Friends,<br>
<br>
I ran some numbers through the calculator. Used one Kg in order
to get a unit centripetal force -- ie force per Kg,... used 0.1c
for the velocity, and 100,000,000 miles for the ring radius
(rounded up the 93,000,000 mile earth orbit radius) and got 57
times the force of 1kg at one gee. <br>
<br>
For launching solid stuff, this a manageable problem right?.
Humans, using a temporary liquid breathing medium (fluorocarbons)
and immersed in liquid might be able to tolerate this gee load.<br>

Well, humans tend to get squashed around this acceleration. The
world record of survival was 46 Gs. <br>

But in my problem I am looking at specially designed high
acceleration tolerant solid payloads - think bricks of diamond and
nanomachines. <br>
<br>
Basically I am trying to estimate the limits of how quickly a single
Dysoned star could spam the universe with colony probes. Most of the
analysis has been done already, but I would like to be certain that
the launch systems are feasible. <br>
