Um, this device can bombard a sample at the bottom of the bottle with electrons. To transform a uranium sample into plutonium, you would need to bombard it with neutrons. Neutrons are a totally different subnuclear particle than an electron. The device needed to produce neutrons is a fission reactor, not an accelerator. Plus, you've got it backwards. Pu-239 is the bomb kind of plutonium; Pu-238 is the kind that just gets hot and is used to power spacecraft out where sunlight is too weak to use solar panels. You need to look up a book on Amazon called The Radioactive Boy Scout, and read the Wikipedia article on David Hahn. Be careful.
