Wood Gas Cars.If Climate change were real and the IPCC were truly about saving the world then maybe they would grab something that works and make it better.
Wood gas works. Its old technology. Its zero carbon. Its free fuel in some cases, cheap fuel in the city. It can be improved.
Its worked before: WW2
It works now: http://www.youtube.com/watch?v=rHjUJPeUh7A
Its loose in Australia: http://www.gasificationaustralia.com/

There is a hundred video's on youtube alone.
So why is this an ignored solution? Why has it not been optimised using all the resources of government and a thousand universities?
The answer is when they say their pulling out all the stops, trying everything, doing whatever is possible! Their not quite lying but its close! They can't even know that they are wrong.
Governments try to pick winners but the process automatically excludes those that don't call for help or subsidies. This technology needs no subsidies. That makes them invisible to government. Also because those that are invisible to government compete with those getting the subsidies the solutions that work become blocked by the ones that don't quite work. We get technology that needs government help and subsidies and thus can never truly be THE Solution.
So how do you optimise and improve such a technology.
- Hybridise for city use: Add 40 km of lithium batteries, that's not expensive or heavy. Add all electric drive and regenerative breaking.
- Add an optimised 1/4 size gasifier and filter with a small motor optimized to charge as you go. Use an automated blow torch ignition system for the pyrolysis system and computer control. Design the car around the gasifier with a rear engine, gasifier and filter. A rear camera to eliminate the blind spot. Put a baggage compartment in the front.
- I would try a fluidised bed sand filter on the hot gases. In a fluidised bed filter gas flows up through sand. The hot sand catches and cracks tars and ash into light combustibles. The sand also flows and can be made to flow past a heat exchanger to dissipate heat.
- Some WW2 models used water spray filters to wash and cool the gas. That also converts some of the carbon monoxide, the main fuel in wood gas, into hydrogen.
- For optimal no fuss shop bought fuel. Pre pack the fuel in cylindrical pucks made of blocks cut to size and glued with proper spacing between two paper sheets with a sheet around the edge. Add a paper handle. Make each puck under 6 kg. At the petrol station converted to a multi-fuel depot add a raised platform, steps and a remote locked cage of fuel pucks.
- Invent a briquette machine that converts straw into pellets so it can run on grass in the plains and the savannah.
- I would also add a HHO system: an electrolysis cell making mixed oxygen and hydrogen. The hydrogen would bias the flame speed and timing back to normal allowing smaller engines. CO burns slower that petrol; hydrogen burns faster than petrol. The two should balance.
The first priority is the hybrid and the compact optimised power-plant. Everything else will follow as the technology optimises.
I don't think governments can do this. I don't think they can even see real solutions. What's best for the voters is not best for the bureaucrats. Solve a real problem and you kill off a bureaucrats job.
The Earth First greens will automatically oppose this. To them Wood means the evils of forestry. Sustainable human intervention in nature is inconceivable. They will scream 'deforestation'! We must safe guard against that in some third world counties and government run forests, because they are the remaining commons on land. The "Tragedy of the commons" can only happen with government land, tribal lands and the seas. Private lands are not commons.
I don't think Anthropogenic Greenhouse effect is having any catastrophic effects on humanity or the biosphere. Change happens in all ecosystems and climate change is normal.
However Peak Oil is real and solutions are needed. Wood gas as it is currently configured is a good fuel for those in naturally wooded country side. It can be free as the above sites show.
It requires skill; see the planet mechanics get it wrong.
[I think there may be an element of intentionality in National Geographic's talent for botching green solutions and geo-engineering. ]
It can provide stationary power.
Can this be used on every car and tractor in the world? No but this will work where electric vehicles fail. Optimised it will put a big dent in any peak oil problems.
Here are some Swedes having a go in 1942. Full factory production.
(If someone can do subtitles that would be nice. One American wood gas enthusiast caries a small electric chainsaw in his car. I bet these swedes wish they had one.)
