Solar Butterfly takes off

Now, finally, we can tell you about it: For quite some time now, pioneer and initiator Louis Palmer has been tinkering and working with us at Hirschengraben Coworking. Mutual inspiration and a friendly and personal exchange characterize the collaboration. We appreciate that we can also contribute to the success of this story through our community and with our space - even if the «Butterfly» will soon take off.

Starting next year, the solar energy vehicle will make noise for climate protection projects. And you can apply to be a crew member!

The goal

«The solution to combat climate change is already there - it's solar energy,» says initiator Louis Palmer. With the Solar Butterfly, he wants to visit climate protection projects in Switzerland, Europe and around the world, present them and thus help them get the attention they need.

The initiator

For decades, the 50-year-old Swiss environmental activist has been committed to a sustainable lifestyle with a focus on renewable energies and emission-free electric mobility. In 2007 and 2008, he was the first person to drive around the world in a solar-powered car for 18 months - and there is even a documentary film about it.

The butterfly

The project name is to be understood very literally: This time, the solar vehicle is really a large butterfly complete with fold-out solar wings (designed to attract sunlight and stares at the same time) in which four crew members can live sustainably. The construction is in full swing and was financed with the help of sponsoring and partnerships. Now it's about financing the journey, for which there will also be a crowdfunding later on.

In these pictures you can see a few design ideas for the Solar Butterfly. The finished pendant will not look exactly like this - the thing must ultimately be functional and eye-catching.

The Tour

This journey will take in the whole of Switzerland from May 2022 and then all the continents. The final destination is Paris at the end of 2025 - just in time for the tenth anniversary of the climate agreement. In Switzerland, the Solar Butterfly aims to draw attention to a solar-powered tractor, state-of-the-art e-bikes and a crane that stores electricity, among other things.
