Question: Is it possible to contain and use anti-matter as fuel and use it to power a spacecraft? If it is possible can it be used as a destructive force?

  1. With current technology it isn’t possible to contain antimatter on any significant scale. Most antimatter we can create is charged – and so has to be kept spinning around in a big circle in high vacuum. Some researchers have succeeded in making “anti-hydrogen” and slowing it down so that is at rest – but only a few atoms at a time. You’d need a lot more to use it as a fuel!

    If we work out how to contain it on a large scale we could use it as a fuel and as a destructive force – but it requires *a lot* more energy to make it than you would get out of it. You’d be best to stick to nuclear fusion (same process as in the sun) – it’ll be a lot easier, and more efficient.

  3. I agree with Matthew on this one: the energy and effort involved in containing anti-matter is far greater than the benefits you’d get using it as fuel. Nuclear fusion has more potential and should be easier to do. However, fusion – where two atoms fuse together to form a bigger atom and release lots of energy in the process – is still a very inefficient technology. The best we have been able to achieve is “break-even” same energy in as out, and even then it has only happened a small number of times.
