Without a breakthrough in energy storage density, I don't think the 500-mile battery is practical unless one drives that distance on a very regular basis. It just adds too much weight to already-heavy vehicles. You would also need the chemistry to be capable of much quicker charging. When we get to millions of EVs on the roads, having to stop for 30+ min to get a 1/2 - 3/4 charge is going to create traffic bottlenecks in a great many places.
I see 2 possible solutions to that - battery swap, which so far has proven unpopular, or a supplementary source such as the Phinergy aluminum-air fuel cell. That latter was demonstrated on a 1,000 mile drive using a prototype that weight just about 100 lbs, negligible weight compared to the total vehicle load. The downside is that, for now, it's not rechargeable.
Tesla made ONE model of sporty car but it was never intended to be their main business. And that was a small 2-seater that's really no match for the cars that made Porsche famous. I expect Tesla to continue making & improving the Model S but they're not really competing in Porsche's space, except (possibly) against the Panamera and if the Model X catches on, the Cayenne. And it not likely that Porsche will deliver its 1st all-electric car at a competitive price point to even the top-end Model S.
Even the guys who drive hundreds of cars, like the MotorTrend or Car & Driver reviewers, say that instant torque smile never fades. If you floor the accelerator in any vehicle, you're wasting energy. At least you get some of that back in an EV through regen.
Porsche intends to build an ALL-ELECTRIC SPORTS car, not a "Tesla competitor". They're not even calling this "Mission E" a sedan. And you can be quite sure, it'll be hella more expensive than a Model S.
I don't think 1GB & dual-core ARM is going to cut it for respectable NAS performance. That's pretty much what older versions of the LaCie NAS had under the hood and the performance was lame. And they'd better get the security right. Nothing like having someone root your router AND have access to your porn stash in one hack.
Woolsey is part of the reason Americans were in favor of invadiing Iraq; he made comments about Iraqi complicity in 9/11 the VERY NEXT DAY and on several more occasions over the next few years. Whatever he wishes for Snowden should be tried on him 1st.
I'm pretty sure the Nexus switches run Linux on the bare metal but the AsyncOS that powers the Ironport Web & Email appliances is supposedly running on top of FreeBSD. But in neither case does the customer have access to underlying OS - as far as I'm aware.
It should read "Justice officials fear public will find out nation's biggest wiretap is illegal and action. Which is unlikely to happen or be effective if it does"
Fellow down the block has a Hummer H2 6.2L - this thing is HUGE, the rear brake lights are above my shoulders. I don't think these have been sold since 2010 but he keeps his looking like its brand-new. Must be close to 3000 kg curb weight.
I have this problem with devices that need older versions of Java. I keep around a Win 2003 VM just to be able to use web interfaces for some old production hardware that the business doesn't want to pay to replace until it dies.
I'm well aware of the history, promise and hype around molten-salt reactors and have seen several of Kirk Sorensen's presentations and some of the old ORNL docs. I think MSRs / LFTRs / whatever are worthy of research and development and would encourage serious spending dollars be allocated.
BUT...... the only known MSR was a test machine, never used thorium, never produced electricity and was frequently shut down. That's not good enough to displace - yet - to displace other proven technologies be they traditional nuclear or not.
What's needed is to have another MSR/LFTR built, say 20 - 50 MW, run it for at least 3 years with >60% uptime , connected to varying loads and let it be the primary electricity source for something near-mission-critical, say a military base. Pull that off while demonstrating the advantages of the tech before trying to sell it as the power plant of the future.
The French nuclear plants, although a remarkable achievement, have had mutiple shutdowns of many units due to lack of adequate cooling - just when they're most needed ( during summer heat waves ).
"supplementing their "nuclear free" grid capacity with power generated in french nuclear plants" - it's true that a very significant chunk of French nuke power is exported - because it's too difficult to ramp more than a few plants up & down so the benefits cut both ways.
Yes, Denmark produced 110% of its demands - for less than 2 hours, on a warm afternoon with historic low demands
Actually, it peaked at 140% and it was high for a LOT longer than "less than 2 hours" From a low of 390 MW at 10pm on July 7th, 2015, wind power production on the DK-West grid rose to 1 GW by 2am on July 8th, then to 2 GW by 8am and peaked just over 3GW by 3pm on July 9th. At no time between 9am on July 8th and 7pm on July 10th did wind power on DK-West drop below 2GW and for the bulk of that period of two and a half days it was above 2.6GW. Gross power consumption on DK-West varied from 1.8GW - 2.8GW during that time.
For DK-East, wind power production from 6am on July 8th to 9pm on July 10th varied from 400MW to 920MW and for >80% of the time was above 800MW. DK-East gross power consumption was from 1 - 1.6GW during that period.
"Interconnectors allowed 80% of the power surplus to be shared equally between Germany and Norway, which can store it in hydropower systems for use later. Sweden took the remaining fifth of excess power". Looks like it was of some benefit to the neighbors. and "The figures emerged on the website of the Danish transmission systems operator, energinet.dk, which provides a minute-by-minute account of renewable power in the national grid. The site shows that Denmark’s windfarms were not even operating at their full 4.8GW capacity at the time of yesterday’s peaks" (from http://www.theguardian.com/env...)
Perhaps but the dramatic price drops that have been seen with wind & PV have yet to happen for solar thermal. I've heard that a big part of the problem is there's not enough standardization - every project, especially when it's by different companies, is built like a one-off plant.

I think that was a joke referencing VW's dieselgate.

There are charging spots at a LOT of groceries where people the people who own Teslas shop.

Trust the man who built Facebook rather than learn how to socialize in person to be in agreement with a Rube Goldberg solution.

Perhaps America is ready for President Newt "Moonbase" Gingrich.

Your palm print or retina scan would have the same limitations.
"Better would be to blame idiot politicians that make stupid rules"
Companies work really hard at making sure those idiot politicians get elected and quite often also write the legislation for them.
That "cyclical cool down" was a period of intense volcanism, lower insolation and significantly lower GHGs
Judging by the ever-increasing, ever more weird malarkey coming out his mouth, he needs a brain implant asap.

That is one theory - that the universe is some sort of hologram.
I think that Stephen Wolfram may be a proponent of this hypothesis.
And creating new particles, phases of matter, wormholes, dimensions as we get closer to unraveling its secrets?

It took them 8 years to get the final 20% done?
They should have just started over with a Gen 3 reactor.
