I don't understand the problem in making sustainable fusion happen

Explain it to me a lay person.
The issue is they don't have enough energy to:
A) Create and sustain a reaction long enough
B) Also power the containment of the whole reaction at the same time
C) Generate this whole reaction not at some massive net loss of energy.

Maybe I'm stupid or over simplifying this. Why not hook one of these big fancy Chinese reactors directly to say a gigantic hydroelectric dam (or other renewable resources) that more or less generates infinite huge amounts of energy and use those to power reactors?

Pretty stoned.

Regarding a "hydro" power "battery"
It's feasible to think about a torridal container in which a superfluid slushes around friction-less. If the walls of the container are strong enough the momentum, or speed of the superfluid could be increased by arbitrary amounts.

Where it breaks down is of course we know of no superfluid that remains stable without constant cooling and no materials to build the container out of.
Furthermore every conceivable method of extracting or putting in energy from/into the fluid will have losses.
But I suppose if we can use superconductors all over the process those losses would just amount to imperfections and quantum fluctuations.

The question in OP while interesting doesn't make sense to me without some creative interpretations.
Also congrats OP of being able to continue your stoned train of thought at a later date, I'm jealous.

Does a machine that uses 500W emit more em radiation shit than a device that only uses 250W? also where is the source of the radiation, is it through the power outlet where its plugged in, and if it is, the further away from the power outlet one is the less exposure to radiation one will experience?

Best regards, Pete from smallville

>>79534 I do partially agree with >>79535... but we also know that school sucks at conveying information. Internet kooks don't exactly help in this matter either.

Now, EM radiation is basically anything from longwave radio, microwaves, through visible light to gamma radiation....
But still it's hard to say whether a 500W device will generate more EM radiation than a 250W device. Wattage itself is a measure of how much *energy* is released. Energy in itself can be released in other forms than EM radiation, like kinetic energy.

In some cases it's true, A stronger lightbulb, radio transmitter or microwave oven will release more EM radiation than a weaker one - on the other hand, the very purpose of those are to generate EM radiation (microvave radiation, radio signals and visible light respectively).

Compare, however, two very different devices, and you'll see it's not entirely true.
A car engine, for example will likely emit less EM radiation than a microwave, as its primary function is to generate kinetic energy. Car engine power can be measured in the range of kilowatts (thousands of watts) compared to the microwave oven, which is usually 1 kW at most.

Now, even a relatively weak car engine outputs around 100kW - a hundred times more than the microwave oven, probably 80% of that goes to moving the car, while 20% is released as heat (which can be released either as EM radiation or be conducted though various materials eg. air, water or metal). Comparatively less energy goes to generating EM radiation in the car engine than in the microwave oven, as again ,the purpose of the latter is to actually generate EM radiation of a certain frequency in order to excite the water molecules in the food.

>em radiation shit
Don't fall into that ballpark... our universe is dominated by EM radiation - you'll never be free from it :)

hello there /chem/ I've been reading uncle festern books and I would like to ask:

is this serious chemistry to be applied? what do you think of his methods? good, bad or dangerous?

thanks, SLAYER to all chems (seeing Bombastus still here is great as fuck, I've been outta here for long time)

https://en.wikipedia.org/wiki/Protein_primary_structure
>Protein primary structure is the linear sequence of amino acids in a peptide or protein. By convention, the primary structure of a protein is reported starting from the amino-terminal end to the carboxyl-terminal end. Protein biosynthesis is most commonly performed by ribosomes in cells. Peptides can also be synthesized in the laboratory. Protein primary structures can be directly sequenced, or inferred from DNA sequences.

I started a thread on /spooky/ asking for any evidence of the paranormal or supernatural.

Instead all I got was a bunch of personal attack and people babbling nonsense and presenting it as truth. Then when shown they are incorrect with verifiable data rather than pseudoscience they resort to personal attacks again. They and pretty much all other magical thinkers take any sort of challenge to their beliefs as a personal attack.

I was at a party a few months back and some girl was talking about how she went to some yoga guy who does "laying on of hands". Which involves doing yoga while a dude puts his hands on your body and makes weird noises. Supposedly doing this achieves any number of effects from healing wounds, curing depression and other supposed boons.
not arguing the therapeutic effects of yoga just the laying on of hands part
I tried to understand what she was explaining to me by asking questions. Like asking her what was actually happening because it made 0 sense to me. Instead she started insulting me for being closed minded and shit.

Also in real life I live in the US south. Where people who think the world is 6000 years old is the norm.

Needless to say I deal with people who use magical thinking on a regular basis.
They are 100% willing to reap the benefits of science and the technology that comes with it until it conflicts with some myth or story about ghosts or some shit some one told them. Then all reason and logic go out the window.

Why do so many people especially in the us reject verifiable facts over what feels good? I went to the same public schools as them, I was also raised in a religious household (jewish, although I'm no longer religious). The only difference is that I chose the rational answer.

Idk, maybe I'm just a giant nerd who paid too much attention in school. It's frustrating living among all these science denialists.

Also all of the above isn't a rant about religion. You can be religious and a realist, I have several christian friends who understand their religion and all others aren't meant to be taken literally. I actually respect people who can strike the balance between their religion and what the real world shows them.
