American inventor Robert Maddox has been obsessed with pulsejets for over three decades and has built many vehicles powered by the technology, including kerosene-powered skateboards, bikes and Santa’s sled (unveiled 2022).
The sled’s top speed has yet to be confirmed but Maddox’s Beast is able to reach 90mph, all propelled by this special type of jet engine where combustion occurs in pulses, with few or no moving parts.
Maddox (436k YouTube followers) worked as a woodworker and fine artist prior to building the world’s biggest pulsejets.
