Tenses; They
are(present; and starlog parallels are deliberate) sharing a bunk for purely social reasons because she
has decided(immediate past; probably in the last half hour) she'd prefer not to be alone; but earlier they
had(more distant past, possibly weeks before, when they were training in the unfinished ship) used the faculties for other sociable interactions.
Sources of conflict: The principal source of tension is obviously between the ship and the inhabitants of the Earths it visits; because they are human, with different societies in the case of the close one's, and because they aren't, for the more distant. As I observed, I'm better at world building than plotting; I've got you to your frontier, and there are aboriginal inhabitants. Cowboys and indians, explorers and natives, as you like.
Then there are potential internal conflicts. I've started the Euroship; they might not have political officers to keep them in line, but politics has decreed that each come from a different country, that there are equal numbers of men and women, that minorities are represented… it's just fortunate they didn't insist on a representative population of physically disabled, or a standardise age distribution. Thus, it's not always the best person for the job, but the most correct. The Islamic League ship won't have this problem, but they'll be forced to bring spiritual guides as well as technical, and the various branches will cause tension if not violence, Similarly, the two American ships (governmental and private enterprise) the Pacific (I don't know how the Nippon/Aussi team up will work out) The Chinese, Russian, Latino, India/South Africa/Israel ship; all potential internal conflicts waiting to happen, all for different reasons.
Then, the ships have to return home regularly with the data they've obtained, and 'home' might be less than delighted with the results; more potential problems.
There is also the risk, in early days, that they hit the same planet as one of the other ships; or one where the other has just been. Or even one where the original ship that started the exodus has just been. Probably at a different geographic point, but in any world with global communications this is irrelevant.
Finally there is the problem of the technology itself; this is a mature science, but it wasn't develoed by them. These are all prototype ships, built from blueprints delivered by people who'd been doing this for some time, but had received blueprints…
There are thirty people aboard the Euroship, and I've lightly pencilled in two. Every landfall will introduce dozens of new characters, a tiny fraction of whom will become 'companions' If that's not enough, there are the other ships. And the Earth origin, where the newly introduced technology, particularly the fusion generator, with no preparation time, are unbalancing various economies, particularly the Gulf states (main financers of the Islamic League ship) and the Russian union, both desperate to grab a compensating advance.
There's got to be enough there for conflicts. Missing that, every time you translocate, an equivalent volume of atmosphere will go the other way. This will contain some biological matter (bacteria, viruses) and, since the universe next door is biologically practically identical, this might introduce an organism to which we have no inborn defenses, with risk of plague. I can see the sort of anti genetically modified fanatics trying to stop the launch of the vessels to avoid this risk.
Biohazard sealed suits would be standard wear while on mission; not very romantic, certainly, but safer than red shirts.
1.) Could this be a cold fusion generator? (I know you used waste heat to fill the gas bags, but even a cold fusion generator could produce heat quite easily.)
2.) By "stockage", do you mean it's storage capacity, it's mass, or perhaps its actual size? (sorry, I'm just not familiar with this usage of the word)
It could very well be catalytic fusion, and if that were to be giving appreciable amounts of power it would be as hot as a steam engine 'cold' is relative – it's just not at a hundred million degrees, or so. Plenty of heat to expand gasbags,
'Stockage' is my standard energy storage problem. You can't store electricity. The best you can do is convert it into mechanical energy (pumping water uphill, flywheel) or chemical (battery, fuel cell) I'm proposing storing it in a magnetic field, produced by an enormous current flowing in a superconducting loop.
Sorry I'm a bit slow with my replies; I had a session last night which went on till half past one, so didn't get any typing done.
Hey, I know what I've written is all tell and infodump; the idea is that it be a social project, no? And if anything there is essential to the comprehension of the story, you can rewrite it to fit; I build universes, I'm not so good at peopling them.
Unless you'd like a dragon?
