Yes, but.... it's like those cars that run on used french-fry oil. It's really cheap so long as the demand side stays within the existing production quantities. Once the user base increases, however, the demand for used french-fry oil far outstrips the supply, and prices go up.
Same thing here: the companies in question are almost certainly hooked up to natural gas lines, which take care of heating and cooking needs. That's fine, if you're one of a very few who are doing it ... but once you get thousands of users, the supply chain for natural gas turns out to be completely inadequate and, again, demand outstrips supply and costs go up by a lot.
my main interest is seeing this type of technology introduced into transportation.
In addition to natural gas, they can digest liquid fuels and are much more efficient than the internal combusion engine. I want a full sized 4 wheel drive pickup with towing power that gets 30 mpg.
NG is the one energy source that is in a growth period. We have abundant supplies and more coming on line every day, and it is getting cheaper. Moving it to areas that presently do not use it is an issue, but nothing major.
I happen to have NG and would be very interested in this if it met my needs. In the midwest & south there are many NG users. They say they can work off various energy sources,
like I said a lot is to be seen.
