Store Your Data...For a BILLION YEARS!

Now we're talkin'; store those LOST episodes and family photos for a b-b-billion years.

So now we just need to encapsulate all our civilizations' combined knowledge in a vault somewhere with some self-replicating robot maintenance staff who can also train the sentient beings 1 gigayear hence how to read the darn stuff.

I like the comment about not buying it now because next year they'll come out with TWO billion year storage times.

This post is sort of a collection of alternative fusion techniques (vs. tokamak) . I'll add more as I find them.

Inertial Electrostatic Confinement (IEC) reactors - aka "fusors"
The primary researchers as of late have been Robert Bussard (deceased) and George Miley. I met George at a Lockheed colloquium at the Advanced Technology Center in Palo Alto. He was trying to pitch a modified IEC that would basically have holes poked in it to create a thruster. I think his hope was that Lockheed (et al) would fund him, and then he would eventually get them to realize that, oh, by the way, if this is scaled up it's a fusion reactor! He recommended p-B11 as the fuel, because it tends to be aneutronic.


Levitated Dipole Experiment, (LDX) - MIT project that uses large suspended electromagnets.


Magnetized Target Fusion (MTF):
Saw this in the latest issue of Popular Science.
The company profiled in the article is General Fusion in Canada, led by Michael Laberge.

On Plasma Propulsion

It turns out that the plasma cannon we were envisioning at our last meeting is pretty similar to a VASIMIR engine - notice the use of radio waves (similar to microwaves) to excite the plasma:

General definition of plasma propulsion engine:

Also, here are is an excellent paper on plasma propulsion - it has some other interesting ideas like using the magnetosphere for propulsion, and creating a mini-magnetosphere on spacecraft to protect from radiatio/cosmic rays, etc:

And then there's this recent story that's been going around, which Travis pointed out: http://www.livescience.com/technology/080612-plasma-saucer.html

Also, here is an interesting site about using LTA (Lighter Than Air) technology to get to orbit, using a three step approach - A robust V-shaped wing craft to get to a floating station at 140k ft, where a lighter and more delicate (and streamlined) V-shaped wing craft with ion engines to slowly get to orbit in 5 days. It's a little hard to glean too much from their website, I had to buy their book "Floating to Orbit" to figure out what they were really up to:

Another Lifter Link / Plasmoid Containment Idea

Lifter Link
This one's been around for a while too:
Amercian Antigravity

And hey, right at the top, there's a link to Bob Bussard's last lecture about fusors. It's all interconnected man...

Plasmoid Containment Idea
Have an idea regarding the microwave plasma experiment - possibly contain the plasma with an inverted lifter where the sides form a three-sided pyramid. Where the three planes of air currents converge, at the apex of the pyrimid, is where I imagine the plasmoid being contained. Another benefit is that the noxious Nitrogen Dioxide (NO2) from the plasmoid might combine with the lifter's ozone (O3) to produce not-so-bad nitrate (NO3) and good ol' O2.

Next meeting changed to Thursday May 29th

Since this Friday was short notice, AND is the kickoff to the Memorial Day weekend, how 'bout we shoot for the following week? Also, since Friday's might be more of a relaxation type of day, how about Thursday night, May 29th?

Next Meeting This Friday?

How about if we meet this Friday, 5-22-08? My house?

Would you prefer an evite as done previously, or is a posting like this sufficient?
