There are numerous obstacles. Once the initial idea of Eureka was formulated, we were able to foresee the difficulties to be faced. But we know that each time we come together — for example to address high-energy physics, research into nuclear fusion, the development of an integrated space programme or the construction of crucial scientific equipment — our successes encourage us in the idea that we can work together in R&D areas close to industrial markets, despite the problems arising from the normal and legitimate competition between firms.
