Vehicle Construction

Volume is given in vl, which represents about 10 liters of vlume or 0.01 cubic meters of space

This is in the design sequence chapter!

Is this 'vl' unit just used for vehicles, or for starships as well? I can imagine the numbers getting quite high if it's used for the latter
 
Displacement is used for large vehicles like starships and spacecraft.

One displacement ton is equal to the volume taken up by one ton of liquid hydrogen. This is approx. 14 cubic meters or 1400 volume.

If you're trying to duplicate existing Real World vehicles, this ends up being about two times too large. I use 5 liters per vl and find the vehicle designs match very well.

The volume of my ground car (a Subaru Legacy) is about 9m^3. I've used the design system to build a number of ground vehicles and with all of the required components, it comes out at about 2000vl (+/-) or 10m^3.

At the other end of the scale, a 20 foot bus used for 25 standing passengers is about 40m^3, where in T20 the design came out about 7,500vl or 37.5m^3

And even larger, a Mack truck with trailer I found to be about 200m^3. The T20 design was 49,000vl or 245m^3 (mine includes a sleeper cab and a fusion power plant).

A Honda Civic? A car that works as a spare "tire" for normal cars? :D

Ive noticed that in the vehicle design system there is a little problem.

you design a vehicle by its size (vl). But there is nothing about its Weight/Mass????

It may be important for some vehicles and robots.

such as when they are crossing certain terrain.
or perhaps at a bridge.

Using just the size will not work as a heavilly armored mini-tank (2000vl) has got to be much heavier than a car (2000vl).
:confused:
another thing that i noticed when going through the design system is for robots.
:confused:
in the old robot supliment the human sized robot was based on a 100 liter torso chasis if i remember corectly. which would be 10vl in the new system if each vl is 10 liters.
:confused:
the personal service robot is 100vl wich is 10 times the size of a typical human torso.
:confused:
if the perci is 100vl then that means that it is 1000 liters thats very big. A 55 gallon (liquid) barrel/drum is 189.270589 liters
:confused:
so perci is the size of 264.172052 gallons.
does anyone else see the problem??
:confused:
or look at it this way if say the servant robot was 3' wide, and 1.5' thick (front to back) then it would have to be 7.777' tall. this is big not to mention the weight which i have no idea. even if he was not particularily heavy say the same specific gravity as water. it would then weigh 2204.622622 pounds or 1000kg. which doesnt seem very handy for a servant robot. my guess is its much heavier and does not float. :confused:
 
Actually, thats correct is seems: Half the volume to 5l or 0.005 cubic meters. Larger cars with the same capacity would take more passengers and have better "armor"...

I have been looking over the Computer building rules for a while now, and I have figured out you cannot build a reasonably sized Cyber Computer for placing into a person's body. Even for the best CPU at TL 20 (4 higher, -40% volume) it takes 81 cubic centimeters of volume per 2.5 points of CPU... Kinda harsh...

Now I'm going to have to build an even smaller computer type and TL for something about 1/100th the volume... Perhaps say it can only be used when it directly merged into the brain. Then make some cyberware rules where you have a level 1-9 cybercomp with differing Constitution limits to have them...
 
I use tjoneslo's 1 vl = 5 liters. This is used as the storage/transportation volume, and I use 1/2 that as the actual volume. To determine weight, I use 1/2 the listed vehicle volume at 1kg per liter + 1/2 the armor volume at 2 kg per liter to determine weight.

Thus 300 vl Medium Battle Dress weighs 1080Kg (150vl x 5 liters x 1Kg + 33vl (1/2 armor vl) x 5 liters x 2 kg = 1080Kg).

This seems to work out well, and since the actual volume is 750 liters with this formula, this sucker does not float. You can make vehicles float by adding empty "cargo" space which will lighten the vehicle by 1kg per liter of volume.

:cool:
