Why can't we control the power of fusion???

Question

Thanks for your answer...Tom Science 4

Answer 1

Fusion power is difficult to control because of the temperatures involved which are greater than can be contained by any known material. Fusion reactions are, however, being contained by massive magnetic fields and a small experimental fusion reactor has been built but used more power than was produced. Another experimental fusion reactor, ITER, started being built in 2005 and will produce many times more power than is consumed.

Answer 2

To a certain extent we can control the power of fusion. Many different menthods have been used to produce controlable fusion reactions such as magnetic confinement and laser implosion. However, what we can't do at the moment is convert this power into enough electricity to make it energetically efficient (i.e. we need to put in more energy to produce the reaction than we get out in electricity). This will hopefully change in as technology improves in the future.

Answer 3

Who says that fusion cannot be controlled? In the nuclear reactor rods of boron and cadnium are used as moderator which slows down the fast moving nuetrons resulting the the fusion or chain reaction proceed at a desirable rate.

Answer 4

It's pretty tricky. You've got a great deal of heat and pressure to maintain the fusion reaction and then you want to get some of the energy out of it. See the attached link for more.

Answer 5

Control the Power of fusion? Well, it's simple... We can't hold the particles literally... If we can hold the particles we can dictate the degree or power of collision that makes them fused...

Answer 6

The simple answer: too much power. Anything we can build with present technology won't stand up to it.
