    I can’t believe they let him that close to the turbine output shaft lol
  • I’m sorry they’re WHAT That is ridiculous levels of efficiency, this must be really well engineered and I have no idea why they let Hammond so close to it with a power tool
  • @Kedzke
    That small dynamo left a very noticeable skid mark on the generator.
  • @tomtommyl805
    I was in the generator room of the hoover dam once. Standing next to a 40 ton solid steel shaft rotating about as fast as this one. What i found amazing was that there was no vibration, no sound: nothing. I was awestruck.
  • @ferdtheterd3897
    25 tonnes spinning at 500 rpm is a thrillingly terrifying amount of power
  • For those interested, this type of turbine is called a Pelton Wheel, and is an example of an impulse-type turbine. Further, the scoop discussed also serves the purpose of reversing the direction of the water flow to increase the change in momentum on the water, and thus increase the momentum imparted into the turbine.

    "This massive battery holds back 200 million tons of water." "DAM!"
  • @ElectricFuture
    Not gonna lie, this content is absolutely best in class, taking notes
  • @diobrando6245
    "I'm stealing their power, hahahaha!" That laugh is nostalgic

    4:31 machinists shaking their heads watching him leave rubber residue on their perfect clean machine

    Somehow I can already hear Jezza screaming "Oi, who nicked my bike light? Haammoooonnndd!"
  • @nerdyneddy4350
    These videos are very motivating and i suggest Discovery channel releases the full video rather than these excerpts.....just saying
  • I'm Austrian and went to a technical school. We once went there and even walked through the dam itself! Pretty dam impressive.
  • @frankersh4361
    Can we just appreciate for a minute, the astounding quality, perfect backing audio, and incredible narration? This show is amazing!
  • @astrobappo9133
    me with a triple monitor setup dude in a dam with at least 10 monitors setup
  • @PluetoeInc.
    7:36 Did Anyone notice just how that hanging balcony is Perfectly shaped like the Pelton Wheel ( the turbine ) design , engineers having fun I suppose ;)
  • It's interesting to think that regardless of how small it was, he really was taking away from the overall power output by just placing that motor there.
