RoseStreet Labs Scientists Discover Carbon-Free Hydrogen Fuel Source Utilizing
Thin Film Solar Cell

PHOENIX, Sept. 14 /PRNewswire/ -- RoseStreet Labs Energy (RSLE) scientists
announced a leap forward in generating hydrogen gas directly from sunlight by
a photoelectrochemical cell (PEC). This hydrogen fuel is generated
spontaneously in a single device without external power and without petroleum
products such as natural gas. Hydrogen gas is a key resource for next
generation hydrogen fueled cars, and also a key component in the renewable
process of harvesting biofuels and biodiesel for replacement of oil based
gasolines and jet fuels.

RSLE's discovery is coupled with RSLE's Full Spectrum photovoltaic development
which is expected to start field trials in late 2010 with +25% efficiencies.
Full Spectrum technology is primarily based on Nitride Thin Film
semiconductors which have excellent robustness to extreme environments
including solar radiation, heat and corrosive environments. RSLE's
photoelectrochemical cell development is targeting the high performance
terrestrial market for renewable energy.

Bob Forcier, CEO of RSLE, stated, "We are excited about this new development
in capturing the full spectrum of the sun for not only instantaneous power
generation, but also for energy storage via liquefied hydrogen or to assist
the emerging biofuel and biodiesel efforts. Although this is a significant
milestone in our scientific research in Nitride Thin Film photovoltaics, it
also represents the opportunity to commercialize this technology to the next
level with RoseStreet's partners."

Wladek Walukiewicz, CTO of RSLE, announced, "I am pleased with the great
strides we have made in this Nitride Thin Film photoelectrochemical cell
technology working with our distributed R&D teams. We are accelerating our
efforts in carbon-free Full Spectrum photovoltaics and photoelectrochemical
cells for the high performance energy market."

RoseStreet Labs Energy, Inc. (RSLE) is a privately held firm headquartered in
Phoenix, Arizona. RSLE is commercializing full spectrum photovoltaic devices
for high performance applications. RoseStreet Labs LLC, the parent company
of RSLE, is a privately held supplier of products and services for the
renewable energy, semiconductor and life science markets.
