Initial Data From the Vertigro Field Test Bed Plant Reports Average
Production of 276 Tons of Algae Bio Mass on a Per Acre/Per Year Basis
El Paso Texas: The Vertigro Joint Venture has released initial test
results from its high density bio mass (algae) field test bed plant
located at its research and development facility in El Paso, Texas.

During a 90 day continual production test, algae was being harvested
at an average of one gram (dry weight) per liter. This equates to
algae bio mass production of 276 tons of algae per acre per year.
Achieving the same biomass production rate with an algal species
having 50% lipids (oil) content would therefore deliver approximately
33,000 gallons of algae oil per acre per year.

The primary focus of the 90-day continuous production test was
determining the robustness of the field test bed. Other secondary
tests were also conducted including using different ph levels, C02
levels, fluid temperatures, nutrients, types of algae, and planned
system failures. It is important to note that the system has not been
optimized for production yields or the best selection of algae
species at this time.

The next phase of development will include increasing the number of
bio reactor units from 30 to 100 and then continuing a number of
production tests that may further increase production as well as
initiating various extraction tests. The results released today are
in keeping with data previously announced from the Joint Venture's
laboratory proof of concept test bed. Subsequently, the joint venture
intends to build out a one acre pilot plant with engineer design work
underway at this time.

As a comparative, food crop such as soy bean will typically produce
some 48 gallons oil per acre per year and palm will produce
approximately 630 gallons oil per acre per year. In addition, the
Vertigro Bio Reactor System is a closed loop continuous production
system that uses little water and may be built on non arable lands.

Glen Kertz and Dr. Aga Pinowska, who head the research and
development program, commented "This is a major milestone for us as
we have demonstrated the robustness of the Bio Mass System with
satisfactory production results from a system that has not yet been
optimized for algae production, which will become part of the next
phase of testing". They also noted "We have learned how to produce a
very large algal bio-mass under varying environmental and operating
conditions in our continuous process photo bioreactors. We believe
these initial results are amongst the best achieved to date, and we
are confident we can now increase the productivity."

"We are extremely pleased with the robustness and performance of the
Vertigro technology in sustainably producing commercial quantities of
algae biomass," states Doug Frater, Global Green Solutions CEO. "Over
the coming months we will further optimize the technology and
demonstrate economic algae production for biofuel feedstock purposes."

The Vertigo system may be a solution to the renewable energy sector's
quest to create a clean, green process which uses mainly light, water
and air to create fuel. The Vertigro technology employs a proprietary
highdensity vertical bio-reactor that produces fast growing algae
which may yield large volumes of high-grade algae oil. This oil can
be refined into a cost-effective, non-polluting diesel biofuel, jet
fuel and other applications. The algae derived fuel may be an energy
efficient replacement for fossil fuels and can be used in any diesel
powered vehicle or machinery. In addition, 90% by weight of the algae
is captured carbon dioxide, which is "sequestered" by this process
and so contributes significantly to the reduction of greenhouse
gasses.

Valcent: OTC BB VCPTF (www.valcent.net), together with Global Green
Solutions Inc: OTC BB GGRN (www.globalgreensolutions.comare each 50%
partners in the Vertigro Joint Venture that has developed a pilot
plant in El Paso which became operational in March 2007 and is the
primary research and development site for the Vertigro technology.
Valcent's primary responsibility is research and initial development
with Global Green's responsibilities including final engineering and
commercialization of Vertigro.

I use to have some hope that biodiesel from algae might be a serious
fuel source some day, but after much exploration and doing the math,
it seems to me to be hardly worth the effort. The following is the
new update to my webpage on the biofuel hoax at:

http://home.att.net/~meditation/bio-fuel-hoax.html

"The prospect of growing algae to make biodiesel has more positive
potential than making ethanol from switchgrass, but you are still
stuck with the fact that algae need solar energy to turn carbon
dioxide into fuel. To make biodiesel, algae are used as organic solar
panels which output oil instead of electricity. Research reports brag
that algae can produces 15 times more fuel per acre of land than
growing corn for ethanol, but that still means we would need
approximately 30 million acres of algae ponds in the USA to meet 100%
of our projected automotive fuel usage by the year 2022. That figure
does not include fuel for aircraft and ships. Those algae schemes
that use less land invariably call for feeding algae sugar. The sugar
must be made from corn or other crop, so you are simply trading
ethanol potential to make oil instead of vodka. If you grow
genetically engineered super-algae in open-air ponds, the genetically
modified algae will immediately be carried to ponds, lakes,
reservoirs, and oceans all over the world in the feathers of migrating
birds, with unknown and possibly catastrophic consequences. Using
agricultural waste water is a good idea for producing algae, and algae
may be of use to our society for making small amounts of fuel,
fertilizer, chicken feed, and lubricants. The acreage required to
replace all human oil consumption would obviously be impossible. "

Agricultural "waste" is not really an answer either.

"Using agricultural "waste" to make biofuels has its own problems.
Removing unused portions of plants that are normally plowed under
increases the need for nitrogen fertilizers, which release the most
potent greenhouse gas of all; nitrous oxide. Much of the residual
crop biomass must be returned to the soil to maintain topsoil
integrity, otherwise the rate of topsoil erosion will increase
dramatically. If we mine our topsoil for energy, we may end up
committing slow agricultural suicide like the Mayan Empire. Without
topsoil, the world starves!"

The basis of your argument assumes that biodiesel derived from algae can
only originate in ponds. That is simply not true. Vertical closed-loop
bioreactors such as those from Valcent and others can create lipids from
algae that exceed 50,000 gallons of oil per acre per year, while
sequestering huge amounts of CO2 (removing it from the atmosphere), and
the
byproducts can create animal feedstock or fertilizers, or even
reprocessing
into ethanol. So the land required is miniscule and the only ingredients
are the algae strains, which reproduce 2x per day, water, CO2 and
sunlight.
The water is almost 100% recycled. Maybe rethink your conclusions...
