Warp efficiency of one equals "100 meters in one nanosecond." Anyone else ever see this statement?

[warstar]

I recall reading somewhere that stated a warp efficiency of one was equal to a stutterwarp vessel in deep space travelling "100 meters in one nanosecond." I calculated that be to about 333 times lightspeed. I checked several 2300ad books that I have and couldn't locate that statement.

I know that officially a warp efficiency of one equals one light-year per day.

Well, arguably, that's 365 times light speed. So, back fill the numbers and round it up/down something 10 fingers would enjoy.

Whomever said it, WarStar, was probably quite wrong. I remember it from the old 2300 Mailing List.

Nominal Seconds per year 365×24×360 = 315360000
Wikipedia claims 1 LY = 9,460,730,472,580.8 km
crunching the numbers in QB64 due to extensive precsion...
lm/ly 525600
m/min 17999867718
ls/ly 31536000
m/s 299997795.3

that's about 300m per µsec, or 0.3m/nsec

Efficiency of 1 in deep space, mind.
In system is slower IIRC (See quote)

Here's the code

REM QB64
REM && is 8 byte integer, signed (±2^63)
REM ## is 32 byte float - serious overkill...
m&& = 365 * 24 * 60
s&& = m&& * 60
ly&& = 9460730472580800
mpm## = ly&& / m&&
mps## = ly&& / s&&
Print m&&, s&&
Print "lm/ly", m&&
Print "m/min", mpm##
Print "ls/ly", s&&
Print "m/s", mps##
cb$ = "lm/ly" + Str$(m&&) + "m/min" + Str$(mpm##) + "ls/ly" + Str$(s&&) + "m/s" + Str$(mps##)
_Clipboard$ = cb$

The distances that the stutterwarp can travel, however, are very
small. One cycle of the drive moves a ship less than a few hundred
meters. By cycling the drive very rapidly, however, the ship
can travel vast distances in very short times. The speeds commonly
achieved depend on the output of the powerplant, but approach
several light-years in a day.
Stutterwarp drives function best in unstrained space; within a
gravity well, their efficiency drops enormously. At a threshold of
0.0001 Gs, maximum speed for stutterwarp ships drops below
lightspeed. In truly high gravity fields (around planets), speeds are
reduced to efficiencies less than chemical rockets. As a result, stutterwarp
is efficient as an interstellar and interplanetary drive, but
ordinary methods are still necessary for travel between orbit and
world surfaces.

As a side note - since I'm too lazy to dig out the other thread - the efficiency losses are the ONLY reason normal weapons work in 2300 combat - because it was (as with the core CT it spun off from) assuming combat occurring only in systems. Oh, and that threshold? 0.00098m/s² .... about 1.5× to 2× the gravity of Sol at 1 AU (0.0005 to 0.0006 m/s²)... so it's hit around 4 AU - that's Asteroid belt.

Do I have too much time on my hands? No, but only because I profligately spend it doing such nerdish stuff.

No.

Spinward Flow has too much time on his hands. Gratefully, he shares it with us.

Well, I am a believer in the notion that Knowledge Shared Is Knowledge Multiplied.

No.

It's hard to believe such a calamity.

The IAU’s definition of “light-year” uses a Julian year [symbol “a”] of 365.25 days, and the speed of light in a vacuum [symbol “c₀”] has been defined since 1983 as 299,792,458 m⁄s exactly, so a light-year = 365.25 d⁄a × 24 h⁄d × 60 min⁄h × 60 s⁄min × 299,792,458 m⁄s = 9,460,730,472,580,800 m⁄a = 9,460,730,472,580.8 km⁄a, which would seem to be the basis of the Wikipedia number.
