MT: Robots fuel weight & cost

[snrdg082102]

MT: Robots is using liters in place of kiloliters and kilograms in place of metric tons.

To make sure I have this straight, I suddenly became confused, here are my conversions for the units.

First to make sure I've got the right conversion I'm going to show a fusion plant TL 10

TL   Description   Power Out   Weight    Volume  Consumption
10   Fusion         2,000 kW   4,000 kg  2,000 l   3 l/hr

A fusion plant uses hydrogen as fuel the weight and cost are found on MT: RM p. 83. Weight, is in tons, which needs to be changed to kg and the cost units are left as Cr. The weight and Cost is based on kiloliters of fuel, which should be changed to liters.

Hydrogen Weight = 0.07 tons per kiloliter of fuel = 70 kg per kiloliter of fuel = 0.07 kg per liter of fuel.

Hydrogen Cost = Cr 35 per kiloliter of fuel = Cr 35 per 1,000 liters = Cr .035 per liter of fuel.

Have I got the right numbers?

Yes, you have the right numbers.

Note that you can install fractions of a kilolitre of fusion plants, except that you need to comply with minimum volumes - so at TL10 of course this won't be possible.

There are a couple of examples of larger robots that go with fusion plants over fuel cells. The primary reason is the power requirements usually for larger thrust based robots. But fusion plants also have a duration advantage in hostile environments as fuel consumption does not need to be multiplied by 9 (or is it 8? rule book isn't in front of me) to account for the oxygen needed by fuel cells.

Thanks for the reply and confirming I'm on the right track.

The hostile environment fuel consumption factor is indeed 9, and good thing you mentioned the fact that fusion plants aren't affected.

New part of the question concerning the hydrogen cost for the Starport Mechanic Robot.

If a liter of fuel costs Cr 0.035 then the fuel cost is 53.74 liters x Cr 0.035 = Cr 1.8809 right?
