Solar Plant Sets Birds On Fire As They Fly Overhead

Dorianny Re:Drop solar heat for direct conversion (89 comments)

Solar to heat to mechanical to electricity as already reached its maximum efficiency.

Photovoltaic has still many recent discoveries for great efficiency improvements, and more are likely to come.

Using heat for conversion is degrading the energy to its worst and less usable form, direct conversion is the way to go. Halting those heat projects is good news.

The big advantage heat-conversion plants have is that you can heat slow cooling material such as salt which can continue production electricity long after the sun has set, effectively turning it into a electricity storage medium. The big problem large scale use of Photovoltaic has, is that we do not have a cheap and scalable way to store generated electricity for use when needed, not just when the sun is shining.

Next time my kids ask for food, I will take them to South Sudan to witness starvation instead. I am sure that will cure them of hunger!

UCSD To Test Safety of Spinal Stem Cell Injection

Dorianny Re:Another Trade Vanishes (43 comments)

That super expensive Hep C medicine has shown that you can have an overpriced miracle cure and make a ton of money.

What they demonstrated is that by overpricing a miracle cure you can effectively limit its use and keep it from lowering the the infection rates, thereby safeguarding the drugs future profits, all while making insane amounts of profit.

UCSD To Test Safety of Spinal Stem Cell Injection

Dorianny Fingers crossed (43 comments)

Lets hope this trial ends better than that of the poor woman who had tissue containing olfactory stem cells taken from her nose and implanted in her spine, and 8 years later had to have surgery to remove the nose that grew on her back!

Entire South Korean Space Programme Shuts Down As Sole Astronaut Quits

Dorianny "matter of national pride " (186 comments)

The whole trip was a "matter of national pride " and little more than a PR stunt in response to China's space program. She spent 11 days on the ISS on what amounts to space tourism, the average stay for real astronauts is 2-7 months. After returning to earth her job has been little more than to be paraded around and to give speeches.

Where are the Flying Cars? (Video; Part One of Two)

Dorianny back to the future (107 comments)

The only "flying cars" possible today are airplane-automobile hybrids that can get neither the driving nor the flying right. In the 50's and 60's the promise of science seemed unlimited, discoveries that would lead to a entire new method of flying, not relying on lift and drag, seemed not only possible but just around the corner. 50+ years later we still don't have a quantum theory of gravity and the mystery has only deepened.

Floridian (and Southern) Governmental Regulations Are Unfriendly To Solar Power

Dorianny Re:Yeah, whatever. (306 comments)

Unfortunately rooftop mounted solar power on private residences is just a "feel good about doing your part" project that only makes sense to homeowners thank to generous subsidies but unfortunately really doesn't make any economic sense at all when it comes to it being part of the replacing fossil fuels solution.

Long-Wave Radar Can Take the Stealth From Stealth Technology

Dorianny Re:Might cause a re-thinking of the F-35 (275 comments)

It won't. The F35 is the classic "it tries to do 255 things, so it does none of them well" thing. It needed rethinking for all sort of other reasons already, but by now it has too much political inertia. You'd have to get too many people to admit they made a mistake.

Everyone seems to not understand that that's exactly what the F35 requirements were. Unlike previous so called multi-role aircraft, which typically were designed for the Air Force and then poorly adapted to other roles, the F35 is a true Swiss army knife. The criticism seems to be heaviest for the Air Force version, probably because as I mentioned, multi-roles it replaces were initially designed for them. It cannot take on air-superiority fighters in combat, penetrate or evade advanced air defenses but that is not its role, we have specialized fighters and bombers to do that. The role I see for the Air Force F35 is to support the specialized aircraft, mop up remnants and to take over as front line fighter only when air superiority is achieved. It seems terribly expensive for that role now, but this is a Aircraft that's being designed to have the largest and longest production run in history.

With Chinese Investment, Nicaraguan Passage Could Dwarf Panama Canal

Why is everyone saying the Chinese? The only Chinese that seems to be involved in this project is Wang Jing, there is no information on this project being backed by the Chinese government.

Idiot Leaves Driver's Seat In Self-Driving Infiniti, On the Highway

Dorianny Re:Wait you want me to drive? (406 comments)

I really don't understand the need of having the human ready to take over in a emergency.

Because the "emergencies" that an autonomous vehicle will have will mostly be created by the autonomous vehicle system itself. Like not correctly detecting a small human darting into the street ahead of it

Small unexpected objects in peripheral vision requiring split second reaction time is just the sort of emergency humans are really terrible at, and at which sensors and computer systems excel at.

coming to a halt in the middle of traffic because it lost communication with a critical sensor, etc. And because the computer, no matter how well programmed by the smartest people in the room, will not have covered every contingency that could pop up in real life. Humans are just more adaptable than fixed-programmed computers.

Humans are very adaptable however the most important need for directing a single purpose automobile is choosing the right response and executing in a correct manner, and doing it all as quickly as possible, sensors and computerized systems excel at that.

Yeah, humans fail. We understand. Computers fail, too, which is something that the autonomous vehicle proponents tend to forget. And hyping the perfection of a system that is not yet in existence and hasn't been tested at full scale is how the material in Risks Digest gets created.

Everyone seems to understand that human error is responsible for most road casualties but we will not trust a computer replacement system unless its proven completely infallible. Wouldn't it start saving lives even if it was just much less error prone than humans?

Idiot Leaves Driver's Seat In Self-Driving Infiniti, On the Highway

Dorianny Wait you want me to drive? (406 comments)

Most people receive no training and have no knowledge or skills on what to do in a emergency situation. Autonomous driving itself is being developed from technologies that were first developed to take over for the human in emergencies. I really don't understand the need of having the human ready to take over in a emergency.

The Man Who Invented the 26th Dimension

Dorianny String theory is not a waste of resources! (259 comments)

String theory was devised as a mathematical model that seems to describe a workable universe which may, or may NOT be our universe. Problem is that we know that the Standard Model cannot be the complete picture but so far we have no experimental data to use as a starting point to figure out what lies behind it. When we finally do get a hint of new physics some of the new math being invented by String Theorists is going to be very useful weather or not String Theory itself correctly describes our universe.

Researchers Find Evidence of How Higgs Particle Imparts Mass

Dorianny As usual, the title is wrong! (91 comments)

The Higgs field imparts mass on particles by exchanging virtual Higgs particles with them. A real Higgs particle surfaces when the field becomes excited, but you need a lot of energy for that.

After NSA Spying Flap, Germany Asks CIA Station Chief to Depart

Dorianny Re:I found this article to be more informative (219 comments)

The Gestapo actually wasn't that good at spying. The German people were, however, quite good at turning their neighbors in to the Gestapo. There's a lot of myth concerning the Nazi police force. It's unfortunate that even today people repeat it without thinking.

I lived under a communist regime with a gestapo like secret police. It is quite true that everyone spied on everyone else but that was because of fear and intimidation tactics used by the regime. They didn't simply punish whoever they though was a threat to them, family, friends even neighbors if not sent to interment camps outright, would be punished with difficult jobs in far away regions, denied schooling and all kinds of other punitive measures. The only way to escape this fate was for them to be convinced that you already told them everything you knew. As someone with what they called a "unclean biography" because of a great uncle that had immigrated to the United States, I know full well how much suffering a totalitarian state can impose without the use of imprisonment.

Police Recording Confirms NYPD Flew At a Drone and Never Feared Crashing

Dorianny Re:So (310 comments)

What they did amounts to nothing less than arresting someone on "Trumped-up Charges". Considering all the media attention this is getting you can bet that Internal affairs is going to take this very seriously. In our system of checks and balances the judiciary and the free press are responsible for keeping law enforcement honest and in this case the press cam thru. The system works, sometimes!

After NSA Spying Flap, Germany Asks CIA Station Chief to Depart

Dorianny Re:I found this article to be more informative (219 comments)

I'd prefer a more proactive response, maybe carry around a bunch of WWII concentration camp photos and wave those around whenever the Germans complain about "spying."

No they shouldn't be punished forever, but we probably should keep an eye on them forever.

Their history with the Nazi state and the Gestapo secret police is exactly why Germans are so bothered by spying. They know for a fact that gathered information can easily be put to nefarious use.

After NSA Spying Flap, Germany Asks CIA Station Chief to Depart

Dorianny Re:I found this article to be more informative (219 comments)

The USA's response has been something along the lines of "you expected us not to conducting traditional spying activities?"

The USA rejected the proposed no spy agreement so the response is more along the lines of: We do not fully trust you and we will keep on spying on you not matter how much it annoys you.

After NSA Spying Flap, Germany Asks CIA Station Chief to Depart

Dorianny Re:Why is Obama doing this . . . ? (219 comments)

Like all large organizations, bureaucracies are hard to change and are resistant to political direction, which makes them difficult to control from the executive, but a determined and capable president can ultimately impose his will on them.

Study: Global Warming Solvable If Fossil Fuel Subsidies Given To Clean Energy

Dorianny Re:How about (385 comments)

You are absolutely correct. Many countries heavily subsidize fossil fuels by selling them domestically at below international market price. These type of subsidies cannot be easily shifted toward renewables, if they could be shifted at all.

U.S. will not provide financing for new International Coal-Fired Power Plants

Dorianny Dorianny writes  |  about 10 months ago

Dorianny (1847922) writes "The Treasury Department declared it would no longer support any new coal-fired power plants around the world. By leading a coalition of like-minded countries including several European ones that have already announced similar intentions, they will effectively be able to block the World Bank and other international development banks from providing financing for new coal-fired plants. The policy is unlikely to amount to any real change as 75 percent of proposed coal-powered plants are in China and India, which do not rely on outside financing. It seems to me that the poorest, most underdeveloped nations that contribute the least to global emissions are the ones getting the short end of the stick from this policy."

Talking on the phone while driving not so dangerous after all

Dorianny Dorianny writes  |  1 year,11 days

Dorianny (1847922) writes "New research which takes advantage of the increase in cell phone use after 9pm due to the popularety of "free nights and weekends" plans showed no corresponding increase in crash rates. Additionally, the researchers analyzed the effects of legislation banning cellphone use, enacted in several states, and similarly found that the legislation had no effect on the crash rate. "One thought is that drivers may compensate for the distraction of cellphone use by selectively deciding when to make a call or consciously driving more carefully during a call" Score this a -1 for common sense."

Europe needs genetically engineered crops, scientists say

Dorianny Dorianny writes  |  about a year ago

Dorianny (1847922) writes ""Failing such a change, ultimately the EU will become almost entirely dependent on the outside world for food and feed and scientific progress, ironically because the outside world has embraced the technology which is so unpopular in Europe, realizing this is the only way to achieve sustainable agriculture," said Paul Christou of the University of Lleida-Agrotecnio Center and Institució Catalana de Recerca i Estudis Avançats in Spain."
