That doesn't seem like a show-stopper to me, at least not for a defensive use.

A ground-based long-wave installation could send the data to a fighter or missile using wireless technology.

If you cover your country in long-wave receiver antenni, then you've found your stealthed target and can relay its position to your fighters.

If not for a bribe (or increased public awareness/donations), then Greenpeace is doing it as a show of unearned power.

That being said, their statement is scientifically meaningless without such calculations, and if Slashdot is going to have a discussion about pollution from Amazon Fire devices, then I would like to see such a discussion have scientific meaning.

Then we can discuss politics if there even is significant scientific meaning to it.

I would like to see a calculation of how much CO2 is emitted by uploading a photo compared to, say, driving to the grocery store.

The calculation would take the CO2 emitted by powering the servers, divided by the number of users of the servers, divided by the number of photos a user is expected to upload over a given time period.

I would imagine that heating your home or driving would be much worse, and the time spent uploading the photos would be better for the environment than driving to the movies. But this is speculation until someone does the calculations.

Technically, much of the star's mass is lost when it goes supernova, so part of the original star is lost and is therefore not part of the neutron star. So, pit would be a somewhat better descriptor than husk.

Also, I've heard that a teaspoon of matter would be more mass than Manhattan Island. Wikipedia's "Neutron Star" article says, "a neutron star is so dense that one teaspoon (5 milliliters) of its material would have a mass over 5.5Ã--1012 kg (that is 1100 tonnes per 1 nanolitre), about 900 times the mass of the Great Pyramid of Giza."

I doubt that the earth is 900 times the mass of that pyramid, but yes, one teaspoon of Neutron Star is very massive.

Can you please provide a source or calculations for which you derived your "yes" answer? How do you know that it doesn't take more fossil fuels to make ethanol than are saved by using it?

Please include the fuel-costs of making the ethanol, the decrease in mileage, as well as the repair costs to engines and hoses that have been damaged by using the ethanol. Repair costs would include replacement parts or even replacement cars, as some people just junk cars rather than having them fixed once they develop enough problems. And of course it takes fossil fuels to create these replacement parts.

If you think that we're running out of work, then the solution is to enact laws that promote growth of small businesses (or refrain from enacting laws that harm those businesses).

I'm thinking specifically of Regulation D, which prevents the middle/lower class from investing in small businesses (as "Angel Investors") that need money, but aren't big enough to be listed on a major exchange. This makes it more difficult/less profitable for entrepreneurs to set up new businesses to provide more work for society to do.

In fact, most regulations on business harm small business more than large businesses. This is one reason that big business Amazon wants to enact internet sales tax; it hurts their competitors more than it hurts them, and therefore makes it easier for Amazon to compete.

It doesn't just happen in communist societies, but also in over-regulated societies as well.

Then why not say "over-regulated", instead of smearing an approach you oppose with an association with communism?

Fair enough.

I only mentioned communism because I see the US moving in that direction rapidly.

In the direction of communism, or the direction of over-regulation?

Both. By over-regulating, the US government is gaining more and more control over the means of production. For example, coal/nuclear regulations allow the government to have power over electrical generation companies. The US gained more control during the US bank bailouts (and subsequent regulation of all banks) and automotive company bailouts.

Unions also exist in a free market, and the serve the opposite effect of increasing wages. In a communist government, where businesses have ties to government, you can't piss off your boss, or you'll find yourself unemployed. Then other government-tied employers are too afraid to hire you because arbitrarily-enforced laws ensure that you're branded a criminal.

Some people believe that property rights grant them the right to spend their money how they like. People have the right not to buy internet if they desire. But if enough people decide to infringe on those {god-granted|human} rights, they will be able to pass such a law in the USA.

Probably because if we financed it, then we get the credit if it helps stop/stabilize the middle east. And it's a way we can aid an ally without incurring international strife (after all, it is solely a defensive weapon). And because a stable middle east is necessary to fuel our appetite for oil. A universal healthcare system for Israel costs so much less than one in the US, due to the number of citizens.... And in an area as volatile as the middle east, leaving sick people out to die (and spread disease and dissent) is a threat to Israel's national defense.
