instagrid - we are a start-up with new technology for the world's most advanced battery-driven portable power supply. Our products can replace mobile diesel generators, that are still largely used on construction sites, reducing local emissions to zero and improving the air quality in the city. We would like Amsterdam to be one of the pioneering cities to test and implement this new technology.

Demoday #27: What is ethical mobile software for your phone?

We depend heavily on Big Tech companies like Google, Meta, Apple, Amazon, and more. And with your smartphone, there is no escaping them. Even if you don’t use social media, and use anti-tracking software, some of your data will still be shared and sold. This can make you feel pretty uncomfortable. Especially, since most of these tech companies are in the USA and China. This is why, in this session, we worked on the question: Is it possible to develop mobile software which is ethical and functional?
Danny Lämmerhirt from Waag Futurelab works on the MOBIFREE project. This project aims to change the development and use of mobile software in Europe by citizens, businesses, non-profits and governments. In doing so, they want to support the emerging movement for ethical mobile software consisting of organisations that adhere to European values such as openness, privacy, digital sovereignty, fairness, collaboration, sustainability, and inclusivity.
In this session, Danny introduced us to the smartphone they are working on. This smartphone has its hardware from Fairphone (an ethically produced smartphone) and uses a privacy-friendly operating system: Murena. This operating system is an Android fork that doesn’t come with standard tracking software. On top of that, it has an app store with only ethical apps and is connected to an ethical European cloud.
Outcomes
We discussed with the group what values we found most important in an ethical mobile phone when using it for work. The values that were deemed most important by the group were:
- Autonomy: A smartphone allows working wherever and whenever you want. It is an incredibly powerful tool that you can use for so many different things, and it fits in your pocket.
- Independency: We’ve become incredibly dependent on our smartphones. When you lose your phone, you no longer have your money, your public transport card, a map to find the way, etc. On the other hand, this also means that you don’t need to travel with a bag full of tools every time you leave the house.
- Privacy: Constantly being tracked has become normal, but that doesn't mean we’re happy with it. Right now, you don’t have a choice. It would be nice to have a choice, to either pay with your data, or with money.
- User-friendliness: An ethical and privacy-friendly smartphone sounds great, but it also means that you can no longer use many of the apps that you’re used to. Will it still be practical to use? And will it be intuitive? We are all used to a certain way of working and are hesitant to change.
This discussion was definitely food for thought. We all want a more ethical phone, but are not willing to sacrifice much in return…
Are you interested in trying out this ethical smartphone? The MOBIFREE project is currently looking for people who can test this smartphone. They are looking for young adults, civil servants, mobile software developers, and professionals working in humanitarian organisations.

Demoday 27# District heating and resident participation in the municipality of Haarlemmermeer

The municipality of Haarlemmermeer is actively working on the realisation of the energy transition in the municipality by, among other things, focusing on sustainable heat supplies. As part of this, a heat initiative has been started in the village of Rijsenhout (east of Haarlemmermeer). This initiative has not been taken up by the market in the past. This has led the municipality to want to take a more active role in the development of District heating in which resident participation is a crucial factor.
During the Knowledge- and Demodag on 13th of March (2025), Kelly Winters and Sophie Keijzer (Hieroo) led a session with the participants that looked at similar successful processes in the past of realising a heat network. The central questions were: What was the success and why was it a success?
Session structure and focus
During the session, the participants split into two groups. Similar processes were then discussed in the two groups in which the success factors of the realisation of energy transition projects were examined. An important example that was discussed in the session was the Schoonschip project in Amsterdam North. This project is a sustainable initiative in which residents have researched how they can live on the water in a circular and sustainable way. This resulted in a community of 46 houseboats that share energy with each other via a Smart Grid that’s cheaper and more efficient.
Outcomes and insights
During the session, various strategies were discussed to strengthen resident participation and make heat network initiatives successful. The most important points from the discussions are:
1. Composition of the initiator group: A diverse and enthusiastic group is crucial. In the Schoonschip project, the core of the success was a group of pioneers who complemented each other in creativity and expertise. Such a group can also be formed in Rijsenhout if they are properly guided and supported.
2. The role of the municipality: The municipality must be aware of the distrust that residents often have towards government institutions. Using an external intermediary or an independent entity can help to reduce this mistrust.
3. Reward and inspire: One way to involve residents in a low-interest topic such as energy is to reward them. Examples are setting up competitions, the use of ambassadors or energy coaches and the organisation of events. Linking opportunities, for example by combining energy transition with social goals such as combating energy poverty, can also play an important role.
4. Using the right moment: An important lesson from the Schoonschip project is to use external circumstances to arouse interest. A crisis, such as rising energy costs or limited energy production, can turn a low interest topic into a high interest topic for people.
5. Governance and structure: A solid Governance structure is essential. The municipality can play a role as a project manager by setting clear deadlines and formulating requirements. This helps both initiators and residents to keep focus and take steps towards concrete results.
