Ukuthuthukiswa kwezintambo zikagesi kudlule izigaba eziningana. Kusukela ezintanjeni ezingenalutho zasekupheleni kwekhulu le-19 ukuya{2}}kumakhebula anamandla aphansi ekuqaleni kwekhulunyaka lama-20, futhi ekugcineni ukuya{4}}kumakhebula kagesi aphezulu maphakathi nekhulu lama-20, ubuchwepheshe bekhebula lamandla buye saqhubeka nokusungula nokuthuthuka. Njengamanje, ngokuthuthuka kobuchwepheshe be-superconducting, ucwaningo kanye nokusetshenziswa kwezintambo zamandla amakhulu kuya ngokuya kusabalala.
