The Future of Fusion Energy, by Jason Parisi and Justin Ball

Since I am interested in a book that acquaints a layman like me on nuclear fusion, this is an excellent choice.

The book starts with an exposition of the present and future energy needs of humanity, contemplating the possible options: fossil fuels, renewables, and nuclear fission and fusion. 

Then it exposes the physical principles and each of the technologies -both of which are many- involved in obtaining fusion energy. It is certainly a very, very complex (and expensive) issue. It should be noted that nuclear fusion -the energy from the sun - has been achieved artificially for more than half a century, with the fusion bombs. "Simply" it is a question of being able to lock up this force and use it for peaceful purposes.

So I realize that it is a very difficult subject to explain for a curious reader without specialized knowledge like me, but I think the book more than succeeds in doing so, with very didactic and understandable explanations -considering the complexity of the matter- and with the help of ingenious metaphors and also also some really funny comments.

Finally, the book also deals with the issue of fusion reactors as the energy that in the future can greatly facilitate space travel throughout the solar system.

Without a doubt the fusion energy itself is an achievable goal, it is only a matter of investment in research, time and also of political will, for example if the great international project ITER can be achieved (planned for 2025). We will have to be patient then, because without a doubt this must be the energy that meets the needs of humanity in the future, if there is a future...
