"Now that we have surpassed the 1.5 V threshold required for hydrogen fuel production in real world systems, we will identify next steps in terms of scaling up the technology. Following this breakthrough, we will focus our efforts on increasing the hydrogen production efficiencies of these particles by bonding the ideal fuel production catalyst to the low-cost high-voltage solar cell. In order to achieve this, the company is currently exploring two parallel approaches. The first is to identify materials that interface with well-known hydrogen production catalysts, such as the platinum on solar particles, to improve sunlight-to-hydrogen conversion efficiency. The second is to pursue methods that further increase photo voltages of solar particles to greater than
1.7 V that allow integration of cheaper earth abundant catalysts without significant loss in hydrogen production efficiency. We believe this will bring us closer to developing a prototype or pilot."

I take this to indicate that the device is not yet cost effective? I wonder how close it is?
