I've just seen this, which answered most of my questions on fusion: https://www.youtube.com/watch?v=BzK0ydOF0oU&t=19s

It shows the biggest problem for the D-T fusion is actually Beryllium. So despite all that progress and engineering wizardry there are still fundamental hurles that don't allow Tokamak D-T fusion to scale.

Thanks.

How far apart is the fusion temperature from the fusion ignition temperature and how is each one defined?

This was answered in a comment below somewhere. perhaps even by you

I always wondered how the breeding works then. Don't the free neutrons go anywhere in a Tokamak and are most likely to be captured by the surrounding atoms with the highest coloumb surface?

Thanks.

wait. So the better the isolation i.e. energy confinement the lower the ignition temperature?

And you will never get any fusion reaction below a certain temperature, because Temperature is really the Bolzman distribution of particle mv2 and particles faster than X at temperature Y just don't exist due to quantum stuff Z?

How much lower is this temperature?

Is the main motivation of using Tritium the lower temperature or actually the breeding reaction?

How far apart is the fusion temperature from the fusion ignition temperature and how is each one defined?

Super interesting question. Something like throwing-up just isn't in the cards at those scales due to the lack of inertia and overwhelming electrostatic, Van-der-waals and other effects. (Take a set of tweezers and try to do some kind of art at those scales and you will know what I am talking about)

Even the air feels like going through molasse to an insect according to Kurzgesagt, which do research their stuff.

Yet it seems getting food out of their stomach is part of their nature:

>Ants have two stomachs

Ants have one stomach where they hold and consume their own food and another stomach to hold food they share with other ants. This allows the ants that forage for food to feed the ants that remain in the nest to tend to the queen.

Any cell can be poisoned. That includes any multicellular organism. The less surface you have per body-weight the better you generally do when poisoned. The smaller you are the less favorable your survival in exactly those scenarios. I cannot answer beyond that.

It's not that complicated as some make it out to be. You mostly have to just follow the net energy and understand that earth is a globe and rotating around a tilted axis in relation to the sun, which gives rise to a number of seasons on the northern and southern hemisphere the further you are away from the equator.

One more thing. What is temperature?

>At lower temperatures, the molecules have less energy. Therefore, the speeds of the molecules are lower and the distribution has a smaller range. As the temperature of the molecules increases, the distribution flattens out. Because the molecules have greater energy at higher temperature, the molecules are moving faster.https://chem.libretexts.org/Bookshelves/Physical_and_Theoretical_Chemistry_Textbook_Maps/Supplemental_Modules_(Physical_and_Theoretical_Chemistry)/Kinetics/03%3A_Rate_Laws/3.01%3A_Gas_Phase_Kinetics/3.1.02%3A_Maxwell-Boltzmann_Distributions

Okay so temperature has to do with energy and virtuall all comes from the sun.

Then the main determinant is:How much energy is reaching the surface of which material for how long and how much is radiated back into space. Let's assume the surface is asphalt since > 90% of us are living in cities.

>Water has a very high specific heat. That means it needs to absorb a lot of energy before its temperature changes. Sand and asphalt, on the other hand, have lower specific heats. This means that their temperatures change more quickly.

So asphalt and concrete heat up very fast and release a lot of that heat very fast. Similarly to a desert. In Winter there is just much less heat to begin with and that heat is quickly irradiated away.

Look at this:Google images: https://www.google.com/search?q=energy+net+flow+earth+albedo

This is not enough to create a weather model, but it will make you understand the temperature range of winter vs summer.

Do you have more information on the parasitic intermediaries found in salmon?
