Comment Re:Whats the hold up (Score 1) 177

None of which is worth the cost of retrieval.

Except for one thing. If you want to build an infrastructure in space, getting materials off the moon is far cheaper than getting the same materials off Earth. If you're planning on a large enough infrastructure, spending a couple of trillion on moon mines may become the smart thing to do.

Interesting: engaging or exciting and holding the attention or curiosity.

Sure. Some of these may be "interesting" to a limited set of people, but for the most part they are about the same as the other couple of hundred planets already discovered.

There's a lot of planets out there. They were expecting to find a bunch of them. This is not news.

I'm pretty sure if there were interesting planets in the 32 they are announcing, they would have pointed them out.

Slow News Day.

Seriously, are any of these 32 new planets at all interesting? It was great that we've figured out how to detect the existence of these planets, but even the chilean team doesn't bother to single out any of them as being out of the ordinary.

Now that VASIMR technology seems to be coming of age, isn't it time to do a survey of everything within say, 20 light years to find stuff that may be potentially habitable?

The only thing that this being a "right" gets you is that if there is an ISP that services your area, they cannot refuse to connect you, the service must be reasonably priced and the connection must be at least this good 75% of the time.

This is really just establishing a legal minimum level of service than an ISP can provide in Finland.

No, you don't need the right to Internet Access to survive. You also don't need the right to vote to survive either, yet you have it. You have the right to an awful lot of things you probably know nothing about, think are entirely useless and never exercise.

Yes, you probably do. You also have the right to an electricity supply to power the computer and the right to have a house to put it in.

You also have the legal obligation to pay for the house, the computer, the electricity and the internet connection.

You do not have to avail yourself any of these rights if you don't want to.

Comment Re:Solar Thrust (Score 1) 343

I'm pretty sure they wouldn't just glue a whole bunch of solar car tops onto the Ares. The 40 pounds includes not only the solar panels but also the "carbon-fiber-and-Kevlar bodywork" and perhaps even a small section of "chrome-moly steel frame".

The point is that a 540 pound car can hit 90 miles an hour with less than 40 pounds of solar cells. The cells are not a substantial portion of the weight of the car.

Submission + - Transforming Waste Plastic into $10/Barrel Fuel (inhabitat.com)

Mike writes: "Today Washington D.C. based company Envion opened a $5 million dollar facility that they claim will be able to efficiently transform plastic waste into a source of oil-like fuel. The technology uses infra-red energy to remove hydrocarbons from plastic without the use of a catalyst, transforming 82% of the original plastic material into fuel. According to Envion, the resulting fuel can then be blended with other components, providing a source for gasoline or diesel at as low as $10 per barrel."

What exactly do you mean by "bee-sting allergy". These nanobees are filled with melittin, which may or may not be the same thing.

Interestingly, if you inject melittin you'll cause "widespread destruction of red blood cells" but these things don't. That might be because they target "growing blood vessels". Presumably, if the only areas of growing blood cells are tumors, you might be able to get away with injecting someone who is allergic.

Or, assuming your friend is allergic to melittin and not one of the other fun things in a bee string, they might end up a writhing blob of agony.

Comment Re:Costs? (Score 4, Funny) 73

Given that feathers are much less dense than water, everything else being equal it would cost more to get the feathers there since they enclosure required to contain them would be larger than the enclosure required to contain water.

Things not being equal, feathers are far more compressible than water so you could perhaps increase their density substantially.

You don't specify what condition you want the feathers in. It might be possible to just glue them to the outside of the craft, in which case there are no associated container requirements whereas the water must still be contained. In this case it's going to cost more to get the water there.

On the other hand, if the water was already in orbit it would be as ice, in which case you might be able to just glue a chunk of that to the outside of the craft.

If we're gluing random chunks of stuff to the outside of spaceships, it's probably going to come down to how much friction each material causes and what loss of material each substance would undergo due to space friction.

Submission + - Incandescent Bulbs Return to the Cutting Edge (nytimes.com)

lee1 writes: "A law in the US that is due to take effect in 2012 mandates such tough efficiency standards for lightbulbs that it has been assumed, until recently, that it would kill off the incandescent bulb. Instead, the law has become a case study of the way government regulation can inspire technical innovation. For example, new incandescent technology from Philips, that seals the traditional filament inside a small capsule (that itself is contained within the familiar bulb). The capsule has a coating that reflects heat back to the filament, where it is partially converted to light. The sophisticated ($5.00) bulbs are about 30% more efficient than the old-fashioned ($0.25) kind, and should last about three times as long. So they are less economical than compact fluorescents, but should emit a more pleasing spectrum, not contain mercury, and, one supposes, present the utility company with a more desirable power factor."

Submission + - SPAM: Physical reality of string theory demonstrated

FiReaNGeL writes: "String theory has come under fire in recent years. Promises have been made that have not been lived up to. Leiden theoretical physicists have now for the first time used string theory to describe a physical phenomenon. Their discovery has been reported in Science Express. 'This is superb. I have never experienced such euphoria.' Jan Zaanen makes no attempt to hide his enthusiasm. Together with Mihailo Cubrovic and Koenraad Schalm, he has successfully managed to shed light on a previously unexplained natural phenomeon using the mathematics of string theory: the quantum-critical state of electrons. This special state occurs in a material just before it becomes super-conductive at high temperature. Zaanen describes the quantum-critical state as a 'quantum soup', whereby the electrons form a collective independent of distances, where the electrons exhibit the same behaviour at small quantum mechanical scale or at macroscopic human scale."

Submission + - Planet-forming Disk Discovered Orbiting Twin Suns (takefreetime.com) 1

slreboy writes: "Astronomers have announced that a sequence of images collected with the Smithsonian's Submillimeter Array (SMA) clearly reveals the presence of a rotating molecular disk orbiting the young binary star system V4046 Sagittarii. The SMA images provide an unusually vivid snapshot of the process of formation of giant planets, comets, and Pluto-like bodies. The results also confirm that such objects may just as easily form around double stars as around single stars like our Sun..."
