वो बल्ब जो 122 सालों से जल रहा है

कैलिफोर्निया के लिवरमोर शहर का एक बल्ब 122 सालों से जल रहा है.

[{"selector":"#anim-aaf75ba4-9e52-4ea2-adf3-238346ca509b","keyframes":{"opacity":[0,1]},"delay":1000,"duration":2000,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-27991df1-34a6-4556-ae1a-e336530e2338","keyframes":{"opacity":[0,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-69ef47e4-8ce6-404f-827b-5548930edf65","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

ये शहर के फायरब्रिगेड विभाग के गैराज में लगा है.

[{"selector":"#anim-50848b75-7e76-443c-a173-4ce6caae8c24","keyframes":{"opacity":[0,1]},"delay":1000,"duration":2000,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-8a1028ba-2774-44d8-89b9-1573da6b6f6d","keyframes":{"opacity":[0,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-c4075637-7db4-4d0a-af63-483ec69f9746","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

इसका फिलामेंट कैसे अब तक सुरक्षित है, ये भी एक हैरानी ही है.

[{"selector":"#anim-29f60ae2-7f58-48ff-9175-aac8a4a38e51","keyframes":{"opacity":[0,1]},"delay":1000,"duration":2000,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-2fc0c49f-aa95-4598-ac79-a4382cb3df76","keyframes":{"opacity":[0,1]},"delay":0,"duration":3500,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-fd6d08c7-6225-4fa2-a340-d100b769e19e","keyframes":{"transform":["translate3d(0px, -119.71414%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":3500,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

इस बल्ब का नाम है सेंटेनियल, जिसे साल 1901 में पहली बार जलाया गया था.

[{"selector":"#anim-3fc96591-02ba-4cab-b42f-e3780012f6ec","keyframes":[{"offset":0,"transform":"translate3d(0, -155.27284%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.29,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.45,"transform":"translate3d(0, -43.662722608%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.61,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.71,"transform":"translate3d(0, -14.844083504%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.8,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.85,"transform":"translate3d(0, -5.574294956%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":0.92,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"},{"offset":0.96,"transform":"translate3d(0, -2.422256304%, 0)","easing":"cubic-bezier(.5, 0, 1, 1)"},{"offset":1,"transform":"translate3d(0, 0%, 0)","easing":"cubic-bezier(0, 0, .5, 1)"}],"delay":0,"duration":3500,"fill":"both"}]

1901 में यह बल्ब 60 वाट का था. फिर इसका आउटपुट कम होता गया.

[{"selector":"#anim-92c40c0b-3aa5-4f16-a1b4-b68a66e89c15","keyframes":{"opacity":[0,1]},"delay":1000,"duration":2000,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-065ed185-e329-499a-b8c1-2a7efdfd8014","keyframes":{"opacity":[0,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-653a23a3-a8d0-45ed-9fdd-4d16df8723a6","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]

अब इस बल्ब की रोशनी 4 वाट के बराबर रह गई है.

[{"selector":"#anim-336ee0d2-a69c-4940-8f39-d435f3080b57","keyframes":{"opacity":[0,1]},"delay":1000,"duration":2000,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-4b7e7221-9f7e-4857-91b9-63998ef037a0","keyframes":{"opacity":[0,1]},"delay":0,"duration":3500,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-739e2095-c5db-45a5-9e39-8fa0adaa037a","keyframes":{"transform":["translate3d(107.20222%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":3500,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

इसे ओहियो की शेल्बी इल्कट्रॉनिक नाम की कंपनी ने बनाया था.

[{"selector":"#anim-ff2a410b-8b30-4945-a9d4-616f36cfc324","keyframes":{"opacity":[0,1]},"delay":1000,"duration":2000,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-fe789923-f867-42f9-9987-01c7d345c481","keyframes":{"opacity":[0,1]},"delay":0,"duration":3500,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-e47295b2-ce1c-4878-a94e-8bb3a0feabbf","keyframes":{"transform":["translate3d(105.08021%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":3500,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

इसे 02 बार आधिकारिक तौर पर इंटरवल दिए गए.

[{"selector":"#anim-d3630d82-8d7b-4b71-b693-02ccc72dcb45","keyframes":{"opacity":[0,1]},"delay":1000,"duration":2000,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}]

कुछ लोगों का मानना है कि इसका खास डिजाइन ही इसे अब तक बरकरार रखे है.

[{"selector":"#anim-022ae01f-5d64-4773-8be8-f903183e6185","keyframes":{"opacity":[0,1]},"delay":1000,"duration":2000,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-5982480e-8b8d-487b-9d7d-a58cc6cd099c","keyframes":{"opacity":[0,1]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-1a5a4836-71dd-4271-b505-6ef9357a8bad","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}]
