Liquid Nitrogen powered vehicles.

Currently liquid nitrogen sells for about $2 a gallon.
It’s effectively a steam engine but instead of boiling water you boil nitrogen.
Energy comes from a phase change just like liquid water to gas phase water (steam).
There is no combustion. No chemical reaction. Nothing burns.
Very safe. With the proper PSVs on the tank the worse that can happen is liquid nitrogen spills on the ground and it just boils off.
It’s carbon neutral for the climate change people.
In the video below they claim Toyota’s prototype has an 800 mile range and is pretty quick.
What’s the downside? No liquid nitrogen filling stations. Also I have to imagine because the tanks will not be perfectly insulated (nothing is) fuel will be lost through the required PRV just sitting idle. Use it or lose is probably the biggest technological barrier for this fuel source.

How does the nitrogen get in the tank?

$2 now. Wait till the demand goes up.

Lmao. Stupid and inefficient.

Hoses like this I guess.

Those PSVs pop off all day even on the super insulated cryogenic storage tanks. I can't even imagine how fast the liquid N2 would vaporize in a car tank. Use it in a day or lose it

How did it get into the truck?
Eta: ill save you the brain cells. Getting liquid N2 into a tank and keeping it there is a massively energy intensive process.

Wait till that shite leaks in your garage at night. In the morning you open your house door to your garage and enter a nitrogen rich environment. Good times.

nitrogen gasses off at above -320F 
you’ll need a cryo gas tank

Nitrogen tires are the biggest scams at a dealership

Fun fact, you have to blow off the headspace of the holding tank so you can fill from the truck. Holding tanks lose 2% per day, and the energy required to liquefy atmospheric gases is astounding.

And gasoline would be worthless without ICE vehicles. The price would skyrocket

Yeah I said that in the OP.
I just find this interesting.
Toyota is also working on an ICE that uses ammonia. Ammonia is great in terms of emissions, but pretty deadly otherwise.

Is it currently so cheap because companies like Air Products have higher margins on O2, CO2 and Ar?

Also very energy intensive to produce
, with poor energy density.
Expansion engines of any sort require lots of energy input somewhere in the cycle.
Eta: not trying to shite all up in your thread. It frustrates me when "carbon neutral" gets used in such a misleading manner, and i know it's ultra common. Point of use carbon neutrality is universally less efficient and more carbon-polutinf than just burning the hydrocarbons at the point of use. Its always most efficient to use the largest energy input of the cycle at the consumer. You always lose energy in conversions and in this case, you lose a lot.

Filling would be fairly slow 10-20 minutes

What is the cost and energy required to extract Nitrogen from the air and compress it a? How does that cost relate to the cost to produce gasoline? What is the long term impact of emitting Nitrogen ? Yea, I know it makes up 3/4 of the atmosphere , but what’s the impact of long term gross emission ?

I’m taking those questions as rhetorical because they take too much work to answer properly.

I think I'm currently being exposed to about 790,000 parts per million of nitrogen. Should I be worried?
Nitrogen not kept highly compressed and/or extremely cold (e.g. loose in a garage) will very rapidly go from liquid to gas. And i doubt many garages are sealed enough that any plausible amout of escaped nitrogen will bring the garage interior to sufficient nitrogen concentration to asphyxiate you.
