QuantumSphere's catalytic nanoparticle coatings have 1,000 times the surface area of traditional materials, which means that more catalytic action can be housed in the same space. It's the the highly reactive nature of the coatings that allows cheap home electrolysis, also boding well for replacing precious metals like platinum in fuel cells with a coated piece of stainless steel. QuantumSphere's president Kevin Maloney claims that his company's technology makes electrolysers so efficient that they can supply hydrogen on demand while driving. The technology will roll out later this year in a battery that uses a coated cathode for a five-fold increase in energy density, which translates into a 320-percent power gain over alkaline cells. If things go QuantumSphere's way, we won't be paying $100,000 for the Tesla Roadster in a few years, and it will have an even better range than already promised.
