Comment This story repeats a stupid fallacy (Score 1) 330

"... white light is a mixture of colored rays that can be recombined with a lens".

White light splits into colors because of dispersion in the prism. Passing dispersed rays through another prism just disperses them more, it does not recombine them. This fallacy is famously repeated in public school science textbook diagrams of paired prisms. Newton never performed any such demonstration. He was able to demonstrate recombination in Opticks, but with something much more complicated than a pair of prisms.

Comment "Neutrality" is a phony, lying term (Score 1) 702

"Net neutrality" consists of government force applied to private entities to coerce certain behavior that would not occur freely.

Like any government "regulation", as the liberal fantasy wants to label all such schemes, ultimately it comes down to, "you and your network assets do what we say, not as you like, or men with guns will come and make you."

Comment Repeat after me (Score 1) 117

Beware the "radiant heat" fallacy.

The solar flux consists of electromagnetic radiation. Electromagnetic radiation is not heat. The sun does not radiate heat.

This novelty looks remarkably like just adding a thermocouple, which has never been any good at turning heat into electricity.

Comment Absurd (Score 1) 316

That's a ridiculous cost of 12 euros per watt, which is about 100 times the cost of a conventional power plant.

5 MW times 10 hours/day (?) is worth about 2500 euros/day wholesale.

So basically you have invested EU 60 million to earn EU 2500 per day, for a gross ROI of 1.5 percent, before expenses and depreciation.

Which is to say, this thing will have earned back its carbon cost in about 100 years.

This must be a very durable plant, what with the MOLTEN SODIUM CHLORIDE and all.

... Even in my living room, watching a Bluray at 1080p, I still see the pixels from 10-12 feet away on the couch.

Liar.

Human visual acuity resolves about 1 minute of arc. 1080p on a 55 inch HDTV is about 40 pixels/inch, which is about 40 seconds of arc per pixel from 10 feet away.

You might be seeing coarser pixelation such as compression artifacts, but not the actual pixels.

Comment My simple interview question. (Score 1) 441

I ask how you would solve Jumble puzzles from the newspaper, given a vocabulary text file. Exhaustive search is not the answer, but given that the glut of CPU power and storage has fostered brute-force approaches to everything, this is surprisingly a quite common proposal.

The solution is quite obviously a hash lookup, but you would be surprised how few "programmers" come up with that.

Comment Old idea, misrepresented, tried and failed (Score 1) 128

This idea of ion bridges has been around a long time. The application here is basically misrepresented. All it is doing is replacing a small amount of commercial electric power with solar-generated potentials. But the process isn't feasible when run on commercial power, even if the power is free, so replacing the commercial power with solar (the germ of the "idea" here) is just disguising the dead horse. Reminds me of the algae gambit: the solar constant crossed by photosynthesis is dismal, so no biofuel (corn ethanol, biodiesel, etc) can possibly be effective, but if you photosynthesize with algae, the very irony of pond scum making something useful is enough to make you (briefly) forget physical limits. Notional fantasies vs genuine engineering.
