Nuclear fusion energy is regarded as critically important for our energy future.
I totally agree that it has tremendous potential. But I also feel that many other types of safe and affordable energy are being largely ignored by governments, the international scientific community, and international news services.
In any case, a major advance in nuclear fusion efforts was recently announced. The following is a link that briefly discusses that advance.
https://www.youtube.com/watch?v=b8l43hrDcJ8
What has happened is that a nuclear fusion research facility in Great Britain managed to keep a nuclear fusion plasma running for 5 seconds. I believe that the previous record was just one second or less.
These plasmas are so unstable and difficult to control that 5 seconds would have to be regarded as a major step forward.
The plasma lasted only 5 seconds because the magnetic coils used to keep it contained got overheated. I believe that that was expected.
Those coils relied on conventional magnetic coil technology rather than superconducting magnets.
A GIGANTIC nuclear fusion reactor being built in France by a consortium of nations does rely on superconducting magnets.
This latest advance was regarded as being especially important because it provided critically important information regarding the chances that the larger reactor would actually work.
These are personal opinions.

Hi Ryan,
A bite! At last! Hurrah!
What I am saying is that I don’t very often get a chance to discuss some topic with other scientists and attempt to convince them that their opinions should change.
ENOUGH SAFE ENERGY
“IF THERE ISN’T ENOUGH SAFE AND AFFORDABLE ENERGY FOR EVERONE ON THE PLANET THEN THERE ISN’T ENOUGH FOR ANYONE”
You can quote me on that. However, I am probably not the first or only person to ever say that.
One of humanity’s greatest and most deadly problems is our global lack of environmentally safe and affordable energy.
With adequate supplies of energy we can solve most (but not all) of our other serious problems and theoretically, even reduce our tax bills.
That tax bill matter is theoretical because government officials consider it to be a basic law of the universe that they can and should impose any taxes they wish on the general public. They DO actually think that way regardless of what they might say in public.
Unfortunately, there aren’t too many sources of safe and affordable energy available to us. Even solar and wind have problems associated with them.
SOLAR takes up lots of space and usually involves creating solar panels that can contain harmful chemicals. Eventually, those panels will stop working and will have to be disposed of etc. Then the harmful chemical can cause problems. Also, to get the elements needed for the solar panels, people need to dig deep in the earth resulting in the problems that are often associated with mines. Solar energy also obviously doesn’t work when the sun is not shining.
WIND turbines cost a fair amount of money to build. They also take up lots of land. They are usually noisy. And they can destroy animals such as birds that fly into them. Wind energy also obviously doesn’t work when there isn’t some type of breeze.
NUCLEAR FISSION energy could be solving most of our energy needs. But it has numerous, enormous, deadly serious problems associated with it.
Most of them have to do with carelessness resulting from stupidity and greed associated with the people who design and build the nuclear fission power plants.
NUCLEAR FUSION has its own problems. But they are nowhere near as serious as those associated with nuclear fission or even fossil fuel energy or renewable energy problems.
The main nuclear fusion problem is often summarized with the popular saying that:
“PRACTICAL NUCLEAR FUSION ENERGY IS 30 YEARS AWAY. 30 YEARS FROM NOW IT WILL STILL BE 30 YEARS AWAY!”
Designing and building nuclear fusion reactors that can keep a 100 million degree plasma from getting lose and melting the container vessel is presently the main problem associated with nuclear fusion energy.
Once corporations and/or governments have that problem solved, nuclear fusion should be relatively safe and inexpensive to use.
There will still be problems with lengthy electric power lines etc. But, extremely serious problems associated with nuclear fission meltdowns will not exist. If the nuclear fusion power plant fails it will only cause a few problems in the vicinity of the power plant. The plant will simply stop running. There won’t be any explosions or major fires. There won’t be radioactive gas and dust scattered everywhere.
COAL fired power plants circulate more radioactive gas and dust than either nuclear fission or fusion plants do or will. This is associated with elements like uranium and radon in the coal being sent into the atmosphere when the coal is burned.
MOST nuclear fusion plants will generate large numbers of neutrons that can cause the container walls to gradually weaken and fail. But scientists can easily predict how many years etc. that will take and then make plans to replace the container walls in plenty of time.
SOME nuclear fusion plants have designs where they don’t generate massive number of neutrons like that. But, getting them to generate practical amounts of energy is still a problem that needs to be solved.
MANY BILLIONS AND BILLIONS OF DOLLARS IN RESEARCH FUNDING ARE PRESENTLY BEING SPENT ON DEVELOPING NUCLEAR FUSION ENERGY PLANTS
We DO want practical nuclear fusion plans to get designed and running as quickly as possible. They should be able to generate all of the energy that humans around the world will need.
However, regardless of what nuclear fusion energy proponents keep saying, don’t hold your breath for the day when any of those plants are actually up and running.
In the mean time we are being forced to rely on coal, oil, natural gas, nuclear fission, and at times problematic renewable sources of energy.
Over the years, i have done a lot of research related to energy sources and have repeatedly contacted world governments and scientists about our lack of adequate amounts of environmentally safe and affordable energy.
People who want to discuss this further can just post a note here in response to this one.
Remember that I check this forum only a few times a week. It might take a little while for me to respond to your post.
Finally,
I have still been unable to get any large groups of computer programmers interested in translating my Earthquake Forecasting computer program from perl into a more modern language.
The plan is to have them discuss their efforts on this forum SCIENCE Web page. The efforts are still underway. I don’t give up very easily with important efforts like that.
These are personal opinions.
Regards to all.

Ryan's Question: Who needs all of that energy?
THE NEED FOR AFFORDABLE ENERGY
Have you looked at your electricity bill lately?
Have you considered how much you spend on car or truck fuel or home natural gas or heating oil every year?
Adequate supplies of environmentally safe, affordable energy would quickly drive electric bills and other energy bills down. Additionally, there is a strong international move towards electric cars. So, keeping electricity costs down would reduce the cost of running an electric car.
People are starving or are short of clean drinking water in many parts of the world. With enough energy, those food and water problems could be largely eliminated. Even if a country does not have access to ocean water or other sources of water that could be desalinated or purified, with enough energy they could easily condense water contained in the atmosphere and then use the water for drinking and irrigation.
People living in many countries are threatened by diseases such as malaria that are spread by mosquitoes. This is reportedly even starting to become a problem in the U.S.
With adequate supplies of low cost energy, countries could better deal with their mosquito problems.
Plastic pollution is now a major problem for our oceans. With enough cheap energy to propel them, robot ships could travel around the ocean, collect plastic waste, and transport it to some location where it could safely decompose or be recycled.
Wars such as the one in Ukraine are being fought partly over energy resources. If every country had enough energy there would be little reason for any country to go to war to get control over oil resources.
Think how much money could be saved if the U.S. and other countries were not spending billions of dollars every year to produce weapons for use in countries such as Ukraine.
From what I can see, the following is only rarely if ever discussed in the news:
Ukraine is a major source of food including wheat. So, part of that war in Ukraine is being fought over control of the land that produces the wheat.
If every country had enough energy to grow its own food, that demand for Ukraine wheat would not be as strong. Efforts to gain or keep control of the farmland in Ukraine might not be contributing to the war that is taking place there.
As a result of all of this, many of the lives that are presently being lost in the Ukraine war might be saved.
These are personal opinions.
