Run that through a database containing everyone on the planet, and you get a few million positive hits, all but one an error.
No you won't. There are 13 standard Loci with something like 10 Alleles or more at each marker. So that is something like the chance of a "random" match as one in 10^-12. This is both correct and wrong. First many of these 13 markers have more than 10 alleles and the provability is closer to something like 10^-15. Its wrong in that its not random, you share about 50% of these markers with your father for example. Even population wide this does reduce the randomness. Then there is a birthday paradox. But that does not apply in this case since you are matching the database to a given profile. So with 7 billion humans in the database, chances are that there is just one hit. Not millions. You would be very lucky to get more than one.
When comparing to a 100 suspects that are not related (remember the profile will tell us if they are related.) You are more like 99.99999999% sure. Even far more than that.
These days the MHG is replaced with a compulsator. Same idea however and can be matched to a rail gun easier. However the real big problem is arcing and turning the projectile into plasma, or just generally making a mess of it. Next is the massive amounts of rail erosion you get from the arcing.
It is easy to imagine some kind of cruise missile missile hybrid with much longer ranges. Launch 100 or even 200 of them at once. They don't need to be that cheap if they can take out a carrier with high probability. You still win on economics, and well also moral grounds.
A work colleague is getting a new mac laptop that was priced up today. It is 2x more expensive than the equivalent pc. These prices are from the internal IT department. What i don't get is the retina displays match with fairly mediocre graphics cards. You got the pixels, give em' the fill rate!
Debunk all you like. Apple products are expensive when it comes to buying stuff. If you think its worth it, good for you.
Recall that the topic is that apple are trying to doge their legal warranty obligations. Why pay a premium for something the company doesn't even want to stand by?
Only if you sell high. MS was worth far more some years back. Look at that stock price now. You really think it will be different for apple? I don't think so.
Running the numbers is not that hard. Lets say orbital velocity of 7.5km/s and a mass of 2000kg. E_k=mv^2/2 and that gives us 56GJ. Its 15MWh. Its a bit, but not totally insane. Now if we have a 15m rail gun to accelerate that with, assuming constant acceleration. From 2as=v^2 we get a=1.875x10^6 m/s^2 and from s=at^2/2 t=4ms. So that is a power of 14TW. Its a bit. But we have things that do this. For example the Z machine is more than 200TW IIRC. But then its only "on" for 100s of nanoseconds.
Consider that this would be run from a complusator. A 100T rotor spinning at 1000ms can hold a max of 50GJ. So yea, 56GJ is really a lot. However my reading on rail guns is that they would use lighter faster projectiles with less total energy. For comparison 56GJ is equivalent to about 13 Tons of TNT.
Blender is not CAD anyway. I know of only commercial products that are really CAD capable. Its just a lot of work that the OS community has never really got stuck into. Perhaps because if you have a CNC machine, the software cost is not really a big issue.
I have worked for these companies... I have also signed NDA's. I doubt any of these links will go far enough. It would shock you. Example: Why research a cure when a treatment even with side effects are far more profitable.
But memorizing and manually writing in addresses is? Seriously if the main complaint of v6 is the address are too long to type/memorize, then i think they got it about right.
You know that not so long ago another company had a huge market cap, it was bigger than apples once adjusted for inflation. Their market cap is *lot* smaller now. You think this will turn out different? I don't think so.
that's one thing the patent system currently does right, which is giving inventors some protection against being ripped off by predators.
No it doesn't. Unless your legal team and legal budget are bigger than who ever is ripping you off, the current system provides zero effective protection. It has always been a system by the big players (and their lawyers) for the big players.
Yes it does. There is a truthiness to this claim that is very prevalent. However it is just that. Truthiness. In particular i have never heard anyone claim they wont require constant monitoring.
First off the total cycle waste of a Thorium cycle is about the same as a reprocessed Uranium cycle. That is because it is a reprocessing cycle. 233U Fission products are almost identical to 235U products. The idea is you save on actinides since you don't need to have any 238U. But these can be burnt in a liquid salt reactor as well.
Second is the radiation and decay heat is also the same as a normal plant, after all without delayed neutrons you can't control the reaction at all, and we are still burning Uranium after all. The shutdown issues if the passive and non passive cooling systems don't work are the same. A few 10s of MW of heat without cooling tends to melt pretty much anything. ie you can get a core breach if things don't work as planed. Pro tip: things always eventually don't work as planed.
Anything causing any type of core breach is just as disastrous. Fluoride based salts react with water (say in the air) to produce even more corrosive acid that the original salt and produces hydrogen. So hydrogen explosions are still a risk. Chloride based salts are soluble in water so can easily spreed the fission products into any accessible water table. The fuel can still boil and produces all sort of other issues with insufficient cooling.
There are other questions that just have not been answered. Can we get a breading ratio of 1? This has never been done. The very small demo reactor experiment did not do any breading. Can in situ reprocessing work as planed. How will the high level gammas affect operational costs (the same gammas that make it harder to make bombs). There are a lot of unknowns that without building a full prototype we simply don't have answers for other than speculation.
In fact the vast majority of the benefits of a LFTR are in fact from the LFR part and you get the same benefits from a LFUR. Liquid salt reactors are a part of a larger class of homogeneous reactors and have quite a long list of advantages, probably more so now with the costs of certifying and validating fuel elements. Perhaps the biggest advantage is that a fast reactor can safely burn actinides, ie problematic long term nuclear waste we already have a lot of. This is a difficult control problem in solid fuel fast reactors.
Especially if your transmission capitol cost go up an order of magnitude, it may well be cheaper to just live with the 10% lose (is it really that high?). Electric motors and generators are in the same boat. They are already in the 90%+ range. Power density would be a bonus.
However magnetic energy storage would have quite an impact.
A lot of people forget this. What is illegal with copying? Why should it be illegal? Patents, copyrights and trademarks are give narrow situations where its illegal to copy. Not broad "copying is wrong" rubbish.
Those of us who live under it certainly do. 30 years ago it took an hour in the sun to for me to get burnt. Now it takes 10 minutes.
You do realize that even when the hole was at its largest (in winter) its was still the better part of 1000 miles from inhabitant land. Unless you count Antarctica as inhabited in the winter... also sunburn is not an issue in the Antarctica winter as it turns out.
The problem with "i remember when....but now" is that its mostly crap. We don't remember well at all and it is *not* data.
3-5km is not a giant. Also it is a long way from a ELE. Also this is *not* like motorcycles. We have machines looking for them, and they have a very distinct "signature".
Considering you only get about 1kg of lift per m3 with He or Hydrogen, even a tiny car with a single passenger is going to be massive. Lets 100kg for the person and lets be really generous with the rest and say another 100kg. So we need about 200m3 to lift that. Or a cube about 6meters on the side. And lets be honest, you are not going only need 200kg of lift, more like 1000kg.

For something moving at 11200m/s with a mass of 1815kg, gives a KE of 113GJ, or more than 3 orders of magnitude more than what you have.

But a 100J of heat is *not* the same as 100J of work.
All electric heaters are 100% efficient.
Not really. Work is not the same as heat. Using a heat pump is 3x or more efficient. Pumping heat is a better use of work than just heating.
Or am I expected to build a microCVD unit ...
I have always wanted to do that. I mean how hard can it be? less than x nanometers of vibration, purity of gasses etc in the 6 to 12 nines range. ;D
