A long-term antimatter storage device that may be energized by a low power magnetron and can function autonomously for hundreds of hours on the energy provided by batteries. An evacuated, cryogenic container is arranged with a source of positrons and a source of electrons positioned in capture relation to one another within the container so as to allow for the formation of a plurality of positronium atoms. A microwave resonator is located within the container forming a circularly polarized standing wave within which the plurality of positronium atoms rotate. Radioactive sources for small stores and low energy positron accelerators for large stores are used to efficiently fill the device with positronium in seconds to minutes. The device may also be arranged to provide for the extraction of positrons. A method for storing antimatter is also provided.

US scientists get glimpse of antihelium
Scientists in the US produced a clutch of antihelium particles, the antimatter equivalents of the helium nucleus, after smashing gold ions together nearly 1bn times at close to the speed of light.
The discovery of antihelium at the Relativistic Heavy Ion Collider at Brookhaven national laboratory in New York will aid the search for exotic phenomena in the distant universe, including antimatter versions of stars and even galaxies.
Antimatter looks and behaves like normal matter but has one crucial difference: particles of antimatter have an equal and opposite charge to those that make up the world around us. When antimatter meets matter, the two annihilate one another, leaving nothing but a burst of energy.
Ok so we are a tiny step closer to potentially solving the riddle of the Big Bang. If such an event actually really did occur. We are still a good deal away from Matter-Antimatter propulsion drives as in Star Trek.
But still a bit closer.
Physicists observe antihelium-4 nucleus, the heaviest antinucleus yet
-- In 1932, scientists observed the first antimatter particle, a positron (or antielectron). Since then, scientists have observed heavier and heavier states of antimatter: antiprotons and antineutrons in 1955, followed by antideuterons, antitritons, and antihelium-3 during the next two decades.
Advances in accelerator and detector technology led to the first production of antihydrogen in 1995 and antihypertriton (strange antimatter) in 2010. Now, scientists with the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory have observed another state of antimatter for the first time: the antimatter helium-4 nucleus, which is the heaviest antinucleus observed so far.
The WMAP 7-year results estimate that 4.56% of the universe's mass is made up of normal atoms
The WMAP 7-year results estimate that 4.56% of the universe's mass is made up of normal atoms. Thats huge % of exotic atoms out there, here, everywhere. There is no need for a mine.
As a new study shows, general relativity predicts that the gravitational interaction between matter and antimatter is mutually repulsive, and could potentially explain the observed expansion of the Universe without the need for dark energy.
