An Australian man has announced he will attempt to break the world record for the fastest-powered street luge.
Street luge sees large skateboards ridden feet-first on public roads.
However, Daz Fellows' attempt will be jet-powered, with two mini-jet turbines strapped to his luge.
He hopes to reach a top speed of 500km (311 miles) an hour in 2015, and has released footage of his preparations so far.
