  • ANNOUNCER: THIS is Capitol TV.

  • [Music]

  • [Beat, music]

  • DEREK: Greetings citizens. Welcome to the Coriolanus 9 solar thermal power plant in

  • the heart of District 5.

  • This facility generates over 7% of our proud

  • Capitol’s energy needs.

  • But did you know that you can generate electricity

  • from mere drops of water?

  • I’m going to show you an experiment

  • that does just that.

  • As we turn on the water, it falls through these rings, and onto this mesh below.

  • But look here. After a moment...

  • [Electrical buzz]

  • ...there it is.

  • It generates a spark of roughly 20,000 volts

  • of electricity. [Electrical buzz]

  • And there is no power source here,

  • no turbine as in traditional hydro generation.

  • In fact, there are no moving parts at all.

  • We are creating electricity using only the

  • intrinsic properties of falling water.

  • So how does it work? Well, water contains

  • charged particles called ions.

  • It has equal numbers of positive and negative

  • ions, so overall it’s neutral.

  • However, as the water falls, there will sometimes

  • be a slight charge imbalance,

  • with a little bit more negative charge over

  • here and a bit more positive charge there.

  • Under ordinary circumstances, these variations

  • would even out over time, but not in this case.

  • Here is the ingenious part - the mesh on the

  • left is connected to the ring on the right.

  • So if this mesh becomes negatively charged,

  • then so does this ring.

  • And now that ring will attract the positively

  • charged ions in the water,

  • So the mesh on the right

  • will now be more positively charged

  • meaning so is this ring

  • So what we have is a clear separation of charge.

  • There’s a positively charged stream on the

  • right, and a negatively charged stream on the left.

  • And the more the charge builds up on the meshes,

  • the faster that charge increases.

  • And finally when we have reached our designed

  • operating voltage of 20,000 volts,

  • electrons jump from the negative rings to

  • the positive ones through this spark gap... [Electrical buzz]

  • DEREK: ...ionizing the air as they do so.

  • We have created an electric generator with

  • little more than a stream of water droplets.

  • No field of mirrors or enormous coal-burning

  • plant is required

  • In fact, with access to the right

  • materials, you could even build this apparatus at home.

  • Thank you for your attention.

  • We citizens of District 5 expand our knowledge

  • to better serve our great nation.

  • Love your labor, take pride in your task.

  • Our future is in your hands.

  • And, don’t forget to register for updates

  • from Capitol TVit’s mandatory.
