John from NJ "Your mixing CNG with Propane" CNG where commercially available is selling from $0.75 to $1.60 Per liquefied gallon. At the well head it is currently around 13 Cents per liquefied gallon with the markup coming from pipeline cost and taxes. On the spot market it is right now selling for around $3.85 per thousand liquefied gallons making it so cheap that it make it next to impossible for any other energy source to compete.
With Diesel Off Road diesel With a lower tax rate is selling for around $2.80 to $3.30 per gallon. What's not mentioned is both state and federal taxes on diesel make up over half the cost of the fuel. Many call it the hidden tax because there are few diesel cars on the road so the tax applies mainly to commercial operations. Of course in the end we pay for it highly inflated goods and services.
As for zero Sum Games comments CNG is used to fuel not only internal combustion engines but also Micro Turbines "The worlds most efficient" and fuel cells which will have a big future in transportation. Electrically powered transportation will never dominate our transportation future because of the energy required to build the motors and batteries used require mining of the resources. at a minimum of one ton of rock needing to be processed to create 1 gram of any major mineral your sustainable environmental future is quite a pipe dream
I'm almost a firm believer in not wasting time nor more money on old Technology...Exception making it much more efficient or increasing the value of each dollar spent...One in the same.
As far as the question of Internal-External Combustion Engines or Heat engines..???
If I sat my old Truck out next to our Fire Pit....Started the truck then the fire, I guess I would have an example ??
Of one producing heat and power for equipment; The other producing heat and power being lost into the atmosphere...I shouldn't read shidt like this, because it makes little sense and is just more confusing to an old man such as I....Examples Please..??
