  1. Mandatory outside benchmarks = on Camless Internal Combustion and the Digital Age (hackaday.com) · · Score: 1

    What it really means is that the efficiency improvements are so poor it is not worth the additional cost. Unless some government agency, for good reasons or for bad, forces the manufacturers to change it is not worth it.

  2. Most people know evolution is true. on Americans' Evolution Knowledge Isn't That Bad, If You Ask About Elephants (sciencemag.org) · · Score: 1
    I am sure most people with even smattering of knowledge and education know, deep in their heart, evolution is true, believe it must be true. But if you ask them to make a statement starkly contradicting their faith, they would rather conform to faith. Faith, is very close, personal and important to them. Evolution being true or not, asked by some distant researcher in white coat with a clip board... not so important.

    That is why religious people sponsored surveys make it sound as reactionary and iconoclastic as possible. The religious fundies know that if an escape route is offered that will let the survey respondents find a way to agree with science without very strong contradiction to their faith, they will take that option.

  4. The coal burnt in powerplants emit lots of radio active elements in the smoke and ash. Coal ash is NOT as radioactive as nuclear waste. But there is so much of coal ash and smoke, if all the radio active elements released to the environment is counted, coal plants spew as much radio active elements as the what the nuclear plants produce

    So if we add small amounts of nuclear waste, uniformly into the furnaces of coal plants, we could uniformly spread all this radio active waste all around the world. With just doubling the raioactive waste from coal power plants, we could get rid of all the nuclear waste. Spread uniformly over the surface of earth, 300,000 cubic meter will contribute 2.33e-09 cubic meter/square meter.

  8. Re:This could be really useful for docks and ferri on A New Technique Makes GPS Accurate To An Inch (gizmodo.com) · · Score: 1

    Why try to maneuver the huge vessel? A simple floating bridge with gangways manually controlled like they do with airbridges for the airplanes is even more simple. Given the mass and inertia of the ships, throwing a couple of thick ropes and tightening them automatically will adjust the floating bridge gangway to the ship.

  9. Re:Can we stop the Einstein worship now on Even Einstein Doubted His Gravitational Waves (astronomy.com) · · Score: 1

    Also let us state it correctly. Einstein did not say E= m c^2. He proved it.

  10. Who were the peer reviewers? on Even Einstein Doubted His Gravitational Waves (astronomy.com) · · Score: 2
    The unsung heroes of science are the peer reviewers. It is the peer review that gives science the feedback to stay on course. Without a strong and independent peer review there will be no difference between a philosopher, a quack, a pundit and a scientist.

    Most of the general public would not know that even Einstein's publications went through peer review and there were reviewers who checked and rejected Einstein's math. Think about it.

    Do we know the reviewers who rejected the flawed paper by Einstein? Or, are their names lost to history, without even a Tomb of the Unknown Reviewer?

    It must have happened many times before. But no one survived to tell why they drove the car at 90 mph and crashed. They just blamed the rash driver. Only when the drivers were able to call using their cell phones, it was realized what was really happening.

  12. Rick Snyder uses this research to fend off. on Study Finds You Can Grow Brain Cells Through Exercise · · Score: 1

    The administration of Gov Rick Snyder is under lot of fire for its lacklustre response to the crisis in Flint. The residents are still being asked to walk to the local fire station to pick their daily ration of water bottles. Today his spokesman vigorously pushed back claiming it is according to plan. He said, "The latest research shows aerobic exercises improve the brain cell count and the children with lead affected brains need to get all the exercise they can get to get back on track. This is how the administration is finding innovative ways to make Flint residents get adequate physical exercise".

  13. clean coal is a dead end. Re:Energy in? on Carbon Dioxide From the Air Converted Into Methanol (gizmag.com) · · Score: 2

    Dirty coal is more expensive than natural gas. Clean coal will be even more expensive and not at all competitive with natural gas. What is killing the coal industry is simple free market economics. Not EPA, not tree hugging enviro nazis, not government waging war on coal.

  14. They should also try Jedi helmet technology on Are Roads Safer With No Central White Lines? · · Score: 1
    Basically the idea is, people are driving fast because the windshield is transparent and allows them to see the road, giving them a false sense of security. This Jedi helmet technology was first demonstrated by the famous scientist Dr Obi Wan Kenobi and his graduate student Luke Skywalker back in the 1970s. Once your eyes are covered and stop overloading the brain with useless visual information, the brain will start becoming more sensitive to extra sensory perception from the Force. Further replacing glass windshields with steel will also improve the crash worthiness and improve the strength.

    So pretty soon road safety engineers will be advocating for opaque windshields, probably made of steel.

  17. I think the influence is mild on Don't Hate Perky Morning People: It Might Be Their DNA's Fault. (arstechnica.com) · · Score: 3, Interesting
    I have always enjoyed sleeping in late and had trouble staying awake in the 8am classes. But finished college and had trouble showing up for work at 8 am. When the daughter came along, I had to get up early so that I could return early and take care of her. That sort of set the habit and now I am up at 5am weekdays even when I stay up watch the election debate till 11:30. And can't stay in bed after 7 on weekends.

    I don't think I got it through DNA. Mainly circumstances and habit. If at all there was influence from DNA it is quite mild.

    If everything has already been developed, tested, proved cost effective and if they are ready to deploy it today and apply for FAA certificate, it would take 10 years before they get it. Plain documentation of what the system is, and FAA failure mode review and the maintenance and certification requirements, additional independent testing by FAA... no way they can get a hydrogen fuel cell into a passenger plane in less than 10 years.

  21. Was sleeping, in Bangalore. on 30 Years Since The Challenger Disaster: Where Were You? (space.com) · · Score: 1

    Woke up in the morning, and walked to the front door. Milkman dispensed half a liter of fresh milk from a can, groggily picked up The Indian Express, (Bangalore edition) and it was front page news with the iconic contrail picture. I was an aerospace engg grad, working for a Dept of Defense in unmanned aircraft, and was following space news well, so it was a big shock to me. Indian English newspapers do a pretty good job of covering the world and was quite to up to date. Sadly the newspapers in America proved to be a big disappointment. Nothing compared to the Science, Engg, Technology section of The Hindu (Madras edition). Even now I find Indian newspapers cover the world and America better than American papers.

  22. Electric delivery trucks have a great future on Tesla Truck 'Quite Likely,' Says Elon Musk (bgr.com) · · Score: 3, Insightful
    There are a whole range of vehicles that can switch to electric if the price is not an issue. These are not range limited vehicles.

    Most school buses, mail trucks, parcel delivery trucks, can go electric. Most of them stay close to their base station and can be charged over night. Further they are suitable for "swap-the-battery and continue" mode of operations. Deliver fleets could build battery swap stations for their trucks to swap batteries when needed.

    Currently these options are not being pursued because the price is too high for the cost savings. As gas prices fall they become even more unviable. But these are the first ones that will be peeled off when the battery price break through comes along.

  23. OK for chopper but for fixed wing airplane? on Graphene-Based Coating Could Act As a Real-time De-Icer For Aircraft (rice.edu) · · Score: 1
    1 cm thick coating of ice happens only on ground for aircraft. While flying they can not tolerate 1 cm change in the air foil shape. Especially choppers with thinner rotor cross sections. But if the parked aircraft picks up that much of an ice coating, heating the contact layer will melt that layer and debond the ice from the wings. As the chopper spins up the rotor, the airflow and other flexings will throw the ice off. Very good for choppers.

    For fixed wing aircraft they can't take off hoping airflow will shake the ice off. Most likely they might still use high pressure water hose to shake the ice loose once it has been debonded from the wings. But plain water would freeze again. So it is back to glycol? May be heating the layer of ice right next to the wing will reduce the amount of antifreeze needed to de ice the wings.

  24. Wasted ooportunity! on Discrepancy Detected In GPS Time · · Score: 2

    When the atomic clocks in GPS satellites have a discrepancy, you don't report a discrepancy. You report you have done some experiments that suggest faster than light travel across some 30 km apart in the Swiss Alps. By the time they track it down and attributed to some discrepancy in some atomic clock, you got your headlines, the 15 minutes of fame.

  25. Stop giving Goldmann Sachs ideasRe:By their logic on Stingray Case Lawyers: "Everyone Knows Cell Phones Generate Location Data" (techdirt.com) · · Score: 2

    By their own logic I should have just as easy of a time to be able to set up my own cell towers and siphon in all the location data that comes into it, and the government can't say boo about it

    Surely you jest. Even if you were serious, you probably don't have the resources to pull it off nor you may have any ideas of how to make money off this. But all it takes is someone to plant this idea in the head of some pointy haired boss in Goldman Sachs or JPMC. There are sitting on two trillion dollars of excess capital and don't know what to do with it. They might decide to do it. Atleast with the government you might get a chance to vote against it or legislate against it. But once Goldman does it, that is the end. There is nothing anyone, including Goldman can do about it.

    So stop giving them ideas.
