Safety Review Finds Yucca Mountain Nuclear Waste Site Was Technically Sound

QuantumPion Re:Nuclear is a dead end (160 comments)

In 75 years all of the low hanging fruit reserves will be mined out... according to current estimates that leaves 125 years of increasingly harder to get (i.e. more expensive) ore.

Then what? I guess develop the clean energy that we should be working on now.

No. Using proven fast reactor technology, we could supply 100% of the world's energy needs for 10,000 years just using the depleted uranium sitting unused in storage barrels at enrichment plants. Not to mention the huge amounts of raw uranium ore, tailings, reserves in localities that have previously banned mining, and seawater extraction. Nuclear fuel availability is purely a political and social problem, not technical.

Safety Review Finds Yucca Mountain Nuclear Waste Site Was Technically Sound

QuantumPion Re:the problem with how nuclear works in the USA (160 comments)

It also takes pressure off nuclear power companies to invest in reclamation and reprocessing technologies and frees them to simply consume fresh nuclear fissile materials without concern for their total lifespan.

While most of your post I would disagree with, this part is especially wrong. The reason why power companies do not invest in reprocessing and consume fresh fissile material is because by federal law bans it. Remember Jimmy Carter's Non-proliferation deal? Yeah.

Safety Review Finds Yucca Mountain Nuclear Waste Site Was Technically Sound

QuantumPion Re:If only it were POLITICALLY and SOCIALLY sound (160 comments)

Nuclear waste disposal isn't an engineering problem

The folks in Japan working the #4 unit of the Fukushima Daiichi plant would like to have a word with you about this. It was shut-down and defuelled before the tsunami struck, and despite this its spent fuel pool's contents blew the building apart.

You are misinformed. While the stability of the fuel pools was unknown and a concern at the time of the disaster, it was later determined that they were in fact not leaking, damaged, or in danger. No fuel in storage was compromised. The damage to Unit 4 was caused by the hydrogen explosion of Unit 2.

NVIDIA GTX 970 Specifications Corrected, Memory Pools Explained

QuantumPion Car Analogy (113 comments)

A particular high performance car has a premium 8 cylinder engine and 32 valves at 400 hp. They also sell a non-premium version which is also 8 cylinders but only 30 valves and makes 350 hp but is a lot cheaper. The difference is that one cylinder is missing two valves which lowers its maximum power compared to the premium version. The engine's computer correctly controls the engine to compensate for the one weird cylinder, but someone in the marketing department sold the car as having 32 valves when it only had 30. The 350 hp figure is accurate, but some people complain because if they reprogram the engine control chip to force the one 2-valve cylinder to run at the same conditions as the other 4-valve cylinders, the car only makes 300 hp. But in all normal circumstances the car performs as advertised, only it was initially sold with incorrect details as to how the engine was put together to make it nearly as fast for much cheaper than the premium version.

Gunmen Kill 12, Wound 7 At French Magazine HQ

QuantumPion Re:islam (1350 comments)

Compare that to Saladin who showed mercy and the let the Crusaders go (for the most part).

Sounds like you are taking the Hollywood version of events a bit too seriously. The only Crusaders that Saladin let go were the wealthy nobles who could afford to pay ransom. Everyone else was screwed.

Physicist Kip Thorne On the Physics of "Interstellar"

QuantumPion Re:Inconsistent fuel? (289 comments)

The Endurance itself was large and heavy and full of fuel, requiring a large rocket to get to orbit.

The Ranger was a small, lightweight spaceplane which probably used something like a SABRE engine.

Here is a delta-V map of the solar system. According to it, you would need 6300 m/s delta-V to return to Earth from Mars. Which is about 2/3 the delta-V required to get to Earth orbit.

Ask Slashdot: Why Is the Power Grid So Crummy In So Many Places?

QuantumPion Re:The Internet answer (516 comments)

The reason why no one switches energy providers whom put their cables underground because if such a utility did exist, its electric prices would be much higher and almost everyone would chose the cheaper, slightly less reliable option and drive them out of business. The problem isn't capitalism. The problem is people like low prices and our current system is good enough not to warrant voluntarily paying more.

Ask Slashdot: Why Is the Power Grid So Crummy In So Many Places?

QuantumPion Re: Market forces don't work on essential utilitie (516 comments)

On the contrary, market forces work fine. The problem is simply a case of the leaky roof problem. You can't fix the roof it when it's raining, and when it's not raining there is no need to fix it because it isn't raining. When people's lights are on and working it's hard to convince them to voluntarily pay more to upgrade transmission systems.

Halting Problem Proves That Lethal Robots Cannot Correctly Decide To Kill Humans

QuantumPion Kill Limit (335 comments)

Just make sure the killbots are programmed with a pre-set kill limit. If anything ever goes wrong, all we have to do is send waves after waves of our own men at them them until they reach said limit and shut themselves down.

Apple Edits iPhone 6's Protruding Camera Out of Official Photos

QuantumPion Re:Ehhh, cases. (425 comments)

The thinner you make the phone, the thinner it will be even with a case on. And since the camera has to have a cut-out for it anyway, it makes no difference unless you are using the phone without any case.

Using Wearable Tech To Track Gun Use

QuantumPion Easier and better solution (264 comments)

Why not just add a small camera attachment to the gun (i.e. on a picatinny rail where flashlights are commonly mounted) and have it automatically activate whenever the gun is held? Seems simple, cost effective, and would show exactly when and what is being aimed at and what was happening.

UN Study Shows Record-High Increases For Atmospheric CO2 In 2013

QuantumPion Testable Prediction (427 comments)

On the global scale, the amount of CO2 in the atmosphere reached 396.0 parts per million in 2013. The atmospheric increase of CO2 from 2012 to 2013 was 2.9 parts per million, which is the largest annual increase for the period 1984-2013. Concentrations of CO2 are subject to seasonal and regional fluctuations. At the current rate of increase, the global annual average CO2 concentration is set to cross the symbolic 400 parts per million threshold in 2015 or 2016.

Oh good, they actually have a testable quantifiable prediction that CO2 will continue to increase at the same rate and exceed 400 ppm in the next two years. If their prediction proves to be correct that will lend credibility to their models. But if CO2 does not do this, will they admit they don't know what exactly is going on with the environment? Or will they still claim that the less than expected raise in CO2 is also proof of climate change due to some previously undisclosed factor?

Astronomers Find What May Be the Closest Exoplanet So Far

QuantumPion Re:Time to travel 11 light years (89 comments)

Try plugging your trip into the Tsiolkovsky rocket equation. Assume the most theoretically advanced engine exhaust velocity. What is the required initial mass for your rocket? How many multiples of the mass of the entire universe are required for your rocket?

Nothing will change most likely.

Sure they will. They will quickly be replaced with an improved model, generating large profits and campaign contributions for all involved, just like in the broken window parable. Everybody wins!

If Fusion Is the Answer, We Need To Do It Quickly

QuantumPion Re: Fusion Confusion (305 comments)

Despite having spent billions (22 Billion USD on hot fusion research by US alone) on the problem so far, with billions yet to come, we do not have working fusion reactors. Even ITER will just be a prototype with no power generation at all. Cost to develop commercially, unknown but bound to be a lot of money.

Despite $10 billion spent on the Large Hadron Collider, we have yet to see any production of commercially useful quantities of antimatter. Therefore, the LHC is a boondoggle waste of money and a failure.

San Onofre Nuclear Power Plant Dismantling Will Cost $4.4 Billion, Take 20 Years

QuantumPion Re:Cost to dismantle vs fix (343 comments)

These aren't just some random leaky pipes. We're talking about both steam generators, on both units. What happened was the old steam generators were at the end of their design life, so they were replaced with what was supposed to be like-for-like replacement. It turned out the new ones had a design flaw which caused the tubes resonate and vibrate, causing damage early on. The original cost of the steam generators was nearly $1 billion. While they could get new steam generators, it would probably take at least two years to have them made and installed. The lost generation during that time, combined with all sorts of regulatory costs, would be too much to make it worth it.

iFixit Takes Apart the Oculus Rift DK2, Finds Galaxy Note 3 Display Inside

QuantumPion Re:Got mine 2 days ago. (57 comments)

This is very true indeed. I've had tons of fun playing flight simulators Elite Dangerous and DSC. The games where you have to move around in first person make me a little dizzy, especially when turning. I really wish there was a way to adjust the speed at which you turn, or implement some method of making walking feel more natural. Anyway, I also tried out a roller coaster demo, and that nearly made me sick after about 6 seconds. Simulator sickness, due to lack of IRL g-forces, is a very, very strange feeling

35% of American Adults Have Debt 'In Collections'

QuantumPion Re:medical services need a billing time limit (570 comments)

Because in America we have two groups of people - those that think they have a right to be provided unlimited health care for free at someone else's expense, and those that think health care is a service like any other that should be paid for by the consumer. The mess we have now is a result of government trying to please both groups simultaneously.

Obama's EPA Makes A Rad Decision

QuantumPion QuantumPion writes  |  about a year and a half ago

QuantumPion (805098) writes "The Environmental Protection Agency released draft guidelines last month that could significantly relax radiation hazard standards in the case of a radiological event in the United States by using risk-based decisions.

“Think of it this way. The situations covered by these new guidelines are similar to someone dying of thirst who has the chance to drink fresh water having 2,000 pCi per gallon of radium in it. While the safe drinking water levels are 20 pCi/gal for Ra, 2,000 pCi/gal is of no threat, especially if you’re going to die from imminent dehydration. Of course, a bag of potato chips has 3,500 picocuries, so go figure.”"
