Yur prolly right again Gregg. I'll have to seek entrepreneur dollars, (i.e. government grant monies funded by the little people that pay taxes) to further investigate the feasibility of using bleed air from either APU's, or DPF's new trucks must have, to boil off and evaporate amonium concentrate refrigerant used to chill a temperature reducing vessel/chamber to form ice used for cooling brakes. Of course the preliminary research invested into this new technology adds nearly 1250 pounds total weight to the average automotive conveyance, but being a completely self contained and hermetically sealed system, lt is deemed safe for use by my close buds, the "Greenies". As a second vehicle for implementation it could be downsized, and as a safety item be mandated for usage on all passenger carrying vehicles. All in the name of saving "Gods Green Earth", and protecting ourselves, from ourselves, you know. Damn, I hate having to work for my nomination. Nobody else does. Rob
