Thanks for the encouragement.

Now confident I can do an article for the magazine with some practical experience as opposed to theoretical.
The test unit does look big but the engine, pumps and condensor will be in the engine bay, with the generator in the boot. There is a picture on flickr showing the test generator fitted inside a Mini boot, however also working on a mk4 version that will be easier to service / repair.
Have to say that as an amateur the building of this test rig has been invalueable. Although I am missing out on the fun of driving around it has highlighted a number of minor problems that would have been difficult to resolve if the whole unit was fitted to a vehicle. Still at the stage where there are more problems than answers but the dyno test was a major confidence booster.
Latest problem has been frost protection both for water and fuel, yes wood pellet do freeze together stripping the teeth off the auger drive gear.
The rig has also created interest as a potential 'green' power pack to recharge electric vehicles, not so sure about that one!
