Odd as a cod I'd say
Scenario, I popped down to a local A/C place to get the old merc regassed, a place called PowerBase in Ashford....anyway, got yapping to the lad who runs it, very friendly, just in the middle of moving premises.
He then started telling me about other services he's trying out...
Lo & behold, he says, for £999 we can fit a hydrogen fuel cell(s) to that CDI Merc & you'll save on average 25% fuel costs
The Engineer in me was very sceptical, however he then took me outside to his old 206 peugeot, pulled away the airbox & voila, a small 5" by 5" plate type fuel cell..WTF ?
He fired up the car & you could easily see the water bottle feeding the cell, was causing the cell to bubble like a goodun'....with a hose going into the intake.
Reckons before ( only a 1.4ltr petrol ) would give him about 400mls on a full tank, now reckons he is getting almost 750 ? I wasn't too sure how you'd plumb it into a turbo'd car, as it would have to be pumped in ???
The device draws about 5A & does require replacing eventually, as the stainless catalyst plates actually dissolve ( didn't mention how long a cell lasts ).
Gimmick or true life fuel saver ???
