Will fusion reactors will be the most efficient and powerful energy source in the near future? (First to be built in 2025)

Asked by: PetersSmith
  • It absolutely will

    The US and Europe are already very close to achieving hot fusion, using two different methods. There are also various experimental methods of achieving cold fusion. Once we have fusion power perfected and are able to harvest the energy from it, it will completely revolutionize the world. With fusion, you actually get more energy out of the reaction than you put in. Also, unlike a traditional fission nuclear power plant, there is much less radioactive waste. Fusion power will be incredibly cheap and plentiful, and will open a door for better military technology, send men into deep space again, reboost economies, and allow the US to return to the state we were in the 1950's.

  • Future fusion reactor..

    As per the demand of energy the alternative way must need to be developed. We have taken a small step towards it by establishing the ITER project.Our aim in this prototype fusion reactor is to have 10 fold gain. For its success we must have to begin with positive attitude.

  • Fusion smaller, cheaper, and sooner than almost anyone now anticipates

    Some people like the idea of fusion and an abundant energy generator that produces non-radioactive helium as its nuclear waste. What is less exciting is the fact that only one type of nuclear fusion has ever produced net energy (more energy out of the fusion experiment than it takes to run the fusion experiment). That form of fusion is "impure fission-fusion" that uses the power of fission to create the conditions needed for fusion.
    There is real reason to be optimistic about fusion today (not just hype and rah-rah). Several small pure fusion experiments are getting genuinely close to achieving "break-even" and fusion ignition.
    Here is a link to an article at The Next Big Future Blog that does a good job reviewing the current status.

    In the states that have effective legal moratoriums against nuclear, new fission reactors cannot be built. If you want to install reliable on demand nuclear energy in those states comprising something approaching 30% of US population, the only choice is nuclear fusion.

    The California Energy Commission is now considering two requests for EPIC 2015-2017 research funding into technology to provide reliable power to replace what was recently lost when the two San Onofre nuclear reactors were shuttered. Out of 103 proposals submitted to CEC, two are nuclear (one Gen-IV fission and one Inertial Confinement fusion). Of the two proposals, only the ICF fusion proposal could be operated in the State of California without changing California law (Cal.Pub.Res.Code § 25524.1) requiring that NRC designate an approved method for permanently handling high level nuclear waste.

    . The current (CEC TN-72616) pure inertial confinement hybrid D-T/D-D fusion design uses a staged design target that allows a minimum amount of Tritium in a D-T capsule to ignite a much larger amount of pressurized deuterium cryo-liquid held in a long thin pressurized cylinder. The D-T initiator or "sparkplug" is tiny: only 170 microgram of D-T in a spherical fusion capsule which is ignited by the fusion driver. The D-T initiator in turn is used to initiate a detonation wave of in the long thin pressurized cylinder of cryogenic liquid Deuterium (D-D fusion). The majority of the energy produced by the hybrid staged small fusion device is from cheap, sustainable, deuterium D-D fusion. The two stage CEC TN-72616 minimizes both the amount of tritium that has to be produced and stored to make fusion targets and also makes possible a tunable yield – conveniently adjusted to best economic size just by changing the length of the pressurized cryo-deuterium cylinder.

  • I'm a skeptic. I say no.

    I'm a skeptic. I say no. I actually do know quite a bit about nuclear fusion. It does happen inside of stars, where temperatures are astronomically hot and the pressure is extremely high. However, even the rate at which nuclear fusion takes place inside of stars is considered too slow and therefore impractical for the generation of electricity for human use.

    So far, all experiments that have attempted fusion have required more energy as input than they actually have given off. It is for these reasons and many others that I'm a skeptic on the possibility of nuclear power plants that facilitate nuclear fusion reactions.

    Modern day fission reactions require cooling rods to sustain temperatures needed to allow safe fission reactions to take place inside of nuclear power plants, but scientists point out that, because of the incredible temperatures required for nuclear fusion to take place, oceans of water would be required to keep such hypothetical power plants cool. Another problem is that there is no conceivable way to contain the hot plasma that is required to produce nuclear fusion (plasma consist of atoms traveling at very high speeds that have been stripped of their electrons; these particle would produce temperatures as hot as that found on the sun.).

    Also, temperatures can hypothetically be reduced quite a bit in man-made nuclear fusion reactions if they rely on quantum effects such as quantum tunneling to overcome the Columb barrier and allow nuclei to fuse; but even then temperatures would have to be astronomically high.

    If scientists successfully achieve nuclear fusion that can generate electricity for civilizations, it would be a huge breakthrough because these types of nuclear reactions wouldn't produce radioactive nuclear wastes.

    However, because of the incredible difficulties involved (that have not yet been practically overcome) I remain a skeptic on nuclear fusion's capacity to generate electricity for humankind.

Personally, I don't think the world will be around long enough for any to be built.
