propole, no I don't have a website running just yet, there's one on the way.
As for the crash testing, don't believe too much of what they tell you - I studied for both my degrees in Engineering (Chemical Eng and Mechatronic), I know that having the tank secured is important but tank chassis's have to be built for the vehicle they are being fitted to in order for the chassis to operate as it should, chances are that the Ionics chassis are pretty safe but and this is a big but, thatcham approval is a very general approval, note how the Ionics systems are NOT TUV approved, TUV being the world authority in these areas.
Ready built?? Any of the system suppliers on here could have a system ready built for you when desired. So no for anyone thinking I'm just pushing my own systems.
I agree that Ionics systems are reasonably good systems, the marketing does help a bit I suppose, at the end of the day its your own money you are spending, just choose wisely.
