Peinture thermoélectrique : quand nos murs produisent de l'énergie

Peinture thermoélectrique : quand nos murs produisent de l'énergie | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

 En été, la température d'un mur extérieur peut monter à plus de 50 °C.

Si nous appliquions de la peinture thermoélectrique sur les murs de nos maisons et de nos immeubles, nous pourrions récupérer et transformer d'importantes quantités de chaleur en électricité », explique Jae Sung Son, chercheur à l'Ulsan National Institute of Science and Technology (UNIST, Corée du Sud).

Avec son équipe, il vient en effet de développer un matériau thermoélectrique aux propriétés se rapprochant de celles de la peinture liquide.

Cities are the New Nations

Cities are the New Nations | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

In the medieval period, empires battled and colluded with each other in the quest for land. The resulting system, in which nations became the main actors on the global stage, is perhaps the one most of us know best. But it’s changing.

We’re now moving toward a new era where insular, political boundaries are no longer as relevant. More and more people are identifying as “global citizens,” and that’s because we’re all more connected than we’ve ever been before. As a result, a “systems change” is taking place in the world today in which cities—not nations—are the key global players, argues Parag Khanna in his new book, Connectography: Mapping the Future of the Global Civilization.

A very, very inspiring and thoughtful publication !

Philippe Drouillon's insight:

Installées sous la mer, des sphères creuses se vident ou se remplissent d’eau selon que l’on a besoin de stocker ou de réinjecter dans le réseau l’électricité produite par des éoliennes. Un test avec une sphère de 3 mètres de diamètre - à l’échelle 1/10ème - vient de démarrer dans les eaux du lac de Constance.
Le nouveau système reprend le principe du stockage d’électricité par pompage utilisé sur les barrages hydroélectriques : l’électricité à stocker sert à pomper de l’eau vers un réservoir haut, tandis que le flux d’eau libéré en sens inverse permet de faire tourner une turbine – et de récupérer l’électricité stockée.

Why the changing nature of work means we need a Universal Basic Income

Why the changing nature of work means we need a Universal Basic Income | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

We have a crisis of work. The secure, well-paid jobs of the past — many of them in manufacturing — are disappearing.

What is replacing them is insecurity and uncertainty. Low-paid, part-time, temporary and seasonal work. The so-called “sharing economy”, where people rent out their possessions for a pittance. The “gig economy”, where people are paid performance by performance — or piece by piece.
Moreover the forthcoming technology wave will highlight that it is economically inefficient for humans to do jobs that could be better done by machines, and it is a shocking waste of human talent. So bring on the robots, and let the humans go to the pub. That’s where new ideas are generated, new connections made, new enterprises started.
If we are to embrace technological change, we need to take seriously people’s need for a financial “anchor”, a rock, a safe place, an income which will ensure that they can survive regardless of the work they do. And security of income does not have to come from work.

How (and why) we created EXP – Enspiral Tales | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

This article is about three things: firstly the challenge of earning a living in an increasingly volatile economy, secondly the challenge of finding work that is meaningful and enjoyable, and thirdly doing all this in a way that creates enough time and energy to contribute to the other things that give my life meaning.

This is what all EXP, a venture that span off Enspiral, is about.

How to win back the city: the Barcelona en Comú guide to overthrowing the elite

How to win back the city: the Barcelona en Comú guide to overthrowing the elite | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

In May 2015, the citizen platform Barcelona en Comú (Barcelona in Common) catapulted Ada Colau into power as the city’s first female mayor.

Ten months earlier, the group didn’t even exist.

With no money and little experience, just how did they wrest the city from the entrenched political caste that had been running it for the past 40 years?
The group has now produced a step-by-step explanation – How to Win Back the City en Comú. A new documentary, Alcaldessa (“Mayoress”), by the Catalan director Pau Faus, promises further insights into how this revolution in urban governance came about.

6 Socially Responsible Food Companies That Deserve Your Business

6 Socially Responsible Food Companies That Deserve Your Business | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

A whole range of certifications give shoppers a clue which food products on grocery shelves are good for the earth, animals, or producers. Labels like USDA Organic, Fair Trade, and Best Aquaculture Practices give discerning eaters important information about what’s really inside a package.

While most of these certifications vouch for the bona fides of the food items themselves, there’s another certification that will give you a sense of the values and practices of the companies themselves.

Companies certified as B Corporations by B Lab are officially taking social responsibility into account.

These companies have decided to consider the greater good alongside shareholder profit when setting business priorities and practices. According to B Lab, these companies “meet rigorous standards of social and environmental performance, accountability, and transparency.

Turning plastic waste into roofs in Burkina Faso

Turning plastic waste into roofs in Burkina Faso | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

A true environmental plague in Africa, plastic wrappings are everywhere. It seems impossible to stop their consumption overnight or the habits of populations that go with them.

Calvin Tiam, Cameroonian engineer in industrial process technology and renewable energy, on the contrary, sees an opportunity to produce sustainable materials with local raw material and cheaply.
A large majority of homes in Ouagadougou are covered in corrugated iron. A makeshift roof, ill-adapted to the Sub-Saharan climate, that produces more heat. As a result: inside the homes, the temperature easily reaches 50°C and this heating discomfort is detrimental to inhabitants’ quality of life.
Calvin Tiam develops a roof coating made from used plastic. Made locally, this material considerably recycles polyethylene plastic waste. One square meter of this coating represents around 10kg of recycled plastic, thus a decrease of 9kg of CO2 equivalent of greenhouse gas in nature.

How H&M, Marks & Spencer and Zara are fashioning change

How H&M, Marks & Spencer and Zara are fashioning change | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

Transforming an unsustainable global supply chain can seem daunting. As much as a single company may be committed to change, it’s almost impossible to do it alone.

There is a need for peers and competitors to become colleagues and mentors to enable all. Collective action possesses a raw power that enables us to imagine a different reality. And once that happens we put solutions squarely within the realm of the possible and probable.

That is exactly what happened last week in New York City as our environmental nonprofit Canopy, along with H&M, Inditex/Zara, Stella McCartney, Marks & Spencer and Eileen Fisher, welcomed representatives of 87 global fashion brands and retailers for a day-long summit to strategize conservation solutions for the world’s endangered forests.

What’s the link between forests and fashion? The immensely popular fabric rayon (otherwise known as viscose, modal or lyocell) has become a major driver of logging globally, with more than 120 million trees disappearing into the fabric annually.

Mexico's Indigenous Groups Start Telecom Co-op after Being Refused Service

Mexico's Indigenous Groups Start Telecom Co-op after Being Refused Service | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

Villa Talea de Castro is a village in Oaxaca, Mexico with a large indigenous community.

Prior to 2013, the 2,500 inhabitants of the village had limited phone service via landline phone booths. Large cell phone companies refused to provide service to the area.

So the community partnered with NGO Rhizomatica to install its own local cellular network that provides unlimited local calls and messages and low-cost long distance and international calls.

“La Fab City, c’est bien plus qu’une ville remplie de Fab Lab »

“La Fab City, c’est bien plus qu’une ville remplie de Fab Lab » | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

Comment faire de la ville un espace tout à la fois auto-suffisant et connecté avec le reste du monde ? C'est l'ambition du programme Fab City initié par Tomas Diez.

La Fab City, ville localement auto-suffisante et globalement connectée, invite à repenser l’impact de la fabrication numérique au-delà du Fab Lab, pour relocaliser la production industrielle, alimentaire et énergétique sur le territoire urbain.
Le Fab Lab est le socle d’une vision ambitieuse qui consiste numériser et relocaliser la production dans son ensemble. C’est un terrain d’expérimentation où l’on prototype de nouveaux modèles de fabrication distribuée, une nouvelle relation entre l’acte de produire et celui de consommer. Les citadins peuvent désormais fabriquer ou faire fabriquer des objets à proximité de chez eux, plutôt que d’acheter des produits tout faits fabriqués en Chine.

Dans la fabrication numérique, le plus important n’est pas tant la technologie en tant que telle, mais le changement culturel qu’elle induit.

Philippe Drouillon's insight:

À Albi, les élus de la ville viennent de se fixer un objectif aussi concret qu’utile et ambitieux : permettre à tous les habitants de se nourrir de denrées produites dans un rayon de 60 kilomètres autour de la préfecture tarnaise à l’horizon 2020 !
Avec la mise en place de circuits courts, la ville d’Albi vise trois objectifs : réduire l’impact carbone lié aux transports de marchandises, sécuriser les approvisionnements en cas de crise alimentaire (actuellement, les stocks disponibles sont estimés à 5 jours seulement) et assurer une meilleure qualité des produits consommés.

Un capteur pour économiser l’eau dans l’agriculture -
Philippe Drouillon's insight:

L’eau se raréfie et devient le nouvel enjeu autour duquel se redessine la carte du monde.

Miser sur la rationalité de l’utilisation de la richesse hydrique est un des moyens pour assurer aux pays une sécurité alimentaire. Et c’est là que la technologie intervient pour fournir les moyens de rationalisation de l’utilisation de l’eau dans le domaine agricole.

L’un de ces moyens a été inventé par la firme américaine Edyn, conceptrice du «système de jardin intelligent, qui surveille et suit les conditions environnementales», contrôlant à distance le niveau d’humidité du sol et l’eau utilisée pour l’arrosage,

Blockchain et énergie solaire veulent promettre ensemble une "révolution énergétique"

Blockchain et énergie solaire veulent promettre ensemble une "révolution énergétique" | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

Des projets associent de plus en plus panneaux photovoltaïques et blockchain pour permettre d'autoproduire et de consommer sa propre électricité.

Ainsi, par exemple, chez Sunchain, la technologie Blockchain est utilisée comme un registre.

Elle permet de certifier l'origine de l'électricité verte de façon entièrement automatisée. Un capteur installé sur les panneaux solaires émet les informations sur l'énergie produite. Que l'électricité d'origine photovoltaïque soit directement consommée ou vendue, la blockchain enregistre son évolution. L'avantage : les informations sont distribuées chez chaque membre de la blockchain, d'où la transparence du dispositif. Et son inviolabilité, car il est plus aisé de hacker une base de données centralisée que des informations sécurisées distribuées en plusieurs endroits.

A quoi s'ajoute l'indépendance du système vis-à-vis de tiers, type certificateur ou notaire, pour valider les échanges. Un élément crucial des business model de ces start-up qui misent sur des coûts de transaction très peu élevés grâce à ce système informatique.

Au Maroc, "l'eau solaire" pour faire aider les paysans

Au Maroc, "l'eau solaire" pour faire aider les paysans | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

Perdu dans la montagne en plein pays berbère, à une quarantaine de kilomètres des côtes méditerranéennes, Tafoughalt vit essentiellement d'une petite agriculture vivrière et de ses cultures en terrasse.
Isolement, exode rural, champs abandonnés, érosion des terres... le cycle est classique, avec toujours en arrière-plan les difficultés d'accès à l'eau.
Avec la sécheresse et le réchauffement, la pluie est de plus en plus aléatoire. Quant au carburant pour les générateurs,
le prix a été multiplié par trois, passant de 10 euros le bidon de 30 litres à 30 euros.
Avec le soutien de bailleurs de fonds internationaux et locaux, deux pompes à énergie solaire ont été installées dans les montagnes de Tafoughalt.
Le principe est simple, le matériel d'un entretien aisé et d'une longue durée de vie, le soleil est source d'énergie stable, fiable, propre, inépuisable, sans pollution ni répercussion sur la santé humaine.
Avec un système de rotation le prix de l'heure d'irrigation était de 50 dirhams (5 euros), il est maintenant à 12,5 dirhams (1,25 euros), quatre fois moins cher!.

How a rabbit and a cube of butter helped us run our biggest workshop yet! | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

Conducting a co-creation workshop with 100 participants is quite a challenge !

While standard workshop planning emphasizes the participant’s experience, this situation requires to really focus on the facilitator’s experience as well.
Through this process, eight tips for conducting a workshop can be considered :
1. Create intentional pairs of facilitators
2. Give your facilitators a playbook
3. Practice, practice, practice
4. Set the ground rules like the "rabbit hole" and "No butter" rules
5. Give your team a uniform
6. Put your tools in a toolbox
7. Use a sign to organize participants
8. Create a productive space

OpenCollective - A New Form of Association, Transparent by Design

Philippe Drouillon's insight:

An Open Collective is a group of people with a shared mission that operates in full transparency. Everyone can see how they receive or spend money.

The Open Collective initiative is aimed at allowing these organisations to :

  • Set up a page to collect membership fees or donations
  • Let their members submit expenses and reimburse them with a click
  • Give everyone visibility on its budget

In a "classical" organization,  Open Collective can be used to empower local chapters to raise money locally and have their own budget.
Open Collective is perfect for any side project that is not for profit. Side projects should be fun. You shouldn't have to worry about creating and maintaining a legal entity, doing bookkeeping, etc. as soon as you need to collect money to reimburse your expenses. Open Collective is ideal for meetups, open source projects, parent associations, neighborhood associations, clubs, unions, movements, non-profits, business incubators, etc.

They took a very ‘lean startup’ approach, creating a useful minimum viable product as quickly and cheaply as possible, and then iterating on it based on real user feedback.

They got off the ground with no capital at first. Then they quickly started generating revenue from consulting services, working with organizations who want to collaborate and do effective consultation but need help.

Fabcity Dashboard, for today’s labs and tomorrow’s cities

Fabcity Dashboard, for today’s labs and tomorrow’s cities | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

The Fabcity Dashboard, proposed by Tomas Diez, director of Fablab Barcelona, is part of the Fabcity initiative.

The idea is to open the dialogue on the role of labs (fablabs, hackerspaces, biolabs, livinglabs, etc.) in the future development of cities (envisioned to be fabcities) on a global scale.
This project is based on the fact that cities will soon be facing a number of risks related to climate, energy, the economy and demographics.
The hypothesis at the heart of the Fabcity Dashboard is that fablabs represent an avant-garde movement for new citizen-oriented, eco-conscious models of development.

Here,  the potential foundations for the cities of tomorrow—cities based on the collaborative and sharing economy, as well as decentralized, relocalized forms of agricultural and industrial production are tested on a micro scale

Is 3D Printing a Threat to the Workforce? 6 Questions & Answers

Is 3D Printing a Threat to the Workforce? 6 Questions & Answers | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

Automation, AI, collaborative platforms, freelance work, uberization, on-demand consumption, outsourcing, globalization…

As we are bathing in what is often called Industry 4.0 or The Fourth Industrial Revolution, many factors seem to be on their way to making work as we know it obsolete. Many fear that their jobs will be replaced by robots in the next few years, and that the only way to keep the population from suffering from the upcoming increase of unemployment is to adapt to a jobless (or job-scarce) economy, thanks to, for example a universal basic income system.

Our question today is: is 3D printing one of those “threats to the workforce”? Are 3D printers coming for our jobs? 6 questions and answers to try and make it all clearer.

The sharing economy: Using business as a force for good

The sharing economy: Using business as a force for good | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

As we race towards reaching nine billion people on the planet in the next few decades, it is clear that there are not enough resources to support us all and fundamental changes need to be made. The positive news is that the sharing economy has allowed us to find innovative ways to share resources with each other, helping us address some of the environmental and social problems we face.

Although half the population in the US owns a power drill, it is used on average only six and 13 minutes of its lifetime. Does it really make sense for each household to own a drill when it will probably be stuck in the back corner of your drawer? Companies like Nextdoor, Streetbank, and Yerdle allow for you to borrow items from your neighbors, which are much needed solutions when you consider that countries like the UK are running out of landfill space in three years.

Rennes : 210 000 habitants vers l'autosuffisance alimentaire ! | Metamorphosis | Scoop.it
Philippe Drouillon's insight:

L’autosuffisance alimentaire n’est pas une utopie, c’est un objectif réaliste et nécessaire ! Après Albi, la collectivité d'une autre grande ville française, Rennes, a voté le 27 juin dernier une délibération pour un ambitieux programme de transition citoyenne et écologique.
Pour atteindre l’autonomie alimentaire, la municipalité dispose d’un espace de production agricole de proximité estimé à 30 000 hectares. Mais la surface ne fait pas tout.

Les élus ont en effet décidé de mettre le paquet sur le bio, sur l’agriculture urbaine, l’agro-écologie, la permaculture, les Associations pour le maintien d’une agriculture paysanne (Amap), les circuits-courts, l’éducation à l’alimentation saine… et sur la collaboration de tous les habitants !
