I didn't watch the video (probably just click bait to monetize your eyeballs, but no primary battery will last a lifetime unless it's a joke (a battery that will last the battery's lifetime).Can someone tell me if this circuit is real?
No, it won't run forever if that's what you're asking. But it will last much longer than a standard 1.5V battery. That said, you could just use rechargeable batteries for that matter. From my experience those seem to last a pretty long while before a fresh set is needed.

Thank u everyoneIt's not going to hang nicely on the wall either.
Why a transistor is used hereNo, it won't run forever if that's what you're asking. But it will last much longer than a standard 1.5V battery.

Did not understandThe last train is nearly due,
The underground is closing soon,
And in the dark deserted station,
Restless in anticipation,
A man waits in the shadows.
It drops the voltage from 4V to 1.5V (roughly).Why a transistor is used here

My sentiments exactly.
Many videos on You Tube are from India or Sri Lanka (formerly called Ceylon) where this same guy gets paid by You Tube for each useless video he posts there.You guys are....BRUTAL. Poor video maker...sniff....sob.
Lotsa people used to get paid to write useless books. Maybe we've come full circle. Making a video might be easier than writing a book.Many videos on You Tube are from India or Sri Lanka (formerly called Ceylon) where this same guy gets paid by You Tube for each useless video he posts there.
