As much as Wieland likes Bern, in the late afternoon he always looks forward to his return journey on the “Bern Green Belt” back to the organic farm in Thörishaus. The family man and former engineer lives here simply and close to nature. He prepares his pears, beans, or even polenta using muscle power or solar-powered machines. Wieland likes to tinker and is constantly working on new projects. For example, he invented the productive fitness centre. Those who exercise here grind maize or press rapeseed oil at the same time. After the workout on the specially made machines, the goods can be taken home. It could hardly be any more sustainable!
