Scientists to build a new prototype nuclear fusion reactor

If successful, the project could be the answer to the world’s clean energy needs.

    A global partnership of scientists is building the first prototype nuclear fusion reactor in southeast France.

    At a cost of at least $24bn, the project could be the answer to the world’s clean energy needs when it is switched on - but that won't be for another 17 years.

    Engineers say the project is so complex and expensive that they fear delays could cause countries to withdraw funding.
