What are the difficulties of fusion?
Some difficulties of fusion include achieving and sustaining high enough temperatures and pressures to initiate fusion reactions, containing and controlling the extremely hot plasma, managing the intense radiation produced, and designing materials that can withstand the extreme conditions inside a fusion reactor. Additionally, the current technology is still undergoing research and development, requiring substantial investment and time before commercial fusion power can be achieved.
What are some changes that happened with lasers throughout the years?
laser, bigger laser, fusion reactor.
What are some advantages to using a fusion reactor to produce electricity?
Some advantages of using a fusion reactor to produce electricity are the abundance of fuel sources like hydrogen isotopes, minimal greenhouse gas emissions, high energy output, and inherently safe operation with no risk of runaway reactions.
What are some reasons why no practical fusion reactor has yet been developed?
Challenges in controlling plasma at extremely high temperatures, finding materials that can withstand harsh conditions, and high energy costs required for research and development are some reasons why practical fusion reactors have not been developed yet. Additional factors include the complexity of the technology, regulatory hurdles, and the need for international collaboration.
What are the technical problems related to nuclear fusion?
Nuclear fusion requires very high temperatures and immense pressures to start and continue. The problems with a nuclear fusion reactor would be:- 1) the high temperatures would melt the container: therefore, the reaction would have to be stored in a vacuum suspended by a magnetic field and the reactor would have to be continually cooled. 2) nuclear fusion occurs naturally in stars such as our sun: unless the fusion reaction was limited in size in some way, it would be likely that our planet is vapourised by the reaction.
Could a fusion reactor be used as a time machine?
Could a fusion reactor be used as a time machine?Hmmm... We don't know. At least us mere mortals don't know - yet. There may be some physicists that know, but they are not talking.Certainly, there is tremendous energy available in a fusion reaction, possibly even enough to accelerate an object to near relativistic speed and make the Lorentz transformations take effect, but I would wonder how "squashed" that object would be.For now, lets settle on "no, a fusion reactor can not be used as a time machine".Followup:That answer was somewhat tongue in cheek, because the Lorentz transformations can only dilate or contract time, they cannot, to the best of our knowledge, change time. The answer remains, "no".
Outline the major difficulties in achieving controlled fusion?
1. You need to contain the material. If it blows apart, it isn't contained. 1a. Fusing H to make He, means you are working with gases at STP. 1b. How do you handle the waste (He)? 1c. How do you capture and use the energy that is released? (Ye olde steam engine?) 1d. How do you feed the reaction? (Is it merely one explosion?) 2. How do you get a permit to allow you to experiment (local, state, federal)? May I suggest experimenting not in Manhattan but in Arizona?
Where can nuclear reactions occur?
One type of nuclear reactions is fusion. This usually occur under extreme conditions - extreme temperatures and pressures. This most commonly occurs in the center of stars (including our Sun); in some cases also on the surface of a star (when matter falls onto the star, temporarily producing the high temperatures required). So far, it it not economically practical to do this artificially (search for "fusion reactor") - except for the destructive H-bomb. Fusion reactions usually occur if sufficient amounts of Uranium or some other heavy elements come together. This is the case with a nuclear reactor, and an atomic bomb.
What problems must be overcome before fusion can be used to produce energy?
Some of the key challenges that need to be overcome before fusion can be used to produce energy include achieving and sustaining the necessary high temperatures and pressures for fusion reactions to occur, developing materials that can withstand the extreme conditions inside a fusion reactor, finding ways to efficiently convert the fusion energy into electricity, and addressing the high cost and complexity of building and operating fusion reactors.
What are the by-products of nuclear fusion?
In general, nuclear fusion produces a new atom (or, in some cases, two atoms), a change in the amount of heat present and possibly some other emission. The specific products of nuclear fusion depend on what is being fused. The fusion of 2H + 2H produces 3H + a proton + 4.02 MeV The fusion of 2H + 3H produces 4He + a neutron + 17.6 MeV The fusion of 6Li + 2H can produce 4He + 4He + 22.4 MeV In the cases where fusion produces atoms heavier than iron, the reaction is endothermic, consuming heat rather than producing it.
How many pounds of uranium are in a nuclear reactor?
The quantity depends on: the type of the reactor, power of the reactor, enrichment of uraniu, chemical form of the fuel, etc. For a research reactor some kilograms, for a power reactor more than 100 tonnes/year.
What books are a part of the CCIE Professional Development Series?
There are many different books regarding CCIE Professional Development Series, some of the titles include: Cisco LAN Switching, Troubleshooting IP Difficulties, and Network Technology and Solutions.
