À l’Estacade

Chataignes, noix et potiron
Les haricots selon saison
Pommes de terre, fenouil et blettes
Une aubergine et trois courgettes
Des saucisses et saucissons
S’il y en a des champignons
Quelques tranches de jambon cru
Et de l’ail car il n’y en a plus
On mange toujours de produits frais

Smart Grids

Today, at the Copernicus Institute symposium on "Making science work for sustainability," I quickly learned about smart grids in the smart grids parallel track. "What are smart grids?" was the question moderator Frits Verheij (DNV-GL) kicked off the day with. "A buzz word? An industrial technology push? Or the solution to saving the planet?" Eva Niesten (Utrecht University) did not have the answer. Her review of the literature concluded that there's "consensus that there's no consensus" on the definition of a smart grid. Technology patents with a smart grid label are currently exploding, Floortje Alkemade (Utrecht University) found. And business models are still predominantly theoretical. In simulations by Wilfried van Sark (Utrecht University), smart grids can provide great flexibility services. And Elwin ter Horst (Smart Grid Value4All) showed how smart grid pilot projects yield promising results in the real world but run into technological, economic and institutional barriers.
From these presentations, a picture of the smart grid as an emerging concept emerged. Exciting times! A lot of experimenting is going on, which is bound to bring forth the elements and architecture that will define the smart grids concept. In the mean time, however, Ronnie Belmans, executive director of the Global Smart Grid Federation, which was established to "bring together Smart Grid initiatives from around the world," had jumped ahead and pleaded for "standardization" and "interoperability." Would that not be a bit too fast, Mr. Belmans? Would it not kill the explorative phase smart grid development is still in, which this day so clearly showed, rushing into a lock-in in inferior technology?

Springtij: energie & klimaat

Van donderdag 25 september t/m zondag 28 september jl. vond alweer de 5e editie van het Springtij Forum plaats op Terschelling. Vier dagen gesprekken over de New Green Frontiers, in wetenschap, techniek, beleid, bedrijfsleven en inspiratie, van voedsel tot financiën, van energie tot biodiversiteit. Alle zintuigen en dagdelen deden mee.

Ik volgde de sessies bij het thema energie & klimaat. Daar ging het er scherp aan toe; men aarzelde niet direct de centrale dilemma's op tafel te gooien. Frans Rooijers, Piet Briët en ik hebben de discussies in een column proberen te vatten, bij het slotdiner voorgedragen door Frans.

Column Energie en Klimaat:

We mogen niet doemdenken, maar leuker kon Leo, onze IPCC-man, het niet maken: we zijn op weg naar +4ºC. Codetaal voor voedsel- en watertekorten, migratie en conflicten, en een zee die meer neemt dan ons lief is. En die gevolgen staan al op de balansen van de fossiele energieproducenten als bewezen voorraden olie, gas en kolen. Driekwart van die fossiele voorraad mag niet als CO2 in de atmosfeer eindigen als we de opwarming onder de 2ºC willen houden. En dat willen we, zegt ook de hele energiesector op Springtij. Energietransitie moet, natuurlijk. Waarom gaat het dan zo langzaam?....Lees verder op de website van Betty de Keizer.

Rigor, relevance, value

In a lecture on peer reviewing, I was taught that, as a reviewer, I should comment on the scientific rigor, relevance, and value of the manuscript (I'm talking about studies in management science, not natural science). Very well, I thought, the 'relevance' of course refers to whether the study addresses an interesting topic from a practical point of view. But, no no, the 'relevance' was meant to be purely scientific: does it address a gap in the literature? Then it must be 'value' that refers to the study's interest to the real world, right? Wrong again. Value means the kind of contribution made to the literature. Wow, so none of the reviewing criteria is concerned with actual real-world relevance! Isn't that a guarantee for academia disconnecting itself from the real world? Or would such a criterion be a harmful constraint on scientific inquiry, and is the disconnect prevented through other mechanisms that may be temporally separated (through research budget allocations for instance)?

La Marmotte, encore

A marmot whistles from the grassy alpine slope to my left, but I'm focused on my cadence and the stone building in the distance that marks the top of the Col du Glandon. Barely 8:30 in the morning and already 90 minutes into La Marmotte GranFondo, together with 2000 others. It's the yearly cycling race for amateurs that passes three legendary mountain passes before finishing with the (in)famous climb to Alpe d'Huez. This morning, remnants of last night's cloud deck mixed with early rays of sunlight make for a stunning scenery to climb through. In about 10 minutes I will reach the top of this first of four climbs and hope to find Merijn there healthy and happy. At 6 in the morning, I had dropped her off at the parking lot at the foot of the mountain with her bike and four bottles of sports drink. She would climb up before the riders, carrying the weight of the bottles on her back, in order to resupply my friend Mark and me when we crest the col during our race, which started at 7 AM.
Suddenly, I recognize the rider next to me. It's Henk, the Dutch guy I rode to the finish of the Vercors Challenge with, about 5 weeks ago. Would he have made the 1000 km trip to the French Alps again, just to participate in this race? How many times a year would he do that? What would he do for a living? He could be a lawyer, or a system administrator, or the owner of car dealership maybe. Instead of asking, I focus on dropping him. Why? Why is going fast always trumping the opening of the senses to all that's there to be seen, heard and smelled? The scenery is stunning, the weather nice, the people diverse. Could it make more sense to maximize one's time on the course rather than minimize it? Maybe, if people wouldn't immediately ask your time and rank when you tell them you did La Marmotte. Maybe it’s that bike racing brings a new social order. On the bike, social differences are neutralized and replaced at the finish line by the classification. From that perspective, it would be cowardice not to race, an arrogant rejection of the new order. And what about the joy of racing, the great feeling of satisfaction that is waiting for you at the finish line and which is strongly correlated to the amount of suffering endured to get there? The mountains won't go anywhere, I can devote them my proper attention some day when the clock isn't running. So, let's drop Henk if we can.
Unfortunately, my legs feel mediocre. I have more difficulty pushing the gears than I remember from last year and something in my back seems to block my left leg a bit. Merijn's waving and smiling. Two fresh bottles, a jacket and a kiss and down it goes, into the treacherous descent into the Maurienne valley. In the valley, I'm thinking I ended up in a good group to cover the 25 km traverse to the next col with. But the cooperation in the group is getting progressively worse. One frustrated rider starts screaming at another, but he is complaining to the wrong one, a strong one, instead of the short old Frenchman who, knowingly or not, is constantly sabotaging the echelon and deserves a . As a result, I'm spending much more energy on this flat part than I planned to. As soon as we hit the bottom of the Col du Télégraphe, the group is back to a mere swarm of individuals. The next 75 km over the Col du Télégraphe and the Col du Galibier back to the foot of Alpe d'Huez pass rather quickly. The weather is excellent: neither warm nor cold, some sun, some clouds, but no rain. When I hit the bottom of the climb to Alpe d'Huez I'm glad to discern Petra, Mark's wife, standing beside the road with her pregnant belly of 8 months, holding out a fresh bidon. We exchange bottles as if every second counted, and I drop all excess weight (jacket, arm warmers) at her feet. The speed I have to settle for I find a bit disappointing at first. But as I seem to be leaving behind most of the riders of the group I'd been in in the descent from the Galibier, I cannot be doing so bad. In corner #7, the (in)famous "Dutch corner,"  a bit past halfway up, there's Merijn again! She's holding out a bottle of refreshing water this time, which I partly pour over my head. I control my pace and manage to keep it steady until the top. I've tried a bigger gear, but the effect on my speed was zero. Coordination is giving in on the last steep straight, so this must be all I have today, the legs are done. Behind the finish line I suddenly find me and my salty face standing still in the midst of the colorful fair that is the finishing area in the heart of the ski resort. The abrupt change from a pressurized racing environment to a slow-paced holiday atmosphere confuses me.
According to the official time, I needed four minutes more than last year to finish the race and ended up 159th in the classification. Surprisingly close! All day I'd been disappointed about the speed on the display of my odometer; I was convinced that last year I was significantly faster. Last year, though, I didn't have an odometer, and with only four minutes difference it's impossible that I was really noticeably faster last year. So this innovation had been feeding me negative energy all day, for nothing! I can't believe I spent a good seven hours in the saddle, though. Normally, that would be a very long day, but today they passed very quickly. The loop the parcours makes is awe-inspiring on a regular day, but in an event like this, the magnificent mountain tops and endless roads seem to shrink to a mere backdrop for a cyclists' playground. Come back again tomorrow and the rocky heights will demand your renewed respect.
After finishing I feel a bit dizzy, but the feeling quickly fades. In the finish area I'm looking for Mark, but he's nowhere to be found. Last year, he was waiting right there behind the finish line. What happened? He was racing ahead of me from the bottom of the first uphill, and I did not see him again after that. Then, after about ten minutes, he suddenly shows up next to me, looking exhausted. Sweat drips from his glasses, leaving a trace of salt. He obviously just finished and told me he had a puncture near the Col du Galibier. As he was descending, in the first corner his bike almost slid from underneath him. He stopped, was freezing, but was lucky to find a kind spectator who happened to have a spare tube and CO2 cartridges. The guy replaced the tube and reinflated the tire while Mark was shivering. It had cost him at least 15 to 20 minutes. The malheur had cracked his morale and confidence, but he got back into his rhythm on Alpe d'Huez.
Mixed feelings after the race. I would love to race again next year, faster. But the time and energy that went into preparation was costly, in many ways. What would it take to get fit enough to feel strong, ride with grace, enjoy the effort, the scenery, and sometimes the game? Even more training, possibly. Should I just let go of the racing and maximally appreciate the opportunities the event has to offer. For that, though, I don't need a chip for timing and had better do a randonnée, together with the other old men.

5, 2, 0, Hoppmann
Focus, focus, focus
What on? Hocus pocus
No plain vanilla company
Shedding light on LED
MaxQDA, R, Stata

Heavy duty agency
Outrageous EV subsidy
Mountain exploration
Barrier exploitation
Niche, TIS, institution
Incumbent dissolution?
Field configuring karma
Frame disruption drama
Cognitive hypotheses
Irish offshore qualities
Is Oman transitioning?
I’d like to do some modeling!

Wubbo Ockels, gone too soon

Wubbo Ockels, 1946-2014 (Photo: HP Photography)
A cruel thing about cancer is its randomness. There's no justice, no explanation. The tumors are like snipers that randomly seek out their victims. Everyone a target. You feel it when a dear one is hit, like happened last year when the news got out that Wubbo Ockels was diagnosed with an aggressive kind of kidney cancer. Two years the doctors gave him - one year it was. Today, after a year of relentless fighting, his body could no longer. My thoughts go out to his wife Joos and their children and grandchildren.
In 1985, Wubbo became the first Dutch astronaut, flying aboard the Spaceshuttle Challenger. His space flight launched him onto the national stage. He never left. He leveraged his fame to advance the issues he deeply cared about: sustainability and new technology. It never tired him to explain how his experience in space had made him realize that his mission was on the ground. From space our planet looked so beautiful yet so vulnerable. Looking down from the shuttle it sank in that the earth is our only home and that it is habitable only thanks to an atmosphere that, as seen from space, is ridiculously thin. There is no escape planet. Earth is our spaceship and we are all astronauts, so we’d better not break it. That became his mission, which he pursued until this day he died. Too soon for all of us.
Wubbo displayed an uncommon kind of optimism and drive to act, which, I think, he recognized in young people much more than in adults. He had a strong love for and believe in technology. Young people developing spectacular sustainable technology, that is how Wubbo thought the planet was to be saved. And that is how I met him.
When I was a student at Delft University of Technology, studying Aerospace Engineering, Wubbo was a (the part-time) professor and adviser to the Nuon Solar Team, a group of students that had just won the World Solar Challenge in Australia with their self-designed and self-built solar-powered race car. I joined the project for its second campaign to develop a brand new car with a brand new team. Afterwards, Wubbo became my thesis supervisor and enabled me to write it on the solar car project. The collaboration has impressed me indefinitely. His drive to win, his intelligence, and the calmness to manage crises I had never experienced before. When he couldn’t make it to my graduation ceremony, he made a little video clip in which he spoke to me sitting in our solar car and dressed in his professor's gown. It made me feel proud. When a few of the solar team had the idea to take the car on a tour through Europe, from Greece to Portugal, Wubbo made it possible for us to work on it. He helped to attract sponsors and arranged assistantships so we could pay our rents. At one point, the Austrian road authorities were refusing to grant permission to drive on their roads with the solar car. Wubbo then picked up the phone and called his well-connected Austrian astronaut friend, to explain what was the problem. Shortly after we got the OK to drive in Austria and would even be escorted by police into the city of Vienna.
The solar team now has completed seven campaigns and many parallel initiatives have sprung from Wubbo’s mind, always revolving around young people and sustainability. Solar powered boats, a super fast electric bus (Superbus) and an energy self-sufficient yaught to live on now grace the roads and waters. His innovative ‘laddermill' wind power concept is in development. Ironically, when the system’s abilities were demonstrated by making it power an open-air performance of the Jan Akkerman band, it weren’t the energy companies that showed interest in the system but bands from all over the world that wanted to use it for their own gigs!
Over the years, Wubbo has grown a small army of techno-entrepreneurs, instilled with the drive to make a difference and the conviction that they can do it, because they have seen it and they have done it. The best thing they can do to remember Wubbo is to continue his work, to do what he has always done: go create the solutions for a sustainable tomorrow and have fun doing it.
