TOKAMAK ENERGY

Aren't Stellerators just Tokamaks with a twist?

>"can explode with their fast neutrons"
hrrm.
so he became a terrorist because nobody ever educated the guy on neutron absorption?

He spent ten years becoming a terrorist while never attempting to understand what he was up against. I don't think it's possible to educate such people.

heh

"Breakeven" is an arbitrary, misnamed, and somewhat ill-defined milestone in fusion. They like to talk about the energy released by fusion reactions being equal to the energy being used to power the machine, but that's not nearly enough to actually break even on energy spent and energy extracted, since there will be large conversion losses if they try to convert the fusion energy to electricity. There are also many different ways to measure the energy spent, and they like to cheat by counting it after many lossy conversion steps from the original source, for instance from grid electricity to energetic particle beams.

More relevant milestones:
1) produce more electricity while running than it takes to run it,
2) sustain continuous net electricity production for at least a week,
3) "ignite", so energy is only spent containing the reaction, not sustaining it, and
4) put out more electricity during the device's lifetime than the full total of useful energy used to build and run the device.

>breakeven in 5-10 years
oh look the same old lie

They have never, and will never, attain "ignition". It makes me sad to think how this meme keeps getting passed down to each generation with the same lie.

pretty funny that the 1st energy generator that's verified to output more than 100% energy that's input (up to 170% output) is designed to be a water heater.

If it's so certain, why are they trying?

You couldn't find any shittier source than a fragment of a documentary with the names clipped out and no links or other details in the description?

Honestly, what this sounds like is a heat pump: a reverse air-conditioner. It's not actually hard to get more joules of heat out one end than the electricity you put in, as long as there's a cold part on it somewhere sucking heat from the other end.

Other explanations could be: incompetent heat output measurement, incompetent electrical input measurement, and metal parts being consumed in exothermic chemical reactions.

I don't agree that it will never work, but there doesn't need to be a realistic chance of success for workers to want to take paychecks, and for funders to not understand it well enough to refuse to sign them.

Also, for the government efforts, there are bureaucratic empires to be built around any big, expensive project, regardless of whether it serves any purpose.

lol no, the goyim still don't know.

>cavitation devices
>overunity
lolno

Ah, here's the source documentary:
youtu.be/DjGSXKSLpfY?t=560
The real meat's at 9 minutes 20 seconds in, when a scientist who comes in for a look says their measurements are shit, but at 7:24 you also learn that they're actually only claiming a gain of 8-15% in sustained operation, not the 30% or 70% they throw around.

8-15% is easily explained by measurement error. And places claiming to have such a small reduction in their heating bills can be explained by many other changes. Just being more watchful and alert of energy waste will normally result in reductions.

>Mass of output is less than mass of input => Mass becomes energy => mind=blown
>Besides blowing each other up, most useful application is to boil water

The water isn't going to heat itself.

You can do direct energy conversion and avoid boiling water.

2020 is less than three years away, user.

>What precisely causes the claimed excess heat? Griggs himself rejects the popular idea that his pump has something to do with so-called 'cold fusion'.
>'We have kind of been lumped into the cold fusion field', he says wryly, 'because we have experienced excess energy out of the pump. As far as cold fusion goes, we don't believe that we're accomplishing any type of nuclear reaction within our system.
>'During one of our investigations,' he says, 'over a 20 minute period, 4.80 Kilowatt Hours of electricity was input, and 19,050 BTUs of heat evolved, which equals 5.58 Kilowatt Hours, or 117 per cent of input. The actual input to output ratio was even better than this, when you take into account the inefficiencies of the electric motor.'
>importantly, the excess energy does not actually appear at the output steam pipe for a constant input of energy. What happens is this; the pump is started and after five or ten minutes reaches a steady state where it is converting water at room temperature to steam. Once this steady state is reached, the pump goes into an over-unity mode where the output temperature is maintained, but the amount of energy needed at the input to maintain it, drops by 30 per cent.
>Griggs has been working with a number of physicists and engineers to try to get to the bottom of just how his device works. As well as Rothwell's consulting engineering firm in Atlanta he has worked with Professor Keizios, dean emeritus of the Department of Mechanical Engineering at Georgia Institute of Technology and past president of the American Society of Mechanical Engineers. Keizos supervised the design of the instrumentation that measures the energy input and output of the Griggs Gadget.
>In a second test, during which the over-unity effect was measured, the adjusted co-efficient of power was a remarkable 168 per cent -- the machine produced 1.68 times the energy that was input. A third test did nearly as well with a Co-efficient of power of 157 per cent.

Even if the thing isn't achieving over-unity (and nobody really thinks the thing is doing fusion), it's still an interesting phenomenon.

He3 + He3 fusion.

Which is really hot but low output. Plus the fuel is scarce on earth.

It uses super-cavitation.

It's the same principal that allows a tiny shrimp to increase the temperature of water to more than the temperature of the sun (4,700 °C) in a mere fraction of a second. Only instead of a single click of a shrimp claw, it's doing this an innumerable amount of times over a sustained period.

That might be true. That doesn't explain the anomalies in energy input to energy output. Well, it might, but it should be explainable through math.

>this creature can create fiery shockwaves that can instakill other fish at will

It's generally the least complex and most efficient way.

>pistol shrimp
Bow that's a badass name

this is why mechanical engineering is such good job security.

I'm probably what you guys call a brailet (in intended to click on /p/ and missed, but then got intrigued by this and the nanomachines thread..), but is there some sort of energy release during change of state of matter?

Super-cavitation combined with friction sound pretty plausible as well though..

FUCK FUSION
THORIUM SALT REACTORS WILL RISE AGAIN!!

found old NASA article from the 60's. I don't think they were trying to generate hot water, but were studying cavitation in genera. Brainlet here so I can't make much sense of it but it clearly shows the metal of the machine being damaged by caviation which is interesting.

How does cavitation relate to the casimir effect and vacuum energy? From what I understand cavitation is basically making a pure vacuum underwater that lasts a fraction of a second. Wouldn't that create virtual particles and do some science stuff? Sorry for the vernacular.

>energy release during change of state of matter?

Yes. It's referred to the enthalpy of vaporization. Takes more heat to cause a state change than the heat required to just raise temperature. Even water boiling is technically cavitation. The only difference is that boiling usually refers to vaporization due to adding heat, while cavitation is usually the result of lowering pressure locally in a liquid, causing temporary vapor expansion, and then subsequent collapse. The difference is just semantics. Check out acoustically induced cavitation, it's fun!

AFAIK cavitation is a well-understood phenomenon(well, about as well understood as any complex fluid behavior, the models are never easy or perfect), because it's very prevalent in a lot of industrial scale equipment. Boat screws, pumps and the like all risk suffering damage due to cavitation and are designed to avoid it.

I don't think it has anything to do with the casimir effect or vacuum energy. What is most fascinating about cavitation is the very small, localized amount of extreme heat in the center of the collapsing cavitation bubble, before the damaging shockwave.

I don't think cavitation has anything to do with the casimir effect and vacuum energy.

maybe if you stupid fucks placed your trust in Randell L. Mills hydrinos theory we could all have the power of tens of thousands of sun equivalents that could be directly converted into electrical power

tri-alpha works on direct energy conversion.

How does reading this not trigger your gag reflex.

gotta brew tea SOMEHOW dude

How the fuck else are you going to cook your damn spaghetti?

>muh infinite energy source
fuck off

It's almost like water is a really effective means of transferring energy or something.

Except it was actually operational for a long time and it was shit.

delet this post right now

then how come i have to drink coffee for energy instead of pure water?
