Also, this is a continuation of research into photoelectrolysis, which was first demonstrated by Fujishima and Honda in 1970. Among the problems needing solving is that once you immerse your photocatalyst in water to do its job, it tends to degrade / corrode. The current goal is to hit the 10% efficiency mark and be able to maintain that for an acceptable cell lifetime. See also nanoptek.com and hydrogensolar.com.
