Fusion reactors will one day be the ultimate in “free energy”, but judging by the latest news of holy grail moments, it won’t be soon. The bonanza of energy that everyone wants was never going to come by catching photons from the sun with a million square kilometer PV net, but from recreating the source of those photons here on Earth. It’s the energy released if we can smack two atoms together and make them fuse which requires extreme temperatures and pressures (a bit like the sun) and do it efficiently, reliably, and millions of times a day.
In the latest nuclear news round, the mini sun experiment at the Lawrence Livermore National Laboratory California gave back slightly more energy than was directly put in, which seems very exciting, but systemic total costs and energy used to “make this moment” happen are in a Supernova category all by themselves.
UPDATE: Just after publishing this blog post, news came out of a newer experiment just ten days ago:
The US’s National Ignition Facility (NIF) has announced it successfully used a 192-beam laser to turn a tiny amount of hydrogen into enough energy to […]
