Deuterium water is about as present in the oceans as free hydrogen in the atmosphere, which means it will have to be collected from the seas or manufatured; I'm afraid this might add a few trillion to the cost of raw materials.

Not to mention the cost/source of the (presumably) ultrasound energy...

Manufactured; manufaturing is what happens to the press releases.

A neutron nucleated bubble cloud (size ~6.5mm) in C3D6O just prior to implosive collapse. Fast neutron nucleated bubbles in C3D6O grow from ~10nm to ~1mm in acoustic chamber before imploding to produce neutrons and light.

Heavy water only costs about $28 a pound.
