Thanks for the graphics, Viv. I had no idea those little drill pumps created enough pressure to mold the metal that way. What guage is that steel? No Mike it is a drill stand as an anchor for the arm that pushes down on the plunger in the pump doby at the bottom it is not a "drill pump" that runs o...

This is part of the BCVP project that has been undertaken by the Albion team for the last three years. The problem was how to produce a 180 degre bend in the home workshop cheaply. Nick Ibbitson cracked this one and did it in a style that has to be admired. The high pressure water pump is home made ...

Ok, I can see that sounding certain warnings of common sense does not work with you so I'll shut up. Before I do that, I just to clarify my position -- I am not trying to prove that the E-P engine exists, or has ever existed, or will exist. My knowledge of the matter is inadequate for that and I ha...

"Viv, Graham,"

"I have to respond to what you say to avoid misconceptions."

"Viv, you say, “No sorry old buddy I still think you are wrong, you have not provided a proof by talking about the other engines.â€

No sorry old buddy i still think you are wrong, you have not provided a proof by talking about the other engines. Most of the others we have independant proof in the form of pictures anecdotes etc. But not the EP! all I need is an example of someone who got it to work and i will fall in to line. Ple...

Ok I am going out on the limb for this one, I have not seen a picture or a referance to a working engine. I think it was a doodle on a bit of paper and we have all been interpreting it as a working engine ever since. I don't think it works I think we have all thaught it worked! Don't just flame for ...

Oh no it broke!

Just kidding it was the test kit failed so they had to scrub the test.

Yeah, he sure chose the wrong people as friends didn't he? I think he was even warned by Mossad on numerous occasions not to work with the Iraqi's, and chose to ignore the warnings in pursuit of the money. Hard to believe a man so brilliant could be so foolish. No, he didn't work with Saddam for mo...

you know, you can buy porous stainless steel... it looks fairly normal, but fluid can be pushed through it. I'll ask my buddy for a sample, it's a "sintered powder metallurgy" part used as filtering material and my friend uses it to make air-bearing pucks for very precision flat bearings. I think t...

OK now I hate you! that one works no problem, all we need now is a few K$ to make the dies. But what about the recuperators:-) Yeah, I'm daydreaming about the recuperators now, and also realizing that the ribs are not going to form like that in hydro since the area that would force them radially ou...

Just bell the ends of the intakes (or they won't work)(also looks like they are too long in the rendering), and make as much of the assembly round as you can--and you've got yourself something that should be successful. Here's some flares, Bill. I can't wait to see what it looks like when I make su...

...I read that it takes quite a lot of pressure (1000 psi) to fabricate stuff that way, but ... Check the 304L photo above, they wrote the pressures on them, with varying degrees of success following the die. 11,400psi! A blow-out on a cobbled together rig might just cut you in half! And the gas vo...

Sounds cool! you going to get pictures Mark? as a PS are they still playing with the volatile fuel/air bombs or is the MOAB replacing that one.

Wow I just read the spec on that gun, 2.3 kilometres a second muzzle velocity for a 250Kg projectile!!

Detonation velocity in that MHD PDE paper the other week was 2.5Kms to 3Kms and that was just a pressure wave imagine a shell at that speed!
