I haven't really worked with power transmission, so I don't know how much help i can be with 2(unless you're talking about antennas, in which case you're looking for RemoteTech), but here's some help with 1 and 3. 1 - Like BigD145 said, the labs don't work like that. They transmit science at the rate they generate it when they're focused. When they aren't, they still generate science, but it gets sent back in one big chunk when you focus on the lab again. I think. Edit: Turns out, when you switch to a vessel with a science lab, a message pops up saying how much science was transferred. I did not know that. 3 - There's no specific tree for upgrading parts, they get upgraded at the nodes in the science tree specified in the first post in this thread(there's a picture...not sure if it's up to date). Unfortunately, there's no indication in the science center of which techs upgrade which parts. The computer core and alcubierre drives are upgraded on a per-part basis. You have to have enough science to upgrade them, but then you just right click on them and click on the upgrade button. If you can't access the science center, you're playing in Sandbox, and everything is unlocked and upgraded(again, other than the computer core and warp drive).

Someone correct me if I'm wrong, but I'm pretty sure D-3 makes no sense. Deuterium is Hydrogen-2. If it had an atomic weight of 3, it would either be He-3(with an extra proton), or Tritium, H-3(with an extra neutron). I guess it could be Lithium, too, but I'm pretty sure the atom would be so unstable it basically wouldn't exist. Three protons pushing against each other with no neutrons would probably just fall apart. Judging from the decay rate, you're talking about Tritium, which is *not* known, to my knowledge, as deuterium-3. That'd just be confusing. Then again, I could be wrong about that.

The science lab takes approximately 5 MW to operate, assuming you're only doing research or nuclear fuel reprocessing. In converted terms, each large solar panel, in Kerbin orbit, provides about 12 kW. I think. Probably around there somewhere. So in orbit around Kerbin, you'd need about 417 solar panels -- bear in mind we're talking the big ones here -- to power the science lab. It may seem unrealistic to have the two resources be incompatible, but really, there are only a few scenarios where they would even approach the same orders of magnitude. Are you flying your science lab in a very low orbit around the sun?
