not sure if you guys have seen this....
my take: if you know anything about the energy density of fuels youll know that compressed at 250 bars natural gas contains less than 1/3 to energy density gas and less than 1/4 the energy density of diesel...
that means gas would have to sell at 5.25 and diesel would have to be selling at 6.75 a gallon for this to even be worthwhile.. and even then at 4$ a gallon of diesel the energy in petroalgae (diesel made from algae) would be more cost effective than nat gas and is a renewable resource...
not sure why the motley fool is pumping this garbage
