HHO-only Diesel car

If you compress straight Brown's gas (yes 'HHO') then it goes beyond being a risk. Lethal detonation is a certainty.
After what RedDevil said about HHO (see above), it got me thinking: if it's so explosive, even at relatively low compression, wouldn't it be a good fuel for Diesel vehicles (again, only for city use, not for long-distance driving). Like hydrogen, it's a completely clean fuel, so I'd like to use it for this.

At present, it's mostly tested when mixed with a fossil fuel (gasoline or Diesel), but a quick search revealed that some people have indeed used it as a single fuel (not mixed).

Range is going to be far worse than with hydrogen (since that's compressed), and an HHO electrolyser would need to be fed by a battery (and water tank).
So, like battery-electric vehicles, it would be limited to what energy you can store in the batteries, and conversion efficiency is even far worse (less than half of battery-electric vehicles since we'll be using an internal combustion engine). The upside though is that the conversion would not cost much and is easy to do (if you already have a Diesel engine-powered vehicle). Also, this conversion can be done with Diesel-engine vehicles, whereas hydrogen conversions would only be possible with gasoline-powered vehicles.

So, anyone here at ecomodder knows whether this will work, and does anyone also know the correct air/fuel mixture to use for HHO(-only) ?
