The key was to use bacteriorhodopsin, a protein found in ancient desert microorganisms, and combine it with semiconducting titanium dioxide nano-particles. Splitting the water molecules by exposing titanium dioxide nanoparticles to bright […]

The inventor, Erik Koepf, has designed a reactor that works at ultra-high temperatures and that uses zinc oxide and water to produce hydrogen at a potentially industrial scale without reforming fossil fuels, as it’s done in the industry […]
