Thomas Edison, aka Klaas Guldie and Nikola Tesla, aka Lieuwe Dragt, visited the second Green Trust Academy of this season on 15 November 2018. As owner of a wind farm, Tesla wanted to sell the electricity to Edison. In 12 acts in which all aspects of the negotiations about a power contract were reviewed, Tesla and Edison turned the alternating current into each other. The goal was to realize a sign-ready agreement with regard to the supply of electricity from a wind farm with a production of 100GWh per year. At the end of the evening, Edison and Tesla put a signature on a financeable result and put a toast to a lighted collaboration.
