Electromagnets can be very powerful. They’ve even been used to get roller coasters and trains rolling and to launch fighter jets. Tom Stanton made a miniature system of homebrew linear synchronous motors which use electromagnetism to propel a small sled and launch various items including a hot dog and a paper airplane.
Awesome Tom Stanton
The motors used in electric-powered bicycles are usually pretty heavy. Engineer Tom Stanton wanted to see if it would be possible to rig up a tiny but strong 1kW motor from a drone to propel a bike. The trick was creating a series of gears and belts to reduce the motor’s high rotational speed while increasing its torque.
Supercapacitors have one big advantage over batteries – they charge much faster. But they also discharge energy more quickly, limiting operating range. This makes them suboptimal for EVs. Engineer Tom Stanton built a supercapacitor pack and drive unit for an E-bike to see just how it stacks up to battery power.
Aerospace engineer Tom Stanton has a thing for flywheels. Here, he first shows us how to build a flywheel that spins smoothly thanks to magnetic levitation, then how that spinning action can be used to generate a small amount of electricity and capture it via copper induction coils.
Engineer Tom Stanton is fascinated by the way in which flywheels can store up energy as they’re spun up to speed. In this clip, he combines a flywheel mechanism with a sturdy aluminum trebuchet, creating a durable machine that can toss a tennis ball at fast as 180 mph.
When we were kids, we had one of those wind-up toys that launched a flying propellor into the air. Aerospace engineer Tom Stanton wanted to see what he could do if he ramped up the energy by spinning up a larger (and more dangerous) version of the propellor flywheel using a motor.
