Completely off topic I know, but see if you can get your head around this new invention.

It's gonna revolutionise the world of transport and mechanics

"The IVT dates back to before the 1930s..."

Personally, my favorite are Cone CVT's.

Yes but this is purely gear based system. Not restricted by torque as are V-belt type or cone based vari-drives.

The V-belt might be fine for scooters and small vehicles but try putting a belt system on a 50 ton earth mover.

What makes it amazing is the engine can still turn along with all the gears spinning, but the output shaft is stationery, with no clutch!

That Ozzie guy who invented it is one clever dude.

I'm impressed. Very impressed. But there are a few questions as to how is the lower / stator shaft driven.
Never the less impressive.

Early days yet, but if that guy can perfect this machine, he is gonna be mega wealthy.

I think both shafts are driven by electric motors controlled from the white box with 2 knobs on.

I wonder how it will perform under load?

Can I have one for my Corvette?

Would probably work great with a turbine engine. Great amounts of torque operating at peak
efficiency.
