Without going into too much detail I have been thinking about Element 115 a lot lately. To date only about 100 atoms of the stuff has ever been created and it's half-life is milliseconds. It degrades into other elements way to fast to be usable in it's current state. I believe that there is a way to manufacture large stable quantities of Element 115 (Atomic Weight 290) using current technology.
In order to achieve this a lab like Lawrence Livermore (one of the few labs to create the element to date) would need to modify a cyclotron and equip it with a 10 megawatt blue laser and a diffuser lens. Once the modified cyclotron is operational creating the stable version of Element 115 should be simple.
Place a sheet of Plutonium (245) into the cyclotron. This sheet of Plutonium needs to be only a few atoms thick. Then using the Blue Laser and diffuser bath the sheet in high powered Blue UV Light. While bathing the sheet in blue UV light bombard the shit out of it with single molecules of Polonium (209).
This process will cause a large amount of electrons to leave both elements (Plutonium and Polonium) but will fuse the atoms of the two materials together creating a stable Ununpentium sheet with an atomic weight of 290. The blue UV light is the critical part as it causes the new atoms of Element 115 to become stable. Once the sheet of Element 115 is created slowly power down the Blue Laser and the sheet should remain stable with a half-life in excess of 1000 years.
As an added note, it should be possible to harness massive amounts of energy from the creation process as million of electrons will be freed during the process. Additionally, the newly created stable Ununpentium will emit an immense amount of energy that has anti-gravity and non-lethal radioactive properties.
If the newly created Ununpentium is then fashioned into small beads (bearings) and placed en masse inside a spinning ring around a carbon-fiber craft it will make the craft capable of extreme speeds. Navigation could be controlled by controlling the spin of the ring of Ununpentium bearings as well as the location of the bearings in the spinning ring.
