Low Tech vs Interstellar societies...

[Spinward Flow]

Which would you choose to use on some lower tech backwater world if you lived there?

1. Can operate on Luna or Mars with minimal modifications ... so ... interplanetary environment viable.
2. Cannot generate power without plentiful gaseous O₂ and liquid hydrocarbon supplies ... so ... NOT VIABLE on more than 1 planet at a time MOST planetary bodies in the galaxy.

I'm going to go with Option 1 of the 2 provided ...

I'm pretty sure that for the immediate future, electrical vehicles will dominate within an urban environment.

Demonstration of real world fact can be found in:

• Norway
• China
• ... need I keep going ...?

The primary issue seems to be the batteries.

You're going to need some convenient way to charge them, increase the capacity and longevity, and, not blow up.

About the ground infrastructure vs grav vehicles matter, and again resorting to MT (not sure if also for Striker), see that while the cost for most (if not all) MT listed vehicles are very expensive, because they respresent those for rough, usually self reliable and able to work with minimal infrastructure, but they can be built quite cheaper...

If you have access to it, I'd recommend you the article Affordable Transport, Part 2 (Budget Grav Vehicles) in Traveller Digest nº 20, page 41-43. There you'd find grav utilitarian vehicles well under the 6 digit prices...

You can see two examples (a grav bike and a grav APC) among my own designs (link in my signature).

If your grav utilitarian costs you about KCr 16 (against the KCr 275 of an air raft in IE), or a grav bike price is about KCr 5 (against the KCr 171 of a trasea in WHB) I guess most of your calculations are moot...

As I recall Striker, the grav vehicle design allowed relatively cheap variants.

Possibly too cheap, since the current rate is thirty kilostarbux per quarter tonne, speed and range varies to technological level constructed.

Air/ships, calculating in actual usable space, being a tenth of the cost.
