We don't know the properties of dark matter particles, we only have model hypotheses. For the usual ones (e.g. weakly interacting massive particles (wimps) or Axions) there is currently no tech to harvest them (otherwise we'd have discovered them) but I can speculate. For wimps, one could imagine a stream of high energy particles which would force them to undergo weak interactions. All unimaginably expensive and inefficient. I would figure a 1x1 m prototype to involve a wakefield particle accelerator which costs millions and needs a few megawatts to operate 🤣
But who knows, maybe I am missing something ingenious
sorry, that was me asking stupid questions. Dark matter/energy are placeholder names for the as yet undiscovered. DOH!
Yes, all we know is how much of it there should be (to cause the observed excess gravitation) and roughly how fast it would be moving, although that's where you have to choose a hypothesis. The conservative estimate would be our speed of movement through the galaxy.
