I came across this site a couple of years ago. Today it seems more relevant now that I'm aware of peak oil.
Here is an excerpt from their site.

BlackLight Power Inc., is the pioneer of technology based on the patented process of releasing chemical energy from hydrogen called the "BlackLight Process." More specifically, energy is released as the electrons of hydrogen atoms are induced by a catalyst to transition to lower-energy levels (i.e. drop to lower base orbits around each atom's nucleus) corresponding to fractional quantum numbers. The lower-energy atomic hydrogen product called "hydrino" reacts with another reactant supplied to the reaction cell to form a hydride ion bound to the other reactant to constitute a novel proprietary compound. As hydrogen atoms are normally found bound together as molecules, molecular hydrogen is dissociated into atomic hydrogen in the cell by a hot metal catalyst, by a glow discharge plasma, or a microwave plasma. A gaseous catalyst is formed from a source of catalyst by the exemplary methods of heating a nonvolatile catalyst such as potassium metal to form atomic potassium catalysts or by ionizing a gas such as helium to form catalyst. The catalyst causes the normal hydrogen atoms to transition to lower-energy states by allowing their electrons to fall to smaller radii around the nucleus with a release of energy that is intermediate between chemical and nuclear energies. The reaction creates or greatly intensifies a plasma (a hot ionized glowing gas). The products are power, plasma, light, and proprietary novel compounds.
Laboratory scale devices demonstrating means of extracting the energy have been operated at the Company and at independent laboratories. Results to date indicate that the process can eventually provide economically competitive products in a wide range of applications including lighting, thermal, electric power generation, and motive power.
The Company's plasma energy cells, even in prototype stage, are frequently operating at power densities rivaling those of internal combustion engines with hundreds of times the energy release as combustion of the hydrogen fuel with room temperature start-up and high-temperature capability, commercially important features. The plasma is permissive of a direct plasma-to-electric conversion technology, as well as the production of electricity by conventional heat engines. The Company currently believes that the scale-up of energy cells to commercial power generation levels will require the application of existing industry knowledge in catalysis and power engineering.
