  • hot dewar

    I have been thinking why not have a dewar mounted in the car just a small one one or 2 gallon add a tube and build it to hold 5000 psi. now you would just fill it at a lng station than have hot heat transfer fluid flow from the motor to the tube in or around the lng and it would boil and expand to 3600 psi and pass through a check valve to the cng tanks. this way you would be able to utilize the lng stations and it would also add a tiny bit of storage. any reason this would not work that anyone can see if you had big tanks you could just cycle it several times and get a full fill.
