Google has 23 of the 48 cars on the road. Each with about 150,000 total miles or 3,450,000 total car miles. The article said 150,000 miles however based on Wikipedia Google cars had a total of 700,000 miles on cars in april of 2014. Assuming they have more cars on the road now the 150,000 miles is probably a per car number. If that is true then the expected accident rate is 3,450,000 *
.3/100000 or 10 accidents. Google has had 3, only 1 under computer control, that looks like a rate only 10% that of human drivers. So they could rightfully claim the robot cars are 10 times as safe as human drivers. To me this looks very Very good.
Why would anyone pay for the train when they will be able to ride in their self driving car with greater convenience, lower cost and almost as quick. 14 years is a long time in hardware and software development. Robotic cars (busses?) will be widely available by then. When you eliminate the idiots driving on the roads traffic will flow much better than today so travel should be faster. You will still need local transport when you get to destination city. You can rent a car or pay for a taxi both up the cost or bring your own.
Company patents expiring... Everyone can use the technology... Low cost alternatives to companies products. Company profits at risk! How to solve this? Plan: Make use of expired patents illegal. Trump up cancer causing claims to force glyphosate off market. Introduce new herbicide claim its better. Have new genetically modified seed available to work against new herbicide. Problem solved! Profits ensured for next 20 years... (just like Ozone Hole strategy it worked before...)
The ozone hole was never a real issue and is not a real issue today. One thing no one seems to point out is that ozone is formed naturally by the action of sunlight (UV) portion of the spectrum. When you get UV you get Ozone. It regenerates. The only place the Ozone hole forms is where there is no UV light. IE the poles during winter when it is dark 24 hours a day. When we looked for the first time there was a hole. My guess is that the hole has always been there and will always be there no matter what. That its size will fluxuate just like all natural things do. And yes I believe this was an industry fostered campaign to get an inexpensive widely manufactured refrigerant banned so they could force people to buy more expensive ones protected by patents.
There are 3d printer systems that cure the whole surface at once called the B9 creator. They use a DLP type projector. So that is not what is new. What is new is that that this system does not require a peel operation. In the B9creator the peel is done by sliding the platform off the newly curred part. In the Form1 the tank is peeled by pulling one side away like opening a hinged door. In this new system no peel the cured material is does not stick to the tank because of the O2 rich zone near the bottom of the tank. As the part is pulled out the next layer cures to the new projected pattern. The secret must be in how they are able to get a stable Oxygen rich zone that is not dispersed by the withdrawal of the newly cured part and does not migrate around which would seem to make the point at which curing occurs unstable.
Apparently you did not listen to the prosecutor go over the testimony in his press conference. The witnesses that testified that Mike Brown was standing with arms up either changed their testimony or their testimony was refuted by hard evidence. Many later admitted they did not even see the shooting and were just repeating what someone else said. The only credible witnesses stated Brown charged the officer who shot several times. After being hit Brown stopped and then charged again when he charged the officer the second time the officer shot several more times striking Brown in the head which instantly incapacitated him and resulted in his death. Audio caught by someone videotaping another event backs up this version of the events by the spacing and timing of the gun shots. So does blood evidence. Blood spatter was found 50 ft behind brown and 150ft from where the officer was standing. The evidence clearly showed and the credible testimony showed that the shooting was justified. What is hard to understand is why a supposedly good "kid" like Mike Brown would all of a sudden start stealing and acting like he was bullet proof.
Seems like FTDI has admitted they were bricking counterfeit parts on purpose. How would someone go about determining if their device quit working because it was bricked by FTDIs bricking driver? Is there a lawyer out there who would want to do a class action against FTDI for damaging peoples equipment? Also I do not see why FTDI would take this approach I would think they would stand to make a lot of money and gain some good will if instead they had their driver pop up a message to the user that his device had a counterfeit FTDI chip in it and offer the owner the option to join a class action suite against the equipment manufacturer by entering certain info (name address equipment make model and manufacturer ) and in return they would allow their driver to work with the counterfeit chip and share in a settlement over the counterfeit parts or they could purchase a right to use their driver for a fee equal to the chip cost ($2-$10 depending on chip) or they could choose to do neither in which case the driver would no longer work with the counterfeit chip. This strategy would help them eliminate counterfeiters or at least pay them for the right to use their software.
It does look bad, However, it is not possible to make an injection molded car body in far less time when you consider the cost and time of the tooling required. Tooling design and manufacture for a car body this size would take on the order of 12 months. The machines required to manufacture a tool this size are many millions of dollars as well as the cost of the molding machine required to mold a part that size. Once you have the tools you can spit out many high quality parts very quickly at a low price per piece. However each part is exactly the same. The real beauty of 3D printing is not the quality of the final parts its the flexibility of what you can produce. With injection molds you spend lots of money and time before you get the first part. With 3D printing you get the part immediately. You can tweak the design between each print. Or you can print something different each time. There is value in flexibility. The big challenge to making 3D printing competitive as a high volume production system is getting a high quality surface finish without increasing print time.
If you watch the video you will notice they printed the barrel with a rectangular fill density of about
In other words the barrel was mostly air! Anyone printing for strength would use a density of 1 (solid)
and a contour following fill pattern. In other words a continuous series of strong rings.
Of course they may be trying to fool bad guys into not trying this. However it does understate the
performance capability of 3D printed weapons.
So what data are they using to compare to the current data to determine this is caused by man's actions? The data they have is only a few years worth hardly enough to draw conclusions about effects that happen on a geologic time frame. They even state that the snow pack pushes the mountains down in winter and then as it melts it rises up again. Sounds natural to me and absolutely nothing to do with mans actions.. The other trend is a general uplift thats out pacing the seasonal variations. They say it tracks water withdraw "in their model". This is another example of a model that is unpublished and therefore untestable being used to draw conclusions. The article does say that tecktonic forces may be involved and it is controversial.
I went a little crazy and got 3 through Kickstarter. I use them mostly as a hobby and as a tool to create prototypes of my ideas. Currently almost done printing new Tiki Torches. The bamboo ones are falling apart however the electronic solar powered LEDs still work. By designing my own I was able to add features to keep the wasps from building nests in them. One thing the bamboo torches seemed to attract. The cost will actually be less in materials than buying new ones. Considering my time the cost is way more however its been a fun and useful project that I can show off to others. There are many future project I plan to use them for. With the 3D printers now it is possible to realize my ideas with little out of pocket expense. I plan on using them to keep me busy after retirement.
The plane was stolen not hijacked or used to commit suicide . If it was hijacked someone would be making demands for the safe return of the passengers. If it was used to commit suicide it would have been crashed and we would have found wreckage. Neither of these have occurred so the only other possibility is someone wanted the plane intact for some purpose. Who would need a plane that size with that range? Who has used planes as weapons? My guess is that the plane was taken by Al Qaeda and flown to Pakistan. It is being loaded with a nuclear bomb from Pakistan, North Korea or a dirty bomb with Soviet nuclear material. There are factions in Pakistan that are still very angry about us taking out Osama bin Laden and would cooperate in striking the US. North Korea recently detonated a test bomb so they have the technology. There is a risk that Soviet nuclear materials have made it onto the black market. The plane has a range of 8861 miles which puts London, New York or DC well within range from Pakistan. All they would need to do is shadow a commercial flight right into the target area. If I lived in any of the possible target cities I would take a vacation.
Population is growing too fast millions will starve. The world is getting colder we'll all freeze. We will use up all the oil and civilization will crash. Drug resistant germs will wipe us out. Global warming will melt the ice caps and flood the coasts. This is all crap. The world is more prosperous and healthy and clean today than 100 years ago. These doom and gloom predictions are a result of linear status quo thinking. We live in a nonlinear world full of innovation. When a problem presents itself and begins to have economic and social impact we find a solution and fix the problem. The energy problem will eventually be solved by solar and renewables (Cyanobacteria). The water problem will be solved through desalination perhaps using graphene membranes. Life will be extended and diseases will be conquered. We will move out into space. Our children will live longer in a better world than we have. They will face challenges however they are so interconnected so smart with the knowledge of the world at their fingertips they will survive and prosper.
At one time I believed that the space elevator was the only way we would ever be able to move into space on an economic basis. All rocket based methods were just too expensive. That was until I read what Elon Musk had to say about it http://www.spacex.com/news/201.... The real reason that space exploration is expensive is that we throw away the spacecraft after a single use not the fuel used to get there. Space elevators are very energy efficient and would have great longevity, however, the practical and economic problems of building a 30,000 mile long cable is vastly larger than the problems of solving reusability of spacecraft. SpaceX is well on the way to solving the reusability problem. They have a practical road map and are executing it in spectacular fashion. They have already tested and proven vertical rocket powered landing technology and on their next Space Station resupply mission they will be testing booster landing leg deployment and engine restart to try and achieve a soft splashdown in the ocean. There last attempt of restart was successful however the descent became unstable and they had to abort. It is believed that the landing legs will provide extra aerodynamic stability allowing for a successful soft splashdown. I believe it is only a matter of a few years until they have a fully reusable system. This innovation will drive down the cost of space travel by a factor of 100. In 10 years the average upper middle class American will be able to afford a vacation in space. Travel to Mars will still be expensive but not unattainable for many.
