CNG is also very expensive! I like the idea, but in this area NG has gone up close to 300% in the last ten years. Propaine is cheaper than natural gas here right now. I can't see either as a real permenant alternative.
Hydrogen is the most abundant element int he universe. If you have sunlight silicone and water, you have hydrogen!
See ya

Huh? Silicone? Why do you think you need a rubbery polymer to create Hydrogen?
LOL! Silicone is synthesized from silanes which are silicon + 2 methyl + chlorine.
Did you mean Silicon, an element in and of itself? You don't need sunlight nor silicone rubber nor silicon to have Hydrogen!
Latest NG cost per gallon equivalent to gasoline for Natural gas is $1.26 per gallon reported by Clark Howard, but I haven't looked it up or done the math myself.
Back in '77 I built a 150KW electric generator plant for the chemical company I worked for as a backup. I decided on Natural gas fuel back then since we had it in the plant. We also had large #2 fuel oil storage for our boilers. The main advantage of CNG we discovered was how clean the engine ran. Not only did it never need a tuneup, the engine oil lasted for 2 years before testing out of lubricity spec. Even then it looked like new oil since the carbon was non-existent. CNG engines are very clean and very low maintenance. I believe Propane is similar. We have huge NG supplies in the US to supply our increasing needs for the next 100 years with present known supply.
As for cost, I found this USDoE data at this link:
Colorado Natural Gas
While this government chart clearly shows NG being lower cost than LPG for the same time period, it is not current, and I would not go by this as a valid scientific comparison. I would prefer to compare the $ per million BTU of each, rather than the $ per unit volume.
Today, the cost per million BTU -
LPG approximately $20
NG approximately $10
by today's market
So the cost of NG is about half that of LPG if you use it for energy but both are independently market driven..
PS-
Truth is irrelevant when you have a good ad campaign.
This statement speaks volumes about the character and integrity of the person making it.
Any ad campaign that lacks truth will fail and the effect of that failure will have disastrous repercussions.
Reminds me of a news reporter who believed that he should never let the facts get in the way of his story.
