Re: How long can a person survive in a low berth?

And there were the sleeper ships that colonised the Islands sectors. That would support the view that low berths could be used to keep somebody alive for centuries at a stretch.

Re: How long can a person survive in a low berth?

TNE mentioned people who had survived in low berths in automated shelters since the release of the Virus. So, we could be talking 75+ years here.

Re: Where is the non-nuclear EMP?

The ship - and the fireball - are essentially free-floating in space. There is no ground plane, merely areas of different electrical potential. Is the ship at a higher or lower potential than the plasma from the explosion (caused by vapourisation of bomb casing, unfissioned nuclear material, filler)...

Re: Where is the non-nuclear EMP?

This leads to another question: If Mongoose nuclear missiles don't do EMP damage to spacecraft, why not? There might not be an atmopshere to carry charge, but on a hit that doesn't englobe the whole ship, there should be a potential difference across the ship itself ... unless I don't understand ho...

Re: Clone origins

In the past I've toyed with various ideas on clones. At the minute I lean towards a model based on random recombination of DNA to ensure a variety in the supply of new citizens. But there's no reason why Friend Computer would not maintain a database of appropriate DNA templates. There's a lot of pot...

Re: Fusion Powered aircraft

The biggest signature of a nuclear strike is the EMP as that can be detected from a long ways away, so EMP blasts are often treated as a potential nuclear strike with all of its ramifications. In order not to trigger nuclear defenses the emp device would have to be a much smaller devices and would ...

Re: Fusion Powered aircraft

EM at weapon scale has the same signature of a nuclear strike so would be like firing a bb gun at someone with a shotgun under 10m. If you're talking pure EM, then yes but minus the heat, pressure and radiation effects. If you're going nuclear, what you really want is an exo-atmospheric burst to ge...

Re: Fusion Powered aircraft

Using Realism Overhaul you too can create the most ridiculous cold war nuclear weapons concept. Project Pluto & SLAM (Supersonic Low Altitude Missile) would have a cruise missile flying propelled by a nuclear ramjet. Ah, I love the madness of KSP. But it's the staging that I have problems with.

Re: Fusion Powered aircraft

All I see in that video is a standard chemical-assisted launch for a missile. I recall that the Soviets pulled a similar stunt in the 1950s by declaring that they had flown a nuclear-powered bomber. It will be interesting to see if they have solved the problems of hardening the flight electronics ag...

The Super Swift was the hyperlight version of the Eagle. It was doubly imaginary as it was an illusion created by the aliens in The Bringers of Wonder. The Swift was the one that appeared in Brian the Brain. Officially it was described as a support ship for an expedition that went missing. There are...

If looking at the Eagle design, don't forget the Hawk - the dedicated fighter equivalent.... Anyway....if it's about 30m long, then the photos (given some highly suspect measuring and proportions) suggest it's got a beam of about 8m and a height (not including 'feet') of about 5m. Which looks about...

As someone who served on a US nuclear powered submarine for four years, I can certainly attest to the smell. The interesting thing is that you don't really notice it when you are underway. It is after you come back into port that you notice it. My wife used to make me change clothes in the garage b...

Nope. Taking a look through my textbooks, the most energetic fusion reaction going (deuterium and helium-3 making helium-4) will release 14.7 MeV per reaction. A standard uranium-235 fission reaction will release 169 MeV per reaction. So, uranium-235 releases 11 times more energy. Now, assuming you ...

Re: Shipboard Life

The interesting thing, however, is the fact that this thing doesn't need refuelling. Using current technology, this thing can go without a refuel for upward of thirty years. A future ship of the stars having to refuel its power plant once every fourteen days sounds somewhat like a backward step by ...

But sleeping off time dilation makes no real sense... It's going to occur no matter what. So sleeping during the trip, time would still go on. Unless they are going to be awake for long periods (many, many months) then why use stasis? A trip of a few weeks or months would most likely be done while ...
