And it is also not life. Could replicators be made? perhaps (that is a big perhaps, try starting with raw SiO2 and create semiconductor grade silicon). But this is *not* life as people are talking about. Also it doesn't work as well as you would think, a von neumann replicator perhaps (ie provide a lot of pre built parts).
Well really bad scifi aside (Dr Who, star trek). A proper look at elemental abundance and chemical properties, something that we do know with a lot of accuracy, non carbon based life forms are a pipe dream. The only proposed element is silicon, and it is shit. Total shit. It simply does not form the range of compounds you need. Does not have any kind of useful solvent. doesn't naturally form anything interesting even in the slightest. And where you have silcon you have carbon. In fact silicon is far more prevalent on earth than carbon, yet life only uses it for shells of some diatoms.
Compare to carbon, where we have giant clouds of interesting organic molecules just floating around in space, that can bond to itself and other elements in an infinite range of ways with and equally diverse range of properties. Water is a *very* good and strong solvent and highly polar. But in a pinch i guess say methane may work as a solvent. But it wouldn't be as good as water.
In short there are very good reasons to believe all life in this universe will be carbon based. But lets not forget, that gives a huge scope for varation from what we see here on earth. With equal certainty all alien life will not be biocompatible with us. If we found anything with DNA, RNA etc, it would be very strong grounds to suspect common origin.
Some people i work with here, are astrobiologist. Honestly carbon is as impressive as a bable fish.
It is not FUD. It has been shown in proper peer reviewed journals that you can do this. Claiming its FUD because you see no proof that anyone *is* doing it, is *not* how you do security. Do you really think the Feds are going to tell you.
Right now the tor network is just to small to hide in. There is not enough onion.
I don't think you understand the quantities involved. A 1 GW plant would use kgs of He3 per year. Yet getting even 1 kg of tritium is huge amount and would require a long time. Fission reactors don't make many neutrons per unit power compared to fusion and a lot of neutrons are lost to other poisons etc. This means the total yields for these breeder rods and other methods (no LFTR are not especially good for tritium production) is very low. In fact most tritium we ever had was about 200kg and its much much less now and that was mostly from bombs. It is very useful in small quantities as a booster in fission bombs. But this would be very impractical method of breeding He3.
It is fairly easy to prove that a sandbox can't be proven to be secure either. There are lots of ideas and stuff. But unless you can prove bug free, you can't prove secure. And you can't prove bug free.
Its about use. The most used tend to have the most problems. But that is probably also a little unfair. Who the hell used applets in the last 10 years? My guess is a lot of those bugs are applet related.
Clearly you haven't been to europe. They are talking about capacity. In Berlin for example, the outer ring train track has a train every min, that can hold a *lot* of people. On the order of 1000 from a guess. That is 60,000 people an hour.
While we are still a long way from strong ai, and there are still things squishy wet evolved slow biocomputers can do better than silicon. Driving is not one of them. Or at least won't be very soon.
Seriously? You think that we can't handle 1 foot over 100 years? Do you have waves where you are? or storms? Did you know that we have less floods now because we built a shit ton of stuff to stop flooding!
Think what the world looked like 100 years ago, and stop assuming we are all going to stand around with our thumbs up our arse waiting for 100 years to get our ankles wet.
This, the storms in the pacific got water under our house in Niue, almost 15m above sea level, because of storm surge and big arse waves. Most houses blew away. Also some of the small islands complaining about sea level rise are sinking far faster anyway. In other words is has nothing to do with global warming.
And no please don't start with the "Hurricanes caused by global warming". Most of the advertised effects need at least another 50 years to manifest themselves. That is from the models.
This is correct. A nd universe is encoded, or can be "encoded" ie all information on a (n-1)d surface. So all the information that can be contained in a volume is proportional to the surface containing that volume.
He3 and DD have at least a 65x power density penalty. No mater what magic is used in the reactor. It will produce the better part of 100x less power. Making it the better part of 100x more expensive.
WTF. The island and Moon are both pretty equal on the science footing. aka shit. What would you expect. Oh and when it comes to any of these styles of movies, there are plenty that are similar that came first.
Only it is bullshit. It is not hard. He3 in moons surface is in the 1 part per billion to 50 parts per billion. ie almost nothing. Also it only in the first 1-5 meters of surface. It would be one of human kinds biggest mining operation ever. And would provide enough He3 to run 2 -3 power stations *only*. Oh and you can run a mining operation like that with only one person, you can run it with non and have a teleoperated robot or something.
Moon the movie was a lot of things. Hard SF it was not.
Even if you did have a He3 fusion reactor, mining He3 is still a really stupid idea. It would be easier to breed he3 in a specalized DD reactor. And if you can do He3 you can do DD.
You don't understand the physics. He3/D reaction and the DD reaction have comparable reaction cross sections, but you get far more xray losses from He3 options making the whole thing far far harder.
DD fusion has a branching probability of 50% with half resulting in a He3 and the other half a T. That is right He3 is DD fusion *ash*. Which can then also be burnt as well as the T.
You cannot simply mine He3. It is in the parts per billion range, and even at 100% efficiency you would need one of the biggest mines ever just to run a few plants back on earth. On the moon. It is stupid. It is sheer desperation on part of people who need a reason to go to the moon. There really isn't one outside tourism.
DD fusion is about 10x harder than DT fusion and has 65x less power for the same size power plant. We can't even do DT fusion. In fact DT fusion needs to be so exceedingly easy before we could even consider DD or He3 or DHe3 fusion.
Sooo your comparing the Ultraviolet Catastrophe which had really good solid data to back up the problems with mismatching of theory? To an over unity device with no credible data to back it up? Really? REALLY? sheesh.
well it is not really that far over budget. If you check it properly rather than the media version of budget. But yes it does show that this sort of cooperation is expensive just in overheads alone. I mean they took 10 years to decide where to build it! Shesh. That is a lot of wages that need a budget for something that hadn't even broken ground yet.
So we should assume something that would create free energy and violate every single well defined "engineering rule" out? It would mean every bridge and building will fall down. Conservation of momentum and energy would be false if this worked. Period. Also there ZERO theory behind the emdrive. None. Oh he had some hashed out bullshit that was shown to be wrong a while back. But they can't fix what is wrong with it. Basically they guy couldn't do his math so said "whoo dude i found a propellantless drive".
Good engineers and scientists don't assume that when they get a results like say free energy or momentum that they invented something. They assume they made a mistake. And the few that don't at least acknowledge a mistake after it was pointed out to them.
Seems old people can be suckers too. I heard there is this nigerian prince who wants to give you money. You may want to get in touch with him mr low UID.

There is more evidence of dark matter than global warming. Look it up.
Perhaps you could use your fingers, try typing and look it up. The universe is not required to conform to what you feel is reasonable or sensable.

you're also not very anonymous on tor. People that want to track you just run a lot of nodes and traffic analysis away.

Yea like i went out after the movie an immediately got a flying bike, and flew to the cinema next town over and watch a bond film. Oh wait...

This is a cool engine. But the ion engines are sort of quite different in that they have only a "top gear" and it is much higher than a VASIMR.
well it is not really that far over budget. If you check it properly rather than the media version of budget. But yes it does show that this sort of cooperation is expensive just in overheads alone.
