After Cuba, Eerik came to Europe in hopes of diffusing still further this open source technology with a solar community. He first worked to build a network of individuals and associations to diffuse the project in south of France and in Corsica. Toward this end the non-profit association Projet du Feu Solaire was created in Marseille in 2007.
In 2007 Eerik created with Eva the open source Solar Fire website with free constructions guides to encourage 'do-it-yourself' constructions everywhere in the world.
More than 20 Hélios and/or Batant/Vesta have been built in Mali, France, Belgium, Morocco, Madagascar, Kenya, and Texas, mostly for small collective uses, and many persons learned the techniques with Eerik or by themselves.
In 2009, in one of the factories of V. K. Desai (Tinytech), northern India, Eerik and Eva developed the Prometheus 100/Raviraj 100 (here) to produce solar steam for commercial or collectives uses... This prototype has been achieved on January 2011 with the SFP32, a concentrator of 32 square meters.
Eerik's vision of a decentralized solar economy is presented on Decentralized Democracy.
