Free energy documentary - a whole 1 hour 50 minutes' worth.

I have to admit, if I had a bit of spare cash, I'd be tempted to convert a cheap 125 to a GEET engine, if I could. Just to see if it worked, like.

I believe it's great if you want to get 300% better fuel efficency from your petrol - at idle.

Couldn't find the link I was looking for, so here's a couple of others from google instead:
Pistonheads: https://www.pistonheads.com/gassing/topic.asp?h=0&f=23&t=264018

Hah. Fair enough - I didn't know that. I wasn't into the whole idea of it supposedly generating plasma, but the idea of preheated fuel vapour seemed like it might be a valid one.

I guess that proves my theory that inebriation + 'documentaries' found on youtube are a bad combination

Ah, afraid I didn't watch it.

And indeed; I view youtube as a source akin to a drunk bum in a cheap pub.

Sure, they might be right; but it's pretty likely they're spouting nonsense with an agenda of supporting their own warped theories; so some serious background checking of their claims before any kind of belief is instilled.
