That's hilarious, I thought you were kidding. I remember an amusing publicity stunt in which a scientist pwned Ralph Nader by declaring that he would eat as much plutonium as Nader would consume caffeine, but this is the first time I've heard of someone actually putting their money where their mouth is.

Course when you really get down to it, if you are going to go through that much trouble to make a table top accelerator, it seems like it would be easier to skip the electrical energy to mechanical energy and mechanical energy to electrostatic potential steps. Seems like charging a capacitor and using some sort of cathode/annode setup..... and that is how the VDG ended up in the museum :)

Agreed, a Cockroft-Walton multiplier should be pretty easy to construct these days with HV components available on eBay. It now occurs to me that it might make sense to ditch the belt and motor in my VDG altogether, and just build a CW multiplier into the acrylic column. Hmm.

That's some pretty impressive kookery, but actually a small VDG can be used to accelerate electrons (and presumably protons as well in the form of H+ ions). See the chapter in C.L. Stong's anthology of Scientific American's The Amateur Scientist columns, beginning on page 344. There are a few copies on Amazon, and there is also a .PDF floating around, along with the 'official' CD-ROM edition which is a pile of proprietary crap.

I keep meaning to try this, if I ever get the mechanical reliability of my own VDG up to par. Right now it will run for about a minute at most before something breaks.

Could you get a perpetual license for all of CS6 for $360? Was the educational discount that good? If so, I can see where some people would be pretty unhappy about it.

IMHO the Creative Cloud package isn't too bad a deal. I mostly use it for Photoshop, but I needed a good video editor the other day and it was nice to be able to run Premiere Pro without jumping through any other hoops.

It also appears that CC apps can coexist on at least two different PCs without any licensing hassles. The DRM is not as unobtrusive as Steam but it is still fundamentally pretty usable, from what I've seen so far.

To play devil's advocate: ubiquitous surveillance as in the examples you bring up would not come with unlimited resources to follow up. The very existence of this capability will force the authorities to focus their efforts on people who actually might be a threat. You know, like people who are actually on terrorism watch lists.
