Without watching the video again, this happenned several years ago, the problem is that the information disappears. Conspiracy. The gas in question is Browns gas or a variation of it. Browns gas generators are available on line. Made in Japan. Browns gas does many things. Some claims seem extraordinary.
But now the reality. It is assumed that if this knowledge was released for automotive use, the oil industry would collapse.
On the contrary, if You and I no longer had to spend $150 a week on gasoline, we would have that money to spend elsewher.
If the oil people didnt have to convert to gasoline, they would be able to make OTHER petrochemical products. Read--Plastic.
Remember the Fiero? Plastic car made by GM. The Saturn also had plastic panels. They couldnt produce enough product because of expense and lack of raw material. They had to divert to fuel production.
The petroleum industry would boom if an alternative , cheap fuel was found. They would divert to other uses. Plastic vehicles, homes, bridges, roads. Think and it can be. Over the years all of these things were developed and cancelled because of cost.
Many more reasons and examples, but I'll let you guys think up more.
