    How could we collect the antimatter near earth?

    Can we do it? I want some.... for my new interplanetary cruiser.

    It would be collected in very small amounts from Earth's magnetosphere. Jupiter and Saturn would give higher yields.

    Unfortunately, you really don't want to use it to power an interplanetary cruiser. On one hand it seems like an ideal propulsion force, but you will never get enough to make it remotely worthwhile. It's hard to get, because it usually annihilates with matter, and it's hard to store, for the same reason. So just gathering enough together to make it into a viable fuel would be a nightmare. Just for perspective, there is an antiproton beam at CERN, and to date they have only produced a nanogram or so of antimatter.
    As above, so below

    He didn't say he wanted a large cruiser...

    I want a fleet of them, just small enough to be be swallowed whole by a tiny dog.

    Thanks. How much higher yields? Do we know if it is being produced in enough quantity anywhere close to be an actual resource? As I understand it antimatter requires magnetic fields and a perfect vacuum to be contained since you don't want it coming in contact with normal matter. Sounds difficult and expensive. How would you collect it? I wonder how much is actually being produced Naturally by magnetospheres, planetary or otherwise....or.... the Sun? The energy required to make it ourselves seems to rule it out as a feasible alternative fuel.... If "Natural" production was on a great enough scale somewhere though, we could probably figure out the details of collecting and using it eventually...

    I’ve read about this before, but try entering “harvesting antimatter in space” in google. A few links:

    https://www.centauri-dreams.org/2016...ting-in-space/

    The available amount would be very small. Jupiter would be a better harvesting location than Earth because of the much more intense magnetic field. Maybe enough could be collected for antimatter catalyzed fusion rockets. Storage would need improvement over current hardware.
