I support this idea; small nuclear reactors could be an sollution for many things. It would de-centralise the power supply to lower the cost, and loss, of energy supply in general and would make it much less vulnereable against all sorts of attacks (e.g. terrorism).
Modern Gen-IV reactors are much safer than the "older" ones that are in use and the research on some of them is in development. They could already be deployed all over the world (some are already building some; like China builds at least one MSR) for much lower costs and much less construction time. Heck, they could even be build in modules to reduce the building time and the risk from construction flaws while building.

It could help us fighting against climate change!


But oh, yeah Chernobyl and Fukushima. Terrible, and both based on severe flaws non the less. But quiting the nuclear energy production sector because of it?

Speaking about my country; Germany; PLEASE let us build a few Gen IV Reactors. We got the expertice, we could even order some from other companys.

But instead were building an airport that costs billions and is nearly useless nowadays.



Or we could just wait til nuclear fussion is ready, giving it around 50-60 years if all goes well.

Fukushima Daiichi had its diesel backup generators in a basement. Bad idea. Fukushima Daini had a backup power source on a hillside behind the main plant. Worker ran thousands of feet of heavy cable to connect it to their pumps. They saved their reactors.

Chernobyl was just pee-poor all the way around. Even the KGB warned engineers about shortcomings and obvious dangers. All the warnings were ignored. What they had was doomed to fail at some point.

From what I gather, cold-fusion is the grail of energy production. I do not know if this is even possible. A few labs are attempting hot-fusion. They are having issues getting the temperature high enough for the chain-reaction to begin.

Several years ago, I saw a photo of a "magnetic bottle" taken at one of the major colleges in the Northeast U.S. It may have been MIT. Inside the bottle is a very small amount of anti-matter, so a short article read. Fact or fiction, I am not sure. If true, and they somehow lose suspension, well, I cannot imagine the consequences.

The consequences are very easily imaginable.

If you try very hard you could pick up the annihilation with sensitive gamma ray detectors a few cm or so away.

Cold fusion is undoubtedly possible and has already been demonstrated.

What has not been demonstrated is the ability to get more energy out than has been put in.

A few centimeters away. I suppose the reaction would depend on how much anti-matter was in the bottle?

Now that you mention it, I remember seeing a short video about cold-fusion a long time ago. Their device(s) were inside a very large round flask on a lab table. I believe the flask was filled with seawater.

I know that the TU Darmstadt in cooperation with the CERN and GSI/FAIR developed an transportation device (which was build by BNG; the company I am actually working for) similiar to a penning trap; but just larger. It has an magnetic field force from around 4 Tesla.


So yes it is true, and heck we made massive progress about antimatter research. I am happy to be a part of that, even if i "just" work on a few magnets

Inside The World's Largest Fusion Nuclear Reactor.

Perhaps others here can glean more from this than I can.

Going to their web site turned up WHAT IS ITER?

The text may be more informative than the video.

Note that fusion is the complete opposite of fission. There is no uranium or thorium used in fusion.

Not used. But it is how they are created. In stars...

I'm not sure rapid neutron capture ("r-process") qualifies as fusion...
