The recycling system involves the innovative use of an exchange resin in a resilient foam configuration, which also acts as a cushion. Methane released from the driver (and passenger if present) is avidly scavenged by the cushion and moves by diffusion toward the extraction unit where the free gas is regenerated and fed to the fuel system. This elaborate exchange system eliminated the unpleasant sucking sound at idle that was one main factor in abandoning the suction delivery system in the prototype. The so-called butt-sucker reportedly will be made available as an option for those who prefer the negative pressure ride. Also, unlike the vacuum system, the resin-cushion recovery system (RCRS) is not subject to failure under overweight girl friend.
