Back in 2006 Musk laid out his 10-year plan (frighteningly accurate) as part of laying out the efficiency numbers for EV vs. Hybrid which puts EV at ~2x better even back then.
So yes, EV moves the pollution upstream. Oh, AND: - upstream means outside of major metro areas where many people are impacted - is at least 2x more efficient well to wheels - can benefit from large, consolidated investment in power plants to increase efficiency/reduce pollution - can use solar to greatly reduce pollution AND work off-grid - can use nuclear power as well to vastly reduce pollution
Oh please, hospitals are still the low hanging fruit. Doctors who can quote body parts I can't pronounce and didn't know exist can't manage to remember a moderately complex password for more than 15 seconds...much less change it on occasion. I'm trolling a bit, but the number of hospital devices still in use that are set to default logins, passwords, pins or the like is astounding.
I'll say that hardened targets are still hugely susceptible to an individual with moderate inside knowledge. Spear-phishing is a joke compared to what someone COULD be writing if they knew how to use spellcheck.
It's more than just budgets though. It's the mindset of the end users (security is annoying) and the middle to senior managers (personal agenda >>>> usefulness) that's leaving huge holes. It amazes me that more Bad Things don't happen both where I work and elsewhere.
Because they drop their devices and don't have an adequate case to protect it.
Same reason so many micro-USB and lightning connectors/wires (and Mac power bricks etc.) get FUBARed. People twist them to hell and simply abuse them. I've had the same like-new lightning wire in daily use + travel for at least a year while my GF kills the one that's in the car every couple months.
USB-C is coming in the generation of products launching now. Dell's entire new business line has them all.
If we develop practical self-replicating robots (since we can 'almost' do a proof of concept self-replicating one now) If we develop technology to plausibly 'mine' surface material (i.e. moon regolith) that's not more involved in shipping material
Bonus if: If we can make both happen in a hard vacuum where no one has set foot in decades Extra bonus: if we can prove out transmitting GW (much less TW) power from geo-stat orbit
Then of course let's do this. In reality this sounds like any of a dozen sci fi books I've read. Send magical self-replicating robots off to do some job and let them multiply. I'm surprised they didn't include nano-something to make it even more gooder.
Any major aspect of this project would be easily be worth many times over the $350 projected cost.
I can see a 32GB option as realistic. Memory does start adding cost, though not nearly as much as the markup.
16GB though...fills up ridiculously fast if you take more than a very few pictures. Even keeping SMS/iMessage/whatsapp/kik/etc. conversations turns multi-GB very quickly. 16GB iphone = ~10Gb available storage = warning messages before you know it
Electrical Efficiency is loosely coupled to volumetric efficiency. We're talking about an inverter roughly the size of a fist that's outputting 2kW. Without very high efficiency your cooling solution would be larger than your inverter. A moderate size CPU cooler (sinking ~65w) is the size of this whole inverter.
The rules require efficiency >95% which is typical for high efficiency inverter systems. At that, the primary benefit to higher efficiency is lowered cooling requirements (i.e. size) which is the primary goal of the competition.
So the rules basically *do* set teams out to maximize efficiency. Having small, highly efficient inverters is useful is many applications (solar, vehicular, UPS, etc.)
As for Google's exact benefit? I could see them running these in datacenters: deliver 450VDC rails to all your racks and power them off a hockey puck inverter or two. Simple to scale - add more battery, more racks with inverters as needed. Everything becomes modular.
Beyond that, solar and larger UPS systems typically run at 450VDC - so this means you can also scale your UPS and solar installation in conjunction with your datacenter. Basically combine all the technologies together without requiring large monolithic components. Ok, TLDR my own post.
26' uHaul truck (since we're geeks not CDL drivers) holds 7400lbs or 3357KG uSDXC weights.25g so you can carry 13,428,000 (by volume is 2x higher but...max weight) 2,685,600,000GB or 2.7EB
Let's say we're going 100km/hr and going NYC to SF for 4700km or 47 hours or 169,200 seconds So that's about 16000GB/s
The approximate bandwidth of a 26' uHaul is 127tbps.
Those cards are $100 each so it'd only cost $1.3 billion (plus gas, tolls, and rental) Let me know next time you want to move 2.7EB from NYC to SF - I'm down.
If you patent an edison style bulb specifically then sure, a fluorescent bulb isn't covered.
If you patent an elongated-sphere shaped-device with contacting points on one end which fits into a receptacle that has a threading mechanism to effect electrical contact and securing said device which is designed to emit light...then yeah, you're screwed. Welcome to recent patents.
Instead of designing a light bulb and patenting it, companies draw up a vague representation that covers every and any imaginable permutation of their idea and they somehow get a patent for THAT.
On a slightly more serious note, just because someone has the background to create an encryption system (micro-scale security) does not mean they have the background to speak towards privacy or macro-scale information security.
Obligatory (bad) car analogy:
Would you trust Charles Goodyear (patented vulcanization) or even Henry Ford to write traffic laws? While bad analogies are bad, the underlying point is that having tangential knowledge gives you nearly zero USEFUL knowledge and insight to the relevant topic.
Not to play grammar nazi... but you're interSECTING about half of the radiated power. You're certainly not interCEPTING half of it.
This assumes cell phones use omni-directional antennas which I rather expect is the case. If your body intercepted half the radiated power then holding the phone to your ear would result in a lot of dropped calls in mediocre coverage areas.
I'm not about to pay 42 bucks to read the study so I can't speak to it directly. With that said, there's been numerous OTHER studies which have entirely refuted these types of claims.
There's also plenty of evidence that god exists depending on where you set the bar for 'evidence.'
Once the legal door has been opened (it becomes OK to require companies build back doors)... Once the technical door has been opened (backdoor to firmware)...
Open either door and there's no closing them. What's truly ironic is there was a huge uproar a year or so about backdoors in network gear coming out of china... and now the US is literally asking for the same thing to be created for them.
That's a lot of guesswork coupled with a bad assumption.
Nuclear fallout from an airburst is greatly reduced compared to a groundburst. The idea that they'd horribly contaminate lots of China is completely incorrect. Consider there's a huge mall a few blocks from where the Hiroshima bomb was dropped. It's a thriving city. Lots of people live there.
There's also an enormous risk with NOT retaliating. You effectively remove your nuclear deterrent but showing the world it's possible to use a nuclear weapon without an immediate retaliation in kind. I'd say this is a bigger risk than blasting anything worthwhile in NK into ash and dealing with China's bitching...
Which really... If a major US city just got hit with a nuclear bomb, no one is going to give a damn about china crying about some minor fallout while the US dealt with 1M+ casualties and fallout of it's own.
I'd say about the ONLY conceivable option to avoid a retaliatory strike would be the immediate, complete, and total surrender by NK.
About 200 pounds to orbit which, if memory serves, would be a higher trajectory than you want/need for attacking with an ICMB. Thus, I expect you could substantially increase that by going suborbital.
They're unlikely to have the tech but 200 pounds is in the neighborhood for a semi-modern reentry vehicle (the W76 at 100kT yield is 376 pounds, manufactured starting in 1978).
Unlikely they're there yet but that tech is 40 years old and they have a lot of advantages that didn't exist in the 70's during the original development.
Yep, just enough chance. A 1% chance that a major west coast city would be hit with a nuclear bomb is more than sufficient. Considering that LA individually has a GDP ~50x higher than all of DPRK the risk/return is staggering.
The reason it's newsworth but not war-worthy is they're liquid fueled rockets. Front standby, the launch cycle for a modern liquid fueled rocket is on the order of days, while solid rocket launch cycle is a matter of minutes.
You can bet there's plenty of attention being paid. If they pair a potential nuclear weapon with a "peaceful satellite launch platform" we'll have a cruise missile on target as soon before they're even close to a launch. If they start developing solid rockets in bunkers similar to the minuteman nuclear platforms in the US...you can bet they will be on the receiving end of some high explosives.
Please...the newspapers (or collectively media) are so incredibly biased... and people are so uneducated about our own election process it boggles the mind.
Hilary "won" by a hair. If this was the superbowl then sure, declare victor and hand out rings.
It's not though.
Instead, she got 23 delegates to Bernie's 21. All of which is counted towards the overall total, of which there are 4714. Hilary has (drumroll...) 0.04% more of the total delegates than Bernie. BFD
It's like claiming a 100% increase in sales because you sold two bananas instead of one. I know Iowa is typically used as an indicator... and it'll certainly go a long way to follow theory that when the media is already using words like winner while the difference between candidates is extraordinarily small.
He's mad that out of 3000 (or was it 5000) people he was #1344 in line to test drive.
Boo hoo. That means you're still ahead of at least half of the people. Sure, 1000+ people aren't going to get to test drive a car in one night...we get that. Why exactly does he feel that entitled and special that, of all the other thousands of people who put down a deposit, he should be a priority?
I'd bet he is (well, was) the 1344th person to put a deposit on the X.
Folks like to use privilege and entitlement as dirty words these days...well THIS is a PERFECT example. Some peoples business is not worth taking, case and point.
You can buy a fully completed one that will beat the pants off almost any modern sports car for ~50K. Granted it has no roof and only seats two... but to some that's a feature not a problem:)
I've toyed with the idea of getting a Factory 5 kit for a few years now. The lack of garage/build space in brooklyn makes it a bit less practical though.
I had to laugh when 'pretty reliable' is 'astonished and gratified' to a 4-5 hour drive without something breaking.
It's an iconic car and some people will gladly pay for one with all it's flaws. I wouldn't pay $100K for those flaws though. Plenty of others with extra garage space, time, and plenty of extra money apparently will though.
If I could sell 30M in cars built from spare parts I probably got for a song...I surely would too.

It's still better to pump natural gas into a cogen plant and charge an EV than gas into your car.
All the better if you're charging off solar of cours.e
Back in 2006 Musk laid out his 10-year plan (frighteningly accurate) as part of laying out the efficiency numbers for EV vs. Hybrid which puts EV at ~2x better even back then.

So sure, enjoy your smog...erm smug Mazda 2.

Nothing can beat the bandwidth of a truck full of blu rays.
