Green Technology

Penn State research explores the production of hydrogen from fuel cells using light and solar photosynthesis.  The research efforts are focusing on overcoming technical barriers to efficient hydrogen production, by varying materials light wavelengths, etc.  …

…   “While some researchers have used solar cells to make electricity or use concentrated solar heat to split water, Mallouk's process uses the energy in blue light directly.

So far, it is much less efficient than other solar energy conversion technologies.”   …
