Nuclear energy has been around for decades, but its safety and the safety of its radioactive waste have always been a political nightmare. Still, some researchers have been redesigning nuclear reactors to make them safer in many ways, but these newer designs have yet to be scaled up and used commercially. Maybe someday nuclear technology will be ubiquitous, but it'll likely take a long time before anyone is willing to embrace fission/fusion energy that doesn't come from the Sun.

• A European research reactor called Guinevere demonstrates the safety and benefits of a hybrid reactor-accelerator design. This nuclear reactor design is an accelerator-driven system (ADS) and uses a particle accelerator so that its nuclear reactor can run without enough fissile material to generate a nuclear chain reaction (so all the nuclear reactions stop when the external particle accelerator stops). A bonus feature is that its radioactive waste material can be transmuted via the particle accelerator into elements with lower half-lives that may be more convenient to handle and store. [url]
• Teenager Taylor Wilson has been building nuclear reactors for a few years already, and his current project is to build small, modular nuclear reactors capable of generating just 50-100 megawatts of electricity. Wilson's reactors would create a more decentralized network of electricity generation, but that's a lot of NIMBY to overcome.... [url]
• Italian scientists have halted research on piezonuclear fission. Low Energy Nuclear Reactions have been associated with Cold Fusion, so if there's any kind of non-classical fission/fusion going on, it may take extraordinary evidence to convince anyone of it. [url]

If you happened to check your favorite major news site in the past 24 hours, you probably already know about this incredibly strange video North Korea's state media has been running, in which a peacefully sleeping Korean man dreams of a nuclear rocket detonating on American soil while Korean text is overlayed and Michael Jackson's "We Are The World" plays in the background.

Awww, we think about you when we're dreaming, too, you guys!

Now, since I can't translate Korean, I can only assume the text amounts to some kind of assertion that Michael Jackson was taken long before his time by a massive American military plot and that a nuke up our rectums will be issued as retribution. Really, who can tell? But I'll tell you what I can translate, and that's video game footage. I say this because it turns out that North Korea, in the tradition of the Chinese Air Force, apparently decided to simply yank a bunch of nuke footage from Modern Warfare 3 to use in this wonderfully disturbing bit of propaganda. This side by side will show you the rip.

Essentially, that terribly frightening part where New York is ablaze is all from MW3, with an additional explosion or two added along side a grainy filter and 'Ol Glory. For most normal people in The States, their reaction to this is probably, "So what?" But I know Techdirt readers aren't all in the States, nor are they normal, so I'm sure amongst your first thoughts was, "Hey! That's copyright infringement!" Well, the Forbes post got our juices flowing with this:

UPDATE: Activision actually DID have it killed, which is sort of hilarious.

America! So mark today as the day that copyright saved us all... And you people say we never have anything good to say about... Oh, wait... it turns out that the original video was actually taken down by the user who uploaded it (i.e., whatever North Korea's version of Ronaiah Tuiasosopo is), so it wasn't so much a victory for America! as it was a failure of America!'s media fact-checking efforts.

Someday, the world will run out of fossil fuels to burn. But maybe we can avoid running out of fossil fuels by figuring out another energy source, so we won't need to burn hydrocarbons to produce electricity. Nuclear fission is just one possible energy source that could potentially replace coal, oil and natural gas entirely -- but there are some obvious drawbacks such as long-term radioactivity from its waste and the possibility of creating more nuclear weapons. Nuclear technology keeps moving forward (whether or not we've figured out how to deal with WMDs), and here are just a few examples.

• Separating uranium-235 from the uranium-238 is a difficult process, but if there were an easier way to do it, nuclear proliferation could be a much bigger problem. Cheaper nuclear energy might solve a bunch of the world's problems, but it could also create a few new ones, too. [url]
• Kenya is looking to develop its own nuclear energy program at the the University of Nairobi. It's an ambitious goal, but Kenya wants to create a sustainable, reliable and affordable source of energy for its economy to become a middle-income country by 2030. [url]
• The ability to turn enriched uranium into weapons isn't a one-way trip -- about 20,000 of Russia's nuclear missiles will be turned into nuclear fuel for US power plants by 2013. A 1993 agreement between Russia and the USA has been turning 500 metric tons of Soviet weapons-grade uranium into electricity for America's cities. [url]

Some methods of flying are better than others. Passenger comfort isn't always the top priority for some aircraft, and that's especially true when engineers are trying out really novel designs and propulsion ideas. Here are just a few examples of some new planes that aren't quite ready for commercial flight, but that look really cool on the drawing board.

• A solar-powered plane prototype was demonstrated at the Paris Airshow. Unfortunately, the plane requires almost windless conditions to fly, and it's not too fast. But it *can* stay aloft almost indefinitely (greater than 24 hours so far). [url]
• The VoltAir is an all-electric plane concept with superconducting (!) electric motors... "VoltAir is an upstream research concept, not a near-term commercial approach." Duh. [url]
• If superconducting electric motors seem plausible, then using a low-energy nuclear reactor (LENR) to power a plane is just around the corner. I'd like a Mr. Fusion generator for my DeLorean, too. [url]

As oil prices fluctuate, so do the opinions of what to do about shifting away from fossil fuels. Gas prices seem to be going up, and that has boosted the calls for investment in alternative energy projects. Unfortunately, there's no clearly superior technology that's poised to take over. But there are plenty of opinions being thrown around -- here are just a few.

• Arnold Schwarzenegger wants to put huge solar power plants in the Mojave Desert to help reduce America's dependence on oil. But isn't there a nuclear battery in his chest (from a Skynet-dominated future...) that we can reverse engineer? [url]
• Critics of wind and wave energy say that the environmental impact of these sources could be harmful -- if they were actually used to produce significant amounts of energy. Ah, the good old truckload of vegetables tactic arises, again. [url]
• Bill Gates says nuclear power is the best energy solution -- and that other alternative energy technologies are merely cute. Bill Gates is right, though, nuclear power is definitely not cute. [url]
