What are scientists saying about nuclear fusion in the future?

The next stage of experimental fusion developments is to be ITER, which you can find in Wikipedia. This will be much bigger than previous installations, but still not capable of producing and exporting power, so the goal of having useful fusion power is still way off in the future.

What planet are scientist saying is not a planet?
Pluto is the planet that scientist are saying is not a planet. Scientists are not saying any particular planet is not a planet. Simply that Pluto has been reclassified as a dwarf planet.
Is atomic bomb and nuclear bomb the same?
No, I don't believe so anyway. You see, an Atomic Bomb has an explosion made of the ripping of atoms whereas a nuclear bomb is either a Fission or Fusion reaction(fission=the splitting of molecules/fusion=the joining of atoms to create molecules)Ex. The sun is a giant nuclear explosion/reaction when the atoms of Uranium molecules separate to make a fission reaction and those same atoms join with other atoms to make a fusion reaction and recreating molecules to procede to the fission stage where the process is redone again and again and... etc.Fun Fact: Only two atomic bombs have been dropped one on Hiroshima and one on Nagasaki No nuclear bombs have ever been dropped in war.-Zazzer acc;)The above is one of the most confused explanations/understandings I have ever seen. For one thing "ripping of atoms" is confused, it really is just a way of saying fission yet its use implies something different from and probably weaker than fission is happening. Molecules are not involved here either, only atomic nuclei (this is a serious confounding of chemical reactions and nuclear reactions, which happen in entirely different parts of atoms and involve about three orders of magnitude difference in energy). Another thing the reaction in the sun does not involve uranium, the sun (as any star) only operates on fusion and at its current stage of life can only fuse hydrogen into helium. There is no such thing as a fission-fusion... and repeat cycle in any star. No star can ever produce elements large enough and heavy enough to fission, only supernova explosions are powerful enough to do that. The two Fission bombs dropped on Japan in the war could equally validly be called Atomic bombs or Nuclear bombs.Atomic and Nuclear are basically interchangeable terms in this area. Both refer to energy obtained from the binding energy of atomic nuclei.There are two types of reactions involved:Fission - breaking of large heavy atomic nuclei into smaller lighter ones.Fusion - combining of small light atomic nuclei into larger heavier ones.From the 1945 Trinity test through 1951 all atomic/nuclear bombs were Fission bombs. After the 1952 Ivy Mike test, atomic/nuclear bombs could be Fusion bombs. However a Fusion bomb is very complex, needing at minimum:A Fission bomb trigger stage to generate x-rays to drive the implosion of the Fusion stage.A rod shaped Fission bomb "sparkplug" the length of the Fusion stage to ignite fusion at maximum compression of the Fusion stage.A cylindrical Fusion bomb stage.A cylindrical metal tamper around the bomb to hold it together for a few extra microseconds, to keep the reaction going and get a good yield. (Note: this tamper is usually made of depleted uranium because of its high density. however a depleted uranium tamper is able to absorb the high energy fusion neutrons and fission, making it responsible for about 90% of the yield and fallout of such bombs.)Therefor a typical Fusion bomb is really a fission-fission-fusion-fission bomb.Most modern Fusion bombs improve the efficiency of and miniaturize the fission trigger by using a hollow core deuterium/tritium gas fusion booster design. A Fusion bomb designed this way is really a fission/fusion-fission-fusion-fission bomb.All currently operating atomic/nuclear reactors are Fission reactors. Work has been going on since the early 1950s to make a Fusion reactor (as it should be cleaner and its fuel is more available), but none has reached "breakeven" (ability to generate enough energy to operate itself) let alone generate enough excess energy to operate as a powerplant.BTW, the "Fun Fact" is also completely false and confused. Many many atomic bombs have been dropped from airplanes or fired as missile warheads, beginning in 1945 and ending in either 1961 or 1962. The two bombs dropped on Hiroshima and Nagasaki were thee only ones actually used in war.Please excuse my "micro-thesis" on the subject, but there were so many things needing correction and/or clarification.
What do the opponents of the global warming theory believe?
They believe what 31,479 scientists believe: there is no man-caused global warming. They all signed a petition saying so. Out of those 31,479, about 9,000 are climate scientists.
Why is it important for scientists to use the same system of measurement?
Saying something is "14 long by 20 high" or "weighs 73.4" doesn't help at all if one person uses grams and the other uses tons.
Can ulcers affect your taste buds?
Some scientists say yes because you know how If you eat/drink something and it burns your ulcer?Well, Your ulcer will send a ,message to the brain saying,"i don't like this it burns me", and the brain CAN but might not, change your taste buds
Is nuclear fusion used for nuclear power?
No, not yet. Maybe in another 20 years when its perfected (which they have been saying every 20 years since they originally began work in the 1950s on lab prototypes of controlled nuclear fusion reactors for power generation).
What will be in the future in Mars?
Scientists are saying that it might be possible to make a base on Mars so that they can study it more often.
How can scientists make a machine that revives extinct animals?
They cant yet but there's no saying that later on in the future they will be able to
Elemets that contain high binding energies in the nucleus are likely to release stored energy through -Nuclear Fission -Nuclear Fusion -Kinetic Energy -Chemical Energy?
Nuclear fission - if large atomsNuclear fusion - if small atoms under high temperature and pressureNuclear decay - atoms of any size if unstableThe products of any of these processes usually have high kinetic energy, which is another way of saying they release heat.
What is the cause of sun's enormous energy output?
The fusion of hydrogen into helium, and the conversion of a tiny amount of mass into energy, in accordance with Einstein's equation "E= mc2". The total mass of four hydrogen atoms is SLIGHTLY higher than the mass of one helium atom. This takes place at temperatures in the millions of degrees and under incredible pressure, conditions that are only found in the cores of stars. Here on Earth, we are capable of creating these conditions, but only for tiny fractions of a second. We call it a "nuclear explosion". We _THINK_ we're getting close to creating these conditions in a more controlled manner, in reactors that may eventually be "nuclear fusion reactors", but we're probably 20 years away from being able to do that. Alas, scientists have been saying for 40 years that they were "20 years away" from developing nuclear fusion as a controlled power source. Good thing we scientists are perennial optimists!
How are nuclear energy used?
Saying nuclear energy is like saying Norwegian furniture. Nuclear power/energy is used everywhere, in 2009 20% of all electricity in the US was nuclear origin.
Is raditz a super sayen?
No he cannot. I'm not saying he couldn't become a super sayian. He just never achieved it. Only people that have achieved Super Saiyan powers are ... Goku Gohan Future Gohan Goten Trunks Future Trunks Vegeta Vegeta Jr. Goku Jr. Brolly And the Fusions. Vegito (Potara Earings) Gogeta (Fusion dance Goku and Vegeta) Gotenks (Trunks and Goten fusion dance)
What is the difference between an atomic bomb and a nuclear weapon?
Those are two different names for the same thing.There actually is not a difference in the atomic bomb and nuclear bomb. Saying 'Nuclear Bomb' is a modern way of saying 'Atomic Bomb'.
Is nuclear testing the same as nuclear weapon testing?
In common usage, yes. Its just a short way of saying it.
Will tsunami hit Pacific Ocean?
Well, some scientists answered it by saying: yes yes it will hit soon, but other scientists answered it by saying: we don't know yet if it will hit or not.
Are megalodons in your oceans?
Megalodons are a rare shark and scientists don't know yet, there are people saying yes there are and scientists saying no there are not, i have a guess that yes there are, but only in the deepest part of the oceans where nobody wants to go.....
Will we save our planet from global warming?
Who can predict the future? Many scientists are saying that we are not able to prevent some of the early changes. The G8 countries have set a warming limit of 2 degrees Celsius as their maximum, but we are already at 0.8º C.
