Welcome to GEM: The Green Energy Mill. A foldable tower designed to provide solar and wind energy at festivals and events. After two years of building, testing, and refining, GEM was supposed to start its European festival tour this summer. Due to COVID-19 we had to change the original plan. Instead of showing the GEM Tower at the festivals itself, we now talk to the festival organisers in a new video series. We proudly present to you: Digital GEM Tour. A new video will be released every Friday!

After weeks of GEM being in lockdown, it’s finally time to bring out the tower and to run tests. The GEM-Tower is now located at the Fieldlab Smartbase, a military base from the Dutch Ministry of Defence in Ede-Driesprong (NL).

The GEM-tower is a green energy solution for festivals to replace fossil fuels and will help festivals to be more sustainable.
