Magnetic field researchers target 100-tesla goal

True, this type of research is the key to unlimited energy. A while back Rush said there was not such thing as renewable energy, I cracked up, he has no ideal how much energy the earth throws away each day in lighting strikes.

I cracked up because you apparently have no "ideal" that capturing lightening strikes would be CONVERTED energy, not renewable energy. Energy can be converted or stored, but not "renewed." Rush is correct.

Energy density of free space in 100 Tesla field is 3.98 gigajoules per cubic meter, or almost 4 kJ/cm³.

Energy density of a lithium battery is 1.3 kJ/cm³.
Energy density of gasoline is 34 kJ/cm³.

About the magnet:
http://www.magnet.fsu.edu/mediacenter/features/meetthemagnets/multishot.html
“...The field of this magnet lasts 15 milliseconds, allowing precise scientific measurements at the highest fields in the world. Although 15 milliseconds may not sound like much time, it is about two thousand times longer than what is otherwise available at this field intensity.”

[steve86]

Yeah, but is it renewable?

Best post of the week.

I once worked with a brilliant alumni of Los Alamos.

He had a theory that you could use very high magnetic fields to cause nuclear waste to give up energy at a fantastic rate. You could then use nuke waste for generating power.

He died before he was able to develop the theory fully.

Wrong, you can capture it from the earth, we just do not know how. And the earth makes new lighting every second some where.

[Mike Darancette]

Today’s 100.75-tesla performance produced research results for scientific teams from Rutgers University

That would make your blood clot?

I said that energy can be captured. It cannot be renewed.

And the earth makes new lighting every second some where.

So? Just because there is so much energy from that source that we cannot use it all does not mean that the release of charge is "renewed." That the earth has a magnetic field and generates Coriolis forces that produce electrical charges does not mean that the energy released in those discharges is "renewed." The Second Law of Thermodynamics and the conservation of energy say that there will be loss. The energy will not be renewed. The earth will slow in rotation and the sun will consume its hydrogen. Just because there just happens to be a lot of it does not mean that it will be "renewed."

I was just taking a break from my Thermodynamics studying, and I read this. Time for a break from my break. :)

How quickly they forget. Or never knew.

Serves you right! ;-)

Thermodynamics is a funny subject. The first time you go through it, you don't understand it at all. The second time you go through it, you think you understand it, except for one or two small points. The third time you go through it, you know you don't understand it, but by that time you are so used to it, it doesn't bother you any more. - Arnold Sommerfeld

Next break, try Isaac Asimov's short story, The Last Question.

How much do these guys make that they can afford 100 Teslas?

Must be the Tax Credits.

Watched an episode of “The Universe” a while back that was about what happens as the universe dissipates and runs out of energy. What matter is left will be so distant that it won’t be able to interact or be converted into energy.

Hah! Amateurs!

[COBOL2Java]

LOL! Ya beat me!

[EEGator]

Thanks for the link to the stories. Ironically enough, today I’m studying the entropy chapter.

[Carry_Okie]

Re your episode of “The Universe,” it’s a ripoff of Asimov’s idea written in the ‘50s, “The Last Question,” one of the most famous sci-fi short stories ever written. See the link in post 32 for an online version.
