That Sanyo system uses an LPG capable vehicle engine to drive a regular A/C compressor and an alternator to make electricity, a different principle to the units we have been discussing which produce cooling by using the heat from burning the LPG in an absorption heat pump.
I have never come across a small scale CHP (Combined Heat and Power) system that comes close to being cost effective when mains electricity is available, the efficiency of a full size power station is just too good. The exception is when the fuel is free or very low cost, for example bio-gas from landfill or your pig farm effluent.
LPG is cheaper on a per unit basis, it's the reduced efficiency of converting that potential energy content into something useful that kills the costings.
