I took a hard look at the Honda Civic nat gas model (made here in Indiana).
But the scuttlebut on home compressor units is that they are unreliable (they are certainly expensive too).
But I think the economics are so favorable for the fuel we’ll see a lot of commercial usage.
The original units were. That company went out of business and BRC, a company that had been making commercial sized units bought out the rights to the the Phil unit and now produce it.
