Menneskeskabt Fusion

Der er bygget flere forsøgsreaktorer, men selv de nyeste kan kun lige producere en mægde energi, der svarer til det, der tilføres for at holde prosessen i gang. Der er et omfattende international prohjekt i gang med henblik på at bygge en reaktor, der kan producere et overskud af energi. Reaktoren, der kaldes ITER, vil dog ikke kunne levere nok energi til at anlægget kan bruges kommmercielt.

Dog har vi muligheden for at lave en fusionsproces, nemlig brintbomber som til forskel fra almindelige atombomber ikke benytter sig af fissionsteknologi. Desværre skal der en atombombe til at tænde en brintbombe, og dette sker ved flere millioner grader, og det har vi endnu ikke fundet noget der kan holde til.

Now it remains to be seen how the physics community will respond to these results..."
