1st off:
I applaud John's work, regardless of the outcome.
2) To those who put forth the if it was a viable solution, it would have been out there already type of argument:
Prior to toro1 having the desire and the requisite skills/knowledge to put his kit together, no one made a bolt-on supercharger kit specifically designed for the VFR.
The fact that such a kit didn't exist prior to this point did not prove that it wasn't possible, only that someone with the desire and abilities to create one had not yet decided to put one together.
In a similar fashion, the fact that no one has yet used HHO gas production in this particular way, does not make it impossible. It simply means that no one has yet been interested enough to do the work.
That lack of interest may be due to any number of reasons, including economic.
One always has to remember that the matter of scale is always a factor when it comes to the implementation of technology with regard to automotive/motorcycle companies. ROI is always a part of the formula. Witness the demise of our beloved gear-driven cams.
One also has to remember the federal government has a lot to do with the direction and types of R&D in the automotive and oil industries. Tax incentives, research funding and government mandates all play a role.
Remember the formation of the Synthetic Fuels Corporation after the oil crisis of the late '70's and it's subsequent abandonment a mere 5 years later?
That resulted in Exxon abandoning the oil shale project it was working on on Colorado.
On a related note, it is the federal government that has mandated that both industries develop the use of ethanol, even though ethanol is a less efficient fuel, causes a host of longevity issues and ethanol production for fuel in the US has far-reaching agricultural ramifications.
As long as the current method of oil extraction is the most economical, it will be used.
That will change only when oil extracted with that method is no longer available, or another method is more economical.
3) Apart from being a fuel source, oil has many roles in many industries. Moving to an alternative fuel will not eliminate the desire for oil.
Since it is a finite resource, it makes sense from a business standpoint to develop alternative fuel, thus prolonging oil's life span in the other industries.
4) Unfortunately, the old adage of necessity being the mother of invention is true.
Human nature being what it is, the alternative solutions are never ready to implement ahead of time.
There will always be a lag-time when transitioning from one energy source to another.
