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

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

Posted by Soulskill
from the people-who-are-allergic-to-ideas dept.
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

Posted by Soulskill
from the there-is-but-one-way dept.
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

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

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."

Grim Picture of Polar Ice-Sheet Loss 412

Posted by Soulskill
from the i-blame-the-ice-cube-miners dept.
ananyo writes "A global team of researchers has come up with the most accurate estimate yet for melting of the polar ice sheets, ending decades of uncertainty about whether the sheets will melt further or actually gain mass in the face of climate change. The ice sheets in Greenland and Antarctica are melting at an ever-quickening pace. Since 1992, they have contributed 11 millimeters — or one-fifth — of the total global sea-level rise, say the researchers. The two polar regions are now losing mass three times faster than they were 20 years ago, with Greenland alone now shedding ice at about five times the rate observed in the early 1990s. This latest estimate, published this week in Science, draws on up to 32 years of ice-sheet simulations and 20 years of satellite data to give an estimate two to three times more accurate than that in the last IPCC report."

Highway To Sell: AC/DC iTunes Snub Finally Over 247

Posted by timothy
from the genuine-angus dept.
Hugh Pickens "The LA Times reports that after years of stubbornly arguing that iTunes was, in the words of singer Brian Johnson, 'going to kill music if they're not careful,' AC/DC has reached a deal with Apple to sell its entire catalog — 16 studio albums, four live albums and three compilations — through the service. AC/DC was one of the last high-profile holdouts from the digital music marketplace, outlasting the Beatles, Led Zeppelin, and Pink Floyd, all of which jumped into the realm long after much of the population had accepted the downloading future. Angus Young, AC/DC's lead guitarist (known for wearing a schoolboy's uniform when performing), had long argued against hawking the band's music because he didn't like the idea of allowing for individual song downloads — submitting that the group's albums were designed to be listened to from beginning to end. 'It's like an artist who does a painting,' he said in 2008. 'If he thinks it's a great piece of work, he protects it. It's the same thing: This is our work.'"

Comment: Re: Backup Heating (Score 1) 473

I installed a wood burning insert into our fireplace. It has a large glass door so you can still see the flames for ambiance. It is 70% efficient, using a blower to circulate heat and is designed to reignite smoke to reduce particulates. I gather wood locally from trees my neighbors cut down after summer storms.

So I can heat the house in the event of a power outage. I also have an inverter so I can use my prius as a generator to run the blower, router, wifi.

The generation of random numbers is too important to be left to chance.
