Fuel for Vehicles

Postby keravon » Fri Apr 13, 2018 12:49 pm

Hi Guys,

I'm struggling to find any info in the core rule book on Vehicle fuel. Cost and type.

Plenty of info for star ships but nothing for vehicles. Any help much appreciated.

Thanks

Off hand, I think it's concerned with increasing range of operations, and by implication, fuel capacity.

Under Customization on page 46 they have Fuel efficiency and Fuel capacity to increase or decrease the range. They greatly simplified vehicle design by having the chassis type come with a standard motive type whose range is based on Tech Level. Whether gasoline, wood or Fusion Plus, this is how far the vehicle will go on a fill up. If you want complex, try Striker, Fire, Fusion & Steel or MegaTraveller.

I would say it depends on the world and the application.

The design system for vehicles is note very detailed, the fuel type is very much left up the Referee.

We know that with current technology we can build motor vehicles that run on various hydrocarbons (oil-derived, coal-derived, agriculture-derived), hydrogen, and batteries.

A vehicle carried on a spacecraft would likely use hydrogen or batteries, rather than difficult to source hydrocarbons.

Hydrogen is more difficult to store than liquid hydrocarbons. It requires cryogenic storage, hydrides, or high pressure tanks. Hydrogen molecules are tiny, and tend to diffuse through a lot of materials that are otherwise gas-tight, and reacts with some metals; for example, it dissolves into iron and most steels. It also has a wider range of explosive mix percentages in air. In short, it requires a lot more special handling.

On the other hand, it's a lot easier to generate without biological sources, and it's much better as a fuel cell fuel.

Quite, but spacecraft already carry large amounts of hydrogen and are often equipped to routinely find and extract more. Storing LHyd seems to be a solved problem.

Refined hydrocarbons such as petrol or alcohol on the other hand would have to be sourced from an industrialised source possibly many lightyears away.

I think originally it was battery packs.

Recharging would be easier, if possibly longer depending on the source.

Vehicle handbook has an info block on typical power plants throughout the TLs.
