In theory all you need for an abundance of any element is other elements as stock, a particle accelerator, energy, and time.

In practice, we'd need the price and size of particle accelerators to go way down, the price of energy to go way down, and the time required to go way down before it would make a difference.

Then again... "Anything that is theoretically possible will be achieved in practice, no matter what the technical difficulties are, if it is desired greatly enough." -- Arthur C. Clarke.
