πŸš²πŸ“ From ideas to action: the SmoothieBike project is officially rolling!

Over the past weeks, Engineers without borders Luxembourg has started bringing the SmoothieBike initiative to life together with the children at Day Care Arcus as part of the national BNE – β€œBildung fir Nohalteg EntwΓ©cklung” programme.

What began as a broken bicycle is gradually transforming into something much bigger:
✨ a hands-on lesson in sustainability,
✨ a creative engineering experience,
✨ and a fun way to explore circular economy in everyday life.

Through the workshops, children are discovering how technical thinking, teamwork, and creativity can give new life to unused materials. Step by step, they are learning that sustainability is not just a concept in a classroom, but something tangible they can build with their own hands.

And soon… the real reward:
Pedal-powered smoothies made by the children themselves! πŸ“βš‘

Beyond the smoothies, the project encourages discussions around:
🌍 Reducing waste
πŸ”„ Reusing materials
πŸ’‘ Energy and innovation
πŸ’š Healthy and active lifestyles

Seeing the children’s curiosity and enthusiasm reminds us why projects like this matter: small engineering ideas can plant the seeds for lifelong environmental awareness.

A huge thank you to everyone involved in making this initiative possible. More updates coming soon!

πŸŒžπŸ‘¨β€πŸ”¬ DIY Solar Cooker – Back in the Sun – Field Testing, Teamwork & Good Food

Last Sunday, we came together once again to see our solar cooker in action, reflect on what we’ve learned so far, and brainstorm the next steps in our ongoing research project. It was a great mix of hands-on testing, technical discussions – and shared moments.

Despite the sometimes unpredictable August weather in Luxembourg (we got lucky with the sun β˜€οΈπŸ˜…), we managed to cook a meal, enjoy the results, and exchange ideas on how to optimize performance, tracking mechanisms, and heat transfer.

🍽️ Key takeaway?

Engineering and sustainability go hand-in-hand – but it’s the human element that makes these projects truly meaningful. Sitting together, sharing a solar-cooked dish, and dreaming up improvements is what drives us forward.

πŸ”¬ What’s next?

> Testing alternative absorber Materials
> Improving reflector precision
> Collecting more performance data under varying conditions

Huge thanks to everyone who joined and contributed their insights & energy – especially Michel Guenther for pushing things forward!

πŸŒžπŸ”§ DIY Solar Cooker – Cooking with the Power of the Sun

We decided to build a solar cooker as a fun and educational science project. A solar cooker uses nothing but sunlight to prepare food – no fossil fuels, no wood. πŸŒ±β™»οΈ A small step for us, a meaningful contribution to a more sustainable future.

🎯 Goal:
To create a simple, low-cost solar cooker using common materials, test the concept, and gain hands-on experience with solar cooking.

πŸ› οΈ Our Approach:
πŸ“‘ Reused a broken satellite dish as the reflector
πŸͺž Cut small mirror squares and glued them onto the dish
πŸ›ž Used an old truck brake disc + welded steel frame for a stable base
βš™οΈ Implemented a zenith angle control mechanism for solar tracking

πŸ“Š Key Data:
πŸ”² Reflective surface: 0.79β€―mΒ²
πŸ” Concentration factor: ~130
🌑️ Test in March (Luxembourg): 170β€―Β°C reached
β˜€οΈ Test in July: 42β€―% efficiency achieved

πŸ’¬ Conclusion:
A rewarding hands-on project that combines engineering, sustainability, and reuse. A great example of how simple ideas can drive real impact.

Big thanks to our member Michel Guenther !!!

QUARTERLY MEETING EWB LUX

On June 4th, 2025, we gathered for our quarterly meeting at the university β€” a great opportunity to connect, share ideas, and reflect on recent progress.

One of the highlights was the presentation of our recently completed project in Kenya – we’re proud to have successfully delivered a water access solution for St. Joseph’s Girls Secondary School, a boarding school in rural Kenya. πŸŒπŸ’§

We also shared updates on ongoing initiatives and projects, including:
– Renewable Energy in Zambia ⚑
– Circular Economy efforts in Cameroon ♻️
– And a short report on our internal plastic recycling workshop.

It was fantastic to see both new and familiar faces β€” thank you to everyone who joined and contributed to the inspiring conversations.
