Researchers Claim a Few Cat Videos Per Day Helps Keep the Doctor Away 59 59

bigwophh writes: A study published in the journal Computers in Human Behavior suggests that watching videos of cats may be good for your health. The study pinged nearly 7,000 people and asked them how viewing cat videos affected their moods. Of those surveyed, over a third (36 percent) described themselves as a "cat person" and nearly two-thirds (60 percent) said they have an affinity for both dogs and cats. Survey subjects noted less tendencies towards feeling anxious, sad, or annoyed after watching cat videos, including times when they viewed the videos while at work or trying to study. They also reported feeling more energetic and more positive afterwards. There may have been some guilt from putting off work or studying to watch Internet videos, but the amusement they got from seeing the antics of cats more than made up for it.

Comment: How will you enable long distance EVs? (Score 1) 229 229

Tesla has invested a lot of capital in building a comprehensive network with banks of superchargers capable of providing 135kW to make long distance EV travel possible. Lacking such a network other manufacturers are currently limited to producing limited range city EVs and plug-in hybrids.

Most Chademo and sae+combo chargers max out at 50kW and offer power for just 1-2 vehicles at charging locations are poorly located for interstate travel.

How will GM work to enable long distance EV travel with their vehicles?

ps: I live in Wisconsin where Tesla will soon have 9 supercharging stations, I take delivery of my Model S 85D in two weeks.

Comment: Re:Boeing bought more politicians. (Score 1) 127 127

Leaving out Boeing would be budget suicide for NASA.

No one should be left out because there should be no contract. Instead, NASA should be fostering a spot market for launches. They should have a separate bid for each launch: "We want X satellite in Y orbit, and insured for Z dollars." Then give the launch to the lowest bidder. That way each company can work continuously to cut costs and improve services, knowing that if they leapfrog the competition, they can win the next launch, instead of being locked out for years.

That is not feesable. It take years to be trained to fly in a spaceship - whether the lifting body like the Shuttle or Dream Chaser, or a capsule such as Soyuz, CST-100, or Dragon V2. You have to build not only the rocket, but a tower to carry the crew to the top of the rocket along with an arm to get the astronauts into the vehicle (which is not compatible/spacecraft). Escape systems need to be installed. It's very expensive, and it would never be built without assurance that the demand is there. At this time, there is no market for launches except from NASA or ESA. Cosmonauts would ride Russian spacecraft, Indians and Chinese are developing their own systems, etc. The public demand is too little at this time. Without a long-term contract, NASA is not enough for your proposal.

Comment: 20kW is not fast enough (Score 3, Informative) 49 49

Tesla superchargers charge at 120kW with a wired connection. 20kW is not fast enough to quickly charge an electric vehicle that has enough batteries to provide adequate range. Even the Fast DC chademo chargers for the leaf can charge at 50kW.

Fast wireless charging will never happen because wasting 10% of your power as heat under the vehicle will cause things to melt at high power rates.

As a fellow TSLA stock holder, I absolutely agree.

The growing electric vehicle market has plenty of room for multiple manufacturers. Tesla by itself cannot grow faster without introducing quality issues and cannot make vehicles fast enough to transition the entire vehicle market. Other automakers are unwilling to invest in their own supercharger network and without access to high power fast charging they will be forced to produce plug-in hybrids for the foreseeable future. Opening the standard would help bring in more capital to build the supercharger network and hasten the transition to zero emission vehicles.

Comment: Re:Putin actually speaks the truth (Score 1) 396 396

Indeed! Russia also requires all telcoms and ISPs, at their expense, to install monitoring equipment of the internet and telephones, This project is called SORM (wikipedia entry for SORM). The system was put into place around 1996-2000, but it has been used as recently as the Winter Olympics (source). It is explicitly a mass-surveillance system, so either Putin is lying or he is bending the truth: Russia doesn't pay for it... but by law the telcoms have to pay it. They don't do illegal wiretapping because it is explicitly legal. And you're right, they might not have the ability to store all that data for long periods of time, but you can be sure they are targeting people. And you can be sure they are targeting foreign governments too (of course). Heck, there were several diplomatic leaks at the beginning of the Crimean crises in order to strain US-EU ties. You can be sure that's due to Russia's intelligence services.

I think that over a certain speed, fuel economy goes way down.

This is because:
For high velocities drag will vary as the square of velocity. Thus, the resultant power needed to overcome this drag will vary as the cube of velocity. The standard equation for drag is one half the coefficient of drag multiplied by the fluid mass density, the cross sectional area of the specified item, and the square of the velocity.

Windfarm Sickness Spreads By Word of Mouth 482 482

eldavojohn writes "Just like the many stories surrounding alleged 'Wi-Fi sickness,' research is now showing that windfarm sickness spreads by word of mouth instead of applying universally to windfarms. Areas that had never had any noise or health complaints were suddenly experiencing them after 2009 when anti-wind groups targeted populations surrounding windfarms. From the article, 'Eighteen reviews of the research literature on wind turbines and health published since 2003 had all reached the broad conclusion that there was very little evidence they were directly harmful to health.' While there's unfortunately no way to prove that someone is lying about how they feel, it's likely a mixture of confirmation bias, psychosomatic response, hypochondria, greed and hatred of seeing windmills on the horizon that drives this phenomenon."

Apple Kills a Kickstarter Project - Updated 471 471

Nerdfest writes "Venturebeat is reporting that a successfully funded Kickstarter project for a portable phone charger that works with both Apple and Android devices has been canceled because Apple wouldn't let the creators license its Lightning connector. Quoting: 'Edison Junior, the technology and design lab behind the POP portable power station, is returning the full $139,170 in funding it received from Kickstarter backers to develop the device. Unfortunately, Apple has refused to give the project permission to license the Lightning charger in a device that includes multiple charging options. ... "We didn’t get a yes or a no up front," Siminoff said. "But as we kept going back and forth it was clear that it was getting harder. Then, when we saw that they weren’t even going to allow a Lightning connector and a 30-pin connector together, we knew it was over." He also said that, while Apple is a private company and can do whatever it wishes, it should watch out. "When you do things that are bad for the customer I think it will be bad for them.”''" Update: 12/21 22:16 GMT by S : Apple has relented. A spokesman for the company told Ars, "Our technical specifications provide clear guidelines for developing accessories and they are available to MFi licensees for free. We support accessories that integrate USB and Lightning connectors, but there were technical issues that prevented accessories from integrating 30-pin and Lightning connectors so our guidelines did not allow this. We have been working to resolve this and have updated our guidelines to allow accessories to integrate both 30-pin and Lightning connectors to support charging."

Facebook Changes Privacy Policies, Scraps User Voting 119 119

Orome1 writes "The voting period for the proposed changes to Facebook's Statement of Rights and Responsibilities and Data Use Policy has ended on Monday, and despite the email sent out to the users asking them to review the changes and cast their vote, less than one percent of all users have done so. 'An external auditor has reviewed and confirmed the final results. Of the 668,872 people who voted, 589,141 recommended we keep our existing SRR and Data Use Policy,' stated Elliot Schrage, Facebook's vice president of communications, public policy, and marketing. Still, that is not nearly enough to prevent the proposed changes — as required by Facebook, at least 30 percent of the users should have voted against them in order to keep the previous versions of the policies. Schrage pointed out that that the whole experience illustrated the clear value of Facebook's notice and comment process."

Advertising May Soon Follow You From One Device To the Next 132 132

moon_unit2 writes "We're all familiar with ads that seem to follow you around as you go from one website to another. A startup called Drawbridge has developed technology that could let those ads follow you even when you pick up a smartphone or tablet. The company, founded by an ex-Google scientist, employs statistical methods to try to match and identify users on different devices. The idea is that this will preserve privacy while making mobile ads more lucrative, although some experts aren't convinced that the data will be truly anonymous."

There is very little future in being right when your boss is wrong.
