"Nuclear fusion will never be a practical source of electrical power,
argues a prominent scientist in the journal Science.

Even nuclear fusion's staunchest advocates admit a power-producing
fusion plant is still decades away at best, despite forty years of
hard work and well over $20 billion spent on the research. But the new
paper, personally backed by the journal's editor, issues a strong
challenge to the entire fusion programme, arguing that the whole
massive endeavour is never likely to lead to anything practical or
useful."

This is good news, finally somebody reveals that the emperor has no
clothes.

Fusion is vaporware, it will not happen in my lifetime, probably not
in this century.

Meanwhile, let us get on with the job of developing a true
limitless, safe and clean energy supply, Solar power Satellites.

We can deploy an SPS systen in 10 years, and become free from oil
and fossil fuels. That will save us (at least the USA) about
$200billion per year on the military costs of the war on terror,
which is really a war for energy control.

Thanks,

Cahrles R.

My own 2 cents is that we are trying to dupicate conditions that are found in the center of the sun. This is kinda a tough problem. And if the money invested in fusion went in maglev launchers for solar power satilletes we would probably be recieving power from the sun today. Plus a lot of other benefits from a cheap way to achiever low earth orbit.
But you know this is what basic research is all about, if we already knew what technologies would pay off with economic rewards...
Have to agree we have this beutiful stable fusion reactor only 93 million miles from every elementry school we know of, can you beat that?
You know also it is almost a truism that an old scientist is always too conservative and is almost always wrong about what can and can not be done.

I have this horrible speculative belief in the back of my mind that the reason this technology is not being looked into is because a wealthy group of powerful people want to keep people in subjections with fossil fuels they control.
They cannot put a switch on the sun, so they do not want to lose control in this world.

On the other hand, could this be a breakthrough?

Yeah. The obsession with oil is getting really close nuclear
holocaust. I am wondering if I will wake up to learn that Israel
has nuked Iranian nuclear facilities.

Then what?

I am remind of one of Arthur C. Clarke's laws, to wit,"When an elderly but distinguished scientist saws that something is possible , he is almost always right. When that same scientist says that somthing is impossible, he is almost always wrong".
We have produced fusion reactions. Our problem is sustaining and controlling them.

This a better explanation. It still leaves a lot to be desired. The
explanation is that something similar to mechanical friction transfered
energy into the plasma. It doesn't make sense to me. It doesn't matter
how the energy is stored or released. If the total energy released is
more than the input this explanation doesn't cover it.

The information available are mass media news releases and don't say
anything useful and mostly just cloud the picture.

Did anyone read the Feb. 24 issue of the journal Physical Review Letters
on this subject?

Our best hope for breakthroughs are from experiments where the results
are not what was expected just like this one. However I am not a
believer at this point.

The only thing I've thought of is perhaps even more preposterous than the energy levels reported as released. If it's substantially more energy released than merging or dividing atomic nuclei can possibly explain, what's the next step (one that may or may not have been acchieved in an accelerator)?

...and how the heck is it being acchieved and how do we replicate it in less esoteric circumstances?

Message Guys, let's keep the conversation confined to our current dependence on oilor the likelihood of fusion power, and off of politics. The former might relate to the importance ofSPS and hence to SSI research (the topic of this maillist). Opinions on the Bush administration can't be said to relate to SSI work.

Many Thanks,
Mike Combs

"As Michael HIrsh of Newsweek summed up in a recent column: 'How then did we arrive at this day, with anti-American Islamist governments rising in the Mideast, bin Laden sneering at us, Qaida lieutenants escaping from prison, Iran brazenly enriching uranium, and America as hated and mistrusted as it ever has been? The answer, in a word, is incompetence.'"
