Nuclear fusion breakthrough: what do new results mean for the future of ā€˜infiniteā€™ energy?

The Lawrence Livermore National Laboratory has announced a major breakthrough in nuclear fusion, using powerful lasers to produce 1.3 megajoules of energy ā€“ about 3% of the energy contained in 1kg of crude oil.
