  • 05:21: And 3) a source of free energy.
  • 07:53: And finally, life condition number 3: do we have a source of free energy?
  • 07:58: By free energy, I don’t mean energy that you don’t have to pay for.
  • 09:02: OK, so inside a star there’s definitely free energy.

2019-03-06: The Impossibility of Perpetual Motion Machines

  • 08:41: One popular source of free energy is the zero-point energy of the quantum vacuum, and it’s the most fun to debunk.
  • 09:37: ... torus vibrations sound fancy, but are typically less good at generating free energy than they are at directing you to their donate button or selling you a ...

2018-07-25: Reversing Entropy with Maxwell's Demon

  • 00:38: Ultimately, entropy is a measure of the availability of free energy, of energy that isn't hopelessly mixed into thermal equilibrium.
  • 04:06: ... is from thermal equilibrium, and it also defines the availability of free energy, energy that can be extracted as the system moves back to ...

2018-05-23: Why Quantum Information is Never Destroyed

  • 11:29: In a related question, AFastidiousCuber asks why free energy and perpetual motion machines are impossible?
  • 11:49: Pepsi could extract some free energy if you could build a device that spans several million light years or, I don't know, install some solar panels.

2018-04-11: The Physics of Life (ft. It's Okay to be Smart & PBS Eons!)

  • 04:42: The type of order that life feeds on can be thought of as free energy.
  • 04:46: By free energy, I mean the special out-of-equilibrium energy sources like a cup of coffee or the sun.

2018-01-31: Kronos: Devourer Of Worlds

  • 08:34: ... doesn't change the chemistry of the atmosphere, and B, we get unlimited free energy. ...

2017-11-22: Suicide Space Robots

  • 14:57: Those false powers sometimes sound pretty cool because they imply things like infinite free energy or fast space travel.

2017-11-08: Zero-Point Energy Demystified

  • 02:10: Why can't we pull infinite free energy out of nothing?
