Discussion Overview

The discussion revolves around identifying the most powerful machine ever constructed, focusing on energy production and power output. Participants explore various candidates, including rockets, nuclear reactors, particle accelerators, and thermonuclear bombs, while debating definitions of power and energy.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants suggest the Saturn V rocket as a contender for the most powerful machine, citing its power output during launch.
  • Others propose that existing particle accelerators might surpass the Saturn V in terms of energy produced, although they note that much of the energy is stored in magnetic fields rather than in the particle beams.
  • A participant mentions that nuclear reactors produce significant power but may not match the instantaneous power of a thermonuclear bomb.
  • There is a discussion about the difference between energy and power, with some participants clarifying that the Saturn V's power output is substantial but only sustained for a short duration.
  • One participant points out that nuclear bombs release enormous amounts of energy very quickly, potentially making them the most powerful machines in terms of instantaneous power output.
  • Another participant introduces the kinetic energy of the Earth in its orbit as a reference point for large energy quantities, questioning how it compares to human-made machines.
  • Some participants express surprise at the energy figures discussed, indicating a lack of awareness regarding the scale of these machines' outputs.

Areas of Agreement / Disagreement

Participants do not reach a consensus on which machine is the most powerful, with multiple competing views and definitions of power and energy remaining in the discussion.

Contextual Notes

The discussion highlights the need for clear definitions of "power" and "energy," as well as the context in which these machines operate, which may affect comparisons. There are also unresolved questions regarding the exact energy outputs and durations of various machines.

Does anyone know what the most powerful machine ever constructed might be, say in terms of energy produced?

I've heard it is the Saturn V rocket, but I'm willing to bet one of the existing particle accelerators could surpass that.

Anyone?

Nuclear reactor?
 
You need to define properly the "power" you are after. Particle accelerators run on electricity, and do not reach such high power consumption as you might imagine, because in the end the problem is not so much to burn as much power as possible, but to impart the energy in the particles accelerated. Most of the energy at the LHC for instance will be stored in the magnetic fields, not in the beams of particles, and is of the order of several GJ. I think you are right when saying this is more than the energy developed by Saturn V, although this is counter intuitive to me. I did some rough estimation, because the exact dynamics would require more data than I found. In any case, this must be way less than the several MT developed by some nuclear weapons, which are of the order of millions of GJ. That would be the most powerful machines ever constructed, although the energy is merely released and not controlled, which could be considered pretty useless. :frown:
 
You said energy - did you mean power? The Saturn V (stage 1) produced 141,000 MW of power - but only for about 2.5 minutes. Or 5,900 MWh. A typical nuclear reactor puts out 1,000 MW. So a Saturn V first stage put out as much energy in 2.5 minutes as a nuclear plant does in 6 hours.

Wow, I didnt realize it was that much.

That is indeed the whole question. When I mentionned LHC magnets, that was in terms of stored energy, and because particle accelerators were mentionned by the OP. I thought nuclear bombs were relevant, because (as far as I know) they output the largest power. But indeed, a nuclear plant running for several years can outgrow in energy pretty much anything else.

So, a good reference in terms of huge amounts of energy would be the total kinetic energy of the Earth in rotation around the Sun. I did not check, wikipedia gives 2.6\times 10^{29} J. How many hours of a typical nuclear plant ? :biggrin: :rolleyes:
 
Wow a gigaJoule!
 
If we go for power, and human-made, then I think that a thermonuclear bomb wins the contest. A megaton is 4.184 petajoules (see http://en.wikipedia.org/wiki/Kiloton ), your typical thermonuclear weapon is a 10-20 megaton (although the Soviets made a 100 megaton banger), so we are talking about 100 petajoules, or ~ 10^17 joule. The energy-delivering explosion itself takes about 10 microseconds (this is an educated guess of mine, given that that's about the time it takes for the shock wave to reach the thermonuclear part and hence blow it apart).

So we are talking here of a 10^22 Watt device - which, granted, doesn't work a long time.

Allegedly, and it only took a 5 days.
