I will not take up space reciting quotes from the NSSO report about the pros and con of SPS. I will provide a link to the report. Then we can comment/debate...
The problem with hydrogen has very little to do with its "explosive personality"... aside from it being a gas. Gasoline is 3x more explosive than hydrogen. ...
Your signature, "We live in an imperfectly imperfect world. If we lived in a perfectly imperfect world things would be a lot better." is amusing. Of course,...

There were a number of manned programs going at the time, and a big political brew-haha over which should get the lion's share of the funding. The deciding...

That doesn't really have much to do with Warren Smith's magnetic catapult. Smith proposes a linear sequence of superconducting coils (hoops, really) which when...

The point of raising the muzzle up high is to avoid turning the projectile into a puff of smoke when it hits the air. When I wrote earlier, I thought a vacuum...

I know this isn't really that news nanotubes can be used in electronics, but the fact that they are moving out of the lab, into production is a positive step. ...
EVANSTON, Ill. --- For more than 15 years, carbon nanotubes (CNTs) have been the flagship material of nanotechnology. Researchers have conceived applications...
CNT is strong theoretically. When lattice defects found in the real world are included the theoretical numbers drop to a small fraction of the original values....

John, what kind of efficiency was achieved? Every vision is a joke until the first man accomplishes it; once realized, it becomes commonplace. ~Robert...
John, congratulations, that's great you were involved. I attended the press conference this morning and have a bunch of notes, if you have any questions about...
I was pleasantly surprised at the results. The entire set up appeared to be sort of a jerry-rigged affair. A mile from the transmitter the team measured...
Craig, You obviously know alot about this. Can you explain beam bifurcation? Why are they measureing in decibells and not watts? Why did they say they hit...
I was rather disappointed in the show. I suspect it was made to impress people who aren't very technical, and if it does that it's probably a good thing....
