Shhhhhhhhh: don't tell them that our 3rd rock has been secretly colonized by denizens from the 2nd rock, who have already begun terraforming...errrr...venusforming(?) it, and have made tremendous progress in that direction in just a bit less than a single century, local time...
What if the 3rd rock was a colony by proxy? What if we are the martians?
You might be onto something, but that would only hold if the car was parked on private property. This might include most parking lots, since they are not public streets vs. on-street parking or on public/government land.
It does not even hold on private property in many areas and there is no such requirement. In some areas, cops can and do ticket cars in driveways for expired registration or other violations.
Hate to break it to you guys, but reusable rockets were demonstrated over 25 years ago. Yeah, I know, amazing stuff.
A solid-fuel booster that splashes down in seawater so it takes months of replacing corroded parts to ready it for a new duty cycle is not "reusable" in any modern sense.
Nor is one where the sections are so bend out of round that the press used to straighten them is jury rigged to use more force then the reliability requirements allowed.
The Space Shuttle was a reusable launch system, but launches were pretty expensive (in terms of kg to orbit), and reusing the SRBs did very, very little to bring those costs down. In contrast, using refurbished Falcon 9 first stages turns out to be a real cost saver. The amazing part is not just the technology (especially landing those stages on land or barges, which is where the cost savings come in), but the economics as well.
NASA was deceptive at best when referring to the Space Shuttle as reusable and Feynman's report touched on this. Major systems like the SSMEs had to be completely refurbished after every launch because the original design goals of reusability and reliability were not met; they always returned with damage which normally would have been considered a failure but NASA redefined failure as a maintenance issue.
The average commute time in th United States is 26 minutes one way. Yes, there are plenty of exceptions, but the fact is that an EV would be suitable vehicle for most Americans. Not all, but most.
I agree and the part I find amusing about this is that short range EVs which meet this requirement will make longer commutes less economical. This will hurt rural areas.
There is no way the car (traction battery) owner is not going to get screwed by the power companies in this deal.
The other problem is the extra expense of implementing bidirectional power conversion at each charger and car whether it is used or not. At least it gets used with a stationary battery bank.
Nukes are useful, necessary even for a number of reasons. First and foremost nukes deliver power and lots of it all the time, which heavy industry absolutely requires;
"Advanced grid management technology" is a nice way of saying shutting off the customer's power. Very few heavy industries can put up with that. Very few people will put up with that.
The dilemma of cooling nuclear power plants is an artificial one. "Ecologically sensitive" is code for animals are more important than people. A choice between rolling backouts and a lower standard of living versus insignificant ecological damage is not going to be good for the ecology.
Why not apply a Pigovian tax to encourage a market friendly solution which prevents ecological damage? Because they have no interest in such a thing; they just want nuclear power gone at any cost. Isn't it odd that a Pigovian tax is not used on fossil fuels? I wonder why that is.
batteries are not yet capacious or cheap enough to store power in sufficient quantity to make up for the patchiness of renewables.
Others disagree and it is difficult to get trustworthy numbers.
Electro-chemical storage has always been very expensive but with high power density making it suitable for load balancing once the power electronics became economical but not so good for bulk storage and this is *with* the advantages of flow batteries in bulk applications. Maybe the economy of scale available to lithium batteries in traction applications will change this.
Secondly, the world still has a lot of high-level nuclear waste that really needs destroying in fast-neutron reactors;
They are expensive and dangerous. It would make more sense to just drop the waste into a subduction (The word "subduction" is not in the Moz dictionary... WTF) zone and wave goodbye to it.
I agree but it would be wasteful. High level radioactive waste has almost all of the original nuclear energy in it and it is not that difficult or expensive to store compared to dumping it into subduction zone.
Renewables are cheaper than nukes, so nukes won't help more than they will.
They may be until distribution and storage costs are accounted for.
The obvious solution is to put solar panels over parking lots. It's cheap to put them there, and doing so actually extends the life of the paving surface. This would work especially well in Israel, where there is plenty of insolation.
The panels would have to provide enough energy during the time the vehicle is parked which is not going to happen unless the area taken up by the panels is much larger than the area taken up by the vehicles in the parking lot. So now the parking lot takes up several times as much space.
It would be more economical to use the panels to feed the power grid displacing the variable costs of fuel in fossil fueled power plants (not nuclear) and put them where it is convenient albeit with an additional distribution cost to charge the cars. Distributed solar might even be more economical although oddly enough it comes with distribution costs as well.
And you don't need storage to go with it, because the cars are the storage.
I hope you were not referring to the terrible idea of using traction batteries for grid storage. Centralized interests like the power company will make sure it just becomes another way to extract rents. It will be a terrible deal for whoever owns the battery.
Uh, how can they charge her with obstructing anything when they a) don't know what was on the phone and b) had any assurance they could even access they phone (especially as TFA notes that they were so clueless that they didn't toss it in a Faraday bag). There may or may not have been evidence.
This all part of the game, and this round went to the bad guys.
Since they had probable cause to seize and search the phone, the burden of knowing that evidence was on the phone was already met.
For example if they already know what they can expect to find (I.e they have examples of say child pornography coming from your IP), then a judge can compel you to divulge your keys or be held in contempt of court.
Knowing what is on the phone leads to probable cause for a warrant to seize and search it.
Knowing that it is your phone leads to the forgone conclusion doctrine so requiring your to unlock or produce the pass code does not reveal anything new.
Speaking of microwaves, I am puzzled as to why we consider them shielded enough for human safety --haven't done any research though. There is a kindof urban legend I've heard here from the days of wifi B and G that congested home routers sometimes drop connections whenever someone's zapping food in the nearby ovens.
The level of leakage needed to interfere with 2.4 GHz WiFi is very low compared to the level needed to become a safety hazard.
The spectrum analyser function of a Ubiquiti access point can easily see the distinctive leakage from a microwave over at a considerable distance. They really trash the whole 2.4 GHz band.
The ISM bands were intended for applications where there was really no alternative to allowing high levels of leakage which make communication applications unreliable. If this is unacceptable for your product, then a different spectrum allocation is needed.
More personally, owning recent tech shows motive for worry whenever I walk by an active set (2 different brands thru the years) while listening to various bluetooth devices (headphones, speakers). My audio playback starts stuttering till I walk away. So are all of them poorly shielded and leaking acceptable non-cooking radiation?
It is pretty much an impossible problem; the choke ring used to shield the door seam has a finite attenuation so there is always a minimum level of leakage. 900 MHz microwave ovens used finger stock (a 900 MHz choke ring would be too large) which would work much better however the finger stock is fragile and prone to damage compromising its performance which is why 900 MHz microwave ovens are no longer in use.
Tin Foil doesn't, but Copper Tape does wonders. From GPS to Cell to everything else, line a box with it and you're golden (its a staple at work for "no signal" tests).
The problem whether tin, aluminum, or copper foil is used is the seam which acts as a slot antenna. This is especially a problem with aluminum because of its durable insulating oxide.
RF shielding enclosures often use conductive finger stock or braid to bridge across seams limiting the size of any inadvertent slot antenna.
A microwave oven with the door closed also would work, and no you don't need to plug it in, and you might not like what happens if you turned it on.
A 900MHz microwave oven which uses finger stock to seal the door seam against RF would work great but they are long obsolete because the exposed and fragile finger stock along the inside of the door was easily damaged allowing leakage. This is a shame because they heated food more effectively than higher frequency ovens.
2.4 GHz microwave ovens use a choke ring folded into the door which is why the doors are so thick but the choke ring only works over a narrow frequency range and to a lessor extent its odd harmonics. Outside of that, the seam in the door acts as a slot antenna preventing good attenuation.
A small bag made of continuous metal mesh (Faraday bag?) with a conductive seam would work great though. The various metalized plastic bags I have tried have been hit or miss and not as effective but someone undoubtedly makes one which is suitable.
There are methods to use a password which is too long to remember. They come down to storing the password in a physical form which if accessed improperly is destroyed or plausibly destroyed like a deck of cards, stack of bills, or set of code books.
Of course it is inconvenient if you can only unlock your phone once at the beginning of the day and the court may not care but at least it gives you a chance to establish plausible deniability. It would be more suitable to a fully encrypted file server, workstation, or desktop.
Now, these satellite services are great for under-served areas of the world. The problem is, the customers available, those willing and able to pay, and needing service in those under-served geographies, there aren't that many of them really. Most people in the under-served geographies are poor, or they don't need this service. But put all that aside for a moment and consider this. The majority of people worldwide live in (or near) cities and already have internet and cell and WiFi service.
The people paying the telephone and cable monopolies are under served also.
Congress has regularly raided the USPS's coffers for the last 30 years, but in 2006 G.W. Bush required that they pre-fund the full expected value of their retirement accounts (about $55-$70 billion) up front costing them $5.5 to $5.8 billion every year since 2007.
All other federal agencies are allowed to invest a smaller amount each year under the assumption that those investments will grow to meet their final needs, much like regular folks do with their 401(k) and IRA's.
Nothing changed. The USPS retirement funds buy U.S. treasuries putting the money exactly where Congress can get to it. The fund is composed of IOUs.
So, it's Mountain Standard Time year round, same as Arizona which doesn't use DST.
It puts two issues together - the time change issue and the issue of DST or no DST. As well as allowing the legislature to change the time of DST start and end. That's the ultimate problem with California propositions - they're not written by a committee who has sat down and thought things through, they're often written by a disgruntled person with a gripe who's able to raise money to get it on the ballot. Many of these propositions when passed are quickly struck down by the courts because they violate the California constitution, or they conflict with other laws, etc. This one seriously feels like a bunch of drunks in a bar hashed things out on the back of a napkin.
I might believe it was written by those anticipating selling new clocks and replacements for hardware which cannot be updated. Maybe Congress can get into the act and change it again like they did in 2005; I need an excuse to waste money on new clocks.

Come on, I would think that regulations should be used to stop all of that bad air. Issue solved.
Not if the bad air is coming from the regulators.
Fuel reduction in about 80% of the burnt areas is a federal responsibility.
It is too bad then that California is so anti-federalism.
On the one side we have all the states in history. Many wielding the power of life and death.
On the other side, we have one programmer with money and his engineer friends.
The result?
Every country on the planet is being outperformed by a handful of engineers and techs.
PS - that company is run by an engineer who happens to be a woman.
Everything that programmer and engineer have accomplished can be undone by lawyers and politicians. Range safety is very important.

How will you get the waste to the subduction zone? Asking for a friend.
Drop it from the surface inside of an armored and guided perpetrator with high sectional density.
Nukes are useful, necessary even for a number of reasons. First and foremost nukes deliver power and lots of it all the time, which heavy industry absolutely requires;
