How much power for artificial gravity?

[EldritchFire]

HG 2e, page 15: "Basic Ship Systems: This includes everything a ship needs for day-to-day operations, including artificial gravity, heating, lighting and life support. The number of Power points needed for basic ship systems is equal to 20% of the total tonnage of the hull."

How much of that power is for artificial gravity? If you use the non-gravity hulls (pg. 10) you don't have to worry about power for a system you don't have.

Any ideas?

From the original text on power:

Turning off grav plating saves .1 x tonnage in power points.

Which would mean maintaining artificial gravity would suck up half basic, not leaving much left over for inertial compensation and recharging my iFone.

What book and what page? I can't find that passage.

You wont, never made it into the book. Was a bit originally written when first bringing in the idea of adding a power requirement.

Ah, hence what was meant by 'in the original text'. Gotcha. Half of the power being for gravity makes sense to me, and will use that as a benchmark in my future designs.

Thank you, AndrewW!

You can run with only half the basic system power, and you still have artificial gravity. So whatever power the artificial gravity uses is less than half of the ships basic power requirements.

There's life support, possibly climate control.

The lights, washing machine, television ...

Since the rating is per ton it seems to me that you could turn off grave plating in various sections while maintaining it in vital section such as the bride and engineering.

for example, a 10 ton bridge would have a power rating of 1 pt to maintain gravity/compensation. So cut back base power. figure up how many power points that frees up...then subtract 1 pt to keep the bridge plates powered up.

also since a grav hull is twice the price of a nongrav hull we could assume grav plating costs 25Kcr per ton of ship, and has a power rating of 0.1 pts per ton. no extra tonnage is involved since it is incorporated directly into the structure of the hull.

in theory if you wanted to build a ship that had grave plates in the bridge area to act as acceleration compensation you buy a non-gravity hull and then add the cost of grav plates, and allow for additional power demand for the tonnage of the bridge.

For long haul non gravity ships you could add plating to the Common areas so the crew could spend a few hours a day in gravity to alleviate the effects of long term zero-gee.

A mercenary cruiser doesn't need artificial gravity, so long as it keeps on accelerating at 1-g.

very true, but if it has to maneuver in combat the Gravity control comes in real handy.

That Swedish meatball has an acceleration of three, so conceivably at half speed there are no penalties to the performance of the crew, they should be sitting down at two, and at three it would be like the Space Shuttle taking off.
