[QUOTE="dragoner, post: 7564013, member: 6943731"] Eventually, except in the confines of the question, not today, that is the simplest answer. Sure, we will increase power generation, and if we build a smart grid we won't lose 40% of generated power due to Ohm's Law, from pumping power into a hundred year old grid with hundred year old power plants. It's really baby steps to get into space though, the knowing comes from doing, right now, if we built an interplanetary vehicle, it would be very primitive in design, like one of those Duryea cars in comparison to modern ones. That's before any consideration of an interstellar vehicle. Plus the fundamental truth is that if we could create a vehicle where people could live on some thousands of year journey, we could build an O'Neill Cylinder at a Lagrange Point and live there, not needing to make the long journey. Rockets are engines: [url]https://en.wikipedia.org/wiki/Rocket_engine[/url] I'm lucky enough to have a pint or two with propulsion engineers from Armstrong Hall of Aerospace Engineering [url]https://engineering.purdue.edu/Engr/AboutUs/Facilities/ArmstrongHall[/url] Fusion rockets are often a favorite topic, for right now, they are less possible than Fusion Reactors, due to the nominal erosion of the combustion chamber, at least in theory, as one has never been tested. Someday maybe, sure, but not today. [/QUOTE]
