Awesome Integza

A good knife can be a useful self-defense tool. But if you really want to ward off enemies, adding fire to the equation couldn’t hurt. Actually, getting stabbed by a flaming knife would hurt a lot. Integza shows how he made a knife that shoots flames from tiny holes in a porous metal blade. He theorizes that the tech could be used to improve jet engine efficiency.

We’ve seen a skateboard powered by a pulsejet; now, here’s one that uses a turbine. After explaining how turbine engines work, Integza created a replica of the turbine used by the infamous V-2 rocket. He had the main part fabricated by JLC3DP and then made a set of reduction gears to increase torque. The turbine spins when exposed to high-pressure gas.

After showing off a simple rocket built from a soda bottle, Integza was inspired to make a more powerful see-through rocket. He built its combustion chamber from a glass cylinder with a custom-made metal swirl injector. Along the way, you’ll learn how fuels and oxidizers work and a little about turbochargers and top-fuel dragsters.

After making a bladeless fan that runs on ionic wind, Integza wanted to see if he could harness that electric breeze to create a small jet engine. He used a small transformer to step up the voltage and wired it up to send electrons between a nickel and copper-plated ring. It’s not very powerful, but it’s still incredibly cool.

Dyson’s Supersonic hair dryer pushes more air and dries hair faster than most. Integza figured out a way to use its tiny and powerful motor to create a handheld jet engine. First, he had to use an industrial 3D printer to produce a metal case for his project. Then he injected fuel into its combustion chamber and ignited it.

Those fancy Dyson fans are called “bladeless,” but they really just hide their fan blades in the base. Integza wanted to see if it would be possible to build a fan that actually has no blades. His theory was that he could harness and direct the ionic wind created by high-voltage electricity.
