„Dream together“ is the title of the exhibition of Yoko Ono at the „Neue Nationalgalerie“ in Berlin 2025. The title is an invitation or even an incitement to dream jointly with others. We need to dream of peace on all sides or parties in a war. Start with the dream and then move on to working together on it. The participatory art projects of Yoko Ono are a recurring event in Berlin and at the Neue Nationalgalerie (Cut piece). The installation „Wish Tree for Berlin“ in front of the gallery is popular with visitors who leave hundreds of written wishes to the windy spring days. Origami folding, stone assembling or a simultaneous chessboard playing with all white pieces and fields encourage to imagine a world differently, beyond the treaded belligerent paths. For more inspiration and imagination just continue to the Martin Gropiusbau for more artworks from Ono or just watch the clouds pass by changing the lighting of the olive tree carrying lots of wishes.
Dysprosium 66
Dysprosium figures as Nr. 66 in the periodic table (short: Dy). This metal was given this Greek name, which translates to “hard to get”. Although more common than gold on earth, Dysprosium is part of the so-called rare earths on earth. Since it is very temperature resistant before becoming fluid and at the same time having good isolation properties, for example against radiation in combination with lead, the nuclear energy industry has a definite use case.
Additionally, wind turbines, electric vehicles and some smart phones use these characteristics of the metal only known to us since the late 19th century.
The major exploitation happens in China and, therefore, the recent tariffs have complicated the trading. Prices tend to rise and products that contain Dysprosium are likely to become more expensive. However, there is the other side of the coin, which means recycling and reuse of Dysprosium is also more interesting to companies. Hence, the price increase will likely enhance circularity of the metal from obsolete products into newer ones. In this respect it is good news that smartphones receive longer updates of their operating systems and security as of 2025-6-20 in the EU. This will also reduce the amount of rare earths needed in the production of the rapidly changing technical specifications of smart phones and tablets. Repairing the devices makes more economic sense before “programmed” obsolescence.

Owners Dispute
Renovations of housing with distributed ownerships can be a challenging experience. In Berlin you can find a few places with visible long-term disagreement about what kind of modernization should be done. More luxurious additions like balconies or triple window isolation and so on are sometimes hotly debated and contested in courts. For most buildings you cannot spot disagreements on the outside, but some constitute exceptions to this rule. One size does not fit all preferences. In a metropolitan city there is a place and a space for all such exceptions to the rule and most people after years do no longer think about such kind of diversity in preferences or budgets available for modernization. Cities put our level of tolerance to a continuous test. You probably learn to love this or eventually you leave the inner city. There are subtle differences in urban versus rural lifestyles. In the social sciences we continue to try to understand the attraction of cities as on a global scale millions of people flock to cities.
Housing renovation
The huge amount of buildings that need renovation is a task for each generation. New constructions are relatively easy to realize even to the best available standards. Particularly energy standards asking nowadays for serious isolation of buildings are easy starting from scratch. Energetic renovations of existing buildings are much more challenging and have to take into account the various stages or predilections of previous generations. Repurposing of buildings raise additional questions like transforming a family home into a representative office building. New technologies like fiberglass instead of copper cables or copper or plastic tubes instead of other hazardous materials cause additional costs and worries. The use of asbestos for interiors of previous generations has created the greatest liability for existing buildings. Technological choices of the past and also of the present (heat pump or not) have lasting consequences and sometimes even health effects. To cherish old buildings and styles is a mixed blessing as the renovation of housing confronts home renovators with more tricky challenges than building a new home. Incremental repairs might do the trick rather than all in one go renovation, however, you might enter into a situation when renovations are always on your mind. Not only the times are a changing, but homes are a changing, too.
Design skills
The is a huge B2C or C2B market in connection with home design and adaptations. Nowadays people are inspired by instagram, pinterest, YouTube and TikTok. Additionally, many play around with Apps to create their own images of how they would like to arrange or rearrange their home. Some have taken first steps to include measurements of their home in the design. The compatibility with professional software of the construction sector, however, is a drawback that delays or leads people to go to enterprises that take into account the prior efforts of young lay designers. It is a little bit like an own contribution in home building quite popular among new home builders to alleviate the upfront cash needed for first home acquisition. The younger generation could offer some of their “digital native” skills to bridge the gap in construction and home design. Of course, reworking and precise measurements on the location will still be required as construction has a lot of legal liability issues involved. Cooperation is a form of burden sharing to advance faster and/or with lower costs.
La défense Végétale
Greening a metal and concrete block and buildings is a big challenge. The logic of unrealistic growth and big business has left liabilities for future generations. More vegetation in inner cities is part of our responsibility towards future generations. Therefore, urban planning has started in Paris to get rid of concrete walls and floors.
Eventually the district might have a more human touch which attracts citizens and new businesses and services. The adaptation of the infrastructure to facilitate mobility with bicycles and secured pedestrian paths has started but will take a lot of time before people adopt again these more healthy modes of transport. The big boulevards reserved for polluting transport is no longer adequate in combination with residential living spaces.
It will take a change of a whole generation to accomplish such a fundamental change. The reduced demand for office space due to more employees choosing to work from home contributes to such a change as well. Many other cities go ahead with similar changes (Copenhagen, Berlin). In combination with the „All electric society“ there are fundamental changes at work which will make inner cities more attractive again. Ease of clean transportation and other infrastructure for urban lifestyles ensures that cities remain strong points of attraction. They keep pulling people from nearby and far away towards them, if we like it or not.
Electronics repaired
The all electric society will have a number of consequences. We need to think about durable electronics. Many electronic appliances get broken rather quickly even by normal usage. The task to repair the beloved electronic gadgets of your children or simple electronic household devices reveals the fallacy of the consumerist societies. “Use it and throw it away, if it is not working any more”. This is the standard mantra of our societies. In order to save resources, we have to reuse, repair and re-engineer a lot of electronic devices. So far, the engineering process consisted largely in finding ways to assemble fast and with inputs as cheap as possible. The task of designing products that are repair-friendly, circular and allow to disassemble the product easily is a bit counter-intuitive to the consumerist society. If your juicer lasts for years, you will be unlikely to buy another more fancy one or even a connected one very soon.
Repair-friendly design and assembling will be the next generation products of the all electric society. Plugs, interrupters, relays and electric engines of older devices will be valuable after the original use in a household product, which has seized to function. Many parts can be put to other use. Re-engineering with sustainability in mind has an important function also in the move towards gaining autonomy again. For the repair of electronic devices we shall focus more on fine motor skills of our hands again. The shortages of electronic components to build cars after the Covid-19 crises and the disruption of supply chains for other reasons provide a good lesson to advance faster in the direction of electronics repaired.
Emergencification
Particularly around holiday seasons across the whole year we observe the “emergencification” in modern societies. This not so new trend consists in the strategy to artificially create emergency situations in which it is considered reasonable to ask for higher prices. It appears to be just another kind of a “greedflation”, whereby extra profits can be reaped due to shortages of food or particular forms of energy. Medical services have also pushed for an emergencification of their services due to ever longer waiting queues for appointments and treatments. The strategy here is easily disclosed. (1) You decline any appointment earlier for inspection of cars, heating systems, office equipment or medical check-ups and sooner or later a “planned” emergency will arise, which allows you to charge higher prices than the routine in time appointment or treatment. This makes prevention of more costly interventions far more difficult. In sum, the costs to society as a whole rise by the simple way of emergencification.
Even using a repair platform, we did not receive a single offer for a more lengthy and costly repair of my 10+ year old car. Hence, we just wait for a breakdown with more serious and costly consequences. Unfortunately, the same holds true for many medical services. If you no longer manage to assure a timely consultation you are more likely to go directly to the emergency services of a hospital. This is then the costly, but only alternative left to you. In the artificially created emergency you have little room for negotiation and a choice of different offers and conditions. It is a shift in negotiation powers to the service provider. The emergencification creates a price inflation of a specific kind. Worryingly, this kind of inflation is well beyond the normal statistical measurement of inflation national statistical offices observe. In addition to the much debated “greedflation” we should deal with the emergencification as an additional price mechanism. Just ask about examples among your friends or in the neighourhood whether they have lived through an example of emergencification. The stories are abundant and full of surprises. The example I heard: “birth and death, both come as a surprise or emergency, and yet we have the whole life to prepare the latter one”.

2P2R
2 Pinot 2 Riesling. That could be the long version of 2P2R. However, this far from (politically) correct. The not-joking scientific medical journal “The Lancet” (Vol.401 Nr 10391) has next to the article on “Laughter is the best medicine” coping with trauma, the serious matter of how best to deal with pandemics. Remember 2P2R as the important lesson from the pandemic. Prevention, preparedness, response, and recovery (2P2R) are key. And don’t forget about primary health care or essential (medical and other) workers. This is, in short, the message from Arush Lal and Nina Schwalbe (Paper Link). Lots of social topics involved in this correspondence from the authors. Prevention is a big issue and, as in the health system, fighting continuously for sufficient resources. Prevention is in most cases less costly than curing a disease. Preparedness has direct costs. Masks and ventilators need to be produced, stored and monitored in their functionalities. Response has to be immediate, masks in China a important but do not allow us to respond fast to local emergencies. Recovery can be long and costly as well, just as we learn from Long-COVID patients.
Now we need to define properly what is included in primary health care. Medical doctors, nurses and technicians of hospitals have to reach patients and hospitals in pandemics or need child care, food etc. and, maybe, also laughter to avoid trauma. Remember 2P2R, but best in company with your loved ones, but not on your own.
Repair 3
Repair is our new mantra. Think of repairing in all domains as of now. Nature is showing us the way how to repair in many ways. Culture is also embracing the shift towards repairing as caring. If we really care about our planet, and there is no planet B, we shall have to repair in many more domains. We are used to repair bicycles, cars, roofs, windows etc. Repairing is never boring. You can improve the performance of a device or building by repairing it, even with relatively small budgets. Isolation of buildings is a good example of investing in upgrades through repairing. Rather than throwing away a functioning heating system repairing it with an energy saving device is enhancing its performance and produces fewer emissions in the short run. Heat pumps are the way forward for new installations. Shifting a sector, heating with gaz, to ensure longer lasting repair and improve options would save a lot of raw materials and CO2 as well. The construction sector has repair work almosts in its DNA, the energy sector will have to make that shift as well. Dare to repair.
Repair 2
Ever since the visit to the exhibition “Care, Repair, Heal” at the Martin Gropiusbau in Berlin the image of flying protheses rests with me. Repairing the human body is feasible in many fantastic ways. The inner wounds, however, are less visible and sometimes hurting even more. In recognition of the thousands of victims again in the Russian war on Ukraine’s territory and the atrocities causes by mines to injure humans, we have to assist in caring, repairing and healing. This has not changed since the Great War or the Nazi-induced mass murder and mutilations. Humanity is unable to bann such landmines despite international conventions trying to achieve this.
The strong image produced by the protheses as clouds in the sky (Kadar Attia) remind us of the lasting effects of war. Images we had associated with the mutilated soldiers and civilians of the 2nd world war, many still around us in the 60s or 70s, are coming back to Europe. Writing about the 20th century, Aurélien Bellanger described in words a similar traumatising vision of flying protheses in his story of the lonely poet and philosopher. We cannot repair history, but we can work towards reducing useless additional suffering. It is part of the absurdities of our world that technology has created masterpieces to assist us and reduce suffering, but at the same time technology is applied to create the worst suffering as well. Rather than thinking of this relationship as 2 sides of the same coin, I prefer to hope for dialectic evolution towards a better synthesis solution using enforceable international law. Yes, I still have a dream! …
R for Repairing
Without noticing for many people, we have shifted into the repair mode. Our planet needs repair work. Well beyond the less plastic, CO2, less oil, gaz and pollution in general, we have to actively repair what we have damaged, certainly since the industrial revolution. With nuclear waste we have entered into a phase, in which repairing is not really feasible. Areas around Tschernobyl and Fukushima speak for themselves. However, we seem to leave the repairing to future generations. Whereas for us currently it is an option, later on it will be an obligation.
The bionic interest has already turned to the Axolotl and Polycarpa mytiligera. Both species can repair themselves after the loss or a malfunctioning part of their body. Rather than producing externally, growing the spare part is a promising healing device. Nature provides many fabulous insights, if we were able to preserve the biodiversity. Repairing biodiversity is difficult, impossible for lost species which we do not even really know. Start to repair and build awareness that repairing can be fun. Beyond the gender stereotypes, women repair cars, men repair clothes, we have to learn from each other how to use our repair knowledge for many other things and devices. This applies even to our social, legal and economic systems.
In addition to reimagining, we need repairing everywhere. I have lots of stuff to repair at home. When do you start repairing? Welcome to the next trend: the joy to repair, repairs even joy.
