I am very curious about the electricty consumption of that device. AFAIUI,
it is taking gaseous NatGas from the street pipe and the pumping it into a
gas tank that is mastly liquid, o it has to do a lot of compression of the
natgas to get it into the tank.
That compression will cost you a LOT of energy. No free lunch remember.
Same with the MDI/Tata 'air car' too btw.
Compressed Natural Gas doesnt liquify when pumped into a tank.
You have to cryogenically cool it to liquify it.
Liquifies at -170 C.
Should be fun. They do have big tanker ships moving LNG around btw.
Dispensing it at the pump might be interesting. -170C would embrittle the hose
and cause it to crack. Whoops !
Yes , it doesnt work in liqufied form.
Its only used that way for export.
Large ships with special insulated cryo tanks carry the stuff around
the world.
I fail to see why CNG should be treated differently from any other hydrocarbon fuel.The local busses here run on CNG but its simply compressed as a gas
into hi pressure cylinders which are located on the roof of the bus.
There are some cars running around powered by CNG and there is one CNG
filling station near where I live.
Just looks like a normal petrol station with slightly differant
looking pumps.
CNG is a bit of a dilemma for Govts in how do they tax it.
Gasoline and LPG are taxed, but CNG isnt, or not yet anyway.
If you tax it , then the tax will have to apply to all CNG uses, as
you wont be able to stop people filling their cars at home of the gas
pipe.
