Comment Ridiculous (Score 1, Informative) 521

A semi-ridiculous idea.

It takes 200 million BTU equivalent of eletcricity to refine a ton of aluminum.

That's about the equivalent of 1,800 gallons of gasoline.

If using aluminum for the truck body ups the efficiency by 5 MPG, that would save 200 gallons for every 100,000 miles driven.

So you're still about 1,300 gallons in the hole.

A bad idea.

Comment Sounds like purest balderdash (Score 1) 45

The physics of antennas is pretty darn basic electrodynamics. You need a quarter to half a wavelength to make an efficient antenna. Scientists and engineers have tried for well over a century to overcome that limitation, with not much success. It's pretty basic-- if you want to set up an EM field, you need to be able to have charges separated by a goodly amount relative to the wavelength. The emitting material is irrelevant, in fact you need a really good conductor as you make the antenna shorter, as it's radiation resistance goes way down with length. Gaphene not only does not seem to have any advantage, it's high resistance is a big disadvantage. Sounds super highly fishy.

Comment Really, really, really ridiculous. (Score 1) 176

Cmon, converting electric power to radio frequency AC is at best 80% efficient, and coupling it maybe 50% at best, and converting it back to DC 80% again. I get 32% best efficiency and those are for the most optimum situation. No way this will ever fly, economically. And since people are scared of their water meters e-field of a fraction of a watt, how are they going to feel about megawatts? Not gonna fly, or even crawl.

Comment Don't (Score 0) 310

Don't even think of "helping".

I have tried doing just that, at least 3 times. It's never appreciated by mgmt. They either already know, or have been actively avoiding learning about these problems, or are unwilling to spend money on it. They will either frown, deny your facts, not follow up on your suggestions, or just plain fire you for not being a team player. Been there, tried to "help", got canned twice, now I don't squawk about the SQL injection issues, phishing, spam, etc, etc, etc.

Just start looking for another job, with luck, at a less clueless place.

Here's a hint. Any time you see a press release from a company or University PR department, ignore it. It's usually much worse than no information at all.

In this case they MAY have figured out how to lay down a supercapacitor on the back side of a silicon chip. Big whoop. You're talking about a few Farads at a few volts at most. Not a lot of energy storage possible there, certainly not enough to run a cell phone for more than a few seconds.

Comment Watch the tazing videos on YouTube (Score 1) 936

Get a bit better perspective on this by watching the tazing videos on YouTube.

Basically, it seems, if you repeatedly refuse to follow a simple police command, like "get out of the vehicle" or "lay down on the ground", after 10 or 20 repetitions, the cops have the option of tazing you. Apparently this is SOP. The old-school way was to chicken choke or baton-choke you. You decide which is better.

Comment Laws of Physics. (Score 1) 590

let's say it's high noon and you have a plane with every outside surface covered with solar cells.

Now a 747-400 has a wing area of around 6000 square feet.

Full sunlight falling on 6000 square feet, or about 666 square yards, generates about 100,000 watts.

There are 746 watts per horsepower, so you have about 134 horsepower to work with.

Unfortunately a 747-400 needs about 80,000 horses just to stay in the air.

We are only about a factor of 600 short on the horsepower front.

Comment Moderately ridiculous sounding. (Score 1) 357

Ah yes, all we have to do is find an algebraic equation whose 1542 roots happen to match packet #1767 of the Angry Birds video. And whose coefficients take up less than 5%, 75 bytes lets say.

I thought up this compression scheme in 8th grade. even then I knew there just had to be some basic problem with it.

Comment Replay of the mainframers (Score 2) 246

This could be a replay of the old days of mainframes. At more than one company, the engineers came up with mainframes on a desk, but the marketers could not see selling a desktop mainframe at the old 7-digit prices. So they just making the big boxes, til their eventual death. This happened to CDC, Data General, Digital, and Perkin-Elmer to name a few. Intel will undoubtedly survive, but it could be a long painful decline or change of direction. The "new architecture" fanatics there probably don't have much traction after the Itanium disaster.
