Comment Not Exactly (Score 5, Informative) 116

Seeing as they specifically mention Electro-Optical and Infra-Red guided missiles, It seems that the objective is not to 'blow up' a missile as the linked article suggests, but rather to use a laser to blind the missile's tracking systems, causing it to lose tracking and veer off target or "generate a miss" as they say.

Getting a laser to destroy a missile requires about 100 kW of energy and a few tons of hardware to focus it.

Getting a laser to blind optical sensors requires a $10 Radio Shack gift card.

Comment GOLD - Asimov (Score 4, Interesting) 532

Gold! Willard was hesitating. Money, when it was a matter of electronic exchange, meant nothing.
There was no feeling of either wealth or poverty above a certain level.
The world was a matter of plastic cards and of slots and all the world transferred, transferred, transferred.
Gold was different. It had a feel. Each piece had a weight. Piled together, it had a gleaming beauty.
It was wealth one could appreciate and experience.

He didn't need the money. He was not so sure he didn't need the gold.

And potentially very profitable. Huge chunks of valuable metals floating around waiting to be mined. .

I seem to recall reading that If there were a mass of gold ingots in low Earth orbit, it would not be economically feasible to send the Space Shuttle up to bring them back to Earth. You'd spend more on training, parts, maintenance and fuel than a cargo hold full of pure bullion could offset. If you had a factory in orbit to use the gold to some purpose, that might be different, but that's putting the cart before the horse.

If it is indeed a 'garden spot' for life, we should be extra careful to not send any wayward seeds with our robotic emissaries.

"Oh, hello deep-dwelling sentient beings. Yeah, sorry about those microbes that got stuck to our probe and seem to be causing your extinction."

O The Embarrassment.

Comment An Important Distinction (Score 1) 506

Islam has never killed anyone. Islam has never detonated a suicide bomb. Islam has never called for the downfall of Western Culture. Also, Christianity has never declared a Crusade, rallied against equal rights for homosexuals or called for the killings of doctors who perform abortions.

All these things have been done by *humans* who have decided to hijack an entire religion and twist it in order to accomplish their secular goals.

Comment Solving half the problem (Score 1) 189

Instead of having a specially-made or retrofitted baton, how about having the area in front of the podium encased in a magnetic field like that of a theremin, such that the baton would provide data on horizontal position by pitch and vertical position by volume. That would give you all the data you need to feed to whatever peripheral signals the musician (come to think of it, an earbud with the output would help for the beginning of the piece, but it might be too distracting for things like tempo changes.
