It's not exactly clear yet what the air-powered, Lego car built by Australian entrepreneur Steve Sammartino and a Romanian tech specialist means, if anything, for the future of automobiles and sustainable driving. Likely, its creation was a statement, publicity stunt, and stimulating exercise all wrapped into one.

Requiring over 500,000 Lego pieces and $25,000 in outside funding, the vehicle is slightly smaller than a standard car, with two doors (swinging hinges of Lego pieces), no top, and a hashtag and Raul Oaida's (the Romanian tech) image as the acting rims, the New York Daily News reported.

Most remarkable is the engine, which operates completely on air via 256 rotating pistons, enabling the car to reach a maximum speed of 18 mph, according to the Daily News. That's about as far as I can go explaining the mechanisms of the engine, of which details have been limited. (There are several companies currently exploring a similar principle in actual cars).

Credit for its design goes to Oaida, whom Sammartino met online. The twenty year old is already famous in his home country for designing similarly innovative automobiles, including a jet-powered bicycle.

While Oaida was the project's engineer, Sammartino occupied his usual roles in fund raising and marketing. One tweet from his account generated the funding necessary for the project:

Given Sammartino's previous experience building a Lego-based space shuttle, the project was likely his idea. He gave Oaida full credit for the design and threw 40 Melbourne residents bones for their financial support on his blog (about which he is very serious).

"As readers of my blog will know, I worked on a little side project with Raul Oaida (the tech mind who made it possible) and crowd funded it on twitter with 40 patrons from Melbourne," Sammartino wrote.
