RE:Time to buy?Westport needs for natural gas to be cheaper than diesel on an energy basis. This was happening in N.America between 2006 when the shale boom started and 2014 when the shale boom was so successful it forced oil prices doiwn. This was when WPT went up to almost 50. While natgas prices were depressed an LNG industry was developed in the US to export the extra natgas overseas where natgas prices were much higher. No cheap natgas anytime soon.
