The Air Powered Daihatsu Hijet Superleggera. Look at that!
This is by far the scariest car i ever saw in real life. The body are plastic, the crumple zone is made out of calcium (also known as "leg"), the tires comes out of motorcycle, the brakes comes from a mountain bicycle, and the engine is:
That. A Tiny box. The car works by releasing the air from the big 50kg tanks there, and the massive pressure of the tanks will move the gears inside the engine and eventualy, move the car. ookay. As a result, the creator tells me that this thing could do 30mph in a good day, and with 50kg of air tank, it will do 5 miles. They said they're preparing another version of these with 20 air tanks, each weighs 50kg, and could do techincally 100 miles with 1 Ton of air.
And i have a very bad feeling about their second prototype. That's the interior btw. No radio, no Air Conditioner, and could only seats two. It's a manual btw, altough he didn't tell me how the gearbox works or will i be able to control the throttle.
At least it has been done thousands of miles, some say. Altough they didn't let me to drive it. Oh Dear.
Anyway, those photos is from my local Surabaya Motor Show!
There's more cars coming up in several hours, stay tune in my kinja!

That is absolutely terrifying.
I wonder what the MPG equivalents are for the energy necessary to compress the air that fuels it...

From what I've read, compressed air is roughly as efficient as batteries when it comes to storing power - at least in the same ballpark - and because of course compressed air systems have much lower embedded energy costs, they can be more energy efficient overall. Yeah, we're still rubbish at making decent batteries.

I like the way this is held in place.
Edit: Also, this vehicle gives "gas pedal" a whole new meaning.

Wiki says (after doing the conversion myself) that they're sitting around 11-27 W-h/kg. Lithium-Ion batteries are at least 100 w-h/kg.
It doesn't mention anything about storage efficiency, or "how much you can get back for how much energy you put in".A Li-Ion battery is around 50-70%. Depending on how much energy it costs to compress the air (which I can't seem to find anywhere and probably varies greatly) the battery might still be inefficient.
All interesting stuff.

I don't remember specifics, or where I read it, so that's a bit useless :)
I think what I understood was that storage techniques vary a lot, but the efficiencies come from skipping the battery stage. Of course it takes lots of energy to compress air, but that's the whole point: the question is how much of it you get back out. I think you can also do things like running air compressors directly from windmills, which of course skips out another conversion and so is even more efficient.
The big advantage in energy terms, though, is that making batteries is very energy intensive. Compressed air storage systems take a lot less energy to make.
There are other advantages as well, though. You can recharge a compressed air system a lot quicker than a battery.
