why can not simply explode an atomic bomb inside a recint with plasma and hydrogen so the temperature and power generated will make the
fusion working

Because an atomic bomb would blow the reactor apart. And the city it's in.Rfael said:why can not simply explode an atomic bomb inside a recint with plasma and hydrogen so the temperature and power generated will make the

It is not that anti-matter can be found somewhere and can be used. Its production requires energy. And as in every process that converts one form of energy into another form of energy, there will be a loss of energy.sbrothy said:How about using tiny amounts of anti-matter? Would that be more realistic?
EDIT: [I'm ofcourse a layman if that wasn't obvious from the question.]
I'm aware there are no AM-mines anyhere (Avatar nothwithstanding), but, just perhaps, the AM amount needed would be small enough to make the process worthwhile? And I meant just to get the process running.fresh_42 said:It is not that anti-matter can be found somewhere and can be used. Its production requires energy.

The problem is not to achieve a single fusion event, the problem is to keep it going while being contained. Containment is necessary to be able to use the produced energy in some subsequent process. Otherwise, we would only have reinvented the H-bomb.
A reactor is not a bomb. You don't want to release a year or so's worth of energy all at once; you want to release it over a year. A bomb won't do that.Rfael said:i mean a fision bomb to generate a fusion like in the hydrogen bomb
The Sun's fusion has many interesting characteristics. Such as, the core only produces 276 W/m^3, which is about the same as a compost heap! The fusion in the Sun is very slow, which is nice because it afforded life the opportunity to evolve. The key limiting step there is the creation of deuterium from hydrogen (creating neutrons, basically). All fusion reactors on Earth start from deuterium or tritium, neatly avoiding this difficult step.Vanadium 50 said:It is perhaps worth pointing out that plasma temperatures and pressures similar to the sun's core won't cut it. Sure you get fusion, but the sun uses less than a billionth of its fuel every year. A giant power plant that produces 1 watt is unhelpful.
To be commercially viable you need to do a billion times better.
Actually, the goal of a nuclear reactor (fission or fusion) is to produce heat in order to produce mechanical energy to drive an electrical generator to produce electricity for whatever purpose deemed necessary to one's economic condition, or making stuff, transporting stuff, buying stuff, or entertainment.FinBurger said:So it's a challenge to keep the heat in.
Using an atomic bomb to initiate controlled nuclear fusion is impractical and unsafe due to the uncontrollable nature of atomic explosions. Atomic bombs release a massive amount of energy all at once, without the possibility for modulation or control. Controlled nuclear fusion, on the other hand, requires precise control over the fusion conditions to be sustainable and safe for energy production.
The fusion process in an atomic bomb is uncontrolled and designed to release a large amount of energy in a very short time, primarily for destruction. In contrast, a fusion reactor aims to maintain a controlled, steady-state environment where fusion reactions occur at a rate that allows for continuous energy production. This requires maintaining extremely high temperatures and plasma confinement, which are not considerations in the explosive environment of a bomb.
Yes, there are experimental technologies like inertial confinement fusion (ICF) that use the concept of rapid compression and heating of fuel to achieve fusion conditions. However, these do not involve an actual atomic bomb but rather use lasers or other means to compress a small pellet of fusion fuel to initiate fusion. The process is highly controlled and vastly different in scale and purpose compared to an atomic explosion.
Using an atomic bomb to initiate fusion would pose extreme safety risks, including the release of large amounts of radioactive material, the potential for catastrophic destruction, and the uncontrolled nature of the energy release. Additionally, it would be impossible to harness the energy produced in a useful way, as the explosion would not allow for the gradual conversion of energy into electricity.
Current fusion research focuses on methods like magnetic confinement fusion (MCF) and inertial confinement fusion (ICF), which aim to control the plasma and maintain the necessary high temperatures and pressure conditions in a stable, sustained manner. Techniques involve using strong magnetic fields to confine plasma in devices like tokamaks and using lasers or ion beams in ICF to compress and heat fusion fuel. These methods are designed to maximize control over the fusion process to safely produce energy.
