This technology will only grow and grow rapidly. If they can control the grain structure and molecular bond arrangement of steel. They will be printing hardened steel. That could eliminate CNC machining and create a whole new industry.

Fivedollar saw a 3-D printer demonstrated last February, did some homework, and purchased stock in several companies that directly or indirectly are involved in this technology. Such printers utilize a variety of materials, not just paper. When the price drops to the point of mass-market appeal, it will be interesting to see what develops. It could be the biggest thing since the tablet PC/iPad or just a gee-whiz, nerd gizmo. Caution: I am not recommending that you guys go out and invest in these companies. Some of them are trading at quite a premium to their sales. Do your homework. In my case, I jumped in, but only with very small positions.

that's good looking. Technology makes the world go round

mmmm, what if we used an electron beam melting 3d printer using titanium powder instead of plastic. From wiki: "Electron beam melting (EBM) is a similar type of additive manufacturing technology for metal parts (e.g. titanium alloys). EBM manufactures parts by melting metal powder layer by layer with an electron beam in a high vacuum. Unlike metal sintering techniques that operate below melting point, EBM parts are fully dense, void-free, and very strong." NEMO already has made a full(mostlly) titanium .308 you can see here so there's the pattern.

mine is going to be rechargeable! lol

agreed. but who said the government was concerned with efficiency? ;)

When I print out my Liberator, it's going to be neon pink! :D

I see what you're saying. check out my comment above on the scientist.

I decided to look up the main "scientist" quoted in the History Channel piece. Here's what I found (but I'm not a scientist)

However, I know enough to not buy into Hollow Earth

He's got a good point. I'm no scientist but as a musician, I know that some things resonate better than others, although pretty much everything has a harmonic resonance.

The harmonics are heavily damped by earth material, the plates themselves. They are poor resonators.
ionospheric disturbance would have to be acoustical or electromagnetic. Neither are very plausible, due to R squared losses, not good transmission medium, etc. again, the science husband talking, not me.

When you consider opera singers have caused glasses to shatter just by holding the right note for long enough, I think it's possible for such things to happen. It comes down to acoustics.

somehow you got your point back. hmm

I do not see how energizing the ionosphere can effect the movement of tectonic plates with any sort of energy efficiency. Energy involved in an earthquake say mag 6, is the equivalent of say a 15 MT warhead-100x larger than the bomb dropped on Hiroshima. Hugely inefficient energy transfer from the ionosphere to that -says the physicist husband :)

who dinged you?

well, the whole concept is brilliant

Mine will be F Bloomberg, F Feinstein, F Clinton, F McCain....oh! and F Axelrod....and Maybe F. Shotgun Biden too

One of my favourite 'conspiracy theory government weapons' is the HAARP project. Is it the real life version of project X, or worse? :) http://www.youtube.com/watch?v=foLDKQ00X...
