There may be some possibility of mining CT from the Van Allen belts--but it would be impossible to determine which particles were which.

Having had a look into the NIAC study "Antimatter Harvesting in Space" ( www.niac.usra.edu/files/library/meeting ... ackson.pdf ) just this moment I found on page 5 the information: [quote]Antiproton Production @ Fermilab
• Present: 10^11 antiprotons/hour for 4500 hours per year • Present: 27.4 M$/year for purchase of all antiprotons • Near Future: Agreement to purchase 1% of Fermilab production for an annual cost of 274 k$, plus cost of construction, utilities, and safety oversight of the Hbar Technologies research facility on the Fermilab site. • Cost per Treatment: Assuming 10^10 antiprotons per “treatment†|

Alternate anti-matter design using a positron reactor to heat up LH2.
http://www.nasa.gov/mission_pages/exploration/mmb/antimatter_spaceship.html "10 milligrams of positrons needed for a human Mars mission is about 250 million dollars" --------------------------------------------------------------------------- Unrelatedly, accelerating at 1 G it takes less than 1 year to approach the speed of light. |

I wonder if SSC would have made more...

We have anti-matter chemistry now, it seems:
But we still need heavy Lift Jupiter III http://forum.nasaspaceflight.com/forums ... ntid=13384 |

Regarding the usual absence of antimatter: what about using the usual and permanent quantum fluctuations in the vacuum? An ion might capture the electron of an electron-positron-pair - might there be a way to catch the positron magnetically that fast and quickly that it can't annihilate with the electron?

I still think the fusor is an interesting device for quantum experamentation. What do you guy's think?

I continue to have in mind antimatter propulsion - although more realistically by mixing antimatter into matter when the engine is entered.
If positrons might be captured when ions catch the electrons of the pairs and the positrons can magnetically directed into the engine then the annihilation could occur there and concentrated there... ... What about the approach? Dipl.-Volkswirt (bdvb) Augustin (Political Economist) |

I'm thinking about the creation of the anti-matter at the moment more so than anything. How are we going to create the anti-matter?
