This was TBLI Conference Zurich 2019

Posted Saturday 20 July 2019 by Urs Riggenbach.

Last month I attended the TBLI Conference in Zurich. The conference brought together impact investors and companies with a commitment for real impact.

This was certainly one of the best conferences I’ve attended. Many participants shared in the impact-maximizing spirit, ready to learn about scalable impact solutions, have their own views challenged and motivated to figure out how we can use the ressources at hand to avoid climate and economic collapse. I look forward to collaborating with the many new contacts made.

TBLI stands for tripple bottom line, the concept of measuring a business not only on financial, but also on social and environmental returns. Learn more on TBLI here


Connecting Builders: Switzerland meets Togo

Posted Thursday 27 August 2015 by Urs Riggenbach.


Recently we connected the two early adopters Kurt Baumann, who built a Sol4 with his school-class in Switzerland and Boris Awume from Togo, whom we potrayed earlier. Boris currently works in Switzerland but he’s going to start building in Togo at the beginning of September. We used the opportunity to get the two early adopters together.

After some coffee we dove right in: Kurt took us to the school building where he now stores the Sol4 during the summer holidays. Kurt suspended the whole mirror-rows straight from the sealing: "That way they take up less space and we keep them out of reach from our students."

When not in use, Kurt disassembles the Sol4 and suspends the whole mirror-rows to savely store them.

We took one mirror row out into the sunlight to have a closer look at the individual pieces Boris will need to fabricate in Togo. These are notably all straight and simple metal pieces that only need cutting and welding. They also looked at the upward reflector and the custom tools we outline in our construction guides:

I really liked the fact that we built our own tools to complete the machine. These tools are quick to build and effective for the job, and I felt revived in the age-old art of toolmaking.

First Sizzle with the Sol4 in Switzerland

Posted Monday 20 July 2015 by Urs Riggenbach.

After setting up the solar concentrator in the school’s yard, the students had to calibrate the mirrors. Soon enough the vegetables, burgers and bacon were easily cooked with nothing more than sunlight. This is what Free The Sun is all about!

As indicated by the GoSol.org team it really did take us 2 hours to calibrate the mirrors but then our surprise was great once the water started boiling and the veggies and burgers started to sizzle in the pan!

It was a great success: everyone who came out of the school-building waited in line to get their share of the solar snack the students prepared for everyone.

The Next Steps

Now that the summer holidays approached the solar concentrator gets a break too, until Kurt starts the year with a new class of students. Apart from cooking and demonstrating renewable energy, schoolteacher Kurt is an artist at heart and is already thinking of using the powerful solar array for his student’s next projects.


Swiss Schoolclass is Building a Sol4

Posted Monday 13 July 2015 by Urs Riggenbach.

Kurt Baumann is a handicraft teacher in Langenthal, Switzerland. He is our first MultiPass supporter, and wants to build a solar concentrator as an educational project together with his students.

Kurt teaches his students anything from woodworking to welding to general handicraft skills. Building the Sol4 his’ class final project and the 15 to 16 year old students are truly mastering their task.

Here are some images from the constructions underway.
