Nuclear fusion is regarded as the energy of the future. It does not emit CO2, it is safe and it provides a lot of energy that can easily supply large cities with electricity. Nuclear fusion is very interesting in theory, but not yet in practice. Scientists have already succeeded in making nuclear fusion happen, but to make it profitable a lot of research still needs to take place in the coming years. TU/e researcher Michele Marin takes his part with his research on nuclear fusion plasma.
