Comment Re:Yet Another Terrible Flamebait Slashdot Summary (Score 4, Insightful) 757

It doesn't sound like he was 'asked', since when he refused, they forbade him the chemical. Asking implies that you have the choice to say yes OR no.

I ask my 4 year old if he'd like to go to bed, and he doesn't have a choice. That in no way diminishes the polite manner in which I ask.

I hope you don't consider the relationship of a 4 year old to a parent a good metaphor for your relationship with your government.

Unless you're in North Korea, then of course that makes sense.

Not enough data for a reasonably intelligent prediction.

-Are these 1,000 who self-assess as "reasonably intelligent", or are these 1,000 who somehow actually are selected to be reasonably intelligent?

Comment Re:Did it "confirm" it was caused by man? (Score 1) 967

Anyone who isn't an idiot knows that the earth's climate is ALWAYS changing (and always has been).

Also, earthquakes & tornadoes are totally not humanity's fault, so we shouldn't plan around them either.

90% of the response for handling global warming will look different depending on if the climate change we're observing turns out to be artificial or natural. I think the OP wasn't saying that we shouldn't plan, rather than we should confirm the cause before rushing into (possibly useless or worse) action.

Comment Re:Efficiency check (Score 1) 359

Is it really less efficient? As I understood it, the rotary engine gives an equivalent HP compared to a piston engine at a fraction of the displacement.

while burning much more fuel. Higher peak power per liter of displacement isn't the same as efficiency. A jet turbine gives far more HP compared to a rotary at a fraction of the displacement as well, doesn't make it necessarily more efficient.

If you want maximum efficiency in converting chemical energy into kinetic energy, Sterling engines are the top of the heap (with terrible power:mass or power:volume ratios). If you want maximum power to weight you want a rocket engine.

Rotary (and piston) engines are buried somewhere in the middle of the spectrum.

The Internet

Submission + - Northern Canada in the Dark (www.cbc.ca)

zentigger writes: At approximately 06:36 EDT Thursday, October 6, 2011, Anik F2 satellite experienced an attitude control issue and lost earth lock affecting C, Ku and Ka services. The satellite went into safety mode and moved from pointing to the earth to pointing to the sun.
This has put most of Northern Canada in the dark as all internet and phone services come in over F2.

Medicine

Submission + - Did Alternative Medicine Contribute to Steve Jobs' (skeptoid.com) 9

ideonexus writes: "An aspect of Steve Jobs' battle with cancer that the media has been glossing over is the fact that Jobs' spent nine months pursuing alternative therapies to treat his tumor before finally having it surgically removed as modern medicine recommended. Jobs' particular form of pancreatic cancer was very treatable and had a high survival rate, but his delay in seeking professional medical treatment moved him into the low survival rate group.

This raises the question, how could someone as wealthy and intelligent as Steve Jobs do something so foolish as to completely disregard modern medicine in treating such a life-threatening disease? And how much money did Jobs' "naturopath" make off of prescribing a clinically-unproven diet that delayed an effective treatment and dramatically reduced his chances of survival?"

Apple

Submission + - The first time I used an Apple computer was... (arstechnica.com)

jbrodkin writes: "When I saw the news that Steve Jobs had died, I thought about 1984 (give or take), when I was about 5 years old and my parents bought an Apple IIe. It was the first computer I ever used. Even as a child, I knew there was something fundamentally new and exciting going on, that this was a step forward in human capability. At the very least, typewriters suddenly were archaic. We used the Apple to write school reports and play video games. We used floppy disks to load software and save files, and sometimes when I was bored of video games I played another game called "see if you can destroy a floppy disk." After years of using Windows as an adult, Apple crept back into my life with the iPod, and never quite left. As an occasional history buff, I marvel at the impact Jobs and his competitor Bill Gates had on my life and the lives of so many others. But mostly, I remember what it was like when I first used an Apple computer. All of us technology nuts have stories like this, so I asked my colleagues to share theirs. Here's what we came up with."

You're right, it's only fair to subsidize energy from fossil fuel sources. You know, real energy.

I never said it was "only fair to subsidize energy from fossil fuel sources".

You're right though, fossil fuels (for example) are an actual energy source when compared to typical current photovoltaic solar panels which use more energy to produce than they'll generate over their lifetime (and that's before the conversion losses). The typical solar panel you see on a rooftop is really more a coal burning panel.

Nothing against research into solar energy, just when you find people deploying with current technology onto their rooftops (or window panes) and announcing their "helping the environment" or that they have a "carbon neutral" energy source or that what they're doing makes economic sense is laughable.

Normal solar panel takes 10-15 years to pay for itself

Assuming no subsidies anywhere along the production/sales/installation process making the solar panels feel artificially cheap. And not counting losses converting the electricity into 120v/Hz AC. Nor counting losses converting power to storage and back again to match energy demand that doesn't coincide with peak production. Or feeding it back into the grid where it takes at a minimum DC --> 120v 60Hz AC --> 240v 60Hz AC --> 120v 60Hz AC path with conversion losses at each step. Assuming your output from the panels at year 10 is the same as year 1.

Otherwise yes, a normal solar panel only takes 10-15 years to pay for itself.

If it only produces 20% of a normal panel it won't be worth it unless it costs about 20% of a normal panel

...or just use the usual tactic, ratchet up the subsidies a little more to further hide the underlying inefficiencies.
