Even with the improved antiproton production and storage capacities expected soon, this amount of antimatter is beyond our reach.
Again assuming a three-order of magnitude improvement in antiproton production efficiency, these gains are near break even in terms of net energy flow.
Antielectrons or positrons are difficult to store in this way, so antiprotons are stored instead.
For a hypothetical plasma composed of antiprotons and positrons, a potential dip would occur.
Currently, antiprotons can only be stored for a few weeks and production is very low, but the problems with the storage and production are engineering problems, not physical problems.
Iridium is used in particle physics for the production of antiprotons, a form of antimatter.
For example, an antiproton and a positron can form an antihydrogen atom, which has almost exactly the same properties as a hydrogen atom.
Whereas the common hydrogen atom is composed of an electron and proton, the antihydrogen atom is made up of a positron and antiproton.
