    Laser Controlled Hydrogen Fusion To Solve Energy Needs

    Death Star-esque laser to solve power crisis (PHOTOS)

    In a project fifteen years in the making, scientists have created a record-breaking laser that could solve the energy crisis for good. The US National Ignition Facility is now one step closer to generating a controllable nuclear fusion reaction.

    The American National Ignition Facility (NIF) has entered the encyclopedias by generating a 500 terawatt shot, simultaneously using 192 beams. In simpler terms, that's “1,000 times more power than the United States uses at any instant in time, and … about 100 times what any other laser regularly produces today” says the NIF.

    Due to the manner in which the multiple beams converge to focus extreme levels of energy and ultimately power on a specific target, some have likened it to the Death Star, the moon-sized station from the Star Wars movies.

    And while not as powerful as the fictional space station's massive death ray, the NIF's ultraviolet lasers will heat their target to hundreds of millions of degrees, thereby “igniting hydrogen fusion fuel in the laboratory and producing more energy than that supplied to the target.”

    This, in the long run, would mean controlled fusion, as opposed to the uncontrolled form found in the hydrogen bomb.

    The NIF's Initial fears about reaching such heights of laser performance centered on the quality of optics available in the 1990s.

    The main fear then was that the available material would not endure the intensity of a laser beam. NIF personnel and their partners worked tirelessly to improve the manufacturing methods and significantly lower the incidence of defects. They also developed "in-house procedures to remove and mitigate small amounts of damage resulting from repeated laser firings."

    “It is fully operational, and scientists are taking important steps toward the quest for clean fusion energy,”
    says NIF Director Edward Moses.

    But environmental groups warn that research into fusion will redirect much-needed funding from proven alternative energy technologies such as wind and hydro power.

    The NIF is now lobbying for the development of new giant laser facilities in China, France, Japan, Russia and the United Kingdom.

    Seen from above, each of NIF's two identical laser bays has two clusters of 48 beamlines, one on either side of the utility spine running down the middle of the bay (Photo from www.llnl.gov)



    NIF's power conditioning system has more than 160 kilometers of high-voltage cable, which delivers energy to the system's 7,680 flashlamps (Photo from www.llnl.gov)

    NIF's final optics inspection system, when extended into the target chamber from a diagnostic instrument manipulator, can produce images of all 192 beamline final optics assemblies (Photo from www.llnl.gov)

    Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside in a cloud of smoke, thoroughly used up, totally worn out, and loudly proclaiming "Wow! What a Ride!"

    I doubt that. At this stage it is science, not technology ready to be deployed. The two methods, laser and magnetic enclosure have been developed in parallel for decades now. And the competing teams are scientists enough to be happy about every success, even while fiercely competetive.

    I believe the magnetic enclosure, either Tokamak or Stellarator will be the technology more likely to produce production facilities. That laser array is huge and hugely complex and while it now has obtained break even it is nowhere near able to operate continuously.

    The next generation Stellarator will go in service in 2014 and they will hopefully be able to achieve break even not for a single shot of a fraction of a second but for extended periods. It is like its predecessor Iter a joint effort by the EU, Russia, Japan and China, and probably others.

    One of 50 superconducting electromagnets. No two are the same, each one was calculated and built differently to form one enclosure for the plasma.

    After inputting the data to my scientific calculator I got this result..




    ..which means that the power produced in this short 'shot' experiment is sufficient to power the constant input required for the constant output..

    That amount of energy is used in an extremely short fraction of a second. It comes out of condensors which are charged for an hour before they can be discharged for a microsecond or whatever. I could not find the exact time.

    As a sustained production it would be 100 times the energy consumed in the US in total.

    I very much hope all the best for the scientists working on fusion. You are very important, global warming creeping up, keep up your strenght.

    Good luck to them !! it's about time that we had something to cure the World of it's addiction to Oil ...
    It can only change the World for the better , now lets just get rid of all those Arms and munitions ...
    No weapons , no Oil usage = a shit load of money left to turn the World into an educated , hunger free place for all ......
    Travel lightly ....

    Sorry to say that.

    But you are way off the mark. Most poor countries with uneducated and hungry people are not what they are for lack of funds and resources. They are because their local overlords chose them to be that way to keep them under control. No amount of foreign funding will change anything.

    You need oil to make the tires that carry people to work on this fantasy.

    You need oil to make the roads that the cars ride on to carry people to work to earn the money to pay the taxes to pay for these technological delusions.

    You need oil to make the pesiticides to grow the crops to feed the scientists.

    You need oil to make the fertilizers to feed the people who pay the taxes for this thing.

    You need oil to make the antibiotics.....

    the list goes on for about a hundred pages.


    There will be no magic energy fix.

    You are not wrong. But if Fusion would become possible and economically sound the carbon footprint could become much smaller. Imagine all those powerplants that could be replaced. Those that are burning coal or are burning oil that is needed for the purposes you listed.

    No magic required. Oil is a finite resource. Mankind will adapt. As always.

    That is one of the reasons I believe, an important part of the solution will be producing carbohydrates with algae or some similar artificial organism. Because that can really replace oil.

    I personally believe it will some GM or completely artificial organism. And we will need another 30 to 50 years to aquire the the required knowledge.

    But if we can get Fusion to work it will certainly help.

    Exactly my point. and to see what the world may look like when the oil runs out go look at the world before oil was discovered.

    but if you think people will be driving 'fusion' cars to get their loaf of bread, think again. Think 'horse' instead.

    Once oil runs out food and as a result fat people will be in short supply soon after.

    That's ok, fat people use more oil, so with less of them it will be a self regulating problem.

    Yes, before oil the planet seemed to support a billion or so. Now it is 7 billion. When the oil runs out it will go back to a billion or two. Should be a very interesting transition indeed.

    As I said there are other sources besides oil you can make things of. It will only become more expensive. Also there will be no cutoff from oil for a long long time. Only not enough and too expensive to drive the present style econonmy with.

    Also you can make oil products from coal, using hydrogen. And coal there is a lot more than oil. What we need is energy to make all these things.

    And again algae or synthetic organisms to provide all those raw materials directly from sunlight.
    Everything being much easier if we reduce the world population to below 1 billion people.
