This is a 9 minute video of someone talking very slowly about an alloy block with 4 holes in it.

Presumably whatever componants make it a pulse detonation engine are in his other trousers.

It's also not an engine unless you can power something with it. It currently appears to be a device for rapidly burning propane. What's the output? Doesn't seem to be thrust or there would need to be some way of bolting it down.

I want my 9 minutes back.

I was expecting the bolts to come off and find a picture of nobcat inside

Still, Tesla was an almost supernaturally intelligent bloke and I've seen some of his other ideas brought to life on YouTube. This one's quite interesting:

PDEs are usually three dimensional (i.e. conical) and associated with aircraft propulsion. I wonder if there'd be some way of making a three dimensional Tesla Valve, hook it up to a PDE. Warp speed, please!

9 minutes of a smooth box with a spark plug in it.

Some proper window licker comments there, bumming up to Tesla who didn't do anything apart from devise AC and have his name put to the unit of magnetic field strength.

Plus a Tesla is actually a hell of a lot.

Put a magnet of 1 Tesla near your computer and it won't do it a lot of good...

Been a few updates on the channel
Here is the first test run

Igniting propane in a chamber to make a noise like a playing card in a bicycle wheel? I don't get it, or where he's going with it. The absence of Doubting Thomas' in the comments section suggests they are screened out, so he's made an echo chamber too.

Thanks for the update but I find it very hard to get excited by it

Still, my favourite nut job has diverged from 2-stroke engines into building a log cabin with an axe as the only tool so at least this thing is working... it is working isn't it? Hard to tell

<addendum> Sorry, that came over a bit harsh. Thinking about the concept of exploiting resonances rather than trying to dampen them is one of the root functions of the 2-stroke expansion chamber exhaust system so it's good that people are looking a new ways to view the world.

OK, so he's trying to detonate rather than burn fuel to make supersonic pressure pulses which pull moisture ("cold steam") out of the air. Mention of the sun, atmospheric pressure and the "earth battery" suggests he thinks it might reach such a speed as to be self-sustaining, fuel off. He must want to take energy from that cold steam to do some kind of work.
