starship-design: Quiet starship-design List

Hi Andrew,

Solutions that have been given:

1. Create a dust/plasma cloud in front of the ship and push it forward (and
replenish it when it dilutes. Assuming it is a plasma cloud, you may be
able to contain it a bit by using magnetic fields.
The idea is that the plasma cloud will act like Earth's atmosphere and
diffuse any incoming particles or dust.

2. Use powerful lasers that ionize/evaporate anything in their beam. Then
use lasers and/or magnetic fields to push the ions aside.

3. Just make a thick solid shield and hope that it can withstand the impacts.

It is permanently down at "dds.nl" but can now and hopefully long hereafter
be found at:
