The power of the sun, 4 trillion terawatts of pure, clean energy baby! That’s been the dream ever since the secret of the sun’s power was first gleaned by nuclear physicists almost a century ago. Fusion has been a long time coming, but we may finally be getting close:
BBC— These are embryonic stages to what is perhaps humankind’s most ambitious scientific and engineering project: to replicate the Sun here on Earth.When construction is complete, the pit will host a 73-metre-high machine (240 feet) that will attempt to create boundless energy by smashing hydrogen nuclei together, in much the same way as stars like our Sun do. Physicists have dreamed of being able to produce cheap, safe and plentiful energy through atomic fusion since the 1950s. Around the world, researchers continue to experiment with creating fusion energy using various methods. But as people within the field have said the dream has always been “30 years away” from realisation.
The need for a new energy source has never been more pressing. Global energy demand is expected to double by 2050, while the share coming from fossil fuels – currently 85% – needs to drop dramatically if we are to reduce carbon emissions and limit global warming.
