I've made three different attempts at it so far. Seems the system can work, but it's been componet failer that keeps messing things up. Making hydrogen hasn't been as big a problem, as having a system that will deliver constantly, at least in a volumn that makes it worth while. The truck I'm using can only be down for short periods at a time, which also adds to the frustation. Still working on it as time permits. Winter slowdown should provide bigger blocks of time to get more done. Sniper
