[@flickthenick]

Yup and how much energy is lost at every stage I wonder? efficiency into thin air!

[@alveolate]

agreed... if your power source is a fundamentally different process from other drivetrains... why is it necessary to still use pistons? aren't there better ways to use pressurised air to convert its forces into turning momentum? i feel like the tech is extremely far from the level of optimisations that ICE is at, and perhaps with enough engineers spending brain power working out its kinks we could get something far more efficient than what we saw in this video. the question is: will the arduous process be worth it?

[@puffinjuice]

Combustion is very complicated as well. There is so much support equipment to make a combustion engine run.

[@erykczajkowski8226]

But how cheap is the equipment to pressurize air, you can do it in your garage. You don't need to move the air around. And the vehicle should be WAY cheaper than even gasoline one, let alone electric.

[@ravenmad9225]

The recharge time is the big advantage. Even EV's are electricity to battery,back to electricity.

Liquified air can improve the energy density problem

[@hamjudo]

Compressed air powered mining equipment made a lot of sense back before lithium ion batteries. They were also quite popular for vehicles that were designed to be used indoors. They were particularly well suited for use in hot environments with low air quality because the engine releases cool clean air in normal operation. They didn't need separate systems for cooling and breathing air. They also wouldn't set off explosive atmospheres in a mine. In fact, they could be built without any electronic or even electrical equipment at all. They also made sense where cleanliness was important. For example, the golf cart like vehicles used inside airports and factories. The limited range wasn't a problem, because those environments typically already had multiple high pressure air connections for pneumatic tools and refilling the tank was so fast. Compressed air powered vehicles have been around for so many decades. Yet they never sold well for use outdoors. They couldn't compete with internal combustion engines where exhaust could be tolerated. They can't compete with electric vehicles, now that we have good batteries.

The 'revolutionary' air engine

[@DozenDeuce]

He did a better job in this single video, than a decade of automotive “journalism”. For those of us that were following the automotive industry during the late 90’s - late 00’s, air engines were a “clickbait” article of the time. It went viral among magazine editors because it was something they could easily slap on a cover, repeat the outlandish claims of the company, then sell a TON of magazines. He’s merely repeating some of the hyperbolic marketing claims of that time and seeing if they hold up to scrutiny…then showing why they don’t. Good update on this blast from the past

[@ChadKovac]

click bait garbage the air is compressed

[@lephtovermeet]

Compressed air isn't an energy source - it's a battery, and a relatively low energy density battery at that. 23% efficiency from plug to wheels isn't that far off from IC engines. So what's the trade-off then to a typical battery operated vehicle? Well, compressed air vehicle theoretically don't need rare earth minerals and are highly recyclable. Otherwise... I'm not sure. They'll have way more moving parts with life cycles due to wear and tear, and the fact that only a tiny prototype has been proven rather than retrofitting a small car shows there's obviously limits to the performance. In a perfect world where we all drive super light smaller vehicles, this might be a viable option that's actually greener. In fhe real world where uneducated emotional consumers demand 5000lb SUVs, infinite torque, and 0-60 in 3 seconds, batteries seem to make more sense, environmental impact be damned.

[@drgyt2469]

He stated the efficiency was driven up to 90% of a Li-Ion Battery.

[@puffinjuice]

Sounds like car manufacturers should be into this if they can make money from selling parts.

[@johncochran8497]

About the only advantage I can see is that it doesn't degrade with time like batteries do. But there's so many inefficiencies in the overall system. 1. When you compress air, it gets hot. That heat is then dissipated over time. So, we lose energy. 2. When you reduce the pressure, it gets cold. I noticed in one of the diagrams that they add heat. Where does that heat come from? Again, we have an energy loss. I'm rather surprised that they managed to get 23% from source to wheels. Honestly, I would have expected lower. And I *really* don't like unmaintained high pressure containers near my fragile body. A general rule of thumb is that if you have some stored energy that can be released in an uncontrolled manner, it can do "bad things". The more rapid and uncontrolled that release is, the more damage it can do. That damage may include killing those people nearby when the energy is released. See kzbin.info/www/bejne/ioumfXmPZdyVbc0

[@mikemotorbike4283]

In a one ton missile called a car, you sit on a gas tank and go 100 km/h mere feet from oncoming cars - just like jousting. You hurl yourself up and suspended unnaturally in the firmament on an enormous pendulous fuselage... straddle tons of explosive jet fuel sloshing under great pressure between your legs, shall I go on?

[@vibs1614]

Old fashioned double expansion steam engine running on air. Still seems fun. Just install a boiler and you've got something.

[@RussellBeattie]

I'm sure they've thought of recharging EV batteries instead of using the engine to power the wheels directly. It seems to make sense - especially with the 90 second refill time. Rough calculations: The Mini Cooper Electric has a 28 kWh battery and gets about 180 km of range. That's 6.4 km per kWh. If the compressed air engine could work well enough so that a tank of air could be converted into 4 kWh of electric power, that would be an additional 25 km of range per air fill up, (assuming the air engine doesn't add any weight). A potential additional 14% range isn't horrible. That said, the added complexity and infrastructure doesn't make any sort of economic sense, so never mind.

[@Patiboke]

Great stuff! Limited range but lightning fast charging. Today there are diesel and gasoline ICE engines and EVs on the road, so it wouldn't be a problem if the future was a mix of EVs and air cars. The latter would be nice for petrolheads who prefer a roaring engine in their car.

[@hamzaterzi8801]

Air must be stored at high pressure for high ranges. To do this, you need carbon fiber tanks. Carbon fiber begins to crack under constant pressure changes (remember the Titanic submarine disaster). Installing high-pressure tanks on civilian vehicles is extremely dangerous. They explode instantly and you don't have time to escape. Pressurized tanks don't give you a chance like a lithium ion battery.

[@ravenmad9225]

Carbon fibre is good under tension,no so good under compression.

I wonder why the picked such a small form factor. their storage tank's energy density should go up the more they scale up the car, thanks to the square cubed law. I'm guessing because they could never be energy dense enough to reach any acceptable range at highway speeds. They could have focused on last mile delivery. Larger vehicles and lower speeds!

Dieser Prozess liefert zudem auch etwas Konstruktionsenergie für das System.
