An Ion Motor + A Fusion Plant + A Solar Pump + One big hull and we're ready to go... Hmm... We also need an agricultural section for food etc etc...
Step 1: Ion Motor
Technology exists we just need a enhanced big version of it
---------------------------------------
Smaller engine
Ion propulsion systems are less powerful than conventional chemical rockets but can run for ten times as long using the same mass of propellant. This makes it possible to reach a target with a much smaller engine, reducing overall launch costs dramatically.
SMART 1 is miniscule compared to many spacecraft. It weighs 367 kilograms and measures one metre on all sides, although its solar panels will unfurl to measure 14 metres across.

Step 2: Fusion Plant
The first (prototype) fusion power plant is ready to be constructed...

The debate over whether to build the world's biggest nuclear fusion facility in France or Japan is going critical. The European Union says it could pull out of the international project and build its own, if the project goes to Japan. But the US has firmly backed Japan as its preferred site.
The ITER (International Thermonuclear Experimental Reactor) project aims to lay the groundwork for the eventual use of nuclear fusion as an inexhaustible and environmentally friendly energy source. The French and Japanese sites are the only contenders left from a list that also included sites in Canada and Spain.
The project would heat atoms derived from seawater to millions of degrees, creating a plasma of charged particles. Magnetic fields would contain the plasma and spur the atomic nuclei to fuse. This would generate heat that, if the project worked, would sustain the reaction for about half an hour and release five times the amount of energy that was initially put in.

Solar Pump
I guess the solar pump isnt necessary as we would have a fusion plant...
We would however need a fuel shark (op2) in order to gather hydrogen from planet atmospheres...
----------------------------------------
Earth-based solar pumps can't collect enough energy to turn sunlight into laser beams because clouds and moisture get in the way of the Sun's rays. A space laser wouldn't encounter these problems, and the Japanese team say their system will have a fairly respectable efficiency of around 30 per cent. Some energy will be lost in the conversion from sunlight to laser light, and also as the laser beam travels back to Earth, if it travels through cloudy moist skies. But the researchers say they will position the collection station away from cloudy or polluted areas.

Only a couple of facts
I hope i can buy a space pleasure cruise ticket to the moon when im old
