If you had to frequently speed up and slow down, you might get a small net gain in efficiency. When your foot is off of the gas (?) pedal, the electric usage is zero, but the fan is still producing energy.

A similar idea is used in electric cars with magnetic brakes. They slow the car with electromagnets and charge the battery at the same time.

Gravity is such a weakling.

The electromagnetic coupling constant is approximately
10 000 000 000 000 000 000 000 000 000 000 000 000 000 000 times larger than its gravitational counterpart.
Take that, gravity!

Doesn't this guy sort of sound like George W. Bush, except that he can string a complete sentence together and correctly pronounce words with more than one syllable?

Still can't pronounce aluminium correctly.

Prepare to have your minds blown. Aluminum is both the correct spelling and pronunciation given by the man who first isolated the metal, Humphrey Davey. The American insistence on pronouncing it correctly only reflects our respect for scientists, even British ones.


Bah, he was never too sure himself.

He originally called it Alumium, used Aluminum in his book Chemical Philosphy, and Aluminium on his patent filings.

Even the Wikipedia page for Aluminum redirects to Aluminium, so it must be true.

"Now, if you're like me you might be asking yourself, 'Hey SuperMagnetMan, what would happen if I inserted a large magnet into my rectum?' Well, I think this impressive demonstration will really blow your mind...">> ^nach0s:

That guy seems simultaneously very friendly and incredibly creepy

Sometimes, to learn something really cool, you have to put yourself at risk of non-consensual intercourse.

NOW DROP IT FROM TEN FEET! giddy laughter


Looks like he might have tried that by the huge chip missing from the magnet.
