Centrifuge May Be Superseded by Laser Enrichment

An anonymous reader writes "Australian scientists have discovered, after a decade of tests, a new way to enrich uranium for use in power plants." From the article: "There are at present only two methods for sifting uranium atoms, or isotopes, to create the right mix. One, called diffusion, involves forcing uranium through filters. Being lighter, U-235 passes through more easily and is thus separated from its heavier counterpart. The second method, widely adopted in the 1970s, uses centrifuges to spin the heavier and lighter atoms apart. Both, said Dr Goldsworthy, are 'very crude. You have to repeat the process over and over,' consuming enormous amounts of electricity. The spinning method requires 'thousands and thousands of centrifuges'."

Fuel cells will do nothing about the demand for power stations. Anyways, this makes fuel for nuclear plants even cheaper, and it's already a 'negligable' cost for the operation of a plant.

I say we build so many nuke plants in 'trustworthy'(IE already nuclear) countries that we're buying all the fuel just to feed all the darn things. ;)

Realistically, it's going to be impossible to prevent any country that wants nuclear weapons from getting them. I'm kinda suprised that we've done as well as we have, as all it takes is a country going 'screw you' and building the stuff themselves. We know it can be done with cutting edge 1940's level technology, and it's been over 60 years. Even countries like Iran have reached the point where they can do it with domestic industry if they truly wanted to.
