I assume it runs on compressed air, is slow and can't go far. It was funny to me that they article explains that the owner raised money to pay Romanians to build it for him and then later takes a tone of complaining about auto manufacturers closing local operations.

Haha. I'm glad I'm not the only who did a double take when the Melbourne man, who we were led to believe completed the project, simply asked people for money and then hired a teen in Eastern Europe with peanuts to build the thing. All the while talking about the ills of out-sourcing.

Fantastic project, but what a strange, article.

There are actually production compressed air cars built by Tata Motors, MDI, and others.

I believe it means that it "runs on compressed air".

Compressed air is a means of storing energy, since you can tap that energy by opening the valve. It's not actually that misleading; gasoline is also a means of storing energy and we say in everyday speech that those cars "run on gasoline".

But it's not an energy breakthrough over an electric cars, you still have to put in energy to compress the air, just as you have to charge the battery of an electric car.

Lego has always had 'pneumatic' pistons and valves. I would assume they have developed a way to use a large array of these to provide the power.
