  In August 2023, IT experts and scientists came together for a workshop to
discuss the possibilities of building a computer cluster fully on renewable
energies, as a test-case at Havana University in Cuba. The discussion covered
the scientific needs for a computer cluster for particle physics at the InSTEC
institute at Havana University, the possibilities to use solar energy, new
developments in computing technologies, and computer cluster operation as well
as operational needs for computing in particle physics. This computer cluster
on renewable energies at the InSTEC institute is seen as a prototype for a
large-scale computer cluster on renewable energies for scientific computing in
the Caribbean, hosted in Cuba. The project is called "Humboldt Highway", to
remember Alexander von Humboldt's achievements in bringing cultures of the
American and European continents closer together by exchange and travel. In
this spirit, we propose a project that enables and intensifies the scientific
exchange between research laboratories and universities in Europe and the
Caribbean, in particular Cuba.
