircase. It looks like a disused railway station but Steve tells us it was a shelter for VIPs during the war. The locals got annoyed that they couldn’t use it and persuaded the authorities to open it to everyone. However it took so long to build, no one is sure that it was ever actually used.

At the end of one of the tunnels they have constructed a tent in which they can control the lighting, hearing and circulating water supply. To the background sound of the rumbling tube trains which seem to be all around us, they are growing salads for use by restaurants. One of their backers and customers is Michelle Roux Junior – the Michelin starred chef and owner of the restaurant La Gavroche – which sits the other, distinctly more upmarket, part of town.

We have lots of filming to do, Steve says there is a phone linked by cable to the surface, so we can call him if we need to find our way out. With that, he leaves us to our own devices whilst he heads top-side to sell more salad.

We wondered around with the square LED battery light we use for filming and occasionally turn it on under me face to add to the ghoulish feel of the place. It wasn’t long before we got lost. Every tunnel looked the same. Endless damp tubes seemingly leading to no-where.

Getting lost was funny then it was worrying. I can get lost when I’m in central London and can jump on a bus to get me home – so down here with no obvious way out – it was clear I should never have gone far from the phone connection to the surface.

The crew were more confident of finding our way back and did eventually get us back to the tunnel being used to grow salad. I picked up the phone to say we could do with a guide to find our way back to the exit stairs – only to find that wasn’t working.
Well at least we wouldn’t starve. We had a tunnel full of salad to keep us going until someone noticed we were missing.

This underground farm is a curious world within a world. A world of opposites – dark, damp and un-light brick tunnels hosting a brightly light tent, smelling of fresh herbs and the sound of filtered water being pumped round.

But this underground farm isn’t meant to be just a novelty. Food miles accounts for a huge amount of wasted energy in the food industry. Transporting food from farm to fork involves a lot of transportation, packaging, pollution and waste. Bringing food production nearer to where it is consumed can help dramatically cut the waste and pollution.

The company I’m visiting, claims its food can be picked and in a kitchen within 4 hours of being picked and packed. By using the latest hydroponic systems and LED technology, their crops can be grown year-round in the perfect, pesticide-free environment.

Because it has total control over their environment, they can create a consistency that helps quality control.

Their hydroponics system, they say, uses 70% less water than traditional open-field farming, and because all the nutrients are kept within the closed-loop system they say they run no risk of contributing to agricultural run-off.

Bringing food production closer to the market is serves is an appealing notion. Whether it can be a significant contribution to world agriculture, is another matter. But who knows, maybe one day the cities will be home to hundred of underground farms where city inhabitants need only reach below their feet to pluck a carrot and a nice sprig of rosemary.

The Rise of The Robot Surgeon

The robot Surgeon is a phrase, which conjures up a clinical foreign future. But it’s wrong to think of it like that for a couple of reason.

Firstly it’s not really the future; it’s already with us. Secondly, the surgeon is no more robotic than they are now – but the tools they are using are becoming more advanced and robotic-like.

To understand the future of surgery I went to a low-rise building just off one of the main roads in Sunnyvale California. The town is home to the headquarters of Yahoo and sits in the centre of the high-tech Silicon Valley. That’s no coincidence – this is a technology company as much as it is a medical one.

Globally the market for medical robots and devices is growing. It’s already worth more than five billion dollars – and is set to be worth nearly 14 billion dollars by 2018. [1]

The company I was visiting creates a robotic surgery technology called the Da Vinci system.

Da Vinci robots operate in hospitals worldwide, with an estimated 200,000 surgeries conducted in 2012, most commonly for hysterectomies and prostrate removals.[2]

However the Da Vinci robot is thought to cost around $2 million- so while the technology is around – it’s not around much as cost prohibits its widespread use.[3] At least the Da Vinci machines cost a lot less than many of the real Da Vinci paintings.

The Da Vinci robots look a little like the robots that build many cars. Articulated arms swivel from a central joint. However there is no welding going on here, it’s a much more precise kind of operation.

To see how precise, I was allowed into their training facility to become surgeon for the day.

No patients were harmed in the making of this film and so I was operating on a tiny display of rubber bands and rubberised sticks. They were only a few centimetres high and my job was to pick up the tiny rubber band and hook it over the tiny stick.

The surgeon, or me, sits across the room from the patient and looks through a video panel at a display, which is magnified many times. I controlled the robotic arms via a few joysticks and foot pedals which allowed me to turned my large imprecise hand movements into very controlled small movements around the rubber bands.

It takes about half an hour to get the basic feel for it – and by then I was getting so confident I felt I could really have a go at a patient. There were no volunteers amongst the crew though so I stuck with the rubber bands.

Technology likes this of course enables surgeons to conduct very precise surgery. But it seems to me the full advantages haven’t quite been reached.

I was sitting just a few feet away from the operating table – but there is no real reason why I couldn’t have been sitting at home controlling the operation thousands of miles away in California.

If that happens, it would open a future in which patients around the world could benefit from surgical skills, not of robots but of human surgeons in different countries, delivered to them by robotic arms but very much dependent on a human surgeon’s skill. That, I think is the real future of the robotic surgeon and his very human skills.

Stuck To A Wall

BIOMIMICRY

Wall

 As I was stuck to the wall in a warehouse on the outskirts of San Francisco, I did wonder what on earth had brought me here.

The answer to that was Janine Benyus. She is the founder of the Biomimicry Institute and is widely credited with popularising the term biomimicry in her book Biomimicry: Innovation Inspired by Nature.

In her book, Benyus suggests looking to Nature as a “Model, Measure, and Mentor” and emphasises sustainability as an objective of biomimicry.

Perhaps the most famous example of man-made technology imitating the processes and ideas of nature is the invention of Velcro.

In 1941, a Swiss engineer named George de Mestral returned from a hunting trip with burs clinging to his trousers and tangled in his dog’s coat. When de Mestral examined the seedpods under a microscope, he marvelled at how they bristled with hooks ingeniously shaped to grasp at animal fur. Eventually de Mestral learned to mould nylon into a fabric studded with tiny hooks or loops that acted like artificial burs. With that he had invented Velcro and changed the world of fastening for ever.

So back to why I was stuck on a wall. Perhaps you have guessed already. To show how effective copying nature can be – we found a funfair ride supplier who had a wall made of Velcro. He put me in a rainbow striped suit also made of Velcro and stuck me to the wall.

The idea was that, stuck there, waiting for the cameraman and director to get their shot, I would think of a piece to camera to introduce the film. I had my notes in my hand and while the crew looked for the best angle I would learn some salient facts. The problem of course was that although I was holding my notes, my arm was stuck to the wall and so I couldn’t get my papers anywhere close enough to my face. So for 10 minutes I stayed glued to the wall trying to attract the attention of the crew, who seemed too busy to notice or hear me.

It certainly left me plenty of time to ponder the power of copying nature. Janine now runs a biomimicry consultancy in which advises companies from around the world on how looking to nature may help them develop new products. Amongst her clients are: Boeing, Colgate-Palmolive, Nike, General Electric, Procter and Gamble and Levi’s.

In this programme we visited Munich University of Technology where they’re trying to develop an artificial skin that has the capability to sense just as much as ours can. The work is part of the Walk Again Project, which helps those who are unable to walk to get back on their feet. The project involves developing an exoskeleton – robotic legs that can help people get mobile. The mechanics are heavy and whilst they enable people to move it’s a very disconcerting experience. These are robot legs not yours and so you can’t feel what you’re doing. The artificial skin could make the technology feel more natural.

The skin is used for two functions on the exoskeleton: first, to provide tactile feedback to the user, so that they can feel “their” foot touch the ground (currently this is relayed to the user in the form of vibrations against the back), and secondly to measure stress for the safety of the user

Each cell contains multiple sensors, emulating the various sensory information of human skin, such as pre-touch (feeling something is close to your skin, but not making contact), light touch, medium and strong touch, vibration, and temperature.

From Munich we flew to Cairo where we visited a team developing tiny robots that swim and that may one-day swim around inside of us in order to deliver medicines.

The microrobots measure just 322 micrometers long, 5.2 micrometers wide and 42 micrometers thick, and their heads are coated with a 200-nanometer nickel-cobalt layer that allows them to respond to a magnetic field.

The problem with most Microrobots is that the battery they need to supply the power is often bigger than the robots. This team has tried to get round the problem by using four electromagnetic coils to generate an oscillating field that was as weak as a refrigerator magnet but strong enough to get the tailed robots to waggle and swim.

The inspiration for the design came from looking at sperm. They copied the design because they found it is very efficient in terms of traveling through liquid.

Working for a science and technology programme we often trumpet the designs of very clever scientists. It’s good therefore that in this episode we give credit to the greatest laboratory of all – nature.

The Money Maker

Water is the liquid of life. We cannot live without. It is a life giver and a life saver – and yet we increasingly hear talk a water crunch. Increased global populations and demand from agriculture already mean that some people around the world are now facing water shortages and many people feel in the future we will all be living in a much thirstier world.

Although the problem is now most keenly felt in the poorer places in the world, I’ve headed off to one of the richest – where exists the rather trendy headquarters of a company which is trying to help those in most need.

Martin Fisher is the CEO of Kickstart. He spent decades in Africa working on community projects –many involved improving access to fresh water.

Standing in his New York office, what I am looking at – is rather like a heavy metal version of a gym Stairmaster workout kit. It is a bit of simple tech – using a tried and tested reciprocating pump valve that relies on suction and pressure – powered by humans.

The KickStarter

Its purpose is to help farmers irrigate their land. One person does the work out on the foot operated pump – the other takes the hose. The more you walk, the more water you pump.

It looks simple and indeed I was surprised this isn’t part of the basic agricultural tools many farmers must already have. But even today in many poorer parts of the world, traditional agriculture still relies on regular rain during the one or two rainy seasons. If it doesn’t rain – the food doesn’t grow.

When you can only grow food when it rains – there’s an economic problem as well as an agricultural one.

When all of the farmers pick their crops at once, the market becomes flooded with produce during certain months and as a result at the very time farmers have something to sell – the over supply of produce forces prices down.

It’s a painful Catch 22. When prices are high – farmers have nothing to sell and when they are low farmers have too much produce.

Seasonal farming can leave communities stuck in a cycle of poverty and hunger.

KickStart introduced human powered pumps for irrigation in 1997 to address this problem. The pumps are sold for between US$35 and US$100. KickStart estimates that farmers using irrigation during dry seasons increase their annual incomes by over US$1000. It’s why they’ve called their foot pump – The Money Maker.

As I hear the trucks of New York delivering produce to warehouses, as we hear planes fly overhead and as we sip on coffees which no doubt would cost more than the average weekly wage of many of those we are talking to – the simple bit of kit in front of us looks rather unimpressive.

But KickStart estimates that its irrigation pumps have brought over US$100 million to rural communities throughout the developing world. They believe this is helping solve not just a water issue, but it’s alleviating hunger and helping economies at the same time.
