Hot Air Balloons for Artillery spotting

My point was that the balloon is being held up be whatever gas is being used at the time-- hot air, hydrogen, etc. So gravity would be accounted for. What would remain would be the inertia the propeller would be pushing against. The smaller the balloon, the less inertia and the easier the prop's job.

It would seem to me that my proposal would be lighter and simpler than a piston steam engine which might make it suitable for this application.

To those who are aware of Rocky & Bullwinkle, it might behoove someone to find a source of Upsidasium.

And then they could drop bombs made with Hush-a-Boom.

Or for those who remember "Brass", "Hardacre's Silent but Deadly"

Our heroes Gidney & Cloyd phase out whenever Merlin enters Nimue's cave.

Thanks Guys

It's nice to know that I'm not the only adult who has spent WAY too much time looking at cartoons

Hey, I was 9, in November 59.

Zuffering Zucatash.
Beep-beep.
Zoinks and jeekers.
Exit, Stage left.

And I got married on 10/Aug/1959.

Then worked for two years in London, England !

And I STILL like looking at cartoons

This provides no information about the air density, since that depends on the quantity of air. Probably no air generator, as the native plants and animals co-exist along with the Terran imports, so the atmosphere was pretty much the same.

Ooh, lower gravity and overall colder, that´s GOOD conditions for balloons.

If air density is also above earth, then flight could be really easy. Hanggliders or manned kites might be realistic even with just the most simple materials and experimentation.

So it seems that all the best fantasy authors are trying their hands at steampunk genre lately. I'm quite certain that RFC could wright something trully epic and amazing if he was to start something up.

Problem he has way too many serries that are still ongoing that starting something new just to play with steam powered machines and magic would slow everything down.

Enter the Safehold serries, they have steam engines now, they have sufficently advanced technology that is indestinguishable from magic. They can easily(if the author chooses) have fleets of airships duelling it out in the ski, while steam tanks roll through the feilds and massive Battleships and Dreadnaughts trade broadsides on the seas.

Well maybee not in the next book or two, but certainly in a decade safehold time.

Hummm...Is this the same think as to say that all of the best science fiction authors are full of hot, humid air??
