In order to start a Fusion reaction you need a high energy spark which is provided by a nucluer fisson denonation

Wrong its not the energy input, its the energy needed to confine nucleur Fuison. Inorder to start a Fusion reaction a fission reaction is used as a park, which is seen in the hydrogen bomb. However you get a miniature sun on Earth, (damn hot) so inorder to contain this magnetic field needed however needed to confine it would be the same energy as the fusion itself

Jomomma, you should read up on how hydrogen bombs work before posting. Since you apparently missed my earlier comment, I'll repeat: Hydrogen bombs use a fission explosion to compress a secondary fuel, creating a much larger fusion explosion.

its too bad that the 1st one that isnt a prototype isnt expected to be done until 2035...

the hydrogen bombs are different. they use nuclea FISION

Fusion occurs in the sun because of its massive gravity and heat. With enough energy and heat you could probably make fusion occur here on earth, but the cost of the energy put in would outweigh any output.

@chairde
Fusion has been experimented and to confirm what krazyzeeban said, its an uncontrolled mechanism as in the case of the bomb. The main problem with fusion in a controlled manner is containing the plasma. Magnetic fields haven't been entirely successful. Nevertheless fusion is a renewable source and just as Solar was once very inefficient with p-v cells and is now becoming more feasible with parabolic mirrors and etc, fusion technology will probably advance for electricity generation.

Just because it uses more energy now doesn't mean that it'll always be that way. If you give up just because your first experiments don't work out perfectly then we'd still be in the stone age.
ITER is expected to produce more energy than it consumes, and other reactor designs theoretically will produce more energy than you put in. Solar power alone isn't enough to satisfy the worlds demand for energy.

It is a good wish to have but it is simply not feasible in reality. Those experiments are bogus and the Europeans are not going to succeed. Control of the chain reaction is important and also why have an energy source that takes more energy than it will produce? In any case, I wish the Europeans well. Go solar instead, God has already worked out the control problems and other issues.:-)

The hydrogen bomb uses a fission explosion to compress a secondary fuel, resulting in a fusion explosion. Read up on hydrogen bombs and come back. I say again sir, JET has already performed a fusion experiment generating electricity. The problem with fusion power now is that it requires more energy than we get out of it, but it's still fusion. ITER is expected to generate more power than was input. Fusion power is much safer and cleaner than fission, something like Chernobyl is impossible. |
