British Inventor Builds Car Engine that Runs on Liquid Air

Here's how it works: when you cool air to -390° F it turns into a liquid. Dearman pours that "liquid air" (liquid oxygen, nitrogen) into a holding tank on-board a vehicle. The liquid is then converted back into a gas via anti-freeze. This expansion (that's wrong it creates a low pressure environment with sucks on the pistons, because when it releases the gas it produces thermal energy cools it down and then it warms up, its implosion tech like hho) and release of air turns a motor that powers the car. so it does require a kind of fuel anti freeze (reagent), its still better than what we have by miles as there are zero emissions allegedly, however i would suspect it emits o2 and h2o with a little tinge of antifreeze, not that u'd recommend drinking it but you could run it back through a condenser unit and a compressor to add it back to your antifreeze tank in a self sustaining loop, but thats just how id do it why waste the energy you could even power dynamos from the central axle with a few tweaks to get all the voltage you would ever need, ;) #peace
