Daedalus Model Update

posted by admin on October 14, 2012

Terry Regan is building a detailed model of the Daedalus craft. Here is a brief update of his latest progress…

So far I have made the reaction chamber, the support structure and the induction loop.

I test fitted the induction loop to the reaction chamber, and at first I was happy with the way it was looking, but there was something that didn’t look quite right. It turned out that the distance between the loop and the chamber was too large, so I removed all the “V” shape brackets and made shorter new ones from .8mm brass rod, and soldered on the top locating pins so that it would make a good solid joint. I reassembled the loop to the chamber and: perfect! – it all looked right.

Next step was to make the parabolic reflector. This was made out of 1.5mm styrene card, and the centre was cut out for the pellet injection gun. I marked out where the four propellant tanks are to be fitted, drilled and added four rods for the tanks to be attached to. I moulded a funnel for the pellet injector gun by plunging a brass drawer knob into soften styrene card, and then glued this to the centre of the reflector.

The four fuel/propellant tanks are Christmas baubles, cleaned up and detailed. The support structure that fits around the payload bay was made from 1.2mm styrene rod, and I drilled down the centre with a .5mm drill and fitted 15 Amp fuse wire for the locating joints.

  1. this is Exciting.
    I hope I’m still alive when this baby get’s to “Fly”

    Does anyone happen to know off the top of their head what the energy relationship is between the cost to produce a given mass of anti-matter and the energy it releases when annihilated? Thanks in advance,

    Also, can a stream of 11Boron and LH2 fusion product at about 11 terra watts be used to generate antimatter? How so? What would be the rate of production?

      Been watching a little Star Trek lately? Well, when a hydrogen atom collides with its antimatter counterpart it releases the matter of both atoms in energy. The energy released would be 3.008486698 X 10^-10 joules or 1.87774927364454722 X 10^9 electron volts.
      The cost of creating an antimatter hydrogen atom is about $62.5 Trillion per gram of anti hydrogen. This comes out to less than a penny for every electron volt or $0.0000000001046060279 per anti hydrogen atom. (I have not incorporated the cost of the regular hydrogen atom because it would be so small that it would have little to no effect on the cost of energy production.) This would be 1.79506794 X 10^-1 electron volts for every dollar.
      As to the process of antimatter, I have no knowledge on the subject. But there is your ratio: 1 dollar: 0.179506794 electron volts.
