I guess it's a sign of the times that so many people know so little about how diesels operate and what Glow Plugs do? IMO, diesel technology is superior to gasoline tech and last time I checked, diesels were getting 20-30% better MPGs than gas.  But it's been a whole since I checked - On

could this be a scam looking for investors to fill their bank with cash so they can then disappear?  Seems risky when getting involved with the securities organizations around the world.  But once they get the cash they might find their technology isn't as advanced as they say? To me it

I'm trying to figure out this approach. Are they claiming that they get complete combustion at a lower temperature? How would that be beneficial? If less of the fuel's energy is lost as heat, that could increase the efficiency? Lower combustion = lower NO emissions? - Max Charleston
