Comment Another Fusion Idea (Score 1) 199

Though I think fusion is not a short term viable option for commercial energy production. There is another way of doing this though. Fusion using helium 3 is most likely to produce a commercially viable reactor. But the problem is, there is hardly any helium 3 on the earth. We can produce it in another reactor, but the cost would be beyond commercial sustainability. However, there is theoretically a considerable source of helium 3 on the moon. Helium 3 is a product of solar wind that is mostly deflected by the earth's magnetic field. So it does not accumulate here. But the moon has no way of deflecting solar wind, so helium 3 can and does accumulate in the lunar regolith. This could actually make a return to the moon economically feasible. The most likely candidate for a commercially feasible fusion reactor would use helium3. It appears to be the most efficient means of creating distributable energy from a fusion based energy economy. But I still think thorium is a better and cheaper solution.

This will mean more and more hydrocarbons will have to be used to sustain the German economy. This is a hysterical political response from form uniformed and misguided environmental do gooders. I made an earlier post in another article about thorium reactors. These have no where the dangerous consequences of uranium/plutonium reactors. Thorium reactors have already been built in the US. But the reason why they never went commercial is because you cannot produce nuclear weapons from them in a practical sense.They better hope that fusion becomes viable soon. But I doubt it. People need to be more educated themselves and stop listening to lying politicians and self serving demagogues of fanciful ideologies.

While I understand your concerns about nuclear waste. The problems of thorium vs uranium reactor waste is substantially different. Much of the fuel in a uranium reactor leaves fissionable products that must be reprocessed into new fuel. This processing also allows for the production of weapons grade materials. If it is not processed, it remains hazardous for many thousands of years. This is not the case with a thorium LFTR reactor. As a matter of fact, an LFTR can actually utilize some of the waste left over from a uranium reactor and burn it up as fuel too. Yes, there will be some products left over from an LFTR that will be hazardous. But it is a tiny fraction of the waste from a uranium/plutonium reactor. The little that does remain from an LFTR would only be hazardous for a few centuries, not countless millenia.

Fusion is probably going to take huge expensive and sophisticated facilities to produce an economically viable power reactor. To some point (not completely though) I think much of this has been just government works projects. On the other hand thorium nuclear reactors could be exploited for far less money and much quicker. Thorium is a fairly abundant element that does not have many of the negative properties which a plutonium or uranium based react would have. We have to do something to beef up the electrical grid. I read an article that said if 10% of the cars in the USA switched to electric, it would collapse the capacity of the grid. Besides, most electricity here is now generated by coal. Please look into the more promising technology of the liquid fluoride thorium reactor (LFTR). http://en.wikipedia.org/wiki/LFTR http://www.youtube.com/watch?v=AZR0UKxNPh8 I'm not saying we should stop research on fusion, but we have to have a quickly viable alternative.

Submission + - Reflective LCD Technology 2

RudyHartmann writes: "Dr. R. A. Munson from Caltech University has recently discovered a commonly overlooked property of LCD’s. Many of the LCD flat panel monitors today are capable of turning each tiny pixel into a reflective mirror. This technology effectively turns most modern LCD monitors into a large and fairly good reflective mirror. Though the technology is not perfect, it is easy to demonstrate.

The viewable angle on many LCD monitors is limited, so be sure to position yourself squarely in front before you attempt this technology demo. The settings to do this work very quickly, so get ready..Just go to the link below to test it out. You’ll be amazed and like it!

While I agree with much of what you say. The uranium 233 that would be produced from an LFTR also contains a significant amount of U232. This stuff emits strong gamma rays as it decays. It is very deadly to handle. It would quickly ruin any electronics and many other materials in close proximity to it. There's enough of it in the U233 to be a significant obstacle to weaponize it. Though the ionic separation of it would leave you with only U233, but how tough would that be? It would be easier to separate the U235 out of naturally occurring uranium. In a practical sense, making weapons from this type of reactor would be overly costly, time consuming, and just plain dumb.

Uranium based reactors do create Plutonium. But in a Thorium based reactor for all practical purposes you do not. The reason why Uranium was preferred over Thorium for energy production is only BECAUSE of nuclear weapons. You cannot make practical weapons using a Thorium reactor. The chemical separation of actinides from spent fuel could also be used in a Thorium to create more energy from it. Elaborate and expensive ionic separation on not required. The basic idea a fusion is seductive, but so far it has only been a government make work project. Thorium reactors have actually been built and are functioning. Of course the most advanced to of a Thorium reactor would be e liquid fluoride thorium reactor (LFTR). The only reason these have not been built in mass quantities is engineering details. Fusion reactors are still pie-in-the-sky.
