Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days

GPS Pilot Mass delta doesn't bring much to the table (975 comments)

Yep, I'd love to see a dozen more labs replicate this finding.

Now, you are demanding that investigators look for a picogram-level mass delta. But really, how much proof would that add; isn't it much easier to fake a tiny mass delta than to fake an overwhelming shift from Nickel-58/Nickel-60 to Nickel-62?

How Nigeria Stopped Ebola

GPS Pilot Whoa, not aspirin (381 comments)

after a few ICU places and a few quarantine beds, modern medicine is left with aspirin and electrolytes as far as 'treatment' goes which doesn't give us much edge on African medicine.

Probably not a good idea to mention aspirin in conjunction with Ebola treatment. Ebola patients suffer from decreased blood clotting and internal and external bleeding. Aspirin, a blood thinner, would exacerbate that situation.

Is It Time To Throw Out the College Application System?

GPS Pilot Shortage? (389 comments)

The US has a huge shortage in the trades because we stopped telling high school students to go into plumbing, welding, electrical

Thanks... that explains why half the time when I turn on the faucet or the light switch, nothing happens, and the other half of the time, it only works because I've spent a large fraction of my income on maintaining those systems, due to the exorbitant wages those tradesmen are able to demand due to the shortage of those skillsets.

Oh... the previous paragraph wasn't true at all? There isn't a shortage of those skillsets?

Actually, contrary to being a shortage, demand for most kinds of workers is too low. That's why the labor participation rate just fell to a 36-year low.

Is It Time To Throw Out the College Application System?

GPS Pilot Painting worksheets with a broad brush (389 comments)

Fill out this worksheet. Nobody actually benefits from you doing this

Most of the worksheets I filled out in school benefitted me, by presenting opportunities to practice valuable skills.

If your school passed out dumb worksheets that didn't reinforce vaulable skills (see: stupid Common Core math worksheet stumps dad with PhD), your school was doing it wrong. Sorry you had to go through that.

Energy Utilities Trying To Stifle Growth of Solar Power

GPS Pilot Evidence, please (488 comments)

Those who participate in net metering are selling surplus power when they have a surplus to sell, and buying power when they don't. It's rather absurd to say the power they purchase at night is "free," when in fact every single kilowatt-hour they purchase eats into the proceeds from their daytime power sales. If they are selling power at, say, a wholesale rate of $0.02 per kilowatt-hour, and buying power at a retail rate of $0.12 per kilowatt-hour, it massively eats into the proceeds from their daytime power sales.

If you were correct that every kilowatt-hour sold by a solar facility has to be "thrown away," or discharged into the ground, then you would also be correct that that's not a sustainable business model. But you present no evidence for this. Here I present evidence to the contrary:

A utility can look at the forecast for how sunny it will be, and then conservatively scale back production at its peaking plants and at its load-following plants, to minimize the amount of solar power that needs to be "thrown away."

Energy Utilities Trying To Stifle Growth of Solar Power

GPS Pilot That's not the definition of net metering (488 comments)

Since their net use is zero, their electric bill is zero

Wrong for several reasons.

Some households that participate in net metering are net producers of power, "exporting" more than they "import." Other households have remained net consumers of power. But no household has perfectly balanced exports with imports, resulting in zero net usage.

And even if a household did happen, one month, to export exactly the same number of kilowatt-hours as it imports, the fact of net metering does not guarantee that the utility will pay retail price for the exported power. The term "net metering" also applies when a utility pays wholesale price:

Net metering policies can vary significantly by country and by state or province: if net metering is available, if and how long you can keep your banked credits, and how much the credits are worth (retail/wholesale).

It doesn't make sense that a utility should be forced to pay retail price for each tiny trickle of power generated by amateur mom-and-pop producers, when bulk power generated by professionally-managed plants can be purchased at wholesale price.

GPS Pilot Re:Catastrophe? (488 comments)

A one- or two-percent annual failure rate for such an expensive device is a financial catastrophe, at the very least.

Nope... that means it will fail, on average, every 50 - 100 years. That's a pretty good service life for any device... and if it became commonplace for households to have a flywheel, failure should be covered by homeowner's insurance, just as roof replacement is (which needs to be done every 20 - 30 years).

GPS Pilot Catastrophe? (488 comments)

a flywheel that has a distressing tendency to self-disassemble. Catastrophically.

GP did specify a buried flywheel. If pieces of flywheel become embedded in the soil four or five feet under my lawn, I fail to see the catastrophe. A one- or two-percent annual failure rate for a device like that would be quite acceptable.

GPS Pilot No magic needed (488 comments)

If everyone is doing net metering, you need a magic free energy source the other 20 hours per day.

Why, when we already have a non-magic, non-free network of generating plants? Some of them burn fossil fuels, some of them don't, but that network as a whole becomes more robust when supplemented by distributed solar power installations that produce during hours of peak demand. Brownouts become less likely, etc.

I'm not in favor of going solar when other sources are more cost-effective -- and I'm not in favor of subsidies that merely give solar the illusion of being more cost-effective. Having said that, you've built a strawman: I haven't heard anyone asking to be provided with "free" energy from the grid during hours when the sun's not shining.

GPS Pilot (1) Eliminate subsidies, (2) Solar profits (488 comments)

Allowing utilities to pass along 100% of "the fixed cost for just being hooked up" will -- in the long run, and not-so-ironically, if you think about it -- actually be good for adoption of solar power.

Because the alternative -- bankruptcy for the entities that add value to solar power installations, by maintaining the grid that ties them together and delivering power when the sun's not shining -- is not sustainable.

The utilities' current opposition to solar implies that they're being forced to provide money-losing subsidies for grid connections. Eliminate those, and everyone will benefit from the new transparency in the cost structure.

GPS Pilot Dead hand of capitalism? (488 comments)

Actually capitalism is the only thing that is encouraging Americans to install solar power systems in any significant numbers. And within my city's limits, nobody has solar because the government-owned utility forbids residents from doing business with that capitalistic company (or its competitors).

Cuba Calculates Cost of 54yr US Embargo At $1.1 Trillion

GPS Pilot No Poland-like outcome possible (540 comments)

One problem with your reasoning. Polish leaders very heartily embraced the West and NATO membership. In Cuba, on the other hand, the Castro brothers managed to hang on to power despite the economic crisis caused by the disappearance of theirr USSR sugar-daddy. If Cuba's economy had gotten a boost from the USA, the Castros would have used the additional revenue to further solidify their grip on power. I don't see a path to obtaining a Poland-like outcome, and you sure haven't pointed out such a path.

Universal Big Bang Lithium Deficit Confirmed

GPS Pilot Precision vs. accuracy (171 comments)

Another journalist misuses the word "accurately."

Astronomers can calculate quite accurately how much lithium they expect to find in the early Universe

They can calculate it quite precisely; but if the number doesn't match observations, the model is not accurate.

GPS Pilot How about sharing legitimate advice? (151 comments)

Instead of a whimsical poll, I wish slashdotters would be sharing legitimate advice about how to protect devices from EMP (either natural or man-made).

For example, if I store a hard drive or other sensitive device in a safe, can any old safe protect it, or does it have to be a safe specially designed to offer EMP protection?

Climate Damage 'Irreversible' According Leaked Climate Report

GPS Pilot Thinking outside the box yields a better solution (708 comments)

A lot of people are completely against this idea (government intrusion on freedom, etc.) but that's the only way we've ever solved problems based on the "tragedy of the commons"

Really... government coercion the only way? No one voluntarily shares their assets for the benefit of the greater good? The facts say otherwise:

"Total giving to charitable organizations was $335.17 billion in 2013 (about 2% of GDP). This is an increase of 4.4% from 2012. Although this is the fourth straight year that giving has increased, it is still not at the pre-recession level of $349.5 billion seen in 2007."

Charitable giving increases as a person's disposable income increases -- and not linearly, either: as income grows to exceed a person's basic needs, people tend to increase the percentage of income given to charity. That's why a 10x increase in GDP would result in greater than a 10x increase in charitable giving.

So if we just resume pursuing pro-growth policies for a few more decades, private charity will be more than capable of providing the entire social safety net -- bigger and better than our current social safety net -- and government will be able to streamline itself and stop performing that function. (Which will be a quite virtuous circle that has further benefits for the economy.) There is also quite a bit of value in the fact that it will be 100% funded by voluntary contributions, and 0% by coercive confiscation.

When philanthropists perceive that the social safety net is well-funded, they will shift a portion of their giving to other charitable purposes of their choosing: for example, subsidizing clean energy projects.

Remember, pursuing pro-growth policies is the key to realizing this rosy future. That means growth we come by honestly, as opposed to short-term growth that is forced by unsustainable, house-of-cards measures -- like deficit spending, or the Fed holding interest rates artificially low.

More details about Mars mystery rock

GPS Pilot GPS Pilot writes  |  about 9 months ago

GPS Pilot (3683) writes "Previous reports said the rock that suddenly appeared out of nowhere was merely 'the size of a jelly doughnut.' Now, a color image shows additional reasons for this metaphor: 'It's white around the outside, in the middle there's kind of a low spot that's dark red,' said lead scientist Steve Squyres. In the image, the object does stick out like a sore thumb amidst the surrounding orange rocks and soil. Its composition is 'like nothing we've ever seen before. It's very high in sulfur, it's very high in magnesium, it's got twice as much manganese as we've ever seen in anything on Mars.' If it's just a random rock that had been kicked into position by one of the rover's wheels, chances are it would not be 'like nothing we've ever seen before.'"

Roll your own pivoting display?

GPS Pilot (3683) writes "A monitor with 16:9 aspect ratio is perfect for watching DVDs, but perfectly wrong for word processing and coding. What's the best way to get the best of both worlds: should I pay a premium for a display that has a 90 degree pivoting feature built-in (such as the HP LP2465), or is there a good aftermarket VESA mount desktop stand that can turn any LCD into a pivoting display? And how well do various OSes support pivoting displays? (I'm most interested in OS X.)"

Fifth fundamental force of nature: antigravity?

GPS Pilot GPS Pilot writes  |  more than 6 years ago

GPS Pilot (3683) writes "Dr. Randell Mills has just posted a paper in which 'We report the experimental confirmation of 15 predicted hyperbolic-electron states that are observed forced away from the Earth with an acceleration that is over twelve orders of magnitude greater than that of gravity, as predicted.'

In other words, a fifth fundamental force of nature, which amounts to a very powerful form of antigravity.

He performed the experiment with an off-the-shelf electron gun."
