From Wales, a box to make biofuel from car fumes

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.
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.
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.

Exciting if it turns out to be what we hope for!
There are interesting questions raised in response to a similar article on treehugger.com - http://www.treehugger.com/files/2007/07/greenbox_captur.php
A short anecdote told to me by a now-retired engineer from GM: He's now in his 70s, still very active & enjoying life! I won't release his name. He said that when he was young & working for GM, another engineer came up with a design for technology that would severely reduce the emissions from their vehicles. Rather than try to implement the technology on their vehicles, GM paid the engineer quite a bit, essentially bought the design from him & "threw it in the safe for fifty years", to quote the words of my friend. To this day, he's never seen/heard of GM utilizing the technology. This doesn't surprise me because, back then auto emissions weren't under the radar as they are now. However, most companies have proprietary clauses so that they essentially "own" the technology you come up with while working for them. But I suppose he needed compensation for the designs.
So I find it very interesting that your article mentions GM as one of the foreign corporations involved with this Wales-originated invention.
It would be great if others could contribute about the progress of individual nations in terms of this technology.
In the US we certainly get a lot of propaganda & commercials about solutions, that don't actually explain anything. Simply telling us it's a "new solution" isn't good enough. It's a sure less than brilliant idea to mass produce blase advertising that's supposed to increase environmental awareness. We're already aware.
Ok, tag, somebody else go.
