You guys think this could make something like repulsers?

Sure, but you're still going to have to deal with the physics. You can only pulse-repel something that your arms and body would be normally able to push, anyway. Blast a big solid thing weighing a ton or so, and it will knock you back on your butt.

Would this device work in space? And if so, how much less powerful would it be versus an atmosphere?

What color would this engine emit at the point where the exhaust exits?

A very good question, I have brought up that idea in the green lady thread and the thread about Lockheeds fusion project, whith which I see certain similarities to this.

I am now certain that the spaceplane has been conducting fusion experiments in orbit .



Swing and a miss. Nope. It's last long trip was for testing a new type of liquid optics, for satellite-based imagery.

I was curious if it had something to do with that aircraft.

Either way, though, you're going to be leaving a radioactive streak across the countryside, unless the thing is only used in space.


You saved the best for last-



unless the thing is only used in space.


Given the lack of inertia and and the sluggish acceleration of Ion drives and other alternatives, it makes perfect sense.

Do we really need these engines?


I thought we had those crazy chevrons.

Coming soon: spreading radioactive material to a town near you...

What happens when(not if) one of these planes crashes? Is the material fail safe?


Actually, this would help. Deuterium-Tritium reactions like these produce non-radioactive helium and energized or radioactive neutrons. The neutrons are part of the process and are fissible with the Uranium-238. Since there are no conventional explosives involved, no Plutonium and a crash after flying at any cruising speed survivable or comfortable to the average human would not cause the Uranium to impact with itself hard enough, you would get a very minor amount of fallout if any and simply have to recover the Uranium-238 which is fissible but not weapons grade.

The only radioactivity in it is the natural radioactivity of the U-238 which is no worse over short exposure than what we get from the sun and since Deuterium and Tritium do occur naturally in our atmosphere, albeit in small amounts, there would be no significant amount of radioactive material released during flight. This is the future of space travel more than air travel anyway. Realistically speaking, the speeds this engine will be able to attain in atmosphere will likely be quite high once it is perfected but won't have any practical use here because of the high cost of Deuterium and Tritium. It would almost triple airfare prices unless they find a cheaper way to produce it.

It would emit either no visible exhaust or a white contrail of vapor similar in color and thickness to what you see exiting a nuclear plant's stack.

Nothing happens - there are no radioactive materials involved.

Fusion generates neutrons to make heat - while the engine is running these are dangerous - as soon as it stops there are no more neutrons.


Uh, this stuff has plenty of fissioned ex-U238 trailing behind it. It's not going to pass a EPA smog test.

Basically, inertially confined fusion (alone) doesn't work yet. So they're going back to good ol Teller-Ulam and stuffing it with a fat n dirty fissioning tamper.

By the way, this means that even if your tokamak can't get breakeven in fusion power, if you use DT it would be great for precisely making Pu-239 if one were Doctor Evilish and would the IAEA ever know?


So Tom, is Planet Dirt getting fallout exhaust clouds like you'd expect from them damn dirty Romulans? And that's why it's so SCI? Fear of lawsuits from xenoenvironmentalist lichen-huggers?

not if it's fissioned for energy! They're not going to haul really heavy U-238 as inert ballast on an aircraft.

I read something, a couple of months back, about the heavy element doping of the containment vessel.
The fissile material is undergoing fission, so no radioactive daughter products to be ejected.
The process is more like electrons transferring from one atom to another, but its neutrons instead.
There isn't enough mass of fissile material to initiate fission, and there aren't enough neutron from the fusion reaction to start fission. The neutron is absorbed and kicks out a neutron(at a lower energy state) + an ir wavelength photon,


?????

Nuclear energy scales >>>>>> Infrared wavelength photon energy scales

Nuclei excited by strong force interactions make x-rays and gammas, MeV's and GeV's ---- a ONE eV photon is still hard ultraviolet. Infrared is a little wisp fraction of one eV.

An excited nucleus is not going to have significant direct decay modes through a one-million photon process.

| The neutron is absorbed and kicks out a neutron(at a lower energy state) + an ir wavelength photon, that neutron in turn does the same thing, it gets absorbed and kicks out a neutron+ photon and so on until the last neutron is absorbed by the wall of the vessel.

That sounds like bouncing neutrons off beryllium or pure graphite.

This. Also, the liner will be thermally hot as well as radioactively hot, since the daughter products you'll get will be decaying in there. In fact, you MIGHT be able to get a meltdown of the liner. It would sort of depend on how thick it was...




By the way, this means that even if your tokamak can't get breakeven in fusion power, if you use DT it would be great for precisely making Pu-239 if one were Doctor Evilish and would the IAEA ever know?


I think I brought this up on one thread or another and was ignored. It's a great way to start your day with some nutritious Pu239.

This isn't a workable design. It's a bad joke.

hopefully the space EPA don't crack down on the planet dirt folk this time over their engines like they did over the whole save the lichen debecal.

Hey mb or bedlam,

question for you. wouldn't it be better environmentally in the atmosphere to use 511kev to heat up the air inside a engine. and create crazy thrust that way?

I wouldn't think so. The gammas don't have a high enough interaction cross section and you'd lose most of the energy. Basically heavy charged particles deposit their kinetic energy most efficiently into matter, and that's exactly what comes out of fission and why we can put a heat exchanger and turbine generator to make juice.

Gammas are zero-mass uncharged, and mostly interact by intersecting electrons and then the higher Z the target material the better (more packed electrons), but even then it could knock some out and then there are cascades of more x-rays as the electrons re-fill the inner shells so even more penetrating radiation.

If uranium fission made most of its energy in gammas instead of fast charged nuclei, the plants would be barely lukewarm, no efficient generation, but 1000 megawatts of gammas would zap anybody within a pretty nice radius.

so you couldn't use them in some conversion to heat and suddenly expand air making like a Ramjet or something?

There is no way they will build a self contained system.. what would the Gas industry do?? Sue the heck out of Boeing!


Gas industry is dying thanks to renewables and batteries, it's a reserve fuel in the future.

If your talking about avgas which is an oil derivative, I think the military complex would prefer to have carriers (and others) that need refuelling every 10 years and not have a massive risk that the can lose a war by running out of oil!

You lose the war, oil is no use to you anyway!
