QUEENSFERRY (Reuters) - The world's richest corporations and finest
minds spend billions trying to solve the problem of carbon emissions,
but three fishing buddies in North Wales believe they have cracked it.

They have developed a box which they say can be fixed underneath a car
in place of the exhaust to trap the greenhouse gases blamed for global
warming -- including carbon dioxide and nitrous oxide -- and emit mostly
water vapor.

The captured gases can be processed to create a biofuel using
genetically modified algae.

Dubbed "Greenbox", the technology developed by organic chemist Derek
Palmer and engineers Ian Houston and John Jones could, they say, be used
for cars, buses, lorries and eventually buildings and heavy industry,
including power plants.

"We've managed to develop a way to successfully capture a majority of
the emissions from the dirtiest motor we could find," Palmer, who has
consulted for organizations including the World Health Organisation and
GlaxoSmithKline, told Reuters.

The three, who stumbled across the idea while experimenting with carbon
dioxide to help boost algae growth for fish farming, have set up a
company called Maes Anturio Limited, which translates from Welsh as
Field Adventure.

With the backing of their local member of parliament they are now
seeking extra risk capital either from government or industry: the only
emissions they are not sure their box can handle are those from aviation.

CAPTURE RATE

Although the box the men currently use for demonstration is about the
size of a bar stool, they say they can build one small enough to replace
a car exhaust that will last for a full tank of petrol.

The crucial aspect of the technology is that the carbon dioxide is
captured and held in a secure state, said Houston. Other carbon capture
technologies are much more cumbersome or energy-intensive, for example
using miles of pipeline to transport the gas.

"The carbon dioxide, held in its safe, inert state, can be handled,
transported and released into a controlled environment with ease and a
minimal amount of energy required," Houston said at a demonstration
using a diesel-powered generator at a certified UK Ministry of
Transportation emissions test centre.

More than 130 tests carried out over two years at several testing
centers have, the three say, yielded a capture rate between 85 and 95
percent. They showed the box to David Hansen, a Labour MP for Delyn,
North Wales, who is now helping them.

"Based on the information, there is a clear reduction in emissions,"
Hansen told Reuters.

"As a result, I'm facilitating meetings with the appropriate UK
government agencies, as we want to ensure that British ownership and
manufacturing is maintained."

The men are also in contact with car-makers Toyota Motor Corp of Japan
and General Motors Corp. of the United States. Houston said they have
also received substantial offers from two unnamed Asian companies.

Both Toyota and General Motors declined to comment.

SECRETS

If the system takes off, drivers with a Greenbox would replace it when
they fill up their cars and it would go to a bioreactor to be emptied.

Through a chemical reaction, the captured gases from the box would be
fed to algae, which would then be crushed to produce a bio-oil. This
extract can be converted to produce a biodiesel almost identical to
normal diesel.

This biodiesel can be fed back into a diesel engine, the emptied
Greenbox can be affixed to the car and the cycle can begin again.

The process also yields methane gas and fertilizer, both of which can be
captured separately. The algae required to capture all of Britain's auto
emissions would take up around 1,000 acres.

The three estimate that 10 facilities could be built across the UK to
handle the carbon dioxide from the nearly 30 million cars on British roads.

The inventors say they have spent nearly 170,000 pounds ($348,500) over
two years developing the "three distinct technologies" involved and are
hoping to secure more funding for health and safety testing.

Not surprisingly, the trio won't show anyone -- not even their wives --
what's inside the box.

After every demonstration they hide its individual components in various
locations across North Wales and the technology is divided into three
parts, with each inventor being custodian of one section.

"Our three minds hold the three keys and we can only unlock it
together," said Houston.
