Just In Time For Christmas, The Driveable Lego Car
An Australian entrepreneur and a Romanian inventor have teamed up to construct an air powered car built completely of Lego bricks (sans tires and wheels) that has proven capable of running at speeds in excess of 10mph.
The car features four interconnected engines and uses a whopping 256 pneumatic pistons. The mechanics would appear to be similar to steam piston engines that this author once worked with, with compressed air taking the place of high pressure steam. Air would flow from a pressurized tank, enter the piston chamber via some sort of valve gear and force the piston through its stroke. No combustion is necessary.
The project is one of those crazy things that can only happen over the internet. The car was originally proposed in an online conversation between two people who were literally half a world away from one another and crowd-funded after forty people responded to a late night proposal on Twitter. The car was built in Romania and then shipped to Australia where it was reassembled and then tested. There are no plans at this time to build another.
