I am again grateful to Dave of Solarventi for this encouraging notion on Hydrogen.
This is a fuel I have some significant faith in, IF it can be produced to a reasonable enviROI.
There is also the small matter of reduction. As water, in the form of vapour, is still a greenhouse gas, I don't want to find we substitute one man-made exhaust pollutant for another, no matter how seemingly benign it may be.
