File this in, color me worried about "what could go wrong here".. via RT: An alliance of 35 countries has finished laying the groundwork for one of humanity's most ambitious experiments – to harness nearly unlimited amounts of energy by creating 'small stars' on Earth. The extreme heat and gravity inside the core of the Sun and other stars make hydrogen atoms collide and fuse into heavier helium atoms, releasing tremendous amounts of energy in the process. Scientists want to replicate a similar mechanism on Earth in order to generate energy that will be efficient, renewable and carbon emission-free, so it will not cause climate change. Moreover, controlled fusion reactions are projected to create four million times more energy than the burning of coal, oil or gas, and four times as much as nuclear power plants. However, the design of a large-scale fusion device requires immense resources, so a decade ago 35 countries combined their efforts to build the International Thermonuclear
