Is it safe to transport liquid nitrogen in the frunk? (In a dewar of course, not just filling up the frunk directly with LN2 ) The liquid nitrogen dewar would be slowly leaking and be a constant source of gaseous nitrogen (by design). Will this be safe to do so in the frunk for an extended period of time? Specifically: a) Will the gas leak out of the frunk to the OUTSIDE of the car, instead of into the cabin -and- b) Will it actually leak OUT instead of just pressurizing the frunk? (Can't imagine it being airtight, but just in case).
