The idea for the Micro Wind Turbine came about in March this year as a result of Ferber finding that his smartphone would routinely lose charge on long treks. He turned to a number of mountaineers, climbers, film-makers and expedition leaders for advice and found that solar chargers were the overwhelmingly popular solution, but that their sunlight dependency was considered a serious shortcoming.

His suggestion of a wind turbine is said to have been well received, but weight, pack-size and ease-of-use were flagged up as key factors that would affect uptake. Portable wind turbine device chargers, like the Trinity, do already exist, but Ferber says there are none of a similar scale that are commercially available, as well as adequately simple, portable and effective. As such, he went about creating one that would meet all these requirements as the graduation project for his Master's course of product design at the École cantonale d'art Lausanne (ECAL).
