Why does't we build a huge nuclear fussion reactor?

Question

I mean a Huge Nuclear Fussion reactor that will be enormous in size and it will be built with the WHOLE worlds co-operation.It will not only meet the needs of the country in which it is situated but also the WHOLE world.Your viewpoints in this direction?

Answer 1

Bamma say you have an excellent idea on your hands. Bamma say imagine a future where energy is beamed into your home from satellites. Bamma say everything cordless. Bamma say even flashlights run that way. Bamma say everrrrrrrrrything run that way. Bamma say cars, planes, ships, everrrrrything. Even your toothbrush. Bamma give you something new to design. Bamma say get to work. Bamma say so.

Answer 2

Well, first of all, we have not yet succeeded in producing electricity at an industrial level in a small , experimental fusion reactor. One new reactor will be build in the coming years in France and the world's scientific community will work on experimenting a number of things on this one. We are not yet sure about how it must be exactly designed, we have not yet solved many different technical issues, so it is much too early to start making an industrial reactor.
The second reason is that you may not say that bigger means more powerful. It has been proved that the ring where the fusion will be done must have a minimal size (a few meters - a few tens of inches). Smaller rings would not be able to produce energy. But also, I think that there are reasons to think that a huge fusion reactor would be less efficient that many small reactors.
The third reason is the transport of electricity. Today, when we transport electricity between cities, a big part of the electricity is lost (the "Joule" effect transform a significant part of the electricity in heat). So, transporting electricity from, let say, Australia to Canada, would waste more than 90% of it and you would only get a very small portion of it at the end.
So... It is not so easy...

However, what is good is that it seems that, for the moment, most industrialized countries in the world are joining their research efforts on nuclear fusion, which is already a very good news, no ?


Finally, don't confuse nuclear fission and fusion. Current nuclear power plants are using "fission", are used since a lot of time, produce energy, are dangerous (at least if strong security rules are not strictly followed) and produce a lot of waste (which I consider less a problem than sending a lot of CO2 in the air when burning oil, but that's another problem). Fusion plants are still being invented, will (maybe) produce much more energy with much less fuel. The fuel will be simply extracted from water, they will be much less dangerous and will produce much less waste.

Answer 3

They're building one in France right now. The project (ITER) involves several European nations, Japan, the US and others. Nature had run several articles on it. This is really the first large scale fussion reactor that can be used to provide power to a town. It will take few years before it is completed.

Answer 4

It would be a wonderful idea if we could figure out a way to make it safe, and how to dispose of the nuclear waste.

Answer 5

We don't know how, yet, to contain and maintain the fusion (1 ess) reaction for more than a tiny fraction of a second.

Answer 6

a small one for just one city costs so much and has so much danger involved they havent built one in the us for years. the whole world simply would not chip in anyway.
