Kirk Sorensen Thorium, an alternative nuclear fuel
Motherboard TV: The Thorium Dream
This is a great documentary on the element radioactive Thorium. It was set aside in the early nuclear research days in order to produce uranium and plutonium for weapons. I highly recommend you give it a watch and research this element and the new research on the subject.

In our case, it was the latter. While the idea of building small, thorium-based nuclear reactors – thought to be dramatically safer, cheaper, cleaner and terror-proof than our current catalog of reactors – can be shooed away as fringe by some, the germ of the idea began in the U.S. government’s major atomic lab, at Oak Ridge, Tennessee, in the 1960s, only to be left by the wayside as the American nuclear industry plowed ahead with its development of the light water reactors and the uranium fuel cycle. It’s only in the past half-decade that the idea has picked up steam again on the Internet, thanks to enterprising enthusiasts who have chronicled the early experiments, distributed documents, and posted YouTube videos. But if thorium’s second life on the Internet has grown the flock of adherents exponentially, it’s also pulled in more than a few people whose nuclear expertise doesn’t extend far past Wikipedia, adding a sheen of hype to the proceedings.
Still, the idea has legs, if new research programs by India and China are any indication. The former has just announced a prototype thorium-based advanced heavy water reactor, while the latter is researching a liquid fuel reactor based on the 1960s design. In the U.S., the race is being advanced not by the government but by some of the central movers and shakers of the Internet movement.

Is Thorium the Biggest Energy Breakthrough Since Fire? Possibly. - Forbes
For the past several months, a friend of mine has been telling me about the potentially game-changing implications of an obscure (at least to me) metal named Thorium after the Norse god of thunder, Thor.
It seems he is not the only person who believes thorium, a naturally-occurring, slightly radioactive metal discovered in 1828 by the Swedish chemist Jons Jakob Berzelius, could provide the world with an ultra-safe, ultra-cheap source of nuclear power.
Last week, scores of thorium boosters gathered in the United Kingdom to launch a new advocacy organizing, the Weinberg Foundation, which plans to push the promise of thorium nuclear energy into the mainstream political discussion of clean energy and climate change. The message they’re sending is that thorium is the anti-dote to the world’s most pressing energy and environmental challenges.
So what is the big deal about thorium? In 2006, writing in the magazine Cosmos, Tim Dean summarized perhaps the most optimistic scenario for what a Thorium-powered nuclear world would be like:
What if we could build a nuclear reactor that offered no possibility of a meltdown, generated its power inexpensively, created no weapons-grade by-products, and burnt up existing high-level waste as well as old nuclear weapon stockpiles? And what if the waste produced by such a reactor was radioactive for a mere few hundred years rather than tens of thousands? It may sound too good to be true, but such a reactor is indeed possible, and a number of teams around the world are now working to make it a reality. What makes this incredible reactor so different is its fuel source: thorium.
Thorium as the future of nuclear power?
Interesting article over on Wired about Kirk Sorensen and the community served by his Energy From Thoriumblog. To hear these people tell it, thorium fission in fluid fuel reactors offers an idyllic vision of a boundless-energy-from-the-atom type future no one has really believed in since the early 50s. Thorium, reportedly, is abundant, safe, highly efficient as a nuclear fuel, and produces waste that is radioactive only for a few hundred years instead of tens of thousands.
Definitely read the full article on wired about this possible nuclear full that is abundant and cleaner than the ones in use now and also the band of scientists pushing this cleaner fuel named after the norse god of thunder.
