The greenTEG thermoelectric generators generate electricity from heat – without detour via steam boilers and turbines. The principle has long been known. But only a production process developed by Etienne Schwyter in the four-headed greenTEG founder team makes it economically interesting. The generators from Zurich are not only significantly cheaper than before. In addition, they are also thinner and more flexible and can be produced more expensively.
