Air-powered Lego car can do up to 20 mph Dec. 19 (UPI) -- Steve Sammartino and Raul Oaida have built an air-powered car built from 500,000 pieces of Lego that looks like a Hot Rod. Melbourne entrepreneur Steve Sammartino and Raul Oaida from Romania built the car, part of the Super Awesome Micro Project, in Romania and then shipped it to Australia. The car's engine is made up of four orbital engines with 256 pistons and can propel the car to a top seed of around 20 miles per hour. The car was built using crowd-finding and got in forty Australian donors, who based their decision on a unconventional plan. Super Awesome Micro Project
