I see some truth(s) Mostly about Jool. But there are things that can be implemented without major difficulties. The radiation thing would sure be easy to do. Meteor rain maybe too, but honestly I don't know if it would be computationally heavy Impacts would probably be the most requiring thing. And ahout Strawberry said about Moho, it would surely be a thing in the game. I would honestly like to see sandstorms but like t_v said it would boost up the minimal requiriments. Just cover the balloons with gold.

Colonies need more challenges Say, a real-life colony would face the planet's hostile environment. A surface colony on Venus wouldn't exactly be easy to make, as it would have to contend with extreme weather. That's what I suggest. On Duna, you couldn't rely solely on solar panels, since sandstorms could form. On Eve, you have to contend with temperature, pressure and possibly acid storms. A floating colony on Jool (assuming the atmosphere could be chlorine) can withstand unbelievably powerful winds, and an oxidizing atmosphere. Even planets with little or no atmosphere would not be as safe as it would have to deal with radiation and possible asteroid rains (On planets like Dres this would be frequent, since they are in an asteroid belt, or even moons that are inside the rings of some planet). Also on Jool, colonies on its moons would have to face the radiation that Jool itself possesses. A good way to prepare is to predict what might happen, with weather stations being built. Weather balloons could also be launched. This could bring a significantly greater challenge to building colonies.

It would be much better used as extrakerbin life.

They could be similar to Opportunity's, with procedural plates filled with various balloons that can be inflated by stage activation, and deflate after a few seconds on the ground or by stage activation. They could also float.

Just yes It would be great for making videos too

That graph you showed is on Earth, right? In denser atmospheres it can work much better than that, with the same consumption. The efficiency of such engine would be higher in dense atmospheres. If Ovin, for example, has a super dense atmosphere, it could work much better. But one problem is Ovin's very high gravity. Also, let's make some logic: Remember the Stratsenblitz video where he circumnavigated kerbin more than 20 times? It presents the logic that going slower does not increase the range. Higher speeds bring more efficiency. By that logic, this engine could be much more efficient than a propeller electric engine. Maybe I'm just crazy that I like the concept lol Edit: Making the vehicle reach more than 800m/s is unfeasible with this engine. But speeds of at least 300 m/s are already much more than any electric motor

Hmm, it's true. But it would be much cooler to add this electric jet and a reactor part, with the reactor providing power to the engine. It also increases the amount of possible designs, and I LOVE it. Also how would a nuclear reactor fit into a small plane? A good thing would be to add graphrene batteries to this case, Or perhaps Graphene capacitors, which would have much less range but would recharge in instants, which could simply be done with an RTG. About the part of compressing the air, we already know how to compress the air a lot. A hybrid engine can also be made, in which the combustion gases pass through the magnetron too, which would solve this problem. What you think?

A great thing would be to put electric motors in from the beginning of Early Access, we could plan A LOT of missions if they have it, just like with Breaking Ground in KSP1. Another nice thing would be a electric jet engine. Basically, Air from an intake goes past by a powerful magnetron, which heats the air a lot, which generates thrust. It's nothing like an ion engine, in which a noble gas is bombarded with electrons and is directed by electromagnets. This allows it to function in places where "air" isn't really air, like in Eve, or even Jool. Maybe there could be a version like a RAPIER engine, where some gas is injected into the engine so it can run in space (don't know if this really works IRL and it's not tested, so I dont know if it is realistic).

Saying KSP2 shouldn't have a career mode is like being dumb (I'm out of ideas) An unlikely but interesting addition would be something like a concurrent program. Something like another space program, which competes with yours to reach another star, for example. It probably wouldn't be easy to make this work in a good way, but if it did, imagine? Something like NASA vs Roscosmos in the cold war, with cooperative missions being possible between the programs Or in multiplayer mode, your space program Vs your friend's one. Especially the last option, imagine how amazing it would be?

Perhaps it is a good addition to KSP2 as it can be extracted in CO2 rich atmospheres, which means it can be extracted on Duna and Eve! But hey, wait. Why add that, when methane can also be extracted, also being more efficient? Simple. Unlike methane, carbon monoxide can be producted with 100% indigenous materials, whereas CO2 can also be converted into oxygen. This means it would be a pretty much infinite, easily producted fuel. This would dramatically reduce complexity and cost in a colony. NASA has published an article describing CO fuel (just search "Carbon monoxide rocket fuel" and you will find it). Maybe it's 80% useless fuel. Maybe it's a nice addition to KSP2, and maybe they're already including it- but hey, I'd like that fuel in the game.
