The enemy of my enemy is my friend.
Not quite. If you want to play office politics everyone is you enemy, just play them all off against each other so you don't have to deal with them.
Hmm, my mistake - the ramjet does appear to predate Doctor Bussard considerably - clearly my avionics history is lacking.
On the other hand, Arthur C. Clarke credits "L'Autre Monde: ou les États et Empires de la Lune" (1657) as both being the first example of rocket-powered space flight and for inventing the ramjet. Though I would imagine they probably discussed something similar to a conventional ramjet, fusion having not yet been imagined. (http://en.wikipedia.org/wiki/Ramjet#Cyrano_de_Bergerac)
No, it's been shown that one particular hypothetical design based on one particular set of assumptions would not be viable. Not that the fundamental concept is flawed. There's a post a few pages up that gives more details.
No, I'm pretty sure it's the other way around - there's now a real jet which adopted the name of a theoretical fusion engine that had been designed decades before.
Immortality is only available to individuals who have been permanently sterilized before having children. Your choice - you can strive for immortality personally, or through your children, but not both.
Of course enforcement would be an issue...
Nope. Cosmic radiation is pretty much continuous. What's (relatively) rare is the ridiculous high-energy radiation, such as a single photon carrying mass-energy equivalent to an entire iron atom. Our planet is still presumably getting bombarded by them near constantly, but they're rare enough that it's uncommon for them to hit the few particle detectors we have capable of recording them.
Actually, I believe current research suggests that there may be a link between cosmic rays and cloud formation - it's actually one of the current areas of genuine controversy in climate science. The caveats being:
1) The effect is relatively small - to the point of being virtually invisible until you have modeled the many stronger influences with sufficient precision.
2) It has nothing to do with Global Warming, as the direct measurements of cosmic ray levels have been basically unchanged in recent decades.
Of course, the link between clouds and temperature is even less straightforward. As I recall the research suggests there is only a very small effect on average temperatures, though there is a dramatic effect on the diurnal variation - cloud cover tends to stabilize temperatures, causing slower heating during the day, but also slower cooling at night.
Nah, there needs to be an intelligent species present at both ends of the desired wormhole in order to coordinate its creation. So far no such species exists in the Sol system.
Ah. Of course. Absolutely. Nice catch. I look forward to the day when high-capacity flywheels become cost-competitive with chemical batteries. But I'm not holding my breath.
